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
