Ubuntu 20.04 开机执行自定义脚本

家里的服务器重新安装了系统，有些shell脚本需要开机启动，记录一下方法，免得下次又忘了。

0. 请使用root权限执行以下操作

1. 创建rc-local.service文件

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

然后复制service文件配置，不用做任何修改。

[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

2. 创建rc.local文件

vi /etc/rc.local

然后复制以下内容。

#!/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. 

#start script


#end script

echo "added sucessfully!" > /tmp/added_script.log 

exit 0

在“#start script”和“#end script”中编辑自己想要执行的shell命令即可。

3. 赋予可自行权限

chmod +x /etc/rc.local

4. 设置开机启动

systemctl enable rc-local

4. 其他操作

后续就可以使用systemctl进行管理。

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