Why capistrano

However when I run using Capistrano it says that permission denied to account dorelal. So I thought Capistrano is executing the task locally on my mac and not on my remote server which is on Redhat. Notice it says 'executing locally'.

Why is capistrano running it locally and not on my remote box.

Capistrano defines a standard deployment process that all Capistrano-enabled projects follow by default. You don't have to decide how to structure your scripts, where deployed files should be placed on the server, or how to perform common tasks: Capistrano has done this work for you.

Define your deployment once, and then easily parameterize it for multiple stages environments , e. No copy-and-paste necessary: you only need to specify what is different for each stage, like IP addresses. Deploying to a fleet of app servers? Capistrano can run each deployment task concurrently across those servers and uses connection pooling for speed.

Your application may need many different types of servers: a database server, an app server, two web servers, and a job queue work server, for example. Capistrano lets you tag each server with one or more roles, so you can control what tasks are executed where. Capistrano is easily extensible using the rubygems package manager.

Deploying a Rails app? Chances are, someone has already written Capistrano tasks for your framework of choice and has distributed it as a gem. Many Ruby projects also come with Capistrano tasks built-in. Everything in Capistrano comes down to running SSH commands on remote servers.

On the one hand, that makes Capistrano simple. On the other hand, if you aren't comfortable SSH-ing into a Linux box and doing stuff on the command-line, then Capistrano is probably not for you. While Capistrano ships with a strong set of conventions that are common for all types of deployments, it needs help understanding the specifics of your project, and there are some things Capistrano is not suited to do.

Does foreman need to be run? Does Apache need to be restarted? You'll need to tell Capistrano how to do this part by writing these deployment steps yourself, or by finding a gem in the Capistrano community that does it for you. Capistrano depends on connecting to your server s with SSH using key-based i.

More roles for servers Capistrano assigns each server with one or more roles to control the tasks that are executed, as the application may need different types of servers for database, application, web etc.
