The Perfect Server – Ubuntu 14.10 with Apache, PHP, MySQL, PureFTPD, BIND, Postfix, Dovecot and ISPConfig


This tutorial shows how to install an Ubuntu 14.10 (Utopic  Unicorn) server (with Apache2, BIND, Dovecot) for the installation of ISPConfig 3, and how to install ISPConfig 3. ISPConfig 3 is a webhosting control panel that allows you to configure the following services through a web browser: Apache or nginx web server, Postfix mail server, Courier or Dovecot IMAP/POP3 server, MySQL, BIND or MyDNS nameserver, PureFTPd, SpamAssassin, ClamAV, and many more. This setup covers the installation of Apache (instead of nginx), BIND (instead of MyDNS), and Dovecot (instead of Courier).

 

1. Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100 and the gateway 192.168.0.1 . These settings might differ for you, so you have to replace them where appropriate.  Before proceeding further you need to have a basic minimal installation of Ubuntu 14.10 as explained in tutorial.

2. Edit /etc/apt/sources.list And Update Your Linux Installation

Edit /etc/apt/sources.list. Comment out or remove the installation CD from the file and make sure that the universe and multiverse repositories are enabled. It should look like this:

nano /etc/apt/sources.list

# 

# deb cdrom:[Ubuntu-Server 14.10 _Utopic Unicorn_ - Release amd64 (20141022.2)]/ utopic main restricted

#deb cdrom:[Ubuntu-Server 14.10 _Utopic Unicorn_ - Release amd64 (20141022.2)]/ utopic main restricted

# deb-src http://extras.ubuntu.com/ubuntu utopic main

Then run

apt-get update

to update the apt package database and

apt-get upgrade

to install the latest updates (if there are any). If you see that a new kernel gets installed as part of the updates, you should reboot the system afterwards:

reboot

 

3. Change The Default Shell

/bin/sh is a symlink to /bin/dash, however we need /bin/bash, not /bin/dash. Therefore we do this:

dpkg-reconfigure dash

Use dash as the default system shell (/bin/sh)? <– No

If you don’t do this, the ISPConfig installation will fail.

 

4. Disable AppArmor

AppArmor is a security extension (similar to SELinux) that should provide extended security. In my opinion you don’t need it to configure a secure system, and it usually causes more problems than advantages (think of it after you have done a week of trouble-shooting because some service wasn’t working as expected, and then you find out that everything was ok, only AppArmor was causing the problem). Therefore I disable it (this is a must if you want to install ISPConfig later on).

We can disable it like this:

service apparmor stop
update-rc.d -f apparmor remove
apt-get remove apparmor apparmor-utils

 

5. Synchronize the System Clock

It is a good idea to synchronize the system clock with an NTP (network time protocol) server over the Internet. Simply run

apt-get install ntp ntpdate

and your system time will always be in sync.

 

6. Install Postfix, Dovecot, MySQL, phpMyAdmin, rkhunter, binutils

For installing postfix we need to stop and remove sendmail

service sendmail stop; update-rc.d -f sendmail remove

Now we can install Postfix, Dovecot, MySQL, rkhunter, and binutils with a single command:

apt-get install postfix postfix-mysql postfix-doc mariadb-client mariadb-server openssl getmail4 rkhunter binutils dovecot-imapd dovecot-pop3d dovecot-mysql dovecot-sieve sudo

You will be asked the following questions:

New password for the MySQL “root” user: <– yourrootsqlpassword
Repeat password for the MySQL “root” user: <– yourrootsqlpassword
Create a self-signed SSL certificate?: <– Yes
Host name: <– server1.example.com
Local only: <– OK
General type of mail configuration: <– Internet Site
System mail name: <– server1.example.com

Next open the TLS/SSL and submission ports in Postfix:

nano /etc/postfix/master.cf

Uncomment the submission and smtps sections as follows – add the line -o smtpd_client_restrictions=permit_sasl_authenticated,reject to both sections and leave everything thereafter commented:

[...]
submission inet n       -       -       -       -       smtpd
  -o syslog_name=postfix/submission
  -o smtpd_tls_security_level=encrypt
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
#  -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
smtps     inet  n       -       -       -       -       smtpd
  -o syslog_name=postfix/smtps
  -o smtpd_tls_wrappermode=yes
  -o smtpd_sasl_auth_enable=yes
  -o smtpd_client_restrictions=permit_sasl_authenticated,reject
#  -o smtpd_reject_unlisted_recipient=no
#  -o smtpd_client_restrictions=$mua_client_restrictions
#  -o smtpd_helo_restrictions=$mua_helo_restrictions
#  -o smtpd_sender_restrictions=$mua_sender_restrictions
#  -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
#  -o milter_macro_daemon_name=ORIGINATING
[...]

Restart Postfix afterwards:

service postfix restart

We want MySQL to listen on all interfaces, not just localhost, therefore we edit /etc/mysql/my.cnf and comment out the line bind-address = 127.0.0.1:

nano /etc/mysql/my.cnf

[...]
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
#bind-address           = 127.0.0.1
[...]

Then we restart MySQL:

service mysql restart

Now check that networking is enabled. Run

netstat -tap | grep mysql

The output should look like this:

root@server1:~# netstat -tap | grep mysql
tcp        0      0 *:mysql                 *:*                     LISTEN      24603/mysqld
root@server1:~#

7. Install Amavisd-new, SpamAssassin, And Clamav

To install amavisd-new, SpamAssassin, and ClamAV, we run

apt-get install amavisd-new spamassassin clamav clamav-daemon zoo unzip bzip2 arj nomarch lzop cabextract apt-listchanges libnet-ldap-perl libauthen-sasl-perl clamav-docs daemon libio-string-perl libio-socket-ssl-perl libnet-ident-perl zip libnet-dns-perl

The ISPConfig 3 setup uses amavisd which loads the SpamAssassin filter library internally, so we can stop SpamAssassin to free up some RAM:

service spamassassin stop
update-rc.d -f spamassassin remove

 To Run clamav use

freshclam
service clamav-daemon start

8. Install Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear, And mcrypt

Apache2, PHP5, phpMyAdmin, FCGI, suExec, Pear, and mcrypt can be installed as follows:

apt-get install apache2 apache2-doc apache2-utils libapache2-mod-php5 php5 php5-common php5-gd php5-mysql php5-imap phpmyadmin php5-cli php5-cgi libapache2-mod-fcgid apache2-suexec php-pear php-auth php5-mcrypt mcrypt php5-imagick imagemagick libapache2-mod-suphp libruby libapache2-mod-python php5-curl php5-intl php5-memcache php5-memcached php5-ming php5-ps php5-pspell php5-recode php5-sqlite php5-tidy php5-xmlrpc php5-xsl memcached

You will see the following question:

Web server to reconfigure automatically: <– apache2
Configure database for phpmyadmin with dbconfig-common? <– No

Then run the following command to enable the Apache modules suexec, rewrite, ssl, actions, and include (plus dav, dav_fs, and auth_digest if you want to use WebDAV):

a2enmod suexec rewrite ssl actions include cgi

a2enmod dav_fs dav auth_digest

Next open /etc/apache2/mods-available/suphp.conf

nano /etc/apache2/mods-available/suphp.conf

… and comment out the <FilesMatch “\.ph(p3?|tml)$”> section and add the line AddType application/x-httpd-suphp .php .php3 .php4 .php5 .phtml – otherwise all PHP files will be run by SuPHP:

<IfModule mod_suphp.c>
    #<FilesMatch "\.ph(p3?|tml)$">
    #    SetHandler application/x-httpd-suphp
    #</FilesMatch>
        suPHP_AddHandler application/x-httpd-suphp

    <Directory />
        suPHP_Engine on
    </Directory>

    # By default, disable suPHP for debian packaged web applications as files
    # are owned by root and cannot be executed by suPHP because of min_uid.
    <Directory /usr/share>
        suPHP_Engine off
    </Directory>

# # Use a specific php config file (a dir which contains a php.ini file)
#       suPHP_ConfigPath /etc/php5/cgi/suphp/
# # Tells mod_suphp NOT to handle requests with the type <mime-type>.
#       suPHP_RemoveHandler <mime-type>
</IfModule>

Restart Apache afterwards:

service apache2 restart

If you want to host Ruby files with the extension .rb on your web sites created through ISPConfig, you must comment out the line application/x-ruby rb in /etc/mime.types:

nano /etc/mime.types

[...]
#application/x-ruby                             rb
[...]

(This is needed only for .rb files; Ruby files with the extension .rbx work out of the box.)

Restart Apache afterwards:

service apache2 restart

 

8.1 Xcache

Xcache is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It’s similar to other PHP opcode cachers, such as eAccelerator and APC. It is strongly recommended to have one of these installed to speed up your PHP page.

Xcache can be installed as follows:

apt-get install php5-xcache

Now restart Apache:

service apache2 restart

 

8.2 PHP-FPM

Starting with ISPConfig 3.0.5, there is an additional PHP mode that you can select for usage with Apache: PHP-FPM.

To use PHP-FPM with Apache, we need the mod_fastcgi Apache module (please don’t mix this up with mod_fcgid – they are very similar, but you cannot use PHP-FPM with mod_fcgid). We can install PHP-FPM and mod_fastcgi as follows:

apt-get install libapache2-mod-fastcgi php5-fpm

Make sure you enable the module and restart Apache:

a2enmod actions fastcgi alias
service apache2 restart

 

8.3 Additional PHP Versions

Starting with ISPConfig 3.0.5, it is possible to have multiple PHP versions on one server (selectable through ISPConfig) which can be run through FastCGI and PHP-FPM. To learn how to build additional PHP versions (PHP-FPM and FastCGI) and how to configure ISPConfig, please check this tutorial: How To Use Multiple PHP Versions (PHP-FPM & FastCGI) With ISPConfig 3 (Ubuntu 12.10) (works for Ubuntu 14.10 as well).

9. Install Mailman

Since version 3.0.4, ISPConfig also allows you to manage (create/modify/delete) Mailman mailing lists. If you want to make use of this feature, install Mailman as follows:

apt-get install mailman

Select at least one language, e.g.:

Languages to support: <– en (English)
Missing site list <– Ok

Before we can start Mailman, a first mailing list called mailman must be created:

newlist mailman

root@server1:~# newlist mailman
Enter the email of the person running the list:
 <– admin email address, e.g. listadmin@example.com
Initial mailman password: <– admin password for the mailman list
To finish creating your mailing list, you must edit your /etc/aliases (or
equivalent) file by adding the following lines, and possibly running the
`newaliases’ program:

## mailman mailing list
mailman:              “|/var/lib/mailman/mail/mailman post mailman”
mailman-admin:        “|/var/lib/mailman/mail/mailman admin mailman”
mailman-bounces:      “|/var/lib/mailman/mail/mailman bounces mailman”
mailman-confirm:      “|/var/lib/mailman/mail/mailman confirm mailman”
mailman-join:         “|/var/lib/mailman/mail/mailman join mailman”
mailman-leave:        “|/var/lib/mailman/mail/mailman leave mailman”
mailman-owner:        “|/var/lib/mailman/mail/mailman owner mailman”
mailman-request:      “|/var/lib/mailman/mail/mailman request mailman”
mailman-subscribe:    “|/var/lib/mailman/mail/mailman subscribe mailman”
mailman-unsubscribe:  “|/var/lib/mailman/mail/mailman unsubscribe mailman”

Hit enter to notify mailman owner… <– ENTER

root@server1:~#

Open /etc/aliases afterwards…

nano /etc/aliases

… and add the following lines:

[...]
## mailman mailing list
mailman:              "|/var/lib/mailman/mail/mailman post mailman"
mailman-admin:        "|/var/lib/mailman/mail/mailman admin mailman"
mailman-bounces:      "|/var/lib/mailman/mail/mailman bounces mailman"
mailman-confirm:      "|/var/lib/mailman/mail/mailman confirm mailman"
mailman-join:         "|/var/lib/mailman/mail/mailman join mailman"
mailman-leave:        "|/var/lib/mailman/mail/mailman leave mailman"
mailman-owner:        "|/var/lib/mailman/mail/mailman owner mailman"
mailman-request:      "|/var/lib/mailman/mail/mailman request mailman"
mailman-subscribe:    "|/var/lib/mailman/mail/mailman subscribe mailman"
mailman-unsubscribe:  "|/var/lib/mailman/mail/mailman unsubscribe mailman"

Run

newaliases

afterwards and restart Postfix:

service postfix restart

Finally we must enable the Mailman Apache configuration:

ln -s /etc/mailman/apache.conf /etc/apache2/conf-available/mailman.conf

This defines the alias /cgi-bin/mailman/ for all Apache vhosts, which means you can access the Mailman admin interface for a list at http://<vhost>/cgi-bin/mailman/admin/<listname>, and the web page for users of a mailing list can be found at http://<vhost>/cgi-bin/mailman/listinfo/<listname>.

Under http://<vhost>/pipermail you can find the mailing list archives.

Restart Apache afterwards:

service apache2 restart

Then start the Mailman daemon:

service mailman start

 

10. Install PureFTPd And Quota

PureFTPd and quota can be installed with the following command:

apt-get install pure-ftpd-common pure-ftpd-mysql quota quotatool

Edit the file /etc/default/pure-ftpd-common

nano /etc/default/pure-ftpd-common

… and make sure that the start mode is set to standalone and set VIRTUALCHROOT=true:

[...]
STANDALONE_OR_INETD=standalone
[...]
VIRTUALCHROOT=true
[...]

Now we configure PureFTPd to allow FTP and TLS sessions. FTP is a very insecure protocol because all passwords and all data are transferred in clear text. By using TLS, the whole communication can be encrypted, thus making FTP much more secure.

If you want to allow FTP and TLS sessions, run

echo 1 > /etc/pure-ftpd/conf/TLS

In order to use TLS, we must create an SSL certificate. I create it in /etc/ssl/private/, therefore I create that directory first:

mkdir -p /etc/ssl/private/

Afterwards, we can generate the SSL certificate as follows:

openssl req -x509 -nodes -days 7300 -newkey rsa:2048 -keyout /etc/ssl/private/pure-ftpd.pem -out /etc/ssl/private/pure-ftpd.pem

Country Name (2 letter code) [AU]: <– Enter your Country Name (e.g., “DE”).
State or Province Name (full name) [Some-State]:
<– Enter your State or Province Name.
Locality Name (eg, city) []:
<– Enter your City.
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
<– Enter your Organization Name (e.g., the name of your company).
Organizational Unit Name (eg, section) []:
<– Enter your Organizational Unit Name (e.g. “IT Department”).
Common Name (eg, YOUR name) []:
<– Enter the Fully Qualified Domain Name of the system (e.g. “server1.example.com”).
Email Address []:
<– Enter your Email Address.

Change the permissions of the SSL certificate:

chmod 600 /etc/ssl/private/pure-ftpd.pem

Then restart PureFTPd:

service pure-ftpd-mysql restart

root@server1:~# service pure-ftpd-mysql restart
Restarting ftp server: Running: /usr/sbin/pure-ftpd-mysql-virtualchroot -l mysql:/etc/pure-ftpd/db/mysql.conf -l pam -8 UTF-8 -u 1000 -E -O clf:/var/log/pure-ftpd/transfer.log -Y 1 -B
root@server1:~#

Edit /etc/fstab. Mine looks like this (I added ,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 to the partition with the mount point /):

nano /etc/fstab

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/mapper/server1--vg-root /               ext4    errors=remount-ro,usrjquota=quota.user,grpjquota=quota.group,jqfmt=vfsv0 0       1
# /boot was on /dev/sda1 during installation
UUID=9b8299f1-b2a2-4231-9ba1-4540fad76b0f /boot           ext2    defaults        0       2
/dev/mapper/server1--vg-swap_1 none            swap    sw              0       0

To enable quota, run these commands:

mount -o remount /

quotacheck -avugm
quotaon -avug

 

11. Install BIND DNS Server

BIND can be installed as follows:

apt-get install bind9 dnsutils

 

12. Install Vlogger, Webalizer, And AWstats

Vlogger, webalizer, and AWstats can be installed as follows:

apt-get install vlogger webalizer awstats geoip-database libclass-dbi-mysql-perl

Open /etc/cron.d/awstats afterwards…

nano /etc/cron.d/awstats

… and comment out everything in that file:

#MAILTO=root

#*/10 * * * * www-data [ -x /usr/share/awstats/tools/update.sh ] && /usr/share/awstats/tools/update.sh

# Generate static reports:
#10 03 * * * www-data [ -x /usr/share/awstats/tools/buildstatic.sh ] && /usr/share/awstats/tools/buildstatic.sh

 

13. Install Jailkit

Jailkit is needed only if you want to chroot SSH users. It can be installed as follows (important: Jailkit must be installed before ISPConfig – it cannot be installed afterwards!):

apt-get install build-essential autoconf automake1.9 libtool flex bison debhelper binutils-gold

cd /tmp
wget http://olivier.sessink.nl/jailkit/jailkit-2.17.tar.gz
tar xvfz jailkit-2.17.tar.gz
cd jailkit-2.17
./debian/rules binary

You can now install the Jailkit .deb package as follows:

cd ..
dpkg -i jailkit_2.17-1_*.deb
rm -rf jailkit-2.17*

14. Install fail2ban

This is optional but recommended, because the ISPConfig monitor tries to show the log:

apt-get install fail2ban

To make fail2ban monitor PureFTPd and Dovecot, create the file /etc/fail2ban/jail.local:

nano /etc/fail2ban/jail.local

[pureftpd]
enabled  = true
port     = ftp
filter   = pureftpd
logpath  = /var/log/syslog
maxretry = 3

[dovecot-pop3imap]
enabled = true
filter = dovecot-pop3imap
action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp]
logpath = /var/log/mail.log
maxretry = 5

[postfix-sasl]
enabled  = true
port     = smtp
filter   = postfix-sasl
logpath  = /var/log/mail.log
maxretry = 3

Then create the following two filter files:

nano /etc/fail2ban/filter.d/pureftpd.conf

[Definition]
failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.*
ignoreregex =

nano /etc/fail2ban/filter.d/dovecot-pop3imap.conf

[Definition]
failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.*
ignoreregex =

Add the missing ignoreregex line in the postfix-sasl file:

echo “ignoreregex =” >> /etc/fail2ban/filter.d/postfix-sasl.conf

Restart fail2ban afterwards:

service fail2ban restart

15 Install SquirrelMail

To install the SquirrelMail webmail client, run

apt-get install squirrelmail

Then configure SquirrelMail:

squirrelmail-configure

We must tell SquirrelMail that we are using Dovecot-IMAP/-POP3:

Now we will configure SquirrelMail so that you can use it from within your web sites (created through ISPConfig) by using the /squirrelmail or /webmail aliases. So if your website is www.example.com, you will be able to access SquirrelMail using www.example.com/squirrelmail or www.example.com/webmail.

SquirrelMail’s Apache configuration is in the file /etc/squirrelmail/apache.conf, but this file isn’t loaded by Apache because it is not in the /etc/apache2/conf.d/ directory. Therefore we create a symlink called squirrelmail.conf in the /etc/apache2/conf.d/ directory that points to /etc/squirrelmail/apache.conf and reload Apache afterwards:

cd /etc/apache2/conf-available/
ln -s ../../squirrelmail/apache.conf squirrelmail.conf
service apache2 reload

Now open /etc/apache2/conf.d/squirrelmail.conf

 nano /etc/apache2/conf-available/squirrelmail.conf

… and add the following lines to the <Directory /usr/share/squirrelmail></Directory> container that make sure that mod_php is used for accessing SquirrelMail, regardless of what PHP mode you select for your website in ISPConfig:

[...]
<Directory /usr/share/squirrelmail>
  Options FollowSymLinks
  <IfModule mod_php5.c>
    AddType application/x-httpd-php .php
    php_flag magic_quotes_gpc Off
    php_flag track_vars On
    php_admin_flag allow_url_fopen Off
    php_value include_path .
    php_admin_value upload_tmp_dir /var/lib/squirrelmail/tmp
    php_admin_value open_basedir /usr/share/squirrelmail:/etc/squirrelmail:/var/lib/squirrelmail:/etc/hostname:/etc/mailname
    php_flag register_globals off
  </IfModule>
  <IfModule mod_dir.c>
    DirectoryIndex index.php
  </IfModule>

  # access to configtest is limited by default to prevent information leak
  <Files configtest.php>
    order deny,allow
    deny from all
    allow from 127.0.0.1
  </Files>
</Directory>
[...]

Create the directory /var/lib/squirrelmail/tmp

mkdir /var/lib/squirrelmail/tmp

… and make it owned by the user www-data:

chown www-data /var/lib/squirrelmail/tmp

Next we need to enable the squirrelmail with apache2.

a2enconf squirrelmail

Reload Apache again:

service apache2 reload

That’s it already – /etc/apache2/conf.d/squirrelmail.conf defines an alias called /squirrelmail that points to SquirrelMail’s installation directory /usr/share/squirrelmail.

You can now access SquirrelMail from your web site as follows:

http://192.168.0.100/squirrelmail
http://www.example.com/squirrelmail

You can also access it from the ISPConfig control panel vhost (after you have installed ISPConfig, see the next chapter) as follows (this doesn’t need any configuration in ISPConfig):

http://server1.example.com:8080/squirrelmail

If you’d like to use the alias /webmail instead of /squirrelmail, simply open /etc/apache2/conf.d/squirrelmail.conf

nano /etc/apache2/conf-available/squirrelmail.conf

… and add the line Alias /webmail /usr/share/squirrelmail:

Alias /squirrelmail /usr/share/squirrelmail
Alias /webmail /usr/share/squirrelmail
[...]

Then reload Apache:

service apache2 reload

Now you can access Squirrelmail as follows:

http:// 192.168.0.100/webmail
http://www.example.com/webmail
http://server1.example.com:8080/webmail
(after you have installed ISPConfig, see the next chapter)

34

If you’d like to define a vhost like webmail.example.com where your users can access SquirrelMail, you’d have to add the following vhost configuration to /etc/apache2/conf.d/squirrelmail.conf:

nano /etc/apache2/conf.d/squirrelmail.conf

[...]
<VirtualHost *:80>
  DocumentRoot /usr/share/squirrelmail
  ServerName webmail.example.com
</VirtualHost>

Of course, there must be a DNS record for webmail.example.com that points to the IP address that you use in the vhost configuration. Also make sure that the vhost webmail.example.com does not exist in ISPConfig (otherwise both vhosts will interfere with each other!).

Now reload Apache…

service apache2 reload

… and you can access SquirrelMail under http://webmail.example.com

 

16. Install ISPConfig 3

To install ISPConfig 3 from the latest released version, do this:

cd /tmp
wget http://www.ispconfig.org/downloads/ISPConfig-3-stable.tar.gz
tar xfz ISPConfig-3-stable.tar.gz
cd ispconfig3_install/install/

The next step is to run

php -q install.php

This will start the ISPConfig 3 installer. The installer will configure all services like Postfix, Dovecot, etc. for you. A manual setup as required for ISPConfig 2 (perfect setup guides) is not necessary.

root@server1:/tmp/ispconfig3_install/install# php -q install.php

The installer automatically configures all underlying services, so no manual configuration is needed.

You now also have the possibility to let the installer create an SSL vhost for the ISPConfig control panel, so that ISPConfig can be accessed using https:// instead of http://. To achieve this, just press ENTER when you see this question: Do you want a secure (SSL) connection to the ISPConfig web interface (y,n) [y]:.

Afterwards you can access ISPConfig 3 under http(s)://server1.example.com:8080/ or http(s)://192.168.0.100:8080/ ( http or https depends on what you chose during installation). Log in with the username admin and the password admin (you should change the default password after your first login):

The system is now ready to be used.

 

 

17. Additional Notes

17.1 OpenVZ

If the Ubuntu server that you’ve just set up in this tutorial is an OpenVZ container (virtual machine), you should do this on the host system (I’m assuming that the ID of the OpenVZ container is 101 – replace it with the correct VPSID on your system):

VPSID=101
for CAP in CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE CHOWN DAC_READ_SEARCH SETGID SETUID NET_BIND_SERVICE NET_ADMIN SYS_CHROOT SYS_NICE
do
vzctl set $VPSID –capability ${CAP}:on –save
done
