Ansible-playbook部署并发布上线电商项目（LNMP环境）

环境准备

服务器系统	Centos6.8
内存	1G
CPU	2核
IP地址	10.0.0.20
服务	MysqL数据库

服务器系统	Centos6.8
内存	1G
CPU	2核
IP地址	10.0.0.21
服务	Ansible管理主机

服务器系统	Centos6.8
内存	1G
CPU	2核
IP地址	10.0.0.22
服务	LNMP环境的搭建并上线电商项目

在21Ansible管理主机上操作，我们需要准备Nginx源码包和电商包

创建目录
mkdir lnmp
进入目录
cd lnmp/

解压上传到服务器上的nginx包
tar zxf nginx-1.12.0.tar.gz 
进入解压过后的nginx目录
cd nginx-1.12.0/conf/
拷贝Nginx配置文件至lnmp目录下
cp nginx.conf ../../
cd ../../
删除nginx目录
rm -rf nginx-1.12.0
编写php测试页面
vim index.php
<?php
phpinfo();
?>
将php测试页面文件改名
mv index.php info.php

vim /etc/ansible/hosts 

编辑nginx配置文件
vim /root/lnmp/nginx.conf 

编辑yml文件
vim lnmp.yml

检查yml文件的语法是否正确
ansible-playbook --syntax-check lnmp.yml 

执行ansible剧本命令
ansible-playbook lnmp.yml
