MySQL Replication Health is NOT OK!
解决方案：
1、增加remote_workdir（运行MySQL实例的服务器）的工作目录权限，其中会生成日志文件，将该目录拥有者设为concert
[root@master88 ~]# chown -R concert:concert /mha/
2、添加concert为MySQL同组用户，使其有读取MySQL binary/relay log文件和relay_log.info文件的权限，以及日志目录的写权限
[root@bakmaster ~]# usermod -g mysql concert
再次检查
[concert@mhamanager mha]$ /usr/bin/masterha_check_repl --conf=/etc/appl.cnf
