support for nginx server configuration ??

[ashwintastic]

Hi I have installed nginx-push-stream-module version 1.8.0 I have pasted the following code in /etc/nginx/nginx.conf

       location /channels-stats {
   
           push_stream_channels_statistics;

   
              push_stream_channels_path               $arg_id;
      }

     location /pub {
    
              push_stream_publisher admin;

              push_stream_channels_path               $arg_id;
     }

      location ~ /sub/(.*) {
   
               push_stream_subscriber      long-polling;
 
               push_stream_channels_path         $1;

              push_stream_message_template                "                     {\"id\":~id~,\"channel\":\"~channel~\",\"text\":\"~text~\"}";

    
              push_stream_longpolling_connection_ttl        30s;
        }

but getting this error nginx: [emerg] unknown directive "push_stream_channels_statistics" in /etc/nginx/nginx.conf:240

where I'm doing wrong !!

Do you mind to paste the nginx -V output and describe how you installed the module?

[ashwintastic]

ThnQ for quick response nginx -V gives this

I have followed thses steps:

https://github.com/wandenberg/nginx-push-stream-module#installation-

       nginx version: nginx/1.10.0 (Ubuntu)

[wandenberg]

@HiteshSomani you probably missed to use --add-module=../nginx-push-stream-module on your configure command. There is no reference to pushstream module on nginx -V output.
If you are trying to use the dynamic version, please take a look on how to build it on Nginx documentation. If not, add the command above to your configuration and repeat the compile and install steps again.

[ashwintastic]

@wandenberg I have used --add-module=../nginx-push-stream-module but still getiing the same issue.. I need to confirm where I have to configure the http context ? now I have done at /etc/nginx/nginx.conf

[wandenberg]

Please, share the full command you are using, and your folder structure, and also your nginx.conf.

[ashwintastic]

command that i'm using : sudo nginx to start server

getting this error nginx: [emerg] unknown directive "push_stream_channels_statistics" in /etc/nginx/nginx.conf

nginx.cong

   server{
 

  location /channels-stats {
   
    push_stream_channels_statistics;

   
    push_stream_channels_path               $arg_id;
}

location /pub {
    
    push_stream_publisher admin;

    
    push_stream_channels_path               $arg_id;
}

location ~ /sub/(.*) {
   
    push_stream_subscriber      long-polling;

   
    push_stream_channels_path         $1;

    
    push_stream_message_template                "{\"id\":~id~,\"channel\":\"~channel~\",\"text\":\"~text~\"}";

    
    push_stream_longpolling_connection_ttl        30s;
}

}

[wandenberg]

Not the command to start the server. The command to configure, build and install the nginx.
Probably you made a mistake on it, or forgot to recompile and reinstall after add the --add-module

[ashwintastic]

command I used : I used exactly these steps to install installation

for configuration I added this code configuration in /etc/nginx/nginx.conf:

[wandenberg]

So, for sure you skip some step because on the output of you nginx -V does not contain the word 'push' for example and it must be there if you 1) configure the module with --add-module ... 2) recompile the nginx with make and 3) reinstalled it with sudo make install

Cool Its working but not able to do this curl -s -v --no-buffer 'http://localhost/sub/my_channel_1'

    Trying 127.0.0.1...
    *  connect to 127.0.0.1 port 80 failed: Connection refused
    * Failed to connect to localhost port 80: Connection refused
    * Closing connection 0

any idea !!

I think server is not yet started but I have run this command sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf

[wandenberg]

what shows on logs and stdout when you executed sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf?
(just to remember this misc/nginx.conf must not be used for other purposes than testing.)

[ashwintastic]

nothing gets printed !!!

[wandenberg]

I suggest you to uninstall everything and starts over, step by step. :)

[ashwintastic]

after reinstalling getting this

nginx: [emerg] invalid event type "poll" in /home/ashwinik/pusher/nginx-push-stream- module/misc/nginx.conf:19

to fix the above I made a change
nginx: configuration file /home/ashwinik/pusher/nginx-push-stream-module/misc/nginx.conf test failed

[wandenberg]

replace poll with epoll if you are on linux and with kqueue if on MacOS

[ashwintastic]

yes I did it :)

[ashwintastic]

after this command sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf when I hit localhost for channel subcription

curl -s -v --no-buffer 'http://localhost/sub/my_channel_1' nothing is logging

[ashwintastic]

Infact curl -I http://localhost/ gives this curl: (7) Failed to connect to localhost port 80: Connection refused which means server is not yet started ... but I run this command sudo /usr/local/nginx/sbin/nginx -c $NGINX_PUSH_STREAM_MODULE_PATH/misc/nginx.conf

[wandenberg]

the request to /sub location is only logged when it finish. It is a stream connection.
Also, if you are using the misc/nginx.conf without changing the listen line the nginx is listening on 9080 port, not 80.

[wandenberg]

@HiteshSomani I created a Vagrantfile for you.
Just execute a vagrant up and after that you will be able to execute curl --raw localhost:9080/sub/ch1 in one terminal and curl localhost:9080/pub?id=ch1 -d ABC in another.

remamber to rename the file from Vagrantfile.txt to Vagrantfile
Vagrantfile.txt

@wandenberg ThnQ It's working woopi !!!
