被一個小朋友問到,直接公布答案：

If your MySQL client/server version is a 5.6.x a way to avoid the WARNING message are using the mysql_config_editor tools:

mysql_config_editor set --login-path=local --host=localhost --user=username --password

Then you can use in your shell script:

mysql --login-path=local -e "statement"

instead of:

mysql -u username -p pass -e "statement"

 

使用總結：

mysql_config_editor print --all

mysql_config_editor set --login-path=vip -h10.70.72.22 -uroot -p
mysql_config_editor set --login-path=vip -h10.70.72.12 -uroot -p
mysql_config_editor del --login-path=vip
mysql_config_editor remove vip
mysql_config_editor remove
mysql_config_editor reset
mysql_config_editor set --login-path=local -p
mysql_config_editor set --login-path=vip -h10.70.72.12 -upisp -p
mysql_config_editor set --login-path=vip -h10.70.72.12 -upisp -p
