Install LEMP (Linux, Nginx, MySQL 5.5.29, PHP 5.4.11) on RHEL/CentOS 5-6 & Fedora 18-12
This howto guide explains more deeply on how to install LEMP (Linux,Nginx,MySQL,PHP) on pre-installed Linux servers and installation instructions can be used on various Linux distribution such asRHEL 6.2/6.1/6/5.8,CentOS 6.2/6.1/6/5.8andFedora 12,13,14,15,16,17,18servers usingRemiandNginxrepositories withYUMcommand.
In this guide we use latestMySQL 5.5.29andPHP 5.4.11versions withPHP-FPMmodules with Nginx. So, before moving further for installation let’s discuss aboutNginxandPHP-FPM.
What is Nginx?
Nginx(Engine X) is open source robust light and high performance Web server, reverse proxy sever and also mail proxy server forHTTP,SMTP,POP3andIMAPprotocols. To know more about features visithttp://wiki.nginx.org/Overview
What is PHP-FPM?
PHP-FPMstands forFastCGI Process Manageris an alternativePHP FastCGIimplementation with some additional useful features for heavily loaded websites. For more information visithttp://php-fpm.org/
Step 1: Installing Remi Repository
## Install Remi Repository on Fedora 18, 17, 16, 15 ##
# rpm -Uvh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
# rpm -Uvh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm

# rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
Step 2: Installing Nginx Repository
Nginxrepository only needed inRHEL/CentOSdistributions. So, create a file called/etc/yum.repos.d/nginx.repoand add the following lines to it.
For RHEL 6.3/6.2/6.1/6/5.8
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/rhel/$releasever/$basearch/
gpgcheck=0
enabled=1
For CentOS 6.3/6.2/6.1/6/5.8
[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=0
enabled=1
Step 3: Installing Ngnix, MySQL 5.5.29, PHP 5.4.11 & PHP-FPM
## Installing on Fedora 12, 13, 14, 15, 16, 17, 18 ##
# yum --enablerepo=remi install nginx mysql mysql-server php php-common php-fpm
## Installing on RHEL/CentOS 5-6 ##
# yum --enablerepo=remi,remi-test install nginx mysql mysql-server php php-common php-fpm
Step 4: Installing PHP 5.4.11 Modules
## Installing on Fedora 12, 13, 14, 15, 16, 17, 18 ##
# yum --enablerepo=remi install php-mysql php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml php-pecl-apc php-cli php-pear php-pdo
## Installing on RHEL/CentOS 5-6 ##
# yum --enablerepo=remi,remi-test install php-mysql php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml php-pecl-apc php-cli php-pear php-pdo
Step 5: Stopping Apache Service
ApacheandNginxboth services are bind to same port (i.e. 80). So, you must stop turn-offApachein order to useNginx.
# chkconfig --levels 235 httpd off
# /etc/init.d/httpd stop
Step 6: Starting/Stopping Nginx MySQL and PHP-FPM
## Enable Nginx, MySQL and PHP-FPM on Boot ##
# chkconfig --add nginx
# chkconfig --add mysqld
# chkconfig --add php-fpm
## Enable Nginx, MySQL and PHP-FPM on Run Levels ##
# chkconfig --levels 235 nginx on
# chkconfig --levels 235 mysqld on
# chkconfig --levels 235 php-fpm on
## Nginx Startup Commands ##
# /etc/init.d/nginx start
# /etc/init.d/nginx stop
# /etc/init.d/nginx status
## MySQL Startup Commands ##
# /etc/init.d/mysqld start
# /etc/init.d/mysqld stop
# /etc/init.d/mysqld status
## PHP-FPM Startup Commands ##
# /etc/init.d/php-fpm start
# /etc/init.d/php-fpm stop
# /etc/init.d/php-fpm status
Step 7: Configuring Nginx and PHP-FPM
Creating Website Directory
Creating a directory structure for your website under/srv/www/. In my case I usedwww.tecmint.com. This way you can create for your real site.
## public_html directory and logs directory ##
# mkdir -p /srv/www/tecmint/public_html
# mkdir /srv/www/tecmint/logs
# chown -R nginx:nginx /srv/www/tecmint
Creating Website Logs
Creating log directories under/var/log.
## public_html directory and logs directory ##
# mkdir -p /srv/www/tecmint/public_html
# mkdir -p /var/log/nginx/tecmint
# chown -R nginx:nginx /srv/www/tecmint
# chown -R nginx:nginx /var/log/nginx
Configuring Virtual Host Directories
Creating virtual host directoires under/etc/nginx.
# mkdir /etc/nginx/sites-available
# mkdir /etc/nginx/sites-enabled
Add following line of code to/etc/nginx/nginx.conffile at the end, before closing (http block) tag.
## Load virtual host conf files. ##
include /etc/nginx/sites-enabled/*;
For reference see below red line of code, how i added to the file/etc/nginx/nginx.conf.
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
Creating Virtual Host file for Tecmint
Add the following lines of code to/etc/nginx/sites-available/tecmintfile. This is a basic virtual host config file.
server {
server_name tecmint;
access_log /srv/www/tecmint/logs/access.log;
error_log /srv/www/tecmint/logs/error.log;
root /srv/www/tecmint/public_html;
location / {
index index.html index.htm index.php;
}
location ~ .php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /srv/www/tecmint/public_html$fastcgi_script_name;
}
}
Linking Tecmint Virtual Host
Linkingtecmintvirtual host to/etc/nginx/sites-enabled.
# cd /etc/nginx/sites-enabled/
# ln -s /etc/nginx/sites-available/tecmint
Restarting Nginx Service
We need here restart forNginxservice to reflect all the configuration which we have done above.
# /etc/init.d/nginx restart
Adding Virtual Domain to Host File
Add the newly created virtual host domain to your local host file/etc/hosts.
127.0.0.1 localhost.localdomain localhost tecmint
Step 8: Testing Nginx, MySQL, PHP and PHP-FPM
Create a file calledphpinfo.phpunder/srv/www/tecmint/public_html/and add the following lines of code to it. For example (/srv/www/tecmint/public_html/phpinfo.php).
<?php
phpinfo ();
?>
Now access the page with web browser usinghttp://tecmint/phpinfo.phpand verify all versions.
