Ubuntu18.04及以上开机自启动脚本设置方法_ubuntu 1804 kaijiziqid daisudo

一、问题

ubuntu-18.04及以上系统取消了rc.local自启动功能，因此不能像ubuntu16一样通过编辑rc.local来设置开机启动脚本，通过下列简单设置后，可以使rc.local重新发挥作用。

二、方法

1、建立rc-local.service文件

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

2、输入如下内容

[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

sudo vim /etc/rc.local

4、输入如下内容

#!/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.
echo "成功启动CAN驱动配置" > /usr/local/test.log
 
sudo modprobe can
sudo modprobe can_raw
sudo modprobe mttcan
 
sudo ip link set can0 type can bitrate 500000
sudo ip link set up can0
 
exit 0

5、添加rc.local可执行权限

sudo chmod +x /etc/rc.local

6、启动服务

sudo systemctl enable rc-local

7、启动服务查看启动状态

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

8、重启，若在/usr/local下能够看到 test.log文件说明自启动已经成功了！
