ubuntu-18.04 設置開機啟動腳本
參閱下列鏈接
ubuntu-18.04不能像ubuntu14一樣通過編輯rc.local來設置開機啟動腳本，通過下列簡單設置后，可以使rc.local重新發揮作用。
1、建立rc-local.service文件
|
1
|
sudo
vi
/etc/systemd/system/rc-local
.service
|
2、將下列內容復制進rc-local.service文件

3、創建文件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
"看到這行字，說明添加自啟動腳本成功。"

/usr/local/test
.log
exit
0

5、給rc.local加上權限
|
1
|
sudo
chmod
+x
/etc/rc
.
local
|
6、啟用服務
|
1
|
sudo
systemctl
enable
rc-
local
|
7、啟動服務並檢查狀態
|
1
2
|
sudo
systemctl start rc-
local
.service
sudo
systemctl status rc-
local
.service
|
8、重啟並檢查test.log文件
|
1
|
cat
/usr/local/test
.log
|
如果能看到內容，說明設置成功，你就可以通過編輯rc.local文件來設置啟動腳本了
