MySQL simple script start-stop

For MySQL with multiple instance installations, the process of starting and stopping is relatively complex, and some simple scripts can be defined to simplify routine management.

# environment Variable Script

6.1# determine the current running MySQL instance, with Port partitioning

[[email protected] scripts]$ netstat -lnt | grep 330tcp6       0      0 :::3306                 :::*                    LISTEN

You can see that the current 3306 is running, stop 3306
