7.将slave连接到master上 现在创建基本的复制只剩最后一步了：将slave指向master，让它知道从哪里进行复制，为此你需要知道master的4个信息：主机名，主机端口号，主机数据库用户，主机数据库帐号密码，因为创建master的时候已经创建了一个复制用户，因此在slave节点上执行如下指令：
mysql> change master to master_host='localhost',master_port=3310,master_user='repl_user',master_password='111111'; Query OK, 0 rows affected, 2 warnings (0.45 sec) mysql>
mysql> start slave; Query OK, 0 rows affected (0.05 sec) mysql>
8.常见问题排查 执行如上命令后，输出如下信息： 2014-03-26 23:11:23 6916 [ERROR] Slave I/O: error connecting to master 'repl_user@localhost:3310' - retry-time: 60 retries: 1, Error_code: 1045 这个说明slave和master之间的链接没有建立成功，这个时候多半是添加了新用户repl_user后，没有生效导致 在master上执行flush privileges;来将新建的用户及权限生效
