Symfony2 部署时出现错误 500

Question

几天来我一直在为一个奇怪的错误而苦苦挣扎。到目前为止，我设法创建了一个工作应用程序，在本地一切正常。我尝试部署我的应用程序，但收到以下消息：

内部服务器错误

服务器遇到内部错误或配置错误，并且 无法完成您的请求。

由于这是我的第一次部署，我完全不知道在哪里查看。我搜索了一段时间，使用了调试器，使用 Insight 修复了每个主要和严重错误，但我仍然收到相同的错误消息。

最大的问题是我根本没有日志。我授予了对 app/cache 和 app/logs 的所有访问权限，但没有在服务器上创建日志文件。

我得到它的工作，这是我的经验：

Upload the whole project folder to the server.
Enter www.your-website.com/project-name/web/config.php.
It should say: "This script is only accessible from localhost".
Open this web site: http://www.whatismyip.com, it should show you your public IP address, copy it.
Open the config.php from the admin panel (like cPanel) and edit that config.php:

if (!in_array(@$_SERVER['REMOTE_ADDR'], array('127.0.0.1', '::1', /你的 IP/))) { header('HTTP/1.0 403 禁止'); die('这个脚本只能从 localhost 访问。');
}

Refresh your config.php file, the page will tell you if your system is missing some required conditions like: PHP version, APC extension, giving /cache and /log folders permissions to write on, etc.
After you provide the required conditions you'll see a form of configuring you project to connect to a database if you have one, this step is pretty simple.
Open the link www.your-website.com/project-name/web/app_dev.php, it'll help you get started with Symfony2 project.
In case you got in app_dev.php this message: You are not allowed to access this file... just do the same thing to app_dev.php as you did in steps 4 and 5 (add your public IP address to the array).
Note of Hakan Deryal (comment): If you don't have a fix IP address, you need to do this last step each time you get a new IP adrdress from the DHCP. So to solve that, open the app_dev.php and comment out the line die('You are not allowed to.., however this is not a recommended way because you're disabling the built-in security of the file.
One thing stopped me and may stop you too, the server I deployed the project on, was case-sensitive (unlike the localhost on my computer), so it kept telling me that the template (Index.html.php for example) does not exist, however it does exist, but I did return $this->render('...:index.html.php') with small i in DefaultController.php. So render the exact template (file) name with the same letters cases.

现在一切顺利，希望对你有所帮助。
