在Ubuntu 18.04 中设置开机自动执行脚本

Ubuntu18.04 不能像16.04 那样可以直接使用 /etc/rc.local 文件，需要设置

1.建立 rc-local.service 文件

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

2.复制下列内容到 rc-local.service 文件中

[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.创建文件 rc.local

sudo vim /etc/rc.local

4.复制下列内容到 rc.local 文件中

#!/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 "测试脚本执行成功" > /usr/local/test.log
exit 0

5.给 rc.local 加上权限，启用服务

sudo chmod 755 /etc/rc.local
sudo systemctl enable rc-local

6.启动服务并检查状态

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

7.重启后检查test.log文件是否已经存在
