ubuntu-18.04 设置开机启动脚本

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。

1、建立rc-local.service文件

1
sudo vi /etc/systemd/system/rc-local.service

2、将下列内容复制进rc-local.service文件

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

1
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

1
sudo chmod +x /etc/rc.local

6、启用服务

1
sudo systemctl enable rc-local

7、启动服务并检查状态

1
2
sudo systemctl start rc-local.service
sudo systemctl status rc-local.service

8、重启并检查test.log文件

1
cat /usr/local/test.log
