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
|
1
|
sudo
vi
/etc/systemd/system/rc-local
.service
|
2、将下列内容复制进rc-local.service文件

3、创建文件rc.local
|
1
|
sudo
vi
/etc/rc
.
local

#!/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
|
1
|
sudo
chmod
+x
/etc/rc
.
local
|
6、启用服务
|
1
|
sudo
systemctl
enable
rc-
local
|
7、启动服务并检查状态
|
1
2
|
sudo
systemctl start rc-
local
.service
sudo
systemctl 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
