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

sudovi/etc/systemd/system/rc-local.service

2、将下列内容复制进rc-local.service文件

[Unit]

Description=/etc/rc.localCompatibility

ConditionPathExists=/etc/rc.local

[Service]

Type=forking

ExecStart=/etc/rc.localstart

TimeoutSec=0

StandardOutput=tty

RemainAfterExit=yes

SysVStartPriority=99

[Install]

WantedBy=multi-user.target

3、创建文件rc.local  

1

sudovi/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

exit0

5、给rc.local加上权限

1

sudochmod+x/etc/rc.local

6、启用服务

1

sudosystemctlenablerc-local

7、启动服务并检查状态

1

2

sudosystemctl start rc-local.service

sudosystemctl status rc-local.service

8、重启并检查test.log文件

1

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
