vi etc init.d mysql_vim /etc/init.d/mysqld

/etc/init.d 是一般开机的启动服务存放在这个目录下

/etc/rc.d启动的配置文件和脚本

/etc/init.d & /etc/rc.d/init.d是同一个目录，内容相同

实现机制，其实/etc/init.d是一个符号链接文件，链接指向/etc/rc.d/init.d

你运行以下命令可以看出来

[root@localhost ~]#ls -ld /etc/init.d

lrwxrwxrwx. 1 root root 11 Oct 2 12:15 /etc/init.d -> rc.d/init.d

建立方法是：ln -s /etc/rc.d/init.d /etc/init.d

[root@localhost ]# vim /etc/init.d/mysqld
