Problem access REST API Browser from GUI #2397

tachtler · 2016-06-22T12:05:09Z

Hi,

Graylog Version: 2.0.3
Elasticsearch Version: 2.3.3
MongoDB Version: 2.6.11
Operating System: CentOS 7.2
Browser version: Firefox ESR 45.2.0
HTTP-Server: Apache 2.4

graylog 2.0.3 works fine, BUT when I choose in the web gui | System | REST API Browser | a problem with loading the site occurs.

The link behind the REST API Browser are: graylog.domain.tld/api/api-browser

My configuration on Proxy-Apache:

<VirtualHost *:80>
        ServerName graylog.domain.tld
        ServerAlias www.graylog.domain.tld
        ServerPath /

        ProxyRequests Off
        ProxyPreserveHost On
        ProxyPass / http://192.168.0.110/
        ProxyPassReverse / http://192.168.0.110/
</VirtualHost>

My configuration on graylog-Apache:

<VirtualHost *:80>
        ServerName graylog.domain.tld
        ServerAlias www.graylog.domain.tld
        ServerPath /

        <Location />
                RequestHeader set X-Graylog-Server-URL "http://graylog.domain.tld/api/"
                ProxyPass http://127.0.0.1:9000/
                ProxyPassReverse http://127.0.0.1:9000/
        </Location>
        <Location /api/>
                ProxyPass http://127.0.0.1:12900/
                ProxyPassReverse http://127.0.0.1:12900/
        </Location>
</VirtualHost>

The apache configuration was done, as described here: http://docs.graylog.org/en/latest/pages/configuration/web_interface.html#apache-httpd-2-x

The Browser will display the following site:

And the page source will be the following code:

Every link inside the HTML-Code will start with /api-browser and NOT with /api/api-browser.

Maybe this could be the problem, because when i manually enter the URL with /api/api-browser, the href or script scr will be loaded, by the browser.

What did I wrong, on my setup?

Thank you for the help!

I am facing the same Problem but i get a little bit further now with this Config:
Important is not to set spdy in nginx! If you set it, you will get only sdpy errors

server {
      listen 443 ssl;
      server_name xxxx.local;

      ssl on;
      ssl_certificate /etc/nginx/ca/graylog.crt;
      ssl_certificate_key /etc/nginx/ca/graylog.key;
      ssl_session_timeout 5m;
      ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
      ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES12$
      ssl_prefer_server_ciphers on;

      location / {
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header    Host $http_host;
        proxy_set_header    X-Graylog-Server-URL https://xxxxx.local/api;
        proxy_pass          http://127.0.0.1:9000;
      }

      location /api/ {
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header    Host $http_host;
        proxy_pass          http://127.0.0.1:12900/;
      }

      location /api-browser {
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        rewrite ^/api/(.*) /$1 break;
        proxy_pass http://127.0.0.1:12900;
      }

Now i come this far:

Maybe the major problem is swagger and the HashBang so the rest of the page is something like https://xyz.local/api-browser#!/Alerts .
