Detailed example of deploying Nginx+Apache dynamic and static separation

Introduction to Nginx dynamic and static separation

Nginx has strong static processing capabilities, but insufficient dynamic processing capabilities. Therefore, enterprises often use dynamic and static separation technology to separate PHP from dynamic and static.

• Static pages are handled by Nginx
• Dynamic pages are processed by PHP-FPM module or Apache

In Nginx configuration, different processing methods for static and dynamic pages are implemented through the location configuration segment and regular matching.

Reverse proxy principle

Nginx can not only be used as a Web server, but also has the functions of reverse proxy, load balancing and caching.

Nginx uses the proxy module to proxy the client's request to the upstream server. At this time, the connection between nginx and the upstream server is carried out through the http protocol.

The most important instruction of Nginx when implementing the reverse proxy function is proxy_pass, which can dispatch user requests to the upstream server according to the URI, client parameters or other processing logic.

Configure nginx to achieve dynamic and static separation

In this case, according to the needs of the enterprise, Nginx will be configured to achieve dynamic and static separation. Requests for PHP pages will be forwarded to LAMP for processing, while static pages will be handed over to Nginx for processing to achieve dynamic and static separation.

The architecture is shown in the figure

Configuration steps

1. Set up and debug the backend LAMP environment

①Install Apache service

[root@localhost ~]# yum install httpd httpd-devel -y

②Set the permissions for the http service on the firewall

[root@localhost ~]# firewall-cmd --permanent --zone=public --add-service=http
success
[root@localhost ~]# firewall-cmd --permanent --zone=public --add-service=https
success   
[root@localhost ~]# firewall-cmd --reload 
success
[root@localhost ~]# systemctl start httpd

③Install mariadb

The mariadb database management system is a branch of MySQL, mainly maintained by the open source community and licensed under the GPL. The purpose of mariadb is to be fully compatible with MySQL, including API and command line, so that it can easily become a substitute for MySQL.

[root@localhost ~]# yum install mariadb mariadb-server mariadb-libs mariadb-devel -y
[root@localhost ~]# systemctl start mariadb.service

④MySQL Security Configuration Wizard

[root@localhost ~]# mysql_secure_installation

⑤Install PHP and supporting software

[root@localhost ~]# yum install php -y
[root@localhost ~]# yum install php-mysql -y
[root@localhost ~]# yum install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-snmp php-soap curl curl-devel php-bcmath -y

⑥Change the main page of the website

[root@localhost ~]# cd /var/www/html
[root@localhost html]# vim index.php
<?php
  echo "this is apache test web";
?>

[root@localhost html]# systemctl restart httpd

⑦Access test, enter the URL http://192.168.150.214/index.php

2. Compile and install nginx

①Install support software

[root@localhost ~]# yum install gcc gcc-c++ pcre-devel zlib-devel -y

②Create running users and groups

[root@localhost ~]# useradd -M -s /sbin/nologin nginx

③Compile and install

[root@localhost LNMP-C7]# tar zxvf nginx-1.12.2.tar.gz -C /opt
[root@localhost LNMP-C7]# cd /opt/nginx-1.12.2/
[root@localhost nginx-1.12.2]# ./configure \
> --prefix=/usr/local/nginx \
> --user=nginx \
> --group=nginx \
> --with-http_stub_status_module

[root@localhost nginx-1.12.2]# make && make install
[root@localhost nginx-1.12.2]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin

④Service management control

[root@localhost ~]# vim /etc/init.d/nginx
#!/bin/bash
# chkconfig: -99 20
# description: Ngins Service Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
  $PROG
  ;;
stop)
  kill -s QUIT $(cat $PIDF)
  ;;
restart)
   $0 stop
   $0 start
   ;;
reload
   kill -s HUP $(cat $PIDF)
   ;;
*)
   echo "Usage: $0 {start|stop|restart|reload}"
   exit 1
esac
exit 0

[root@localhost ~]# chmod +x /etc/init.d/nginx
[root@localhost ~]# chkconfig --add nginx
[root@localhost ~]# service nginx start

⑤Start the service

[root@nginx ~]# systemctl stop firewalld.service
[root@nginx ~]# setenforce 0
[root@nginx ~]# service nginx start

⑥Configure nginx to handle dynamic page requests

[root@nginx ~]# vim /usr/local/nginx/conf/nginx.conf
    location ~ \.php$ {
      proxy_pass http://192.168.150.214;
    }

[root@nginx ~]# service nginx restart

⑦Access test
