Nginx实现服务器动静分离

Nginx可以实现动态和静态分离的操作，一般情况下用于Nginx分离PHP或者Nginx分离js脚本，通过请求的类型转发请求到应用服务器；
本篇文章讲解使用Nginx配置PHP分离文件。

PHP FastCGI配置分离的Nginx配置文件
PHP服务器IP：10.0.0.99:9000
Nginx服务器IP：10.0.0.113
测试网站使用之前配置的blog服务器

  location ~ ^/.+\.php {
        fastcgi_index            index.php;
        fastcgi_split_path_info  ^(.+\.php)(/.*)$;
        fastcgi_param            SCRIPT_FILENAME $request_filename;
        fastcgi_param            PATH_INFO $fastcgi_path_info;
        fastcgi_param            PATH_TRANSLATED $document_root$fastcgi_path_info;
        include                  fastcgi_params;
        fastcgi_pass             10.0.0.99:9000;
    }

PHP独立服务器安装PHP7.3

  #安装运行环境
  yum -y install gcc gcc-c++
  #安装第三方软件源
  yum -y install epel-release
  #安装软件包
  yum install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
  yum install -y http://rpms.remirepo.net/enterprise/remi-release-7.rpm
  #安装包管理器组件
  yum -y install yum-utils
  #启用php7.3源
  yum-config-manager --enable remi-php73
  #安装PHP7需要的组件
  yum -y install php php-mcrypt php-devel php-cli php-gd php-pear php-curl php-fpm php-mysql php-ldap php-zip php-fileinfo

修改Nginx的配置文件

  upstream php-fastcgi {
            server 127.0.0.1:9000;

重启Nginx服务后打开浏览器查看网站能不能正常打开

  systemctl restart nginx

浏览器打开网站
