ruby-on-rails-4 - rails4-capistrano3 : How to start-stop-restart redis-server after deploy?

Question

我正在尝试为 redis 服务器添加一个启动-停止-重启的配方

通过ssh登录远程服务器我可以运行

 service redis-server restart

但添加到 deploy.rake

%w[start stop restart].each do |command|
  desc "#{command} Redis server."
    task command do
      on roles(:app) do
       execute "service redis-server #{command}"
      end
    end
end

重启时出错

 DEBUG [8410afb7] Command: service redis-server restart
 DEBUG [8410afb7]   Stopping redis-server:
 DEBUG [8410afb7]   redis-server.
 DEBUG [8410afb7]   Starting redis-server:
 DEBUG [8410afb7]   touch:
 DEBUG [8410afb7]   cannot touch ‘/var/run/redis/redis-server.pid’:  
 Permission denied

很明显/run 是 root:root...我该如何解决？我应该在我的主目录中安装 redis-server 吗？ (如果可能的话？)

谢谢你的建议

我应该写:

    execute :sudo, "service redis-server #{command}"

在我的 deploy.rake 配方中
