• centos7设置rc.local开机执行命令


    背景:自己的服务器放在家里,结果昨天早上跳槽了,12台虚拟机需要全部重启,每个里面都有服务,需要手动起就很麻烦,

    就给每个虚拟机写脚本,开机的时候直接执行。

    一开始把脚本放在/etc/bashrc里面的,但是执行的时候有些特殊

     然后改到rc.local中,具体如下:

    [root@localhost logs]# ll /etc/rc.local
    lrwxrwxrwx. 1 root root 13 May 29 03:16 /etc/rc.local -> rc.d/rc.local
    [root@localhost logs]# ll /etc/rc.d/rc.local
    -rw-r--r--. 1 root root 473 May 12 11:45 /etc/rc.d/rc.local
    [root@localhost logs]# vim /etc/rc.d/rc.local
    [root@localhost logs]# chmod +x /etc/rc.d/rc.local
    [root@localhost logs]# cat /etc/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
    
    
    nohup sh /wgr/logs/start.sh > /dev/null 2&>1  &  

    进行重启,发现日志新增了
