使用 fastcgi-mono-server4 的 nginx 上的 Mono 2.11 将不起作用

Question

我使用我的 nginx 1.0.15 网络服务器设置了 Mono 2.11，该网络服务器在 centos 6.2 上运行。我从源代码构建它，xps2、xps4 和 fastcgi-mono-server2 按预期工作。问题是当我尝试运行 fastcgi-mono-server4 时。当我运行时：

fastcgi-mono-server4 /applications=site:/:/srv/www/html/ /socket=tcp:127.0.0.1:9000 /loglevels=Debug /printlog=true

这是我从 fastcgi-mono-server2 得到的：

我看不出我做错了什么。任何帮助都会很棒。

编辑：重新设计的东西，现在我收到错误网关的 502 错误。日志看起来仍然相同。

查看我的 Nginx 错误日志，发现很多类似这样的条目：

2012/06/18 13:56:01 [error] 3108#0: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.128.121, server: site, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "site"

无论 fastcgi-mono-server4 是否打开，我都会得到相同的响应。现在它总是显示 502 错误。

Answer 1

我的示例 MVC3 应用程序在来自 badgerports.org（我使用 ubuntu）的 Mono 2.10.8.1 上运行良好。

从源代码安装 Mono 2.11.2 后，相同的应用程序将始终返回 502 Bad Gateway，就像您的情况一样。

我的 nginx 日志如下所示：

[error] 3384#0: *101 upstream sent unexpected FastCGI record: 3 while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "localhost:8000"

在将 printlog 选项设置为 true 的情况下调用 fastcgi-mono-server4 之后

sudo /opt/mono-2.11.2/bin/fastcgi-mono-server4 /printlog=True /applications=/:/var/www/mono/Mvc3Template /socket=tcp:127.0.0.1:9000

它会在访问 localhost:8000/ 后生成此堆栈跟踪

这是我的一些配置：

#/etc/nginx/sites-enabled/mono

 server {
         listen   8000;
         server_name  localhost;
         access_log   /var/log/nginx/mono.access.log;
         error_log    /var/log/nginx/mono.error.log;
         location / {
                 root /var/www/mono/Mvc3Template;
                 index index.html index.htm default.aspx Default.aspx;
                 fastcgi_index /Home/Index; # Points to HomeController Index Action
                 fastcgi_pass 127.0.0.1:9000;
                 include /etc/nginx/fastcgi_params;
         }
 }

我在这里找到了解决我的问题的方法：bugzilla.xamarin.com/show_bug.cgi?id=2876（我的问题是它应该是在 2012 年 2 月修复的——我编译的单声道是在 6 月发布的 afaik 但它没有开箱即用）

我根据在那里找到的修复单声道安装的建议制作了一个脚本，只需将 PREFIX 变量指向您的单声道目录并运行它：

#!/bin/bash

# Your mono directory
PREFIX=/opt/mono-2.11.2


FILES=('mod-mono-server4'
       'fastcgi-mono-server4'
       'xsp4')

cd $PREFIX/lib/mono/4.0

for file in "${FILES[@]}"
do
   cp "$file.exe" ../4.5
done


cd $PREFIX/bin

for file in "${FILES[@]}"
do
  sed -ie 's|mono/4.0|mono/4.5|g' $file
done

在此之后，应用程序“工作”，但还没有完全到位。它不再是 502，我得到了一个很好的堆栈跟踪......
