Mysql集群
上次介绍了如何使用ansible playbook安装zabbix客户端（http://www.bitscn.com/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sockmysql_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

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_installplaybook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

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
