Nginx ngx_pagespeed

Ngx_pagespeed is an extension module of Nginx. Its main function is to optimize front-end pages on the server side. For front-end designers, the process of optimizing css, js and images can be omitted. NGx_pagespeed can hardly improve the load capacity of nginx itself, and even increase the load of the system due to server side optimization; However, from the perspective of reducing the number of customer requests, it is worthwhile to sacrifice some server performance.

The main functions of the ngx_pagespeed module are as follows:

• Image optimization: stripping metadata, dynamic adjustment, and recompression
• CSS and JavaScript compression, merging, cascading, inline
• Small resource inline
• Postpone image and JavaScript loading
• Rewrite HTML, compress spaces, remove comments, etc
• Increase cache cycle

This installation tutorial is for CentOS7.2 64 bit Practical.

Dependencies for installing or upgrading ngx_pagespeed for new or lower version systems:

RedHat, CentOS, or Fedora

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

Ubuntu or Debian

 sudo apt-get install build-essential zlib1g-dev libpcre3 libpcre3-dev unzip

If it has already been installed, the dependency needs to be updated (gcc ≥ 4.8 or clang ≥ 3.3 is required)

Because I want to be stable, the software required for the next configuration is the latest stable version before November 12.

Download various software

Install ngx_pagespeed

Get arguments

 nginx -V

 --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-openssl=../ openssl-1.0.2j --with-pcre=../ pcre-8.39 --with-pcre-jit --with-ld-opt=-ljemalloc

Reorganize required software

Directory location of openssl:

 /usr/local/src/openssl-1.0.2j

Directory location of pcre:

 /usr/local/src/pcre-8.39

Location directory of ngx_pagespeed:

 /usr/local/src/ngx_pagespeed

Organize new arguments

Reorganize the configuration arguments according to the obtained configuration arguments and the location of the above software

Then add --add-module=/usr/local/src/ngx_pagespeed

The sorted results are:

 --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-openssl=/usr/local/src/openssl-1.0.2j --with-pcre=/usr/local/src/pcre-8.39 --with-pcre-jit --with-ld-o pt=-ljemalloc --add-module=/usr/local/src/ngx_pagespeed

Start Installation

Here you choose to reinstall and compile

 cd /usr/local/src/nginx-1.10.2 ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-openssl=/usr/local/src/openssl-1.0.2j --with-pcre=/usr/local/src/pcre-8.39 --with-pcre-jit  --with-ld-opt=-ljemalloc --add-module=/usr/local/src/ngx_pagespeed make && make install

Check whether the installation is normal

 nginx -V nginx version: nginx/1.10.2 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-4) (GCC) built with OpenSSL 1.0.2j  26 Sep 2016 TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --user=www --group=www --with-http_stub_status_module --with-http_v2_module --with-http_ssl_module --with-ipv6 --with-http_gzip_static_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-openssl=/usr/local/src/openssl-1.0.2j --with-pcre=/usr/local/src/pcre-8.39 --with -pcre-jit --with-ld-opt=-ljemalloc --add-module=/usr/local/src/ngx_pagespeed

 nginx -t nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

Ok, so far the installation of ngx_pagespeed has been completed. Let's talk about how to configure and use it in the next chapter.
