Inventor's Paradox

This post would describe how we deploy a Yii application into Openshift Origin. It should also work in Openshift Enterprise and Openshift online. Challenges PHP-based application that runs in a Gear must not write to the application directory, because it is not writable. Openshift provides a Data Directory for each gear, which we could use for the purpose of writing assets and application runtime log. For the case of load-balanced application, error messages written to application log is also stored in multiple gears, making troubleshooting more complex than it is. Solution Use deploy action hook in order to create directories in the data directory and symbolic links to the application. Change the deploy script to be executable, in Windows systems without TortoiseGit we need to do some git magic. Create this file as .openshift/action_hooks/deploy in the application source code. If your application is hosted using 'php' directory in the source code : If your a...

Sometimes we just need to forward a port from one host, to another host. A few years back I built a java NIO-based port forwarder to learn about java NIO socket communication. The java source codes since has been lost and there is a different need for port forwarding, the first is that a server having failure connecting to services in another server, and I think that the server's IP  might be translated to another IP while it were connecting to another network. So the port forwarding need to be able to log the IPs of the incoming  connection. The second, is to temporarily circumvent strange network problems that prevent the first server connecting to another server. Step 1 - Decide which incoming port to use First we need to decide what port we are going to use to accept connections in the first host. Check first that the port is not already occupied in the host (try opening http://127.0.0.1:xx in your favorite browser where xx is the chosen port) Step 2 - Open windows...
