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.
