添加开机自启动脚本-Ubuntu18.04

Hello World 2022-01-22 AM 106℃ 0条

操作系统版本:Ubuntu 18.04
网上查阅了很多资料,发现乌班图并没有/etc/rc.local这个文件,结合自己踩的坑,记录一下在Ubuntu18.04添加开机自启动脚本过程,Ubuntu其他版本同理。

1、建立rc-local.service文件

sudo vi /etc/systemd/system/rc-local.service

2、将下列内容复制到刚创立的rc-local.service文件

[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local
 
[Service]
Type=forking
ExecStart=/etc/rc.local start
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
SysVStartPriority=99
 
[Install]
WantedBy=multi-user.target

3、创建rc.local文件

sudo vi /etc/rc.local

4、将下列内容复制到刚创立的rc.local文件

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo "看到这行字,说明添加自启动脚本成功。" > /usr/local/test.log
exit 0

5、为rc.local加可执行权限

sudo chmod +x /etc/rc.local

6、启用服务

sudo systemctl enable rc-local

7、启动服务并检查状态

sudo systemctl start rc-local.service
sudo systemctl status rc-local.service

8、重启并检查test.log文件

cat /usr/local/test.log

如果可以看到内容,说明设置成功,我们就可以通过编辑/etc/rc.local文件来设置启动脚本了。注意要写在exit 0 的上方。
