O NGINX ( Engine X ) é sem dúvida um dos web servers mais optimizados em termos de velocidade de entrega de conteúdo. O módulo NGX PageSpeed dá um gás ainda maior na entrega de conteúdo no web server. Neste artigo irei exemplificar como fazer a instalação do NGX PageSpeed no NGINX.
Principais funcionalidades
HTTPS support with URL control.
Image optimization: stripping meta-data, dynamic resizing, recompression.
CSS and JavaScript minification, concatenation, inlining, and outlining.
Small resource inlining.
Deferring image and JavaScript loading.
HTML rewriting.
Cache lifetime extension.
Allows configuring for multiple servers and many others.
Instalação
Estarei utilizando o Debian 9 para instalar o NGX PageSpeed rodando com um NGIX 1.10.1
Vamos a instalação:
1) Execute o comando via CLI
$ sudo apt-get install build-essential zlib1g-dev libpcre3 libpcre3-dev unzip 2) Criando o diretório para download dos pacotes. Começaremos pelo NGINX
$ mkdir -p ~/make_nginx $ cd ~/make_nginx $ wget -c https://nginx.org/download/nginx-1.13.2.tar.gz $ tar -xzvf nginx-1.13.2.tar.gz 3) Baixando o PageSpeed
$ wget -c https://github.com/pagespeed/ngx_pagespeed/archive/v1.12.34.2-stable.zip $ unzip v1.12.34.2-stable.zip 4) Mova o PageSpeed para o diretório do NGINX.
$ cd ngx_pagespeed-1.12.34.2-stable/ $ wget -c https://dl.google.com/dl/page-speed/psol/1.12.34.2-x64.tar.gz $ tar -xvzf 1.12.34.2-x64.tar.gz 5) Configurando e compilando o NgINX e o PageSpeed
$ cd ~/make_nginx/nginx-1.13.2
$ ./configure --add-module=$HOME/nginx/ngx_pagespeed-1.12.34.2-stable/ ${PS_NGX_EXTRA_FLAGS}
$ make $ sudo make install
$ sudo ln -s /usr/local/nginx/conf/ /etc/nginx $ sudo ln -s /usr/local/nginx/sbin/nginx /usr/sbin/nginx
6) Criando o arquivo do Unit para o SystemD
$ sudo vi /lib/systemd/system/nginx.service
[Unit] Description=The NGINX HTTP and reverse proxy server After=syslog.target network.target remote-fs.target nss-lookup.target [Service] Type=forking PIDFile=/var/run/nginx.pid ExecStartPre=/usr/sbin/nginx -t ExecStart=/usr/sbin/nginx ExecReload=/bin/kill -s HUP $MAINPID ExecStop=/bin/kill -s QUIT $MAINPID PrivateTmp=true [Install] WantedBy=multi-user.target 7) Iniciando o NGINX
$ sudo systemctl start nginx $ sudo systemctl enable nginx 8) Configurando o módulo PageSpeed
$ sudo mkdir -p /var/ngx_pagespeed_cache $ sudo chown -R nobody:nogroup /var/ngx_pagespeed_cache
Para habilitar o módulo do PageSpeed no NGINX abra o arquivo de configuração do NGIX em
$ sudo vi /etc/nginx/nginx.conf
Adicione as linhas abaixo:
# Pagespeed main settings
pagespeed on;
pagespeed FileCachePath /var/ngx_pagespeed_cache;
# Ensure requests for pagespeed optimized resources go to the pagespeed
# handler and no extraneous headers get set.
location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
location ~ "^/ngx_pagespeed_static/" { }
location ~ "^/ngx_pagespeed_beacon" { }

Verificando configuração
$ sudo 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 Testando o PageSpeed O módulo do PageSpeed adiciona uma flag no header do pacote TCP informando que ele está presente. Para saber execute:
$ curl -I -p http://localhostPara saber mais sobre o projeto do PageSpeed acess: https://github.com/pagespeed/ngx_pagespeed
