PHPStorm - vagrant 上的“无法接受外部 xdebug 连接”

Question

我正在尝试 - 未成功 - 使用 PHPstorm/xdebug/vagrant 组合。每次我尝试调试某些东西时，PHPStorm 都会抛出一个Cannot accept external xdebug connection 错误。

这是 xdebug 配置：

[xdebug]
zend_extension="/usr/lib/php5/20131226/xdebug.so"
extension=xdebug.so
xdebug.remote_enable = on
xdebug.remote_connect_back = on
html_errors=1
xdebug.extended_info=1
xdebug.remote_log="/var/log/xdebug/xdebug.log"
xdebug.remote_port = 9000
xdebug.remote_autostart = 0
xdebug.idekey = "vagrant"
xdebug.default_enable = 1
xdebug.remote_host=192.168.33.10

下图显示了我的 phpstorm 配置：

另外，我的输出来自php -i | grep xdebug：

我的主机运行的是 Elementary OS，而我的 vagrant box 运行的是 Scotch box（所以，两者都是 ubuntu 14.04）。

主要问题是：如何设置 PHP 以在我当前的环境中使用 xdebug 调试我的 PHP 代码？

Answer 1

刚刚从 xdebug.ini 中删除了 extension=xdebug.so 行，它就像一个魅力。

谢谢@LazyOne，你的回答拯救了我的一天:)
