ubuntu高版本如何设置开机启动脚本

ubuntu-18.04不能像ubuntu14一样通过编辑rc.local来设置开机启动脚本

可以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
