Rails core has moved to GitHub

Ya, Ruby on Rails core is now hosted at GitHub, which is uses Git for easy, fast, efficient, distributed version control system and also which looks pretty!!!

In DHH own words,

GitHub has now officially launched and Rails is right there at the premiere. The Rails repository now lives at rails/rails

And you can check it out with:

git clone git://github.com/rails/rails.git

But you will first need Git installed on your machine. For those on Windows machine, you can get that here: msysgit

Also people should have a look at this excellent post by Tim Pope on how to best use Git with Rails. You can have a look at the full tutorial also.

Steps to Restart a Server on a Linux (ubuntu) Box for Rails, Mongrel and Merb stack

Actually the title should read as

“Restarting Rails, Merb (a file upload framework) and Mongrel (a lightweight Web Server) Cluster”

Well this is also more of a reminder to self. So here goes the steps as follows:

Step 1: First connect to the Box, where the application is running, using any telnet application like Putty. It can be downloaded from this page. You need to put in the login credentials. For example login: vivanista and its password.

Step 2: Then you need to go to the ‘app’ folder. The command to write at cmd line is:-

cd app

Step 3: Then You need to update the application folder with the latest files from SVN repository.The command to write at cmd line is:-

svn update

Step 4: NOw we need to kill the Mreb process which is running on the server. For that we need to find the Mreb’s process id using the ‘grep’ cmd. The command to write at cmd line is:-

ps ax|grep merb

Step 5: Now you get the process ids i.e. pids of the Mreb you need to kill before restart. You need to kill the pid which has ruby folder as its initial folder in the text. The command to write at cmd line is:-

kill -9 (here the Merb pid to kill)

Step 6: Again run the ‘grep’ cmd of Step 4 to check if the Merb process has been killed properly

Step 7: Now restart Mongrel Cluster.(Note: Advantage of using cluster instead of single instance mongrel server is that it helps in load balancing and hence better performance of the server).The command to write at cmd line is:-

mongrel_rails cluster::restart

Step 8: Then go to the merbuploader folder to restart Merb. So you will be in ‘/app/merbuploader /’. To go ‘merbuploader’ folder, the cmd is:-

cd merbuploader

Step 9: Now to restart Merb, the cmd is:-

merb -d

Step 10: Now to exit the server and putty application, the cmd is:-

exit
