问题：配置MHA时候，测试主从复制
第一次：masterha_check_repl -conf=/etc/masterha/app1.cnf

MySQL Replication Health is NOT OK!

解决：将三台机器mysql的my.cnf的default-character-set=utf8注销掉

第二次：masterha_check_repl -conf=/etc/masterha/app1.cnf

显示没有那个文件目录

解决：创建文件manager.log

[root@manager ~]# mkdir -p  /var/log/masterha/app1/
[root@manager ~]# touch /var/log/masterha/app1/manager.log

第三次：masterha_check_repl -conf=/etc/masterha/app1.cnf
再次报错

方法：查询之前的/etc/masterha/app1.cnf

再次masterha_check_repl -conf=/etc/masterha/app1.cnf 成功！！
