lighttpd, php-cgi, mysql setup for debian

This tutorial shows you how to setup lighttpd with php5-cgi and mysql-server on debian.
lighttpd runs with a small amount of ram, in this case I’ll setup the server on a 64mb ram bandwagonhost vps.

1. Installing lighttpd with php5-cgi and mod_evasive

At first, we install lighttpd, php5-cgi and a couple of other modules:

apt-get install lighttpd php5-cgi php5-common

Now let’s configure the lighttpd server, we’ll also add some rate limiting just to prevent small http-floods to take down the server:

nano /etc/lighttpd/lighttpd.conf

Let’s add mod_fastcgi to the config to enable php and mod_evasive to add a small flood protection:

server.modules = (
 "mod_access",
 "mod_alias",
 "mod_compress",
 "mod_fastcgi",
 "mod_evasive",
 "mod_redirect",
 # "mod_rewrite",
 )

At the end of the file add:

evasive.max-conns-per-ip = 3
 fastcgi.server = ( ".php" => ((
 "bin-path" => "/usr/bin/php5-cgi",
 "socket" => "/tmp/php.socket"
 )))

Let’s check if php is working. Create a php info file:

echo "<?PHP phpinfo (); ?>" > /var/www/info.php

Now open http://yourip/info.php and see if the php-information is displayed.

2. Installation/Configuration of mysql-server

Let’s also install mysql-server and get a config which uses a small amount of memory.

apt-get install mysql-server

During the installation-process a window pops up that wants you to choose a password for the root mysql user.

Let’s use a small mysql-config to keep memory-usage low:

cp /usr/share/doc/mysql-server-5.*/examples/my-small.cnf /etc/mysql

Backup your old mysql config and replace it with the new one:

cd /etc/mysql
mv my.cnf my.cnf.backup
mv my-small.cnf my.cnf

Now restart the mysql-server:

service mysql restart

Let’s check the memory-usage in htop:

Looks good, doesn’t it?

 

That’s it, now you got a webserver with php and mysql running on your lowendbox.
