想边自己写ruby代码，边部署随时能够到处查看，heroku域名又不友好，速度在国内又慢。于是乎想起来capistrano,于是学起 ...
capistrano 一点入门认知

# Deploy in Gemfile
gem 'capistrano', '~> 3.2.0'
完毕安装即可。并生成capfile等即可了 ...
$bundle exec cap install
具体配置：
$vim config/deploy/production.rb
## content
11 server 'qzi.me', roles: [:demo], port:1234, user: 'qzi'
12 task :uptime do |host|
13 on roles(:demo), in: :parallel do
14 uptime = capture(:uptime)
15 hostname = capture(:hostname)
16 puts "#{hostname} reports: #{uptime}"
17 end
18 end
$ cap production uptime
更优写法：
$vim config/deploy/production.rb
server 'qzi.me', roles: [:demo], port: 1234, user: ‘qzi’
$ vim lib/capistrano/tasks/test.rake
desc "check the uptime on the host"
task :uptime do |host|
on roles(:demo), in: :parallel do
uptime = capture(:uptime)
hostname = capture(:hostname)
puts "#{hostname} reports: #{uptime}"
end
end
$cap -T # 能够查到你新增加的命令了

还有就是rails 项目怎么部署解释起来得另外去学，比方passenger, unicorn 等都不会非常难;
当然自己要有主机, 域名之类的;
临时先这样吧。主机登陆和操作命令都已经点到，以后把笔记再整理一通过与一些撞在了一起 ...
