为什么 Capistrano 2 在 cap deploy:setup 成功后拒绝 cap deploy:cold ？
我正在尝试使用 Capistrano (2.5.19) 部署 Rails3 应用程序。我已成功运行：
cap deploy:setup
并且在服务器上创建了正确的目录。但是当我运行 capDeploy:cold 或 capdeploy 时，脚本会中途挂起。
shell$ cap deploy:cold
* executing `deploy:cold'
* executing `deploy:update'
** transaction: start
* executing `deploy:update_code'
executing locally: "git ls-remote [email protected]:test.git master"
* executing "git clone -q [email protected]:test.git /home/deployer/www/apps/test/releases/20101223162936 && cd /home/deployer/www/apps/test/releases/20101223162936 && git checkout -q -b deploy be3165b74d52540742873c125fb85d04e1ee3063 && git submodule -q init && git submodule -q sync && git submodule -q update && (echo be3165b74d52540742873c125fb85d04e1ee3063 > /home/deployer/www/apps/test/releases/20101223162936/REVISION)"
servers: ["server.foo.com"]
[server.foo.com] executing command
这是我的deploy.rb：
$:.unshift(File.expand_path("~/.rvm/lib"))
require 'rvm/capistrano'
set :rvm_ruby_string, 'jruby'
# main details
set :application, "test_sqlserver"
role :web, "server.foo.com"
role :app, "server.foo.com"
role :db, "server.foo.com", :primary => true
# server details
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
set :deploy_to, "/home/deployer/www/apps/#{application}"
set :deploy_via, :checkout
set :user, :deployer
set :use_sudo, false
# repo details
set :scm, :git
set :repository, "[email protected]:test.git"
set :branch, "master"
set :git_enable_submodules, 1
我相信我的文件权限设置正确
I am trying to deploy a Rails3 app with Capistrano (2.5.19). I have successfully run:
cap deploy:setup
and the correct directories were created on the server. But when I run cap deploy:cold or cap deploy the script hangs halfway through.
shell$ cap deploy:cold
* executing `deploy:cold'
* executing `deploy:update'
** transaction: start
* executing `deploy:update_code'
executing locally: "git ls-remote [email protected]:test.git master"
* executing "git clone -q [email protected]:test.git /home/deployer/www/apps/test/releases/20101223162936 && cd /home/deployer/www/apps/test/releases/20101223162936 && git checkout -q -b deploy be3165b74d52540742873c125fb85d04e1ee3063 && git submodule -q init && git submodule -q sync && git submodule -q update && (echo be3165b74d52540742873c125fb85d04e1ee3063 > /home/deployer/www/apps/test/releases/20101223162936/REVISION)"
servers: ["server.foo.com"]
[server.foo.com] executing command
Here is my deploy.rb:
$:.unshift(File.expand_path("~/.rvm/lib"))
require 'rvm/capistrano'
set :rvm_ruby_string, 'jruby'
# main details
set :application, "test_sqlserver"
role :web, "server.foo.com"
role :app, "server.foo.com"
role :db, "server.foo.com", :primary => true
# server details
default_run_options[:pty] = true
ssh_options[:forward_agent] = true
set :deploy_to, "/home/deployer/www/apps/#{application}"
set :deploy_via, :checkout
set :user, :deployer
set :use_sudo, false
# repo details
set :scm, :git
set :repository, "[email protected]:test.git"
set :branch, "master"
set :git_enable_submodules, 1
I believe my file permissions are setup correctly

至少从 1.6.5 开始，JRuby 中似乎存在一个错误 - 请参阅 SSH 代理转发不起作用使用 jRuby（这会让 capistrano ssh 部署失败）
显然，一种“解决方法”是不使用 SSH 代理转发，尽管这可能不可接受。如果您希望更快地注意到并解决该问题（我知道我是这样做的），查看该问题可能会有所帮助。
There appears to be a bug in JRuby since at least 1.6.5 -- see SSH Agent forwarding does not work with jRuby (which lets capistrano ssh-deployments fail)
Apparently one "workaround" is to not use SSH agent forwarding, though that may not be acceptable. If you want the issue noticed and fixed faster (I know I do), watching the issue might help.
看起来您无法在 jruby 下运行 Capistrano，因为 jruby-openssl 不支持 Capistrano 底层的
Net:SSH。http://jruby-extras.rubyforge.org/jruby-openssl/
Looks like you can't run Capistrano under jruby, as jruby-openssl doesn't support
Net:SSHwhich underlies Capistrano.http://jruby-extras.rubyforge.org/jruby-openssl/
