lighttpd is an open-source web server more optimized for speed-critical environments than common products while remaining standards-compliant, secure and flexible. This tutorial shows how you can install Lighttpd on a CentOS 6 server with PHP (PHP-FPM).

First, update CentOS to latest version, login root and type the following command

# yum update -y

Install some packages need for the following steps

# yum install wget make cpp gcc gcc-c++ -y

Make a folder where you will store lighttpd and php sources

# mkdir -p /opt/source

Installing Lighttpd

You need to download the latest lighttpd source from http://www.lighttpd.net/download into the /opt/source. Type the following command

# cd /opt/source
# wget http://download.lighttpd.net/lighttpd/releases-1.4.x/lighttpd-1.4.30.tar.gz

Extract lighttpd-1.4.30.tar.gz package

# tar zxvf lighttpd-1.4.30.tar.gz
# cd lighttpd-1.4.30

To build lighttpd, type the following command

# ./configure --prefix=/webserver/lighttpd --disable-ipv6
# make
# make install

During ./configure, you might get some errors like the following

...
configure: error: pcre-config not found, install the pcre-devel package or build with --without-pcre
...

To solve the problem, type the following command

# yum install pcre pcre-devel

...
configure: error: zlib-headers and/or libs where not found, install them or build with --without-zlib
...

To solve the problem, type the following command

# yum install zlib zlib-devel

...
configure: error: bzip2-headers and/or libs where not found, install them or build with --without-bzip2
...

To solve the problem, type the following command

# yum install bzip2 bzip2-devel

Configuring Lighttpd

Access to folder of lighttpd, where lighttpd installed [/webserver/lighttpd] and make dirs

# cd /webserver/lighttpd
# mkdir -p etc/init.d
# mkdir -p etc/sysconfig
# mkdir -p www/htdocs
# mkdir -p var/run
# mkdir -p var/log
# mkdir -p var/lock/subsys
# mkdir -p var/cache

Add a user called “lighttpd” and chown all dir made for lighttpd user

# useradd -s /sbin/nologin -d /webserver/lighttpd/www/ lighttpd
# chown lighttpd -R etc
# chown lighttpd -R var
# chown lighttpd -R www

Return back forder /opt/source/lighttpd-1.4.30 to copy configuration files

# cd /opt/source/lighttpd-1.4.30
# cp doc/config/modules.conf /webserver/lighttpd/etc/
# cp -r doc/config/conf.d /webserver/lighttpd/etc/
# cp -r doc/config/vhosts.d/ /webserver/lighttpd/etc/

Create default lighttpd configuration file: /webserver/lighttpd/etc/lighttpd.conf (download sample lighttpd.conf file). Type the following command

# wget http://www.lifelinux.com/wp-content/uploads/2012/04/lighttpd.conf_.txt -O /webserver/lighttpd/etc/lighttpd.conf

If you want to run lighttpd by default when the system boots, create file called lighttpd in /webserver/lighttpd/etc/init.d/

# vi /webserver/lighttpd/etc/init.d/lighttpd

Append following line

#!/bin/sh
#
# lighttpd     Startup script for the lighttpd server
#
# chkconfig: - 85 15

exit $RETVAL

Chmod lighttpd with executed permission and create symbolic link in “/etc/init.d”. Type the following command

# chmod +x /webserver/lighttpd/etc/init.d/lighttpd
# ln -s /webserver/lighttpd/etc/init.d/lighttpd /etc/init.d/lighttpd

Create file called “lighttpd” in /webserver/lighttpd/etc/sysconfig

# vi /webserver/lighttpd/etc/sysconfig/lighttpd

Append following line

LIGHTTPD_CONF_PATH=/webserver/lighttpd/etc/lighttpd.conf

To start lighttpd for the first time, type the following command

# /etc/init.d/lighttpd start

Install PHP (PHP-FPM)

Download latest version of PHP at http://download.php.net

# cd /opt/source
# wget http://www.php.net/get/php-5.3.10.tar.gz/from/ca.php.net/mirror

To Extract its, enter

# tar zxvf php-5.3.10.tar.gz
# cd php-5.3.10

To build PHP, I’ll create bash file called build.sh

# vi build.sh

Append following line

#!/bin/sh
"./configure" \
"--prefix=/webserver/php" \
"--enable-fpm" \
"--with-libdir=lib64" \

Type the following command to install PHP

# sh build.sh
# make
# make install

If you have problems building PHP then read the article. Next step, copy php.ini to /webserver/php/etc/, enter

# cp php.ini-production /webserver/php/etc/php.ini

Rename php-fpm.conf, enter

# cd /webserver/php/etc
# cp php-fpm.conf.default php-fpm.conf

Open php-fpm.conf, type

# vi php-fpm.conf

Append following line

[global]
pid = run/php-fpm.pid
error_log = log/php-fpm.log
[www]
listen = 127.0.0.1:9000
listen.allowed_clients = 127.0.0.1
user = nobody
group = nobody
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
pm.max_requests = 500

If you want to run PHP-FPM by default when the system boots, create file called php-fpm in /etc/init.d/

# vi /etc/init.d/php-fpm

Append following line

#! /bin/sh

### BEGIN INIT INFO

	;;

	*)
		echo "Usage: $0 {start|stop|force-quit|restart|reload}"
		exit 1
	;;

esac

Chmod php-fpm with executed permission, enter

# chmod +x /etc/init.d/php-fpm

To start PHP-FPM for the first time, type the following command

# /etc/init.d/php-fpm start

Configure PHP-FPM and Lighttpd working together

Uncomment the following line in /webserver/lighttpd/etc/modules.conf

##
## FastCGI (mod_fastcgi)
##
include "conf.d/fastcgi.conf"

Open /webserver/lighttpd/etc/conf.d/fastcgi.conf, and append following line

server.modules += ( "mod_fastcgi" )
fastcgi.server = ( ".php" =>
  ( "php-tcp" =>
    (
      "host" => "127.0.0.1",
      "port" => "9000"
    )
  )
)

Save and close the file. Type the following command to restart Lighttpd

# /etc/init.d/lighttpd restart

This completes the installation steps. To test php you can create a info.php file in the document root folder

# vi /webserver/lighttpd/www/htdocs/info.php

Append following line

<?php
phpinfo();
?>

If you see the above, you have completed a successful installation of lighttpd and php.

LAMP is essentially a server that runs Linux, Apache, MySQL and Php/Perl and is more commonly known as a LAMP server. This guide provides step-by-step instructions for installing a full-featured LAMP server on a CentOS 6 .0

1. Update system

Before proceeding to install, update the system with the following command

# yum update

2. Install and Configure the Apache Web Server

The Apache web server is the most popular server online, used on more than 70% of all servers connected to the World Wide Web. And there are good reasons for it: it’s free, it’s very stable, it delivers a great performance, it’s very customizable. To install the current version of the Apache web server use the following command

# yum install httpd

If you want to run Apache by default when the system boots, type the following command

# chkconfig httpd --level 2345 on

To start Apache for the first time, type the following command

# /etc/init.d/httpd start

3. Apache Web Server Security and Optimization

1. Disable any unnecessary apache modules, type the following command

# vi /etc/httpd/conf/httpd.conf

My example configuration is here

LoadModule auth_basic_module modules/mod_auth_basic.so
LoadModule auth_digest_module modules/mod_auth_digest.so
LoadModule authn_default_module modules/mod_authn_default.so
LoadModule authz_host_module modules/mod_authz_host.so
LoadModule authz_user_module modules/mod_authz_user.so
LoadModule authz_default_module modules/mod_authz_default.so
LoadModule include_module modules/mod_include.so
LoadModule log_config_module modules/mod_log_config.so
LoadModule env_module modules/mod_env.so
LoadModule mime_magic_module modules/mod_mime_magic.so
LoadModule expires_module modules/mod_expires.so
LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so
LoadModule setenvif_module modules/mod_setenvif.so
LoadModule mime_module modules/mod_mime.so
LoadModule status_module modules/mod_status.so
LoadModule autoindex_module modules/mod_autoindex.so
LoadModule info_module modules/mod_info.so
LoadModule negotiation_module modules/mod_negotiation.so
LoadModule dir_module modules/mod_dir.so
LoadModule actions_module modules/mod_actions.so
LoadModule alias_module modules/mod_alias.so
LoadModule rewrite_module modules/mod_rewrite.so

2. Optimize Timeout & KeepAlive
You need to control Timeouts & KeepAlive to improve server performance. Type the following command

# vi /etc/httpd/conf/httpd.conf

Find & Edit it as follows

Timeout 10
KeepAlive On
MaxKeepAliveRequests 200
KeepAliveTimeout 5

3. Optimize MPM (Multi-Processing Module)
Apache’s default installation of MPM Prefork. To optimize MPM Prefork, type the following command

# vi /etc/httpd/conf/httpd.conf

Find

<IfModule prefork.c>

Edit it as follows

<IfModule prefork.c>
    StartServers          5
    MinSpareServers      10
    MaxSpareServers      15
    ServerLimit         450
    MaxClients          450
    MaxRequestsPerChild   0
</IfModule>

Which,

# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# ServerLimit: maximum value for MaxClients for the lifetime of the server
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves

4. Enable Mod_rewite
To enable mod_rewirte, type the following command

# vi /etc/httpd/conf/httpd.conf

Find

<Directory "/var/www/html">

Edit it as follows

<Directory "/var/www/html">
    AllowOverride All
    Options -MultiViews -Indexes FollowSymlinks IncludesNoExec +Includes
<Limit GET POST OPTIONS PROPFIND>
    Order allow,deny
    Allow from all
</Limit>
<LimitExcept GET POST OPTIONS PROPFIND>
    Order deny,allow
    Deny from all
</LimitExcept>
</Directory>

5. Enable File Caching
Enabling file caching can greatly improve your site’s performance and speed. If you want to enable file caching, type the following command

# vi /etc/httpd/conf/httpd.conf

Find

<Directory "/var/www/html">

Edit it as follows

<Directory "/var/www/html">
    AllowOverride All
    Options -MultiViews -Indexes FollowSymlinks IncludesNoExec +Includes
<Limit GET POST OPTIONS PROPFIND>
    Order allow,deny
    Allow from all
</Limit>
<LimitExcept GET POST OPTIONS PROPFIND>
    Order deny,allow
    Deny from all
</LimitExcept>
<FilesMatch "\.(flv|swf|ico|gif|jpg|jpeg|png|html|css)$">  
	Header set Cache-Control "max-age=604800, public"  
</FilesMatch>
</Directory>

4. Install and Configure MySQL Database Server

MySQL Server is one of the most popular database servers in the world, especially for use with dynamic, content rich websites. To install MySQL database server use the following command

# yum install mysql mysql-server

After installing MySQL, I highly recommend to run mysql_secure_installation, a program that helps secure MySQL. Important points to note are:
1. Be sure that the root account has a secure password set.
2. Do not create an anonymous account, and if it exists, say “yes” to remove it.
3. If your web server and MySQL server are on the same machine, you should disable the network access.

If you want to run MySQL by default when the system boots, type the following command

# chkconfig mysqld--level 2345 on

To start MySQL for the first time, type the following command

# /etc/init.d/mysqld start

5. Installing and Configuring PHP

PHP is a general-purpose scripting language originally designed for web development to produce dynamic web pages. Many popular web applications like WordPress, Joomla, Drupal, OScommerce, Magento are written in PHP. To install PHP on CentOS use the following command

# yum install php53 php53-mysql

To create secure PHP configuration settings, type the following command

# vi /etc/php.ini

Find & Edit it as follows

allow_url_fopen = Off 
display_errors = Off 
display_startup_errors = Off 
log_errors = On 
error_reporting = E_ALL 
expose_php = Off 
magic_quotes_gpc = On 
magic_quotes_sybase = Off 
register_globals = Off
max_execution_time = 60
memory_limit = 64M

To prevent run PHP scripts with a different file extension, type the following command

# vi /etc/httpd/conf.d/php.conf

Find

AddHandler php5-script .php
AddType text/html .php

Replace it as follows

<FilesMatch \.php$>
	AddHandler php5-script .php
	AddType text/html .php
</FilesMatch>

Restart Apache to reload new configurations. Type the following command

# /etc/init.d/httpd restart
