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
