I'm trying to deploy my rails application with capistrano, but I'm having some trouble running my migrations. In my development environment I just use sqlite as my database, but on my production server I use MySQL.
The problem is that I want the migrations to run from my server and not my local machine, as I am not able to connect to my database from a remote location.
My server setup:
A debian box running ngnix, passenger, mysql and a git repository.
What is the easiest way to do this?
update:
Here's my deploy script: (i replaced my actual domain with example.com)
set :application, "example.com"
set :domain, "example.com"
set :scm, :git
set :repository, "git#example.com:project.git"
set :use_sudo, false
set :deploy_to, "/var/www/example.com"
role :web, domain
role :app, domain
role :db, "localhost", :primary => true
after "deploy", "deploy:migrate"
When I run cap deploy, everything is working fine until it tries to run the migration.
Here's the error I'm getting:
** [deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: localhost (Errno::ECONNREFUSED: Connection refused - connect(2))
connection failed for: localhost (Errno::ECONNREFUSED: Connection refused - connect(2)))
This is why I need to run the migration from the server and not from my local machine.
Any ideas?
Try to add
after "deploy", "deploy:migrate"
in your config/deploy.rb file. This will run a migration on your server upon a successful deployment of your project.
Have you added your deploying user as a mysql user on the server? I reckon the localhost is the server referring to itself not your local machine.
Also you haven't defined your user in your deploy script:
set :user, "deploy_user_name"
role :web, domain
role :app, domain
role :db, domain, :primary => true

So I'm going through this tutorial http://blog.grio.com/2012/07/how-to-deploy-your-web-app-to-amazon-ec2-using-capistrano.html to deploy a rails app to EC2, and I'm confused about a few things in deploy.rb. In the default version of the file, I have:
role :web, "your web-server here" # Your HTTP server, Apache/etc
role :app, "your app-server here" # This may be the same as your `Web` server
role :db, "your primary db-server here", :primary => true # This is where Rails migrations will run
role :db, "your slave db-server here"
However, previously I was hosting on heroku where I was assigned a url. Since this will be a facebook app, I don't want to deal with getting a url, so is there anything I can do to get one automatically like I did on heroku? Also, what is the idea behind this, ie what is it doing?
set :deploy_to, "/var/www/myapp"
When you run Capistrano, you are running it from your local machine.
The:
"your web-server here"
is for the IP address of the remote server you are deploying your app to.
The:
set :deploy_to
is specifying the folder on the server you want.
I have set up amazon EC2 instance (working) and Github repo (working well).
When I try to deploy the app to EC2 with using Github repo, I get this error:
** [IP] Permission denied (publickey).
** [IP] fatal: Could not read from remote repository.
**
** Please make sure you have the correct access rights
** and the repository exists.
What am I missing? I can deploy an app to EC with using copy, but not with using github.
What do I need to set up the publickey?
EDIT: SETUP
set :application, "project_name"
set :user, 'username'
set :password, "password"
set :domain, "IP.amazonaws.com"
set :deploy_to, "/path_to_directory"
set :use_sudo, false
role :web, domain
role :app, domain
role :db, domain, :primary => true
set :assets_role, [:app]
default_run_options[:pty] = true
set :repository, "git#github.com:user/repo.git"
set :scm, "git"
Thank you
You haven't set up your SSH keys between EC2 and Github correctly based on the error message, but given the information you've provided, it's not possible to provide suggestions.
Question - have you set up a deploy key on the EC2 server? I'm assuming that you are trying to deploy from the EC2 server and not your local machine using SSH Agent Forwarding. Can you do a git pull from the EC2 server to the github account? Can you ssh to git#github.com (e.g. "ssh -T git#github.com")?
The links below can help you setup a deploy key or figure out another way to manage deployment.
https://help.github.com/articles/deploying-with-capistrano
https://help.github.com/articles/managing-deploy-keys
One of the best ways to debug access privileges when beginning to use Capistrano is to try accessing your server without it.
I have setup everything and i am able to connect to the server via ssh on a free tier
now my project is how can i upload the server files and database?
I see that there are some gems in rails such as rubber that deploy the files to a server but how can i also integrate git so i can commit changes as well?
Code
For uploading the files, check out capistrano. Another popular tool is Vlad the deployer.
Here's a simple deploy.rb for a rails3 app (assuming passenger) that only needs one server right now (replace all the with actual values):
require 'bundler/capistrano'
require 'capistrano_colors'
set :application, "<APP_NAME>"
set :repository, "git#github.com:<USER>/<PROJECT>.git"
set :branch, "master"
set :deploy_to, "/home/<DEPLOY_USER>/<APP_NAME>"
set :keep_releases, 3
set :scm, :git
set :user, "<DEPLOY_USER>"
set :use_sudo, false
set :deploy_via, :remote_cache
default_run_options[:pty] = true
default_run_options[:shell] = '/bin/bash -l'
ssh_options[:forward_agent] = true
role :web, "<IP_OR_PUBLIC_DNS>"
role :app, "<IP_OR_PUBLIC_DNS>"
namespace :deploy do
task :start do ; end
task :stop do ; end
task :restart, :roles => :app, :except => { :no_release => true } do
run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
end
end
after "deploy", "deploy:cleanup"
Note: you should ssh-add the private keys for the deploy user as well as the key you use for github before running cap deploy. (e.g. ssh-add ~/.ssh/id_dsa)
Database
In terms of the database, you can run migrations as part of a deploy via cap deploy:migrations, or independently via cap deploy:migrate. Just be sure to list a server with role :db
role :db, "<IP_OR_PUBLIC_DNS>", :primary => true
(Note: this is the server that will be used to run the migrations, not the actual db. The db should be specified in your database.yml).
Setting up the database itself is beyond the scope of this answer, but you can either run a db directly on the instance, or take a look at Amazon's RDS, which is really simple to set up and more stable than a db running on a single instance.
I'm getting a port error when I try to deploy my app via:
cap deploy:cold
The error:
ssh: connect to host domain.com port 22: Connection refused
My deploy.rb (replaced sensitive info where appropriate):
set :user, 'user'
set :domain, 'domain.com'
set :application, "App Name"
# file paths
set :repository, "user#domain.com:git/appname.git"
set :port, 9728
set :deploy_to, "/home/ruby/public_html/appname"
# distribute your applications across servers (the instructions below put them)
# all on the same server, definied above as 'domain', adjust as necessary
role :web, domain
role :app, domain
role :db, domain, :primary => true
# you might need to set this if you aren't seeing password prompts
# default_run_options[:pty] = true
# As Capistrano executes in a non-interactive mode and therefore doesn't cause
# any of your shell profile scripts to be run, the following might be needed
# if (for example) you have locally installed gems or applications. Note:
# this needs to contain the full values for the variables set, not simply
# the deltas.
# miscellaneous options
set :deploy_via, :remote_cache
set :scm, :git
set :branch, 'master'
set :scm_verbose, true
set :use_sudo, false
# task which causes Passenger to initiate a restart
namespace :deploy do
task :restart do
run "touch #{current_path}/tmp/restart.txt"
end
end
# optional task to reconfigure databases
after "deploy:update_code", :configure_database
desc "copy database.yml into the current release path"
task :configure_database, :roles => :app do
do_config = "#{deploy_to}/config/database.yml"
run "cp #{db_config} #{release_path}/config/database.yml"
end
I understand the error, but can't see where to make the change. I figured :set port, would handle it.
Have you tried putting the port in your repository path ? Something like ssh://user#domain.com:9728/git/appname.git
I think Capistrano only uses the port you specify in set :port to log in your remote servers.
Here's what works: you must have
set :port, port#
set :repository, "ssh://#{user}#IPAddress:#{port}/~/path/to/git
Or also try:
Here's a possible fix. add ssh_options[:port] = port# May work
Sorry to state the obvious, but:
Is the port actually open on the server?
Have you changed it to something else?
Is it accessible from the outside?
Is your firewall blocking it?
please try it
server "domain:9728", :web, :app, :db
I'm trying to deploy my rails application by using Passenger and Capistrano on Dreamhost. I'm using Git as a version control and we bought an account from GitHub.
I have installed all required gems, Passenger and Capistrano in my local machine and I have cloned the repository of my project from GitHub in my local machine as wel.
According to Dreamhost support, they have Passenger, Ruby, Rails and etc on their server as well.
I'm currently following this article http://github.com/guides/deploying-with-capistrano for my deployment.
The following is my deploy.rb.
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
# be sure to change these
set :user, 'gituser'
set :domain, 'github.com'
set :application, 'MyProjectOnGit'
#git#github.com:MyProjectOnGit.git
# the rest should be good
set :repository, "git#github.com:MyProjectOnGit.git"
set :deploy_to, "/ruby.michaelsync.net/"
set :deploy_via, :remote_cache
set :scm, 'git'
set :branch, 'master'
set :git_shallow_clone, 1
set :scm_verbose, true
set :use_sudo, false
set :git_enable_submodules, 1
server domain, :app, :web
role :db, domain, :primary => true
set :ssh_options, { :forward_agent => true }
namespace :deploy do
task :restart do
run "touch #{current_path}/tmp/restart.txt"
end
end
When I run "cap deploy", I'm getting the error below.
[deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: github.com (Net::SSH::AuthenticationFailed: gituser) connection failed for: github.com (Net::SSH::AuthenticationFailed: gituser)
Thanks in advance..
don't worry, you'll get it working in the end, I used to use the very same setup as yourself.... i.e. Dreamhost/Passenger/Capistrano/Git (and at one time, SVN) - it can be quite frustrating
Some things for you to do:
1) Read the following two articles by John Nunemaker # railstips.com - I used to refer to them every single time I had to setup a server on Dreamhost (the second one is the most important but the first link gives you some tips that are well worth following)
1.1) http://railstips.org/blog/archives/2008/11/23/gitn-your-shared-host-on/
1.2) http://railstips.org/blog/archives/2008/12/14/deploying-rails-on-dreamhost-with-passenger/
2) I think github is complaining about "gituser" - you do appear to set your username to "gituser" in your capfile - i would change that to your own name
3) you've got your domain down as github.com - again, this should be your own domain name and not github.... From what I recall..
4) start using heroku
good luck - hope this helps, let us know if it does or not....
cheers
You use your private url to clone your repository. Try with public clone URL
git://github.com/Myproject.git
i did to do sudo ln -s /opt/ruby/bin/packet_worker_runner /usr/bin/packet_worker_runner” and it solved the problem..
Thanks.
