[root@db03-53 ~]# masterha_check_status --conf=/etc/mha/app1.cnf
Got error on conf /etc/mha/app1.cnf: Parameter name master_ip_failover_scrip is invalid!

原因:

在做MHA的VIP时,我先授权再修改文件

解决方法:

[root@db03-53 ~]# ll /etc/mha/app1/master_ip_failover 
-rw-r--r-- 1 root root 2250 Mar 17  2017 /etc/mha/app1/master_ip_failover
[root@db03-53 ~]# vim /etc/mha/app1/master_ip_failover  #修改下面内容
my $vip = '10.0.0.55/24';
my $key = '0';
my $ssh_start_vip = "/sbin/ifconfig eth0:$key $vip";
my $ssh_stop_vip = "/sbin/ifconfig eth0:$key down";
[root@db03-53 ~]# dos2unix /etc/mha/app1/master_ip_failover
[root@db03-53 ~]# chmod +x /etc/mha/app1/master_ip_failover

Got error on conf /etc/mha/app1.cnf: Parameter name master_ip_failover_scrip is invalid!
