无法从 php 5.6 中删除甚至禁用 xdebug-2.5.5

Question

似乎在任何情况下我都无法从 php 中删除甚至禁用 xdebug，我做错了什么？

xdebug 甚至没有出现在 phpinfo() 或 print_r(get_loaded_extensions());

中

Array ( [0] => Core [1] => date [2] => ereg [3] => libxml [4] => openssl [5] => pcre [6] => zlib [7] => filter [8] => hash [9] => pcntl [10] => readline [11] => Reflection [12] => SPL [13] => session [14] => standard [15] => cgi-fcgi [16] => bcmath [17] => calendar [18] => ctype [19] => curl [20] => dom [21] => ftp [22] => gd [23] => imap [24] => json [25] => mcrypt [26] => mysqlnd [27] => mysql [28] => mysqli [29] => PDO [30] => pdo_mysql [31] => pdo_sqlite [32] => Phar [33] => posix [34] => SimpleXML [35] => sockets [36] => sqlite3 [37] => tokenizer [38] => xml [39] => wddx [40] => xmlreader [41] => xmlwriter [42] => xsl [43] => mhash )

正在尝试

    if(function_exists('xdebug_disable')) { xdebug_disable(); }

也什么都不做

php --ini 输出：

此外，在这些目录中搜索文本不会产生任何结果，xdebug 不在 php 表示它从以下位置加载的任何 ini 文件中：

find /opt/cpanel/ea-php56/root/etc/php.d/ -type f -exec grep -H 'xdebug' {} \;

这是 phpinfo():

不管怎样，我仍然尝试将其插入主 /opt/cpanel/ea-php56/root/etc/php.ini

xdebug.remote_autostart=0  
xdebug.remote_enable=0
xdebug.profiler_enable=0

正在寻找一个

zend_extension = "/path/to/xdebug.so"

指令不产生任何结果

我尝试在 /opt/cpanel/ 的根目录下进行搜索，但似乎仍然找不到任何相关内容，我在此处包含了 pastebin 上的输出：https://pastebin.com/4Ej1mdiR

find /opt/cpanel/ -type f -exec grep -H 'xdebug' {} \;

所以我回到 phpinfo() 输出到 extension_dir，本地值和主值都是：

ls /opt/cpanel/ea-php56/root/usr/lib64/php/modules

仍然没有 xdebug 模块

我试过了

service httpd restart

我已经进入 WHM 并重新启动了 PHP-Apache 的 FPM 服务，而 multiPHP ini 编辑器没有任何相关内容

我仍然无能为力，xdebug 似乎不存在并且仍在记录堆栈跟踪，导致敏感信息的内存泄漏！

如果有帮助的话，我使用 phpize 和 pecl 从源代码安装了 xdebug-2.5.5。

我尝试过的其他事情是进入 cPanel 的 WHM 并使用 Easy Apache 4 降级到 Apache Only 没有 PHP 然后重新安装 PHP，但仍然没有任何效果，仍然堆栈痕迹。我现在完全不知所措，连续工作了 4 天，我认为这对我来说没有意义。机器规格，我正在使用

uname -a
Linux myhost.com 3.10.0-514.10.2.el7.centos.plus.x86_64 #1 SMP Fri Mar 3 02:04:03 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

尝试从实际的官方 xdebug 网站开始遵循许多 uninstallation/removal 在线指南，但没有任何效果

非常感谢任何关于如何从我的系统中完全删除 xdebug 的建议！

编辑：仔细查看 /opt/cpanel 目录字符串搜索，我发现 xdebug 内置于 php-fpm 二进制文件 /opt/cpanel/ea-php56/root/usr/sbin/php-fpm.也许我需要重建 PHP-FPM，但我不确定如何在 cPanel

中进行

Answer 1

您的最后一次编辑说：

looking a little more closely at the /opt/cpanel directory string search I see that xdebug is built into the php-fpm binary at /opt/cpanel/ea-php56/root/usr/sbin/php-fpm.

我认为这是症结所在。如果它是内置的，那么你当然不能删除它。

但你也说：

xdebug isn't even showing up in phpinfo() or print_r(get_loaded_extensions());

这没有意义，因为 Xdebug 在加载时肯定会显示在其中。

所以我不明白 Xdebug 是怎么回事。

不过，你也说：

I still cannot do anything, xdebug appears to be inexistent and is still logging stack traces causing memory leaks of sensitive information!

这些到底是什么堆栈跟踪？
他们在哪里登录？

这些是例外情况吗？因为如果是这种情况，它们也可能只是正常的 PHP 堆栈跟踪（发布一个 header 可以很容易地确定）。而这些与Xdebug关系不大，可以通过php.ini中的display_errors=0；并在系统日志文件中使用 log_errors=0 和 error_log=（空字符串）。

无法从 php 5.6 中删除甚至禁用 xdebug-2.5.5
