通過php修改系統時間

步驟一：建立修改時間腳本 [email protected]:/var/www/userinfo# vim chtime

#!/bin/bash

date -s "$1" 步驟二：給運作該腳本添加sudo權限 [email protected] xxxxxx:/var/www/userinfo# visudo

#

# This file MUST be edited with the 'visudo' command as root.

#

# Please consider adding local content in /etc/sudoers.d/ instead of

# directly modifying this file.

#

# See the man page for details on how to write a sudoers file.

#

Defaults env_reset

Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification

root ALL=(ALL:ALL) ALL www-data ALL=NOPASSWD: /var/www/userinfo/chtime #重點在這裡 步驟三：寫運作該腳本的php [email protected] xxxxxx:/var/www/userinfo# vim ch_time.php

<?php

$new_time = $_GET['new_time'];

$cmd="sudo /var/www/userinfo/chtime \"$new_time\"";

system($cmd); ?> 全部搞定（輸入頁面小case）
