我正在使用的 PHP 程序(会议) 使用 调用脚本sudo
。
我已经允许用户apache
运行该脚本并进行了测试sudo -u apache /usr/local/LConf/lconf_deploy.sh
。
lconf_deploy.sh
当我拨打电话时,系统提示我输入密码/usr/bin/sudo -u icinga /usr/local/LConf/LConfExport.pl -o /etc/icinga/lconf -v
,但拨打此行之前或之后的行时没有问题。
在阅读了大量关于在这种情况下该做什么的资料(在 stackexchange 和互联网的其他地方)之后,我已经禁用requiretty
并使用了NOPASSWD
所有我能想到的影响这种情况的东西。

icinga ALL = NOPASSWD: /usr/local/LConf/LConfExport.pl -o /etc/icinga/lconf -v
sudo
当已经“ ”时,是否可以使用 来切换用户上下文(或诸如此类)sudoing
?
如果没有,我该如何解决这个问题?注意/usr/local/LConf/LConfExport.pl
必须以用户身份运行icinga
。
谢谢,
马特
[根据下面 mdpc 的评论进行了更新]
User_Alias LCONF=apache,icinga
Defaults:LCONF !requiretty
LCONF ALL=(icinga) NOPASSWD: /usr/local/LConf/LconfExport.pl -o /etc/icinga/lconf -v
LCONF ALL= NOPASSWD: /usr/local/LConf/lconf_deploy.sh
执行时sudo -u apache /usr/local/LConf/lconf_deploy.sh.
仍提示输入密码
# cat /usr/local/LConf/lconf_deploy.sh
echo start of script
/usr/bin/sudo -u icinga /usr/local/LConf/LConfExport.pl -o /etc/icinga/lconf -v
/etc/init.d/icinga reload
# sudo -u apache /usr/local/LConf/lconf_deploy.sh
start of script
[sudo] password for apache:

任何帮助都将不胜感激。
答案1
这一行:
apache ALL = NOPASSWD: /usr/bin/sudo -u icinga /usr/local/LConf/LConfExport.pl -o /etc/icinga/lconf -v
不起作用。它将以 apache 身份调用 sudo,这是不对的。
你可能想要的是:
apache ALL=(icinga) NOPASSWD: /usr/local/LConf/LConfExport.pl -o /etc/icinga/lconf -v
答案2
类型
su - apache
然后
/usr/local/LConf/lconf_deploy.sh
如果第一个命令不起作用,请输入:
su - apache -s /bin/bash

<loomsen> there are different ways to solve this, but all of them are ugly and discouraged
<loomsen> mbrownnyc, you could add apache to the icinga group, make that script ug+x and set a sticky bit
<nb-ben> mbrownnyc, you should take a look at suEXEC for php
<koala_man> mbrownnyc: works fine: http://pastebin.com/JhefHzCh
<koala_man> mbrownnyc: I still think you're just confusing your users
<koala_man> mbrownnyc: you add permissions for apache to run lconf_deploy as root, and then test using your icinga user
<koala_man> to run it as apache
解决方案:
# cat /etc/passwd | grep icinga
icinga:x:499:500:icinga:/var/icinga:/bin/false
# cat /etc/passwd | grep apache
apache:x:48:48:Apache:/var/www:/bin/false
