我在尝试让Nginx代理另一台同样在Docker中运行的服务器的路径时遇到了问题。
为了说明,我以Nexus服务器为例。
这是我的第一次尝试......
docker-compose.yml
: -
version: '2'
services:
nexus:
image: "sonatype/nexus3"
ports:
- "8081:8081"
volumes:
- ./nexus:/nexus-data
nginx:
image: "nginx"
ports:
- "80:80"
volumes:
- ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
nginx.conf
: -
worker_processes 4;
events { worker_connections 1024; }
http {
server {
listen 80;
location /nexus/ {
proxy_pass http://localhost:8081/;
}
}
}
当我点击http://localhost/nexus/
时,我会使用以下日志获得502 Bad Gateway: -
nginx_1 | 2017/05/29 02:20:50 [error] 7#7: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: , request: "GET /nexus/ HTTP/1.1", upstream: "http://[::1]:8081/", host: "localhost"
nginx_1 | 2017/05/29 02:20:50 [error] 7#7: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 172.18.0.1, server: , request: "GET /nexus/ HTTP/1.1", upstream: "http://127.0.0.1:8081/", host: "localhost"
nginx_1 | 172.18.0.1 - - [29/May/2017:02:20:50 +0000] "GET /nexus/ HTTP/1.1" 502 575 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36"
在我的第二次尝试中......,
docker-compose.yml
- 我将links
添加到Nginx配置中: -
version: '2'
services:
nexus:
image: "sonatype/nexus3"
ports:
- "8081:8081"
volumes:
- ./nexus:/nexus-data
nginx:
image: "nginx"
ports:
- "80:80"
volumes:
- ./nginx/nginx.conf:/etc/nginx/nginx.conf:ro
links:
- nexus:nexus
nginx.conf
...我使用http://localhost:8081/
而不是http://nexus:8081/
: -
worker_processes 4;
events { worker_connections 1024; }
http {
server {
listen 80;
location /nexus/ {
proxy_pass http://nexus:8081/;
}
}
}
现在,当我点击http://localhost/nexus/
时,它会正确代理,但会部分呈现网络内容。在检查该页面的HTML源代码时,javascript,样式表和图像链接指向http://nexus:8081/[path]
...因此,404。
我应该更改什么才能让它正常工作?
非常感谢。

我使用的是以下附加选项
Type[] formatStringArgs = { typeof(string), typeof(int), typeof(string), typeof(int) };
MethodInfo formatString = typeof(String).GetMethod("Format", formatStringArgs);
il = toStringMethod.GetILGenerator();
il.Emit(OpCodes.Nop);
il.Emit(OpCodes.Ldstr, "{0},{1},{2}");
il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Call, getIdMethodeBuilder);
il.Emit(OpCodes.Box, typeof(Int32));
il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Call, getDescriptionMethodeBuilder);
il.Emit(OpCodes.Ldarg_0);
il.Emit(OpCodes.Call, getParentIdMethodeBuilder);
il.Emit(OpCodes.Box, typeof(Int32));
il.Emit(OpCodes.Call, formatString);
il.Emit(OpCodes.Ret);
typebuilder.DefineMethodOverride(toStringMethod,
typeof(object).GetMethod("ToString"));
}
我的解决方案是包含' /'的重定向。 nginx配置中的路径。 Nexus应用程序将向' /'对于它不起作用的资源。
然而,这并不理想,并且不适用于为多个应用程序提供服务的Nginx配置。
docs
覆盖此配置并指示您需要将Nexus配置为在/nexus
上投放。这将使您能够按如下方式(从文档)配置Nginx减去上面的黑客。
http {
server {
listen 80;
location /{
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
server_name_in_redirect on;
proxy_pass http://nexus:8081;
}
location /nexus/ {
proxy_pass http://nexus:8081/;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
server_name_in_redirect on;
}
}
我建议使用该配置。
