centos7下的/etc/rc.local自启动程序

在centos6中有一个/etc/rc.local的启动文件，只要把需要经常启动的程序添加到此文件下并执行source /etc/rc.local就可以实现开机启动了。

在centos7中不知道也是如此操作吗？

    [root@centos ~]# cat /etc/rc.local
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure      
# that this script will be executed during boot.

touch /var/lock/subsys/local

# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure ，看到这句话，就会发现需要给文件/etc/rc.local添加执行权限就可以实现程序自启动。
