Tag: CentOS 6.6

This article will show you the steps to install Nginx and ngx_pagespeed module on Linux CentOS 6 virtual private server (VPS). By using ngx_pagespeed, the speed of your website will be faster without installing any additional applications such as wordpress plugin and so on. This is because ngx_pagespeed have some Nginx module which rewrites your webpages to make them faster. Below steps has been tested on CentOS 6.5 and CentOS 6.6.

1. Install nginx PageSpeed dependencies :

yum install gcc-c++ pcre-devel pcre-devel zlib-devel make unzip openssl-devel

2. Download and install ngx_pagespeed and PSOL (PageSpeed Optimization Libraries) source code :

mkdir -p /etc/nginx/modules
cd /etc/nginx/modules
wget https://github.com/pagespeed/ngx_pagespeed/archive/release-1.9.32.2-beta.zip
unzip release-1.9.32.2-beta.zip
cd ngx_pagespeed-release-1.9.32.2-beta/
wget https://dl.google.com/dl/page-speed/psol/1.9.32.2.tar.gz
tar xzvf 1.9.32.2.tar.gz

3. Download NGINX :

cd /etc/nginx/
wget http://nginx.org/download/nginx-1.6.2.tar.gz
tar xzvf nginx-1.6.2.tar.gz
cd nginx-1.6.2/

4. Compile and prepare environment for NGINX with ngx_pagespeed module support :

./configure --add-module=/etc/nginx/modules/ngx_pagespeed-release-1.9.32.2-beta --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-file-aio --with-http_spdy_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module --with-mail --with-mail_ssl_module --with-cc-opt='-O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic'

At the end of installation, you will get the following message :

  nginx path prefix: "/etc/nginx"
  nginx binary file: "/usr/sbin/nginx"
  nginx configuration prefix: "/etc/nginx"
  nginx configuration file: "/etc/nginx/nginx.conf"
  nginx pid file: "/var/run/nginx.pid"
  nginx error log file: "/var/log/nginx/error.log"
  nginx http access log file: "/var/log/nginx/access.log"
  nginx http client request body temporary files: "/var/cache/nginx/client_temp"
  nginx http proxy temporary files: "/var/cache/nginx/proxy_temp"
  nginx http fastcgi temporary files: "/var/cache/nginx/fastcgi_temp"
  nginx http uwsgi temporary files: "/var/cache/nginx/uwsgi_temp"
  nginx http scgi temporary files: "/var/cache/nginx/scgi_temp"

Note : Keep this information as you will need it if you plan to uninstall the NGINX.

Building the NGINX with ngx_pagespeed :

make

Install NGINX with ngx_pagespeed to the system :

make install

5. Create a Cache directory which will be written by Nginx.

mkdir /var/ngx_pagespeed_cache
chown nginx:nginx /var/ngx_pagespeed_cache

6. Configure NGINX (nginx.conf) and turn on pagespeed module :

..
..
pagespeed on;
pagespeed FileCachePath /var/ngx_pagespeed_cache;

# enable CoreFilters
pagespeed RewriteLevel CoreFilters;

# enable additional filter(s) selectively
pagespeed EnableFilters collapse_whitespace;
pagespeed EnableFilters lazyload_images;
pagespeed EnableFilters insert_dns_prefetch;
pagespeed EnableFilters prioritize_critical_css;
pagespeed EnableFilters collapse_whitespace;
..
..

7. Create an init script for Nginx.

vi /etc/init.d/nginx

#!/bin/sh
#
# nginx        Startup script for nginx
#
# chkconfig: - 85 15
# processname: nginx
# config: /etc/nginx/nginx.conf
# config: /etc/sysconfig/nginx
# pidfile: /var/run/nginx.pid
# description: nginx is an HTTP and reverse proxy server
#

    RETVAL=$?
    echo
}

upgrade() {
    oldbinpidfile=${pidfile}.oldbin

    configtest -q || return
    echo -n $"Starting new master $prog: "
    killproc -p ${pidfile} ${prog} -USR2
    echo

    for i in `/usr/bin/seq $UPGRADEWAITLOOPS`; do

configtest() {
    if [ "$#" -ne 0 ] ; then
        case "$1" in
            -q)
                FLAG=$1
                ;;
            *)
                ;;

        RETVAL=2
esac

exit $RETVAL

chmod 0755 /etc/init.d/nginx
chown root:root /etc/init.d/nginx

8. Start nginx and make it autostart at boot :

service nginx start
chkconfig nginx on

9. Check NGINX version and installed modules :

$ nginx -V
nginx version: nginx/1.6.2
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC)
TLS SNI support enabled
configure arguments: --add-module=/etc/nginx/modules/ngx_pagespeed-release-1.9.32.2-beta --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-file-aio --with-http_spdy_module --without-mail_pop3_module --without-mail_imap_module --without-mail_smtp_module --with-mail --with-mail_ssl_module --with-cc-opt='-O2 -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic'

10. Testing the pagespeed module:

curl -I http://www.ehowstuff.local

You should see X-Page-Speed version in the headers:

HTTP/1.1 200 OK
Server: nginx
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
Vary: Accept-Encoding
X-Pingback: http://www.ehowstuff.local/xmlrpc.php
Date: Thu, 01 Jan 2015 06:41:14 GMT
X-Page-Speed: 1.9.32.2-4321
Cache-Control: max-age=0, no-cache
