rails mina+puma 部署

出于安全考虑，不要使用 root 帐号运行 web 应用。这里新建一个专门用于部署的用户，例如 deploy 或者其它你喜欢的名字。运行以下命令创建用户：

# useradd -m -s /bin/bash deploy

将用户加入 sudo 群组，以便使用 sudo 命令：
# adduser deploy sudo
为 deploy 用户设置密码：
# passwd deploy
给Linux deploy用户 加入rvm 权限
usermod -a -G rvm deploy
退出当前 SSH 链接，用 deploy 帐号重新登陆。

##加入gem mina
mina init, 生成config/deploy.rb

require 'mina/rails'
require 'mina/git'
require 'mina/bundler'
require 'mina/rvm'
#服务器地址,是使用ssh的方式登录服务器
set :domain, 'deploy@yourIPServer'
#服务器中项目部署位置
set :deploy_to, '/home/deploy/api'
#git代码仓库
set :repository, 'git@XXX.git'
#git分支
set :branch, 'master'
set :rvm_path, '/usr/local/rvm/bin/rvm'
set :bundle_gemfile, "app/Gemfile"
# 中括号里的文件 会出现在服务器项目附录的shared文件夹中，这里加入了secrets.yml，环境密钥无需跟开发计算机一样
set :shared_paths, ['config/database.yml', 'log', 'config/secrets.yml']
set :rails_env, 'development'
task :environment do
  # 如果使用的是rbenv,这么设置,但需确保.rbenv-version(rbenv local 1.9.3-p374)已经存在于你的项目中
  invoke :'rvm:use[ruby-2.1.2@default]'
  # 如果使用rvm，可以这样加载一个RVM version@gemset
  # invoke :'rvm:use[ruby-1.9.3-p374@default]'
end
# 这个块里面的代码表示运行 mina setup时运行的命令
task :setup => :environment do
  # 在服务器项目目录的shared中创建log文件夹
  queue! %[mkdir -p "#{deploy_to}/#{shared_path}/log"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/log"]
  # 在服务器项目目录的shared中创建config文件夹 下同
  queue! %[mkdir -p "#{deploy_to}/#{shared_path}/config"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/config"]

  queue! %[touch "#{deploy_to}/#{shared_path}/config/database.yml"]
  queue! %[touch "#{deploy_to}/#{shared_path}/config/secrets.yml"]

  # puma.rb 配置puma必须得文件夹及文件
  queue! %[mkdir -p "#{deploy_to}/shared/tmp/pids"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/shared/tmp/pids"]

  queue! %[mkdir -p "#{deploy_to}/shared/tmp/sockets"]
  queue! %[chmod g+rx,u+rwx "#{deploy_to}/shared/tmp/sockets"]

  queue! %[touch "#{deploy_to}/shared/config/puma.rb"]
  queue  %[echo "-----> Be sure to edit 'shared/config/puma.rb'."]

  # tmp/sockets/puma.state
  queue! %[touch "#{deploy_to}/shared/tmp/sockets/puma.state"]
  queue  %[echo "-----> Be sure to edit 'shared/tmp/sockets/puma.state'."]

  # log/puma.stdout.log
  queue! %[touch "#{deploy_to}/shared/log/puma.stdout.log"]
  queue  %[echo "-----> Be sure to edit 'shared/log/puma.stdout.log'."]

  # log/puma.stdout.log
  queue! %[touch "#{deploy_to}/shared/log/puma.stderr.log"]
  queue  %[echo "-----> Be sure to edit 'shared/log/puma.stderr.log'."]

  queue  %[echo "-----> Be sure to edit '#{deploy_to}/#{shared_path}/config/database.yml'."]
end

#这个代码块表示运行 mina deploy时执行的命令
desc "Deploys the current version to the server."
task :deploy => :environment do
  to :before_hook do
  end
  deploy do
    #重新拉git服务器上的最新版本，即使没有改变
    invoke :'git:clone'

    #重新设定shared_path位置
    invoke :'deploy:link_shared_paths'
    invoke :'bundle:install'
    # invoke :'rails:db_migrate'
    invoke :'rails:assets_precompile'
    invoke :'deploy:cleanup'

    to :launch do
      queue "mkdir -p #{deploy_to}/#{current_path}/tmp/"
      # queue "chown -R www-data #{deploy_to}"
      queue "touch #{deploy_to}/#{current_path}/tmp/restart.txt"
    end
  end
end

这样一来mina的基本配置就完成，接下来只要将你开发环境的项目上传到git服务器，然后运行下面的命令就完成了

mina deploy

##puma配置

#!/usr/bin/env puma

#rails的运行环境
# environment 'production'
environment 'development'
threads 2, 64
workers 4

#项目名
app_name = "api"
#项目路径
application_path = "/home/deploy/#{app_name}"
#这里一定要配置为项目路径下地current
directory "#{application_path}/current"

#下面都是 puma的配置项
pidfile "#{application_path}/shared/tmp/pids/puma.pid"
state_path "#{application_path}/shared/tmp/sockets/puma.state"
stdout_redirect "#{application_path}/shared/log/puma.stdout.log", "#{application_path}/shared/log/puma.stderr.log"
bind "unix://#{application_path}/shared/tmp/sockets/#{app_name}.sock"
activate_control_app "unix://#{application_path}/shared/tmp/sockets/pumactl.sock"

#后台运行
daemonize true
on_restart do
  puts 'On restart...'
end
preload_app!

##启动puma
进入/yourprj/config
pumactl -F puma.rb start

##Nginx 配置

worker_processes  1;
	
    error_log  /var/log/nginx/error.log warn;
    pid        /var/run/nginx.pid;
	
    events {
        worker_connections  1024;
    }
	
    http {
        include       /etc/nginx/mime.types;
        default_type  application/octet-stream;
	
        log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                          '$status $body_bytes_sent "$http_referer" '
                          '"$http_user_agent" "$http_x_forwarded_for"';
	
        access_log  /var/log/nginx/access.log  main;
	
        sendfile        on;
        #tcp_nopush     on;
	
        keepalive_timeout  65;
	
        #gzip  on;
	
        #include /etc/nginx/conf.d/*.conf;
        upstream deploy {
                server unix:///var/www/ruby_sample/shared/tmp/sockets/ruby_sample.sock;
        }
	
        server {
            listen 80;
            server_name your.server.domain.ip; # change to match your URL
            root /var/www/ruby_sample/current/public; # I assume your app is located at this location
	
            location / {
                proxy_pass http://deploy; # match the name of upstream directive which is defined above
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            }
	
            location ~* ^/assets/ {
                # Per RFC2616 - 1 year maximum expiry
                expires 1y;
                add_header Cache-Control public;
                        # Some browsers still send conditional-GET requests if there's a
                # Last-Modified header or an ETag header even if they haven't
                # reached the expiry date sent in the Expires header.
                add_header Last-Modified "";
                add_header ETag "";
                break;
            }
     }
    }

接下里只需要重启nginx服务器，整个rails的环境就搭建完成了
nginx -s reload
