1，创建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,重启前往/usr/local/ 查看测试的test.log的文件是否存在

reboot
