mha复制检查报错及解决过程
昨天收拾网卡今天收拾mha。mysql
先解释下这个master_ip_failover脚本。这东西是mha4mysql-manager-0.55.tar.gz源码包里给的一个脚本，能够拿来用，可是要作一下修改。sql
作测试的时候尽可能仍是关了防火墙。不然各类找事儿（阻止了3306端口，虽然能够手动开放可是仍是直接关了）app
mha按照配置要求配完以后，abc三台机器。a是master bc是slave ，以后进行连通性检查和复制检查（在master上作）。结果在复制检查的时候报错ssh

MySQL Replication Health is NOT OK!
就从红字开始往下报错。上网查了这个问题，也没个解释。看日志的意思是后者在用的时候不容许前者出现，那就进脚本里找到这个给他屏蔽掉算了。测试
而后从新检查，使用命令是：masterha_check_repl --conf=/etc/mha/app1.cnfspa
就给过了3d
稍微了解了下。貌似master_ip_failover这个脚本里的一些内容是能够不用的，就是说删掉就能够。就像此次这个东西同样日志
