运维自动化之ansible playbook安装mysql

上次介绍了如何使用ansible playbook安装zabbix客户端（http://dl528888.blog.51cto.com/2382721/1436745），这次介绍一下如何使用playbook安装mysql。

下面是安装mysql的信息：

mysql_basedir: /data/mysql/basedir                    源码目录
mysql_datadir: /data/mysql/datadir                    数据目录
mysql_user: mysql                                     mysql用户
mysql_database_user: root                             数据库用户
mysql_passwd: 'E4yR3WnoluSFTCBAI'                     数据库密码
mysql_port: 3306                                      mysql监听端口
mysql_sock: /data/mysql/datadir/mysql.sock            mysql的sock
mysql_charset: utf8                                   mysql字符集
mysql_collation: utf8_general_ci                      mysql排序方式
mysql_version: Percona-Server-5.5.21-rel25.1.tar.gz   mysql版本

下面是安装mysql的playbook结构

10:24:06 # tree mysql_*
mysql_delete
├── files
├── handlers
├── meta
│   └── main.yml
├── tasks
│   ├── delete.yml
│   └── main.yml
├── templates
└── vars
    └── main.yml
mysql_install

│   ├── my.cnf
│   ├── mysqld
│   └── mysql_security.sh
└── vars
    └── main.yml

12 directories, 15 files

playbook的mysql安装的是

10:32:06 # cat mysql_install.yml 
---
- hosts: "`host`"
  remote_user: "`user`"
  gather_facts: True
  roles:
    - common
    - mysql_install

playbook的mysql协助的是

10:32:44 # cat mysql_delete.yml 
---
- hosts: "`host`"
  remote_user: "`user`"
  gather_facts: True
  roles:
    - mysql_delete

由于在上篇安装zabbix客户端已经介绍了结构，所以现在不介绍了。

1、安装mysql

10:26:00 #  time ansible-playbook mysql_install.yml --extra-vars "host=192.168.240.17 user=root" --private-key=/root/test.pem

2、安装后测试

登陆192.168.240.17的测试机查看mysql安装情况

可以看到已经按照我的要求安装完成，下面在进行删除测试。

3、删除

4、删除后测试

可以看到都删除完成。

如果大家想使用我的例子，可以从github里下载（地址是https://github.com/dl528888/ansible-examples/tree/master/mysql_install），然后放到/etc/ansible目录里，下面是压缩包里的内容
