special character issue.

[eslee1980]

An error occurs if the mha account password contains special characters (ex:!,^,*... ).

Any solution to this problem?

Due to password policy, passwords must contain special characters.

Please help me.

[root@rhel2 masterha]# cat /etc/masterha-default.cnf
[server default]
user=mha
password=root123! <--

ssh_user=root
ssh_port=22

repl_user=repl
password=root123! <--

It is better to execute FLUSH NO_WRITE_TO_BINLOG TABLES on the master before switching. Is it ok to execute on rhel2(192.168.2.129:3306)? (YES/no): yes
