How to run datastax opscenter behind nginx

  • 772

I would like to run datastax cassandra opscenter behind Nginx. But it keeps adding opscenter port (8888 by default) to all urls. Is there a config setting to disable that or something?

Here is my super simple nginx config:

server {
  server_name opscenter.hostname.com;

  location / {
    proxy_pass http://127.0.0.1:8888;
  }
}

Is there something I'm doing wrong maybe?

  1. Solved this by adding nginx redirect to /opscenter

    location = / {
  rewrite (.*) /opscenter;
}

  2. You need to create location like the following:

    location / {
    proxy_pass http://127.0.0.1:8888;
    proxy_redirect http://localhost:8888/ /;
    proxy_redirect http://your.host.name:8888/ /;
    proxy_buffering off;

    }

    The proxy_redirect lines will strip the 8888 from the responses returned by OpsCenter.

    More info on what proxy_redirect does can be found at http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_redirect

  3. I tried the suggested configurations and more, but none of them worked for me.
    Here is my use case, and my solution.

    My servers

    Nginx and OpsCenter are both on 2 different machines. Unlike Nginx, OpsCenter is not accessible directly from the internet.

    Nginx 1.4.6 is on 172.132.1.2 (public network)
    OpsCenter 5.2.0 is on 172.132.2.3 (private network)

    Nginx Configuration

    upstream opscenter {
  server 172.132.2.3:8888;
}

server {
    listen 81 default_server;
    listen [::]:81 default_server ipv6only=on;

    location / {
         proxy_pass http://opscenter;
         proxy_redirect http://$proxy_host:8888/ http://$host:$server_port/;
         proxy_buffering off;
    }

    location ~ /\.ht {
        deny all;
    }
}
