我似乎无法让 Capistrano 与 AmazonRDS 完美配合。我到处寻找有关正确设置的任何信息,但没有找到任何信息。现在,当我时cap deploy
,该过程超时。
这是我的 deploy.rb:
set :deploy_to, "/opt/bitnami/apps/annarbortshirtcompany.com/cms/"
set :scm, :git
set :repository, "ssh://user@ec2-repository.compute-1.amazonaws.com/~/repo/cms.git"
set :deploy_via, :remote_cache
set :user, "user"
ssh_options[:keys] = [File.join(ENV["HOME"], "EC2", "admin.pem")]
ssh_options[:forward_agent] = true
set :branch, "master"
set :use_sudo, true
set :location, "ec2-webserver.compute-1.amazonaws.com"
role :web, location
role :app, location
role :db, "cmsinstance.c7r8frl6npxn.us-east-1.rds.amazonaws.com", :primary => true
# If you are using Passenger mod_rails uncomment this:
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
RDS 数据库实例的用户名与此处设置的 SSH 用户名不同,但在我的 database.yml 中定义。我认为这可能没有被 capistrano 阅读,但不知道如何做到这一点。
当我“上限部署”时:
ubuntu@ubuntu-VirtualBox:~/RailsApps/cms$ cap deploy
* executing `deploy'
* executing `deploy:update'
** transaction: start
* executing `deploy:update_code'
updating the cached checkout on all servers
executing locally: "git ls-remote ssh://user@ec2-repository.compute-1.amazonaws.com/~/repo/cms.git master"
command finished in 1590ms

为什么要“更新所有服务器上的缓存结帐”?此时甚至不需要数据库服务器。我很困惑如何解决这个问题。希望有人能指出我正确的方向!
