通过php修改系统时间

步骤一：创建修改时间脚本 [email protected]:/var/www/userinfo# vim chtime

#!/bin/bash

date -s "$1" 步骤二：给运行该脚本添加sudo权限 [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 #重点在这里 步骤三：写运行该脚本的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（输入页面小case）
