Ubuntu18.04 开机自启动脚本

发布于:2021-11-29 13:23:24

Ubuntu18.04生成rc.local

Ubuntu没有自带其他linux版本自带的rc.local文件的开机自启动方法,所以要自己生成rc.local文件:


    生成rc-local.service文件将一下内容复*鴕c-local…service文件
    sudo gedit /etc/systemd/system/rc-local.service
    将一下内容复*梦募

[Unit]
Description=/etc/rc.local Compatibility
ConditionPathExists=/etc/rc.local #脚本文件位置

[Service]
Type=forking
ExecStart=/etc/rc.local start #配置的脚本文件rc.local为start
TimeoutSec=0
StandardOutput=tty #标准输出
RemainAfterExit=yes
SysVStartPriority=99 #优先级,当有多个开机启动文件时可以设置不同的值

[Install]
WantedBy=multi-user.target

    生成rc.local
    sudo gedit /etc/rc.local
    将一下内容复*募

#!/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

    给rc.local加上权限,启用服务,启动服务并检查状态

sudo chmod +x /etc/rc.local
sudo systemctl enable rc-local
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service

    *舨⒓觳閠est.log文件
    cat /usr/local/test.log

利用rc.local文件配置开机自启动脚本

sudo gedit /etc/rc.local打开脚本文件,然后在exit 0前面加入需要执行的代码即可。
然后再执行下面代码(18.04需要,其他系统可能不需要,可以不执行,*羰砸幌拢


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