php 通过 sudo 获取 ifconfig eth0 down权限
我已经开了很多帖子了 实在实现不了 希望大神指点下 什么都行 哪怕是资料呢 php sudo 获取权限的就OK 网上的 实在是不靠谱啊

------解决方案--------------------
我是这样: sudo gedit /etc/sudoers 修改后就不用sudo输密码了

------解决方案--------------------
答案就是

1.创建一个文件 例如 pw.txt 里面保存你的root 密码.例如密码为1234
记得文件内容就只要1234

2.php 文件内容
shell_exec('sudo -u root -S ifconfig eth0 down <.>
测试正常关闭网卡
------解决方案--------------------
像你们这般搞法,操作系统的用户保护不是形同虚设了吗?

把你需要的操作放到 shell 文件中,在守候进程中或定时任务中执行
只向前先检查是否存在有启动讯号,如没有则不执行
启动讯号一般可为文件,能被 web 方式的 php 写即可
