Installing Lighttpd With PHP5 And MySQL Support On CentOS 6.0


Lighttpd is a secure, fast, standards-compliant web server designed for speed-critical environments. This tutorial shows how you can install Lighttpd on a CentOS 6.0 server with PHP5 support (through FastCGI) and MySQL support.

I do not issue any guarantee that this will work for you!

 

1 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

 

2 Installing MySQL 5.0

First we install MySQL 5.0 like this:

yum install mysql mysql-server

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

chkconfig –levels 235 mysqld on
/etc/init.d/mysqld start

Set passwords for the MySQL root account:

mysql_secure_installation

[root@server1 ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we’ll need the current
password for the root user.  If you’ve just installed MySQL, and
you haven’t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on…

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] <– ENTER
New password: <– yourrootsqlpassword
Re-enter new password: <– yourrootsqlpassword
Password updated successfully!
Reloading privilege tables..
… Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] <– ENTER
 … Success!

Normally, root should only be allowed to connect from ‘localhost’.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] <– ENTER
 … Success!

By default, MySQL comes with a database named ‘test’ that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] <– ENTER
 – Dropping test database…
… Success!
– Removing privileges on test database…
… Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] <– ENTER
 … Success!

Cleaning up…

All done!  If you’ve completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

[root@server1 ~]#

3 Installing Lighttpd

Lighttpd is not available from the official CentOS 6.0 repositories, but from the RPMforge repositories (see http://dag.wieers.com/rpm/FAQ.php#B2 for instructions). We install the RPMforge package for RHEL 6 which works for CentOS 6.0 as well:

If you are on an x86_64 system:

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
rpm -Uhv rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

If you are on an i386 system:

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i386.rpm
rpm -Uhv rpmforge-release-0.5.2-2.el6.rf.i386.rpm

Afterwards, we can install Lighttpd like this:

yum install lighttpd

Then we create the system startup links for Lighttpd (so that Lighttpd starts automatically whenever the system boots) and start it:

chkconfig –levels 235 lighttpd on
/etc/init.d/lighttpd start

If Lighttpd fails to start with the following error message…

(network.c.203) socket failed: Address family not supported by protocol

… open /etc/lighttpd/lighttpd.conf

vi /etc/lighttpd/lighttpd.conf

… and change server.use-ipv6 from enable to disable:

[...]
##
## Use IPv6?
##
server.use-ipv6 = "disable"
[...]

Then try to start Lighttpd again – it should now work without any problem:

/etc/init.d/lighttpd start

Now direct your browser to http://192.168.0.100, and you should see the following page:

1

Lighttpd’s default document root is /srv/www/lighttpd on CentOS 6.0 (there’s no index file in that directory like index.html, that’s why you get a 404 Not Found error), and the configuration file is /etc/lighttpd/lighttpd.conf.

 

4 Installing PHP5

We can make PHP5 work in Lighttpd through FastCGI. Therefore we install the packages lighttpd-fastcgi and php-cli:

yum install lighttpd-fastcgi php-cli

5 Configuring Lighttpd And PHP5

To enable PHP5 in Lighttpd, we must modify two files, /etc/php.ini and /etc/lighttpd/lighttpd.conf. First we open /etc/php.ini and add the line cgi.fix_pathinfo = 1 right at the end of the file:

vi /etc/php.ini

[...]
cgi.fix_pathinfo = 1

Then we open /etc/lighttpd/modules.conf and uncomment the line include “conf.d/fastcgi.conf”:

vi /etc/lighttpd/modules.conf

[…]
##
## FastCGI (mod_fastcgi)
##
include “conf.d/fastcgi.conf”
[…]

Next open /etc/lighttpd/conf.d/fastcgi.conf…

vi /etc/lighttpd/conf.d/fastcgi.conf

… and uncomment the fastcgi.server stanza – make sure you change the socket lines to /tmp/php-fastcgi-1.socket and /tmp/php-fastcgi-2.socket, and both bin-path lines must have the value /usr/bin/php-cgi:

[…]
fastcgi.server = ( “.php” =>
( “php-local” =>
(
“socket” => “/tmp/php-fastcgi-1.socket”,
“bin-path” => “/usr/bin/php-cgi”,
“max-procs” => 1,
“broken-scriptfilename” => “enable”,
)
),
( “php-tcp” =>
(
“host” => “127.0.0.1”,
“port” => 9999,
“check-local” => “disable”,
“broken-scriptfilename” => “enable”,
)
),

( “php-num-procs” =>
(
“socket” => “/tmp/php-fastcgi-2.socket”,
“bin-path” => “/usr/bin/php-cgi”,
“bin-environment” => (
“PHP_FCGI_CHILDREN” => “16”,
“PHP_FCGI_MAX_REQUESTS” => “10000”,
),
“max-procs” => 5,
“broken-scriptfilename” => “enable”,
)
),
)
[…]

Then we restart Lighttpd:

/etc/init.d/lighttpd restart
6 Testing PHP5 / Getting Details About Your PHP5 Installation

The document root of the default web site is /srv/www/lighttpd. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.

vi /srv/www/lighttpd/info.php

<?php
phpinfo();
?>

Now we call that file in a browser (e.g. http://192.168.0.100/info.php):

2

As you see, PHP5 is working, and it’s working through FastCGI, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don’t have MySQL support in PHP5 yet.

 

7 Getting MySQL Support In PHP5

To get MySQL support in PHP, we can install the php-mysql package. It’s a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:

yum search php

Pick the ones you need and install them like this:

yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc

Now restart Lighttpd:

/etc/init.d/lighttpd restart

Now reload http://192.168.0.100/info.php in your browser and scroll down to the modules section again. You should now find lots of new modules there, including the MySQL module:
