ubuntu-18.04不能像ubuntu14一样通过编辑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。
- 建立 rc.local.service 文件
sudo vim /etc/systemd/system/rc-local.service
- 将下面内容复制到 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
- 创建文件 rc.local
sudo vim /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.将下列内容复制进rc.local文件
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 文件是否存在，如果存在说明开机脚本设定成功
cat /usr/local/test.log
