ubuntu14 設定開機啟動指令碼

什麼是rc.local指令碼

c.local指令碼是一個ubuntu開機後會自動執行的指令碼，我們可以在該指令碼內新增命令列指令。該指令碼位於/etc/路徑下，需要root許可權才能修改。該指令碼具體格式如下：

#!/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.
 
exit 0

如何給ubuntu新增一個開機啟動指令碼

1,新建個指令碼檔案new_service.sh

#!/bin/bash
# command content
 
exit 0

2,設定許可權

sudo chmod 755 new_service.sh

3,把指令碼放置到啟動目錄下

sudo mv new_service.sh /etc/init.d/

cd /etc/init.d/
sudo update-rc.d new_service.sh defaults 90

sudo update-rc.d -f new_service.sh remove
