and it is working.. but i could'nt connect to the webpage http://127.0.0.1:8080/ from another system in same network..
By default, galaxy will only be serving on 127.0.0.1 (localhost), which is a loopback and only accessible on the machine itself. Accessing 127.0.0.1 using another machine on the network is actually making requests to the machine you're trying that from, which I assume isn't running galaxy.
In your universe_wsgi.ini, you can edit this via the 'host' setting. Just use 0.0.0.0 to listen to all connections.
