安装了 Xdebug 但我在 phpinfo 中找不到它

Question

我已经安装了 Xdebug，但在phpinfo()输出中找不到它。

我根据https://xdebug.org/wizard.php 操作：

量身定制的安装说明摘要

Xdebug installed: no
Server API: FPM/FastCGI
Windows: no
Zend Server: no
PHP Version: 7.2.14-1
Zend API nr: 320170718
PHP API nr: 20170718
Debug Build: no
Thread Safe Build: no
OPcache Loaded: no
Configuration File Path: /etc/php/7.2/fpm
Configuration File: /etc/php/7.2/fpm/php.ini
Extensions directory: /usr/lib/php/20170718

指示

Download xdebug-2.7.0.tgz
Install the pre-requisites for compiling PHP extensions.
On your Ubuntu system, install them with: apt-get install php-dev autoconf automake
Unpack the downloaded file with tar -xvzf xdebug-2.7.0.tgz
Run: cd xdebug-2.7.0

Run: phpize (See the FAQ if you don't have phpize).

As part of its output it should show:

Configuring for:
...
Zend Module Api No:      20170718
Zend Extension Api No:   320170718

If it does not, you are using the wrong phpize. Please follow this FAQ entry and skip the next step.
Run: ./configure
Run: make
Run: cp modules/xdebug.so /usr/lib/php/20170718
Edit /etc/php/7.2/fpm/php.ini and add the line
zend_extension = /usr/lib/php/20170718/xdebug.so
Restart the webserver

重启php和nginx，还是不行。

当我执行php -m|grep xdebug它返回：

加载 /usr/lib/php/20180731/xdebug.so 失败：/usr/lib/php/2017/xdebug.so：未定义符号：zend_post_startup_cb

我不知道是什么zend_post_startup_cb；我在网站上找不到任何信息。

尝试从这里安装

sudo apt-get install php-xdebug

您可以在此处找到 xdebug.ini（适用于 php 7.2 版）

vi /etc/php/7.2/mods-available/xdebug.ini //zend_extension=xdebug.so
