通过mysqltools全自动安装配置mysql复制环境

一、从github下载mysqltools工具包

　　github地址：https://github.com/Neeky/mysqltools

二、环境规划：

主机名　　　　　　　　　　　　　　ip　　　　　　　　　　　　mysql中的角色

master-slave17　　　　　　　　　　10.186.19.17　　　　　　　　master

master-slave18　　　　　　　　　　10.186.19.18　　　　　　　　slave

master-slave19　　　　　　　　　　10.186.19.19　　　　　　　　slave

三、执行自动化安装配置：

ansible-playbook install_master_slaves.yaml

四、在slave上测试配置是否正确：

mysql -uroot -pmtls0352
mysql: [Warning] Using a password on the command line interface can be insecure.
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> show slave status  \G
*************************** . row ***************************
               Slave_IO_State: Waiting for master to send event
                  Master_Host: 10.186.19.17
                  Master_User: rple
                  Master_Port:
                Connect_Retry:
              Master_Log_File: mysql-bin.
          Read_Master_Log_Pos:
               Relay_Log_File: mtls19-relay-bin.
                Relay_Log_Pos:
        Relay_Master_Log_File: mysql-bin.
             Slave_IO_Running: Yes
            Slave_SQL_Running: Yes

结论：

　　mysql复制环境正确的配置好了！

　　整个安装配置的过程用了不到3分钟、通过mysqltools可以大大的节省时间。所以mysqltools是一个提高生产力的好工具！
