ansible批量部署nginx、mysql、tomcat

ansible安装与核心组件详解：http://www.cnblogs.com/Carr/p/7446917.html

ansible初始化配置： 1、修改/etc/ansible/hosts配置文件，在尾部添加内容 vim /etc/ansible/hosts [203] #自定义组名 192.168.0.203 #客户端IP地址 hostname #主机名（前提有DNS域名解析或者修改/etc/hosts文件添加内部解析）

注意：如果不配置/etc/ansible/hosts添加客户端IP，在执行ansible命令时，会报错

通过ansible远程批量安装服务 1、ansible安装（nginx、tomcat、mysql） 在一个IP上，安装一个NGINX，一个TOMCAT,一个MYSQL Nginx 的 80 口反向代理到 tomcat 的 8080口 Mysql里面有db : students , table : profile, 两个字段: name , age Insert 一行 到mysql ,”Teddy”, “12”

2、构建目录结构 mkdir -p /home/cudo/ansible_server/roles/{nginx,mysql,tomcat,db}/{defaults,files,handlers,meta,tasks,templates,vars} ●defaults 默认寻找路径 ●tasks 存放playbooks路径 ●files 存放文件和脚本，copy模块文件搜索路径 ●templates 模版存放路径 ●handlers notify调用部分playbook存放路径 ●vars roles内变量存放路径

3、文件结构 tree /home/cudo/ansible_server/roles/ /home/cudo/ansible_server/roles/ ├── db │ ├── defaults │ ├── files │ │ └── stu.sql #要导入的sql │ ├── handlers │ ├── meta │ ├── tasks │ │ └── main.yml #创建数据库和导入sql │ ├── templates │ └── vars ├── mysql │ ├── defaults │ ├── files │ │ ├── mysql-5.6.27.tar.gz │ │ └── mysql_install.sh #mysql源码安装脚本 │ ├── handlers │ ├── meta │ ├── tasks │ │ └── main.yml #安装mysql │ ├── templates │ └── vars ├── nginx │ ├── defaults │ ├── files │ │ ├── index.html #nginx测试主页面 │ │ ├── install_nginx.sh #nginx安装脚本 │ │ ├── nginx-1.8.0.tar.gz │ │ ├── nginx.conf #nginx主配置文件 │ │ └── test.conf #nginx测试虚拟主机配置文件 │ ├── handlers │ ├── meta │ ├── tasks │ │ └── main.yml #安装nginx │ ├── templates │ └── vars └── tomcat ├── defaults ├── files │ ├── apache-tomcat-7.0.29.tar.gz │ ├── install_java.sh #java安装脚本 │ ├── install_tomcat.sh #tomcat安装脚本 │ ├── jdk1.7.0_79.tar.gz │ ├── server.xml #tomcat配置文件 │ └── start.sh #tomcat服务启动脚本 ├── handlers ├── meta ├── tasks │ └── main.yml #安装java、tomcat ├── templates └── vars ├── web.yml #总调用的文件

4、playbooks & shell /ansible/web.yml

注意：在roles: # - nginx （#）为注释，不安装nginx

/ansible/roles/db/files/stu.sql create table profile(name varchar(20),age tinyint); insert into profile(name,age) values('teddy',12);
