企业案例：开发mysql多实例启动脚本：
mysql多实例路径为：
[[email protected] ~]# ls -ld /data/3306/
drwxr-xr-x 3 mysql mysql 4096 Oct 9 13:28 /data/3306/1）已知mysql多实例启动命令为：
mysql_safe --default-file=/data/3306/my.cnf &2）停止命令为：
mysqladmin -uroot -poldboy123 -S /data/3306/mysql.sock shutdown
注：其实启动脚本可以更简化，当然作者本人展示的以谨慎的编写来展示脚本
MySQL多实例启动脚本展示：
[[email protected] ~]# cat /data/3306/mysql
#!/bin/sh
#kconfig:2345 13 15
#This is mysql start|stop|restart scripts.

脚本测试：
[[email protected] ~]# /data/3306/mysql start
Mysql start successfully. [ OK ]
[[email protected] ~]# /data/3306/mysql stop
Mysql stop is successfully. [ OK ]
[[email protected] ~]# /data/3306/mysql restart #<==这里因为是在代码中定义了进程不存在就会提示
MyySQL is not run. [FAILED]
[[email protected] ~]# /data/3306/mysql start
Mysql start successfully. [ OK ]
[[email protected] ~]# /data/3306/mysql restart
Mysql stop is successfully. [ OK ]
Mysql start successfully. [ OK ]
Mysql restart is successfully. [ OK ]
