1、修改开机脚本添加文件的权限
[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
