在Centos7下，rc.local文件，开机默认是不执行的

它是个软链接

[root@data-1-1 ~]# ll /etc/rc.local
lrwxrwxrwx. 1 root root 13 Apr 8 17:11 /etc/rc.local -> rc.d/rc.local

实际文件不具备执行权限,设置开机启动

[root@data-1-1 ~]# ll /etc/rc.d/rc.local
-rw-r--r--. 1 root root 524 Jun 20 09:12 /etc/rc.d/rc.local
[root@data-1-1 ~]# chmod +x /etc/rc.d/rc.local

脚本里加入开机执行命令的脚本

[root@data-1-1 ~]# tail -2 /etc/rc.local
systemctl stop keepalived
/etc/init.d/haproxy stop
[root@data-1-1 ~]# ll /etc/rc.local
lrwxrwxrwx. 1 root root 13 Apr 8 17:11 /etc/rc.local -> rc.d/rc.local
[root@data-1-1 ~]#

之前此机器部署安装了haproxy和Keepalived
重启机器测试。haproxy和Keepalived开机之后被关闭。通过开机执行命令方式

[root@data-1-1 ~]# netstat -lntp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 828/sshd
tcp6 0 0 :::22 :::* LISTEN 828/sshd
[root@data-1-1 ~]# ps -ef |grep keep
root 942 892 0 09:17 pts/0 00:00:00 grep --colour=auto keep
[root@data-1-1 ~]#

其它部分，和本文不相干

查看所有开机启动的服务

[root@linux-node1 ~]# systemctl list-units --type=service

systemctl stop epmd@0.0.0.0.socket
systemctl stop epmd@0.0.0.0
