ubuntu-18.04 设置开机启动脚本

作者:Moonce

1、建立 rc-local.service 文件

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

2、将下列内容复制进 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、创建文件 rc.local

sudo vi /etc/rc.local

4、将下列内容复制进 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、给 rc.local 加上权限

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

如果能看到内容，说明设置成功，你就可以通过编辑 rc.local 文件来设置启动脚本了
