[root@LVS-RS02 ~] # cat /etc/rc.d/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
说明:如上可知,在CentOS7中, /etc/rc .d /rc . local 文件的权限被降低了,开机的时候执行在自己的脚
本是不能启动的,所有需要添加可执行的权限 [root@LVS-RS02 ~] # ls -l /etc/rc.d/rc.local
-rw-r--r--. 1 root root 473 Nov 7 2016 /etc/rc .d /rc . local
[root@LVS-RS02 ~] # chmod +x /etc/rc.d/rc.local

2、添加一个清空iptables策略的开机脚本

[root@LVS-RS02 ~] # mkdir -p /shells/
[root@LVS-RS02 ~] # vim /shells/clean_iptables.sh
#!/bin/bash /usr/sbin/iptables -F
/usr/sbin/iptables -X
/usr/sbin/iptables -Z
/usr/sbin/setenforce 0
[root@LVS-RS02 ~] # chmod +x /shells/clean_iptables.sh
[root@LVS-RS02 ~] # vim /etc/rc.d/rc.local
# 添加需要开机启动的脚本: /bin/sh /shells/clean_iptables .sh> /dev/null 2>&1
|
通过以上操作,就可以像CentOS6一样添加开机脚本了
