运维自动化之ansible playbook安装mysql

技术小胖子 2017-11-14 16:24:00 浏览1762

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
