在MySQL多实例中，一个一个启动灰常麻烦，因此写个简单的启动和关闭脚本
启动脚本：start.sh
#!/bin/bash
for port in {3390..3396}
do
(/export/servers/mysql/bin/mysqld_safe --defaults-file=/export/servers/mysql/etc/my$port.cnf ) &
done
关闭脚本：stop.sh
#!/bin/bash
for port in {3390..3396}
do
(/export/servers/mysql/bin/mysqladmin -uroot -p -S /export/data/mysql/tmp/mysql$port.sock shutdown) &
done
