ubuntu-18.04 设置开机启动脚本

参阅下列链接

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

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
