我配置了mha+keepalived。当前的master是192.168.98.4，然后执行了init 0模拟主服务器挂，但是发现无法切换。manager.log中报错信息如下：
IN SCRIPT TEST====/bin/systemctl stop keepalived.service==/bin/systemctl start keepalived.service===
Disabling the VIP on old master: 192.168.98.4

我的master_ip_failover中配置：
my $vip = '192.168.98.100'; # Virtual IP
my $key = "1";
my $ssh_start_vip = "/bin/systemctl start keepalived.service";
my $ssh_stop_vip = "/bin/systemctl stop keepalived.service";
请问这里的ssh_start_vip 、ssh_stop_vip 应该如何配置？求指点

错误是无法在原master上执行stop keepalived的脚本，应该如何实现主服务器挂了之后mha自动切换呢？

楼主问题解决了吗？我目前情况跟你一样，求教。
