php - Calling ejabberdctl from PHP

Question

I am working on a php social network that requires us to create XMPP accounts for all new members. I have a working Ejabberd server running with mod_admin_extra all working fine.

I am trying to call ejabberdctl from a php file like so:

exec('sudo /home/user/ejabberd-2.1.2/bin/ejabberdctl register test server pass 2>&1');

but i get the following error :

Failed RPC connection to the node ejabberd@localhost: nodedown

Although the same command works from the command line.

I have also added the following to /etc/sudoers :

www-data ALL= NOPASSWD: /home/webuser/ejabberd-2.1.2/bin/ejabberdctl

So what gives?

Answer 1

使用phpseclib，一个纯 PHP SSH 实现，你可能会有更好的运气：

<?php
include('Net/SSH2.php');

$ssh = new Net_SSH2('localhost', 22);
$ssh->login('username', 'password');

$ssh->read('[prompt]');
$ssh->write("su - user\n");
$ssh->read('Password:');
$ssh->write("Password\n");
echo $ssh->read('[prompt]');
?>

Answer 2

Ejabberd 有一个特殊帐户，如果我的 php exec 调用以以下开头：

su - ejabberd -c "ejabberd 命令..."

（没有密码......嗯）

Answer 3

如果您使用一个用户启动 ejabberd 然后使用另一个用户重新启动，有时会发生这种情况，所以它可能与通过 php 运行命令的用户有关？

Answer 4

避免使用 sudo，将 ejabberd cookie 复制到您的 www 用户并直接调用 ejabberdctl。

此外，您可能希望查看 mod_xmlrpc，它允许您通过 XMLRPC 接口执行任何 ejabberdctl 命令。
