Mono + apache2 = 服务暂时不可用 (503) [英] Mono + apache2 = Service Temporarily Unavailable (503)

问题描述

一个星期以来，我一直试图让我的单声道配置与 apache 一起运行.我必须尝试过几乎任何东西，可耻的是我没有注意到任何变化，问题仍然存在.

For a week now I've been trying to get my mono configuration running with apache. I must have tried virtually anything, shamefully I notice no changes, the problem remains the same.

当我尝试连接到服务器时，出现 503 错误:服务暂时不可用当我查看错误日志时，它看起来是空的，我很确定这不是权限问题.

When I try to connect to the server I get a 503 error: Service Temporarily Unavailable When I take a look at the errror log it appears empty and I'm quite sure it's not an permission problem.

我正在使用下面的配置.

I am using the configuration below.

<VirtualHost *:80>
  ServerName myapp.example.com
  ServerAdmin [e-mail]
  DirectoryIndex index.html index.aspx
  DocumentRoot /var/www/vhosts/example.com/subdomains/myapp/httpdocs/

  # MonoServerPath can be changed to specify which version of ASP.NET is hosted
  # mod-mono-server1 = ASP.NET 1.1 / mod-mono-server2 = ASP.NET 2.0
  # For SUSE Linux Enterprise Mono Extension, uncomment the line below:
  # MonoServerPath myapp.example.com "/opt/novell/mono/bin/mod-mono-server2"
  # For Mono on openSUSE, uncomment the line below instead:
  MonoServerPath myapp.example.com "/usr/bin/mod-mono-server2"
  #mod-mono-server2

  # To obtain line numbers in stack traces you need to do two things:
  # 1) Enable Debug code generation in your page by using the Debug="true"
  #    page directive, or by setting <compilation debug="true" /> in the
  #    application's Web.config
  # 2) Uncomment the MonoDebug true directive below to enable mod_mono debugging
  MonoDebug myapp.example.com true
  # The MONO_IOMAP environment variable can be configured to provide platform abstraction
  # for file access in Linux.  Valid values for MONO_IOMAP are:
  #    case
  #    drive
  #    all
  # Uncomment the line below to alter file access behavior for the configured application
  MonoSetEnv myapp.example.com MONO_IOMAP=all
  #
  # Additional environtment variables can be set for this server instance using
  # the MonoSetEnv directive.  MonoSetEnv takes a string of 'name=value' pairs
  # separated by semicolons.  For instance, to enable platform abstraction *and*
  # use Mono's old regular expression interpreter (which is slower, but has a
  # shorter setup time), uncomment the line below instead:
  # MonoSetEnv myapp.example.com MONO_IOMAP=all;MONO_OLD_RX=1
  MonoApplications myapp.example.com "/:/var/www/vhosts/example.com/subdomains/myapp/httpdocs/"

  <Location "/">
    Order allow,deny
    Allow from all
    MonoSetServerAlias myapp.example.com
    SetHandler mono
    SetOutputFilter DEFLATE
    SetEnvIfNoCase Request_URI "\.(?:gif|jpe?g|png)$" no-gzip dont-vary
  </Location>
  <IfModule mod_deflate.c>
    AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript
  </IfModule>

  ErrorLog  /var/www/vhosts/example.com/subdomains/myapp/logs/error.log
  CustomLog /var/www/vhosts/example.com/subdomains/myapp/logs/access.log combined

</VirtualHost>

谁能帮帮我.

推荐答案

您是否尝试过 mod_mono AutoConfiguration 功能 ?这显然是 Apache/Mono/ASP.NET 堆栈的最佳方法.有了它，您不再需要在虚拟主机中定义所有 Mono 设置.

Have you tried the mod_mono AutoConfiguration feature ? This is clearly the best approach with the Apache/Mono/ASP.NET stack. With it, you don't need anymore to define all Mono settings in your virtual host.

这是我的 mod_mono.conf 文件(在 Mac OS X 10.7.2 和 Linux Ubuntu 11.04 上，这应该与您的 Debian 发行版兼容):

Here is my mod_mono.conf file (on Mac OS X 10.7.2 and Linux Ubuntu 11.04, this should be compatible with your Debian distro) :

<IfModule mono_module>
    AddType application/x-asp-net .config .cs .csproj .dll .resources .resx .sln .vb .vbproj
    AddType application/x-asp-net .asax .ascx .ashx .asmx .aspx .axd .browser .licx .master .rem .sitemap .skin .soap .webinfo

    MonoAutoApplication enabled
    MonoDebug false
    MonoServerPath "/usr/bin/mod-mono-server4"
    MonoSetEnv LANG=fr_FR.UTF-8
    MonoUnixSocket "/tmp/.mod_mono"

    <IfModule dir_module>
        DirectoryIndex Default.aspx
    </IfModule>

    <DirectoryMatch "/(bin|App_Code|App_Data|App_GlobalResources|App_LocalResources)/">
        Order deny,allow
        Deny from all
    </DirectoryMatch>

    <Location "/Mono">
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1 ::1
        SetHandler mono-ctrl
    </Location>
</IfModule>

最重要的指令是MonoAutoApplication"指令.这是一个示例虚拟主机:

The most important directive is the "MonoAutoApplication" one. And here is a sample virtual host :

<VirtualHost *:80>
    ServerName www.monorules.fr
    DocumentRoot "/Library/WebServer/Documents/MonoRules"
</VirtualHost>

如您所见，虚拟主机简化为最简单的表达方式.mod_mono.conf 文件中定义的设置由所有虚拟主机共享.
此解决方案的唯一缺点是它不允许您仅重新启动 ASP.NET 站点的一个实例(如在 Microsoft IIS 中).如果您使用 Mono 控制面板(请参阅位置"部分)重新启动该进程，则会重新启动所有 ASP.NET 应用程序.

As you can see, the virtual host is reduced to its simplest expression. The settings defined in the mod_mono.conf file are shared by all the virtual hosts.
The only drawback of this solution is that it does not let you restart only one instance of an ASP.NET site (as in Microsoft IIS). If you use the Mono control panel (see "Location" section) to restart the process, all ASP.NET applications are restarted.
