##在剧本的当前目录中，需要准备需要的文件index.php
nginx.repo
default.conf.j2www.conf
php.ini.j2

###  index.php<?php
phpinfo();
?>

#  nginx.repo[nginx]
name=nginx repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

group = php
listen = 192.168.242.69:9000
listen.allowed_clients = 192.168.242.67

##  php.ini.j2  配置文件模板###修改几行1097行
mysqli.default_socket = {{mysql_dir}}877行
date.timezone = {{timezone}}

##templates目录  中存放  nginx 的  j2  的配置文件模板##修改几行listen       {{http_port}};
server_name  {{http_hostname}};root   {{root_dir}};location ~ \.php$ {root           {{root_dir}};fastcgi_pass   {{http_remote}};fastcgi_index  index.php;fastcgi_param  SCRIPT_FILENAME  {{root_dir}}$fastcgi_script_name;include        fastcgi_params;}
