The LEMP stands for Linux, Nginx, MySQL and PHP. Apart from LAMP Nginx server with PHP-FPM pagespeed module and memcached is a highly efficient and fast webserver setup, with this setup your website load time will be pretty fast. This setup reduces the server response time to a greater extent and is apt for faster websites made of CMSs like WordPress, Joomla, Magento etc. You can definitely reduce server cost with this setup because you can host your website on a small cloud VPS instead of a big dedicated server without losing any performance or website load time
For this setup, we need to disable SELinux (Security Enhanced Linux) first to avoid bottlenecks. For doing so, just edit the SELinux config file (/etc/selinux/config) as given below.
echo "SELINUX=disabled" > /etc/selinux/config echo "SELINUXTYPE=targeted" >> /etc/selinux/config
Now we have to modify the SELinux mode with,
setenforce 0
To get or activate the current mode,
getenforce
Now before begining the install, let’s just clear the yum repo cache with the command:
yum clean all
Now we can begin the installation. First we need to setup the ‘epel’, ‘remi’ and ‘nginx’ repos to get the packages. Follow the steps given below for the purpose.
To seup the epel repo use ;
rpm -Uhv http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6- 8.noarch.rpm
To setup remi repo use;
rpm -Uhv http://rpms.famillecollet.com/enterprise/6/remi/x86_64/remi- release-6.5-1.el6.remi.noarch. rpm
We’ll have to setup nginx repo manually. For this we need to create a ‘nginx.repo’ file in the yum repo location ‘/etc/yum.repos.d’ and add the directives ‘name’, ‘baseurl’ etc. Use the commands below.
echo "[nginx]" > /etc/yum.repos.d/nginx.repo echo "name=nginx repo" >> /etc/yum.repos.d/nginx.repo echo "baseurl=http://nginx.org/packages/centos/\$\releasever/\$\ basearch/" >> /etc/yum.repos.d/nginx.repo echo "gpgcheck=0" >> /etc/yum.repos.d/nginx.repo echo "enabled=1" >> /etc/yum.repos.d/nginx.repo
Now that the repos are added, we can install all the packages and its dependencies simply with yum.
yum install -y unzip git gcc-c++ pcre-dev pcre-devel zlib-devel make php-apc php-bcmath php-curl php-dba php-dom php-fileinfo php-gd php-pecl-igbinary php-intl php-ioncube-loader php-json php-mbstring php-mcrypt php-memcache php-pecl-memcached php-mysql php-pdo php-pdo-mysql php-sqlite3 php-phar php-posix php-pspell php-recode php-soap php-tidy php-wddx php-xmlreader perl wget php-fpm memcached GeoIP GeoIP-devel perl-ExtUtils-Embed gd gd-devel libxml2 libxml2-devel libxslt-devel libxslt xslt pcre-devel openssl-devel nginx mysql-server
After this, we need to enable the services (mysqld, nginx, php-fpm, memcached) in chkconfig for auto start after reboot.
chkconfig mysqld on chkconfig nginx on chkconfig php-fpm on chkconfig memcached on
Memcached is installed for caching the static contents like images etc.
Now we can move onto installing the pagespeed module for nginx. Follow these steps for the same:
cd /root wget https://github.com/pagespeed/ngx_pagespeed/archive/release-1 .8.31.4-beta.zip unzip release-1.8.31.4-beta.zip cd ngx_pagespeed-release-1.8.31.4 -beta/ wget https://dl.google.com/dl/page- speed/psol/1.8.31.4.tar.gz tar -xzvf 1.8.31.4.tar.gz cd /root wget http://nginx.org/download/ngin x-1.6.0.tar.gz tar -xvzf nginx-1.6.0.tar.gz cd nginx-1.6.0/
The above given steps downloads the pagespeed module archives and exctrats it in the installaion direcory. Before installing the package, delete all the already compiled object files with the command given below.
make clean
This to clean up all the failed make, if any. After cleaning up, we can configure package with the necessary extensions, data directories etc. Here is my configuration.
./configure --add-module=$HOME/ngx_pagespeed-release-1.8.31.4-beta --with-debug --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.c onf --error-log-path=/var/log/ngin x/error.log --http-log-path=/var/log/nginx /access.log --http-client-body-temp-path=/ var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/li b/nginx/tmp/proxy --http-fastcgi-temp-path=/var/ lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/li b/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib /nginx/tmp/scgi --pid-path=/var/run/nginx.pid --lock-path=/var/lock/subsys/n ginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_realip_module --with-http_addition_module --with-http_xslt_module --with-http_image_filter_modul e --with-http_geoip_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gzip_static_module --with-http_random_index_modul e --with-http_secure_link_module --with-http_degradation_module --with-http_stub_status_module --with-http_perl_module --with-mail --with-mail_ssl_module --with-debug--with-pcre --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic' --with-ld-opt=-Wl,-E
After configuration, create ‘makefile’ with,
make
Now, install the package with the created ‘makefile’ using the command,
make install
nginx –with-http_ssl_module this module will enable SSL module with nginx
nginx –with-pcre This library is necessary for regular expressions support in location directive and nginx rewrite module
Installation is now complete. Now we will have to create Nginx core and tmp directories.
mkdir -p /var/lib/nginx/tmp/client_body mkdir -p /var/log/nginx/cores
Now we will have to start the services manually.
service iptables restart service mysqld restart service nginx restart service php-fpm restart service memcached restart
One last thing to do is to set password for the MySQL root user. You can use the command below.
mysqladmin -u root password <desired_password>
With this, Nginx with PHP-FPM and pagespeed installation is complete. We’ll now move on to configuration of Nginx and wesite configuration with Nginx.
Below given is a sample of the Nginx configuration file (/etc/nginx/nginx.conf)

In the above given Nginx config file, there is an ‘include’ directive with which we can include other files into the configuration. In our setup we are creating separate conf files for each website to specify its VirtualHost.
Here is a sample of website conf file included in the Nginx configuration. The conf file shown below is ‘/etc/nginx/conf.d/domain.conf
server {
listen 11.11.11.11:80;
server_name www.iserversupport.com
access_log /var/log/nginx/iserversupport.com.acce
Now please upload your contents to /home/user/public_html/
With this, you are set to host websites with Nginx with PHP-FPM, MySQL, PageSpeed and Memcached setup. Enjoy your time :)
install nginx php-fpm mysql
