Centos7设置开机自动运行脚本

1. Centos7设置开机自动运行脚本

[root@bigdata001 ~]# 
[root@bigdata001 ~]# cat restart.sh 

nohup echo `date` >> /root/restart.log 2>&1 &

[root@bigdata001 ~]# 

添加执行权限给restart.sh

[root@bigdata001 ~]#
[root@bigdata001 ~]# chmod +x restart.sh
[root@bigdata001 ~]#

添加restart.sh到开机自动执行

[root@bigdata001 ~]# 
[root@bigdata001 ~]# 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

/root/restart.sh
[root@bigdata001 ~]# 

添加执行权限给rc.local

[root@bigdata001 ~]#
[root@bigdata001 ~]# chmod +x /etc/rc.d/rc.local
[root@bigdata001 ~]#

现在reboot重启服务器，查看/root/restart.log日志如下：

[root@bigdata001 ~]# 
[root@bigdata001 ~]# cat date.log
