集群运维自动化工具ansible使用playbook安装mysql
上次介绍了如何使用ansible playbook安装zabbix客户端（http://www.phpstudy.net/article/52158.htm），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 ├── files │ └── mysql.tar.gz ├── handlers ├── meta │ └── main.yml ├── tasks │ ├── copy.yml │ ├── delete.yml │ ├── install.yml │ └── main.yml ├── templates │ ├── install_mysql.sh │ ├── 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。

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，可以从百度云的地址下载（文件大于50M，没办法放到附件或者51下载中心）地址是http://pan.baidu.com/s/1mgG8jY4，然后放到/etc/ansible目录里，下面是压缩包里的内容
