centos7設置rc.local開機執行命令
阿新 • • 發佈：2019-03-02
roo chmod tst pmd nec servers 通過 不執行 systemctl
在Centos7下，rc.local文件，開機默認是不執行的
它是個軟鏈接
[root@data-1-1 ~]# ll /etc/rc.local lrwxrwxrwx. 1 root root 13 Apr 8 17:11 /etc/rc.local -> rc.d/rc.local
實際文件不具備執行權限,設置開機啟動
[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
腳本裏加入開機執行命令的腳本
[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 ~]#
之前此機器部署安裝了haproxy和Keepalived
重啟機器測試。haproxy和Keepalived開機之後被關閉。通過開機執行命令方式
[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，和本文不相幹
查看所有開機啟動的服務
[root@linux-node1 ~]# systemctl list-units --type=service 禁用epmd systemctl stop [email protected] systemctl stop [email protected]
