Mina 部署 Rails 应用程序,服务器选择 unicorn

有过自己尝试 capistrano 成功的案例,但是还是想尝试下 mina,确实配置少,速度快,但是 unicorn 貌似有点问题

此处快速略过 mina 基础姿势

Gemfile 添加

  • gem 'mina'
  • gem 'mina-sidekiq',:require => false
  • gem 'mina-unicorn', :require => false

bundle 安装

执行mina init,生成 config/deploy.rb,我的配置如下:

require 'mina/bundler'
require 'mina/rails'
require 'mina/git'
require 'mina/rvm'    # for rvm support. (https://rvm.io)  
require 'mina/unicorn'
require "mina_sidekiq/tasks"

set :application_name, 'baller'
set :domain, 'xx.xx.xx.xx'
set :deploy_to, '/home/chenxi/xxx_app'
set :user, 'chenxi'
set :port, '22'
set :forward_agent, true


set :repository, '项目xxx.git'
set :branch, 'master'

set :sidekiq_pid, "#{fetch(:deploy_to)}/shared/tmp/pids/sidekiq.pid"
set :unicorn_pid, "#{fetch(:deploy_to)}/shared/tmp/pids/unicorn.pid"
set :unicorn_env, 'production'


set :rvm_use_path, '/usr/local/rvm/scripts/rvm'


task :remote_environment do
  invoke :'rvm:use', 'ruby-2.2.1@baller4116'
end

set :shared_dirs, fetch(:shared_dirs, []).push('public/assets', 'public/system', 'public/uploads')
set :shared_files, fetch(:shared_files, []).push('config/database.yml', 'config/secrets.yml','config/config.yml','vendor/bundle')

task :setup do

  ['log', 'config', 'public/upload','public/system','tmp/pids', 'tmp/sockets'].each do |dir|
    command %{mkdir -p "#{fetch(:deploy_to)}/shared/#{dir}"}
    command %{chmod g+rx,u+rwx "#{fetch(:deploy_to)}/shared/#{dir}"}
  end

  ['config/database.yml', 'config/secrets.yml', 'config/config.yml','log/unicorn.log','log/unicorn_error.log'].each do |file|
    command %{touch "#{fetch(:deploy_to)}/shared/#{file}"}
    comment %{Be sure to edit 'shared/#{file}'.}
  end

end

desc "Deploys the current version to the server."
task :deploy  do
  # to :before_hook do
  #   # Put things to run locally before ssh
  # end
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    on :launch do
      # sidekiq stop accepting new workers
      invoke :'sidekiq:quiet'
      invoke :'sidekiq:restart'
      invoke :'unicorn:restart'
    end
  end
end

执行mina setup 生成相关目录依赖等,此处不多说

执行mina deploy部署,此处也不多说哈,如我所预期,bundle, 静态资源文件编译,migratie 等等都正常通过了,Unicorn 也成功启动了😆 😆 😆,以下是 unicorn.rb

app_path = File.expand_path( File.join(File.dirname(__FILE__), '..', '..'))
worker_processes   1
timeout            180
listen 3000, tcp_nopush: false
listen             "#{app_path}/shared/tmp/sockets/unicorn.sock"
pid                "#{app_path}/shared/tmp/pids/unicorn.pid"
stderr_path        "#{app_path}/shared/log/unicorn_error.log"
stdout_path        "#{app_path}/shared/log/unicorn.log"

before_fork do |server, worker|
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.connection.disconnect!
  end

  old_pid = "#{server.config[:pid]}.oldbin"
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
      # someone else did our job for us
    end
  end
end

after_fork do |server, worker|
  if defined?(ActiveRecord::Base)
    ActiveRecord::Base.establish_connection
  end
end

before_exec do |server|
  ENV["BUNDLE_GEMFILE"] = "#{app_path}/current/Gemfile"
end

查看 unicorn 确实已经起来了,如下:

unicorn 进程没问题

unicorn 配置 listen 的 3000 没问题

unicorn_error.log 显示无异常

但是!当我访问 xx.xx.xx.xxx:3000 一直呈现该页无法显示,查看 unicorn_error.log 显示无异常😰😰😰

肯定是一个很小的问题...被我忽略了,哈哈哈,请教大神围观分析!!😢😢😢

服务器上 curl 一下本地端口能不能访问?云服务有没有安全组设置?

就是安全组...大意了😅 3Q
