Apache - Githubissues

kg4iae commented 6 years ago

Has anyone gotten this to work behind an Apache server. I've been working on it for days, and can't seem to get it to work.

Right now I get 400 errors on the WebSocket Connections. I can provide more information if anyone wants it.

My Apache config looks like:

ProxyPass / http://localhost:57575/ ProxyPassReverse / http://localhost:57575/

I've tried several things to get WS to play nice, but so far they have all failed.

Soon after I wrote this, I figured it out. In case anyone else needs the "Magic" here it is:

<VirtualHost *:80>
ServerName shell.MYSITE.com
ProxyPreserveHost On
RewriteEngine On
RewriteCond %{HTTP:UPGRADE} ^WebSocket$   [NC]
RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
RewriteRule .* ws://localhost:57575%{REQUEST_URI} [P]
ProxyPass / "http://localhost:57575/"
ProxyPassReverse / "http://localhost:57575"
</VirtualHost>

Hi kg4iae, I'm trying to do kind of the same thing but what I want to do is reroute the local port to a url on the same apache server. For example, http://localhost:8080 goes to the regular tomcat webpage. http://localhost:8080/butterfly/ should go to the butterfly login but I have not been able to get it to work successfully. It seems like you've gone down this path and I don't know where I should look to next. I have it almost working with (I'm using port 1234 for butterfly)

    ProxyPass /butterfly/ http://localhost:1234
    ProxyPassReverse /butterfly/ http://localhost:1234
    ProxyRequests On
    <Proxy *>
        Allow from all
    </Proxy>

but I just get a blank box. The page source looks like this -

Absolutely any ideas from anyone would be greatly appreciated. I've been banging my head against the wall about this for a few days now. Thanks all.

@dbiscan

Did you finally get this working? I'm trying to configure a reverse proxy in the same way and can't get it to work.

Thanks!

Sorry I didn't comment sooner. I just found the email notification from GitHub hidden in a folder I don't check.

Anyway, you have to use rewrite rules since Butterfly uses web sockets. Apache Proxy doesn't play well with sockets.

Copy the lines I shared above into a config file (butterfly.conf). Put it into your /etc/apache2/sites-available folder. Change ServerName, and if necessary butterfly port. I'm using the default 57575.

Run the a2ensite command to enable the new site.

Modify your DNS to include a CNAME record for something like 'shell.yoursite.com' -> 'www.yoursite.com'

You should be able to access the site by using: http://shell.yoursite.com

I tried to get it work using a virtual path, like you did, but never got that working.

Good luck.

ProxyPass / "http://localhost:57575/"
ProxyPassReverse / "http://localhost:57575"
</VirtualHost>

As of Apache 2.4.47, this can be simplified to:

<VirtualHost *:80>
ServerName shell.MYSITE.com
ProxyPreserveHost On
ProxyPass / "http://localhost:57575/" upgrade=websocket
ProxyPassReverse / "http://localhost:57575/"
</VirtualHost>
