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、打开/etc/systemd/system/rc-local.service,在后面加上

[Install]
WantedBy=multi-user.target
Alias=rc-local.service

如果/etc/systemd/system/下没有rc-local.service,可在/lib/systemd/system/下找到这个文件,然后做软链接。

2、创建文件rc.local

sudo vi /etc/rc.local

3、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

4、给rc.local加上权限

sudo chmod +x /etc/rc.local

5、启用服务

sudo systemctl enable rc-local
