Rails后台任务Sidekiq的使用

使用sidekiq需先安装redis

1. 新建或者进入存放redis的目录，下载，解压和安装：

   $ wget http://download.redis.io/releases/redis-2.8.11.tar.gz
   $ tar xzf redis-2.8.11.tar.gz
   $ cd redis-2.8.11
   $ make
   $ sudo make install   #这时Redis的可执行文件被放到了/usr/local/bin

2. 下载配置文件和init启动脚本：

   $ wget https://github.com/ijonas/dotfiles/raw/master/etc/init.d/redis-server
   $ wget https://github.com/ijonas/dotfiles/raw/master/etc/redis.conf
   $ sudo mv redis-server /etc/init.d/redis-server
   $ sudo chmod +x /etc/init.d/redis-server
   $ sudo mv redis.conf /etc/redis.conf

3. 初始化用户和日志路径
   第一次启动Redis前，建议为Redis单独建立一个用户，并新建data和日志文件夹

   $ sudo useradd redis
   $ sudo mkdir -p /var/lib/redis
   $ sudo mkdir -p /var/log/redis
   $ sudo chown redis.redis /var/lib/redis
   $ sudo chown redis.redis /var/log/redis

4. 进设置开机自动启动，关机自动关闭

   $ sudo update-rc.d redis-server defaults

5. 启动Redis

   $ sudo /etc/init.d/redis-server start

rails使用sidekiq

1. 添加gem包，并bundle install

   # 后台任务
   gem 'sidekiq'
   # 和sidekiq的monitor相关
   gem 'slim'
   gem 'sinatra', '>= 1.3.0', :require => nil

2. 创建Worker: app/workers/your_worker.rb

   class YourWorker
     include Sidekiq::Worker
     def perform(name)
       puts 'Doing hard work'
     end
   end

3. 在controller或者model中调用YourWorker

   YourWorker.perform_async('yggc')

4. 在config/routes.rb中添加监控页面路由，访问/sidekiq

   require 'sidekiq/web'
   # 后台任务页面
   mount Sidekiq::Web => '/sidekiq'

5. 在config/中添加sidekiq.yml

6. 启动服务

   $ bundle exec sidekiq -C config/sidekiq.yml 调试启动方式
   $ bundle exec sidekiq -C config/sidekiq.yml -d 后台启动方式
   $ bundle exec sidekiq -C config/sidekiq.yml -d -e production 指定环境启动

7. 停止服务

   bundle exec sidekiqctl stop tmp/pids/sidekiq.pid
