rails 中使用Capistrano部署

git地址： https://github.com/capistrano/capistrano

在Gemfile中添加Capistrano和其它用到的插件：

group :development do
　　gem 'capistrano'
　　gem 'capistrano-rails'
　　gem 'capistrano-rvm'
　　gem 'capistrano-sidekiq', require: false
　　gem 'capistrano3-puma'
end

安装bundle install

初始化：cap install

capfile中的设置可以根据自己的设置来选择

# Load DSL and set up stages
require "capistrano/setup"

# Include default deployment tasks
require "capistrano/deploy"

# Load the SCM plugin appropriate to your project:
#
# require "capistrano/scm/hg"
# install_plugin Capistrano::SCM::Hg
# or
# require "capistrano/scm/svn"
# install_plugin Capistrano::SCM::Svn
# or
require "capistrano/scm/git"
install_plugin Capistrano::SCM::Git

# Include tasks from other gems included in your Gemfile
#
# For documentation on these, see for example:
#
# https://github.com/capistrano/rvm
# https://github.com/capistrano/rbenv
# https://github.com/capistrano/chruby
# https://github.com/capistrano/bundler
# https://github.com/capistrano/rails
# https://github.com/capistrano/passenger
#

require "capistrano/rvm"
# require "capistrano/rbenv"
# require "capistrano/chruby"
require "capistrano/bundler"
require "capistrano/rails/assets"
require 'capistrano/sidekiq'
require 'capistrano/puma'
install_plugin Capistrano::Puma, load_hooks: false
require "capistrano/rails/migrations"
# require "capistrano/passenger"

# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

配置好stage  ：不同的分支不同的设置  staging  、production等

发布命令： cap staging deploy

备注：如果在git中没有上传Gemfile.lock 一定要上传  不然一直会报错

然后就可以在服务器看到目录
