Restart Ruby and Rails application

How to Restart  Ruby and Rails application by using ssh ?
Ans :

You can restart your ruby and rails application by using following command.

Syntax :

/usr/bin/ruby -I /home/USERNAME/ruby /usr/bin/mongrel_rails start -p PORT -d -e ENVIRONMENT -P log/mongrel.pid

This should be executed in the root directory of the Rails app you wish to run on Mongrel. There are numerous options you can specify, including:

* -p port: run on a specific port
* -e environment: execute with a specific Rails environment, like production or development
* -d: run in daemon mode

1) First step is to check your rails application is running or not. If it is running then it shows the following output.

root@server[/home/USERNAME/rails_apps/aplication_name]#  ps -aux | grep ruby | grep USERNAME

root     15188 0.5  0.4  57472 52572 ?        S    01:15   0:03 /usr/bin/ruby -I /home/USERNAME/ruby /usr/bin/mongrel_rails start -p 12029 -d -e development -P log/mongrel.pid

2) To stop the already running rails application by using kill command


root@server[/home/USERNAME/rails_apps/aplication_name]# kill -9 15188

3) Then start same rails application by using following command with the same port on which it is running before.

/usr/bin/ruby -I /home/USERNAME/ruby /usr/bin/mongrel_rails start -p 12029 -d -edevelopment -P log/mongrel.pid

4) Done

Note :Replace the USERNAME equal to original username and the PORT(12029) equal to original running port number.
