java - 在 Windows 10 上使用 Clojure/Java 的 NginX - 未启动

Question

我遇到了 Nginx 没有启动的问题。按照步骤 - 在 link 中也提到了-->我下载了包含 nginx-clojure-0.4.4 的 .zip 文件，并将其解压缩到 C:\nginx。我的 .conf 文件如下所示:

daemon  off;

#master_process  off;
#user  nobody;
worker_processes  1;
error_log  logs/error.log;
pid        logs/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    #jvm_path auto;
    jvm_path 'C:/Program Files/Java/jdk1.8.0_91/jre/bin/server/jvm.dll';
    jvm_var my_other_jars 'C:/nginx-clojure-0.4.4/jars';
    jvm_classpath "#{my_other_jars}/*.jar;libs/*";
    #jvm_options "-Djava.class.path=jars/nginx-clojure-0.4.0.jar;#{my_other_jars}";
    jvm_options "-Xms1024m";
    jvm_options "-Xmx1024m";
    server {
        #listen       8080;
        listen       9091;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
    location /java {
        content_handler_type 'java';
        content_handler_name 'mytest.HelloService';
    }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

       location /clojure {
          handler_type 'clojure';
          handler_code ' 
                        (fn[req]
                          {
                            :status 200,
                            :headers {"content-type" "text/plain"},
                            :body  "Hello Clojure & Nginx!" 
                            })
          ';
       }       
    }
}

现在我运行 nginx-win64.exe 如下:

Windows PowerShell
Copyright (C) 2016 Microsoft Corporation. All rights reserved.

PS C:\WINDOWS\system32> cd c:\nginx
PS C:\nginx> .\nginx-win64.exe
PS C:\nginx>

当我转到 localhost:9091 时，页面没有加载，这意味着 nginx 没有启动。

这是 .log 文件的快照:

@dscastro评论后的error.log文件如下:

Answer 1

很简单...它找不到类 nginx.clojure.MiniConstants 因为它不在你的类路径中。

这个类放在 nginx-clojure-0.4.4.jar 中，所以将 jvm_classpath 更改为:

jvm_classpath "jars/nginx-clojure-0.4.4.jar;#{my_other_jars}/*.jar;libs/*;";

...错误应该消失了。 :)
