nginx 使用 Tomcat 7 管理 SSL

Question

server.xml 中让 nginx 管理 SSL 的正确配置是什么？我当前的配置会导致“重定向循环”，除非我将 tomcat 标准连接标记为“安全”，这不是我想要的。我的应用程序需要 https 来处理所有请求，如果使用 http，则重定向到 https。如果我设置 secure="true" 它不再重定向但“重定向循环”消失了。我做错了什么？

我当前的tomcat server.xml：

 <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               URIEncoding="UTF-8"
               redirectPort="8443" proxyPort="443"/>

Nginx 配置：

  server {
        listen 80 default_server;
        server_name localhost, mydomain.com;

         location / {

        add_header 'Access-Control-Allow-Origin' '*';
         proxy_pass        http://localhost:8080/;
        proxy_redirect    off;
        proxy_set_header  Host               $host;
        proxy_set_header  X-Real-IP          $remote_addr;
        proxy_set_header  X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header  X-Forwarded-Proto  http;
        proxy_send_timeout 6000;
         }
        }
 server {
                 server_name localhost, mydomain.com;
                listen 443;

        ssl on;
        ssl_session_timeout 5m;
        ssl_protocols SSLv2 SSLv3 TLSv1;
        #make sure you already have this certificate pair!
        ssl_certificate /etc/nginx/cert/server.crt;
        ssl_certificate_key /etc/nginx/cert/server.key;
        ssl_session_cache shared:SSL:10m;
        error_page 497 https://$host:$server_port$request_uri;

        # Our endpoint for tomcat reverse-proxy, assuming your endpoint java-servlet knows
        # how to handle http://localhost/gadgets  requests
        location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header X-Url-Scheme $scheme;
            proxy_redirect off;
            proxy_connect_timeout      240;
            proxy_send_timeout         240;
            proxy_read_timeout         240;
            # note, there is not SSL here! plain HTTP is used
           proxy_pass http://localhost:8080/;
        }

     }

Answer 1

需要处理 Tomcat 中的 x-forwarded-by 和 x-forwarded-proto 标头。将以下内容添加到您的 server.xml：

<Valve className="org.apache.catalina.valves.RemoteIpValve"
           remoteIpHeader="x-forwarded-for"
           remoteIpProxiesHeader="x-forwarded-by"
           protocolHeader="x-forwarded-proto"
    />

Answer 2

我所做的更改是为了让 Tomcat/Spring 设置正确的安全 cookie 标志：

确保 Tomcat 在 server.xml 中运行 SSL (443) 重定向端口：

<Service name="Catalina">
  ...
  <Connector executor="tomcatThreadPool"
    port="9090" protocol="HTTP/1.1"
    connectionTimeout="20000"
    redirectPort="8443" />
  ...
</Service>

确保您的RemoteIpValve 已设置在您的主机内server.xml：

<Service name="Catalina">
  ...
  <Engine name="Catalina" defaultHost="localhost">
    ...
    <Host name="localhost"  appBase="webapps"
        unpackWARs="true" deployOnStartup="true" autoDeploy="true">
      ...
      <!-- Mark HTTP as HTTPS forward from SSL termination at nginx proxy -->
      <Valve className="org.apache.catalina.valves.RemoteIpValve"
        remoteIpHeader="x-forwarded-for"
        remoteIpProxiesHeader="x-forwarded-by"
        protocolHeader="x-forwarded-proto"
        />
    </Host>
  </Engine>
</Service>

确保协议是从nginx.conf 中的终止点转发的：

# Tomcat we're forwarding to
upstream tomcat_server {
  server 127.0.0.1:9090 fail_timeout=0;
}

# Main server proxy
server {
  listen 443 ssl;
  server_name  sample.com;

  # HTTPS setup
  ssl on;
  ssl_session_timeout 10m;
  ssl_session_cache shared:SSL:10m;

  #ssl cyphers
  ... 
  #ssl certs
  ... 

  location / {

    # Forward SSL so that Tomcat knows what to do
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Forwarded-Server $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://tomcat_server;
    proxy_set_header X-Forwarded-Proto https;

    proxy_redirect off;
    proxy_connect_timeout      240;
    proxy_send_timeout         240;
    proxy_read_timeout         240;

    # Show error pages from S3 when down
    proxy_next_upstream error timeout http_502 http_503 http_504;
    error_page   502 503 504   https://s3.amazonaws.com/sample.com/maint;
}

为了完整起见，我的大部分代理/SSL nginx conf 都包含在上面。希望对某人有所帮助。
