管理 Resque 和 Redis 的多个实例

发布于 2025-01-06 03:05:38 字数 568 浏览 3 评论 0原文

我试图让上帝监视 Resque 的两个实例，一个用于生产，一个用于登台。

因此，我在系统启动时启动两个 Redis 实例：redis_6379 和 redis_6380。

然后我使用Daemontools来启动和监控God。

我的上帝脚本看起来像这样：

God.watch do |w|
  w.dir      = "#{rails_root}"
  w.name     = "resque-#{num}"
  w.group    = 'resque'
  w.interval = 30.seconds
  w.env      = {"QUEUE"=>"critical,high,low", "RAILS_ENV"=>rails_env}
  w.start    = "rake resque:work QUEUE='*' RAILS_ENV=#{rails_env}"
  ....
end

我不需要以某种方式将暂存和生产 resque 进程与特定的 redis 实例关联起来吗？

我正在逐渐将其拼凑起来，但我认为我遗漏了一个关键部分。

提前致谢

I am trying to have God monitor two instances of Resque, one for production and one for staging.

So I start two Redis instances on system boot: redis_6379 and redis_6380.

Then I'm using Daemontools to start and monitor God.

My God script looks something like this:

God.watch do |w|
  w.dir      = "#{rails_root}"
  w.name     = "resque-#{num}"
  w.group    = 'resque'
  w.interval = 30.seconds
  w.env      = {"QUEUE"=>"critical,high,low", "RAILS_ENV"=>rails_env}
  w.start    = "rake resque:work QUEUE='*' RAILS_ENV=#{rails_env}"
  ....
end

Don't I need to somehow associate the staging and production resque processes with particular redis instances?

I'm gradually piecing this together but I think I'm missing a key piece.

Thanks in advance

首先，您不需要在 w.start 中指定 QUEUE 和 RAILS_ENV，因为您已经在适当的位置指定了它们，w.env。

其次，此脚本在 rails_env 环境中运行 resque 的单个实例（无论其值是什么）。

我建议这样的事情：

%w(staging production).each do |rails_env|
  God.watch do |w|
    w.dir      = "#{rails_root}" # <= is this path the same for production and staging?
                                 # if not, change accordingly.
    w.name     = "resque-#{rails_env}"
    w.group    = 'resque'
    w.interval = 30.seconds
    w.env      = {"QUEUE"=>"critical,high,low", "RAILS_ENV"=>rails_env}
    w.start    = "rake resque:work"
    ....
  end
end

First, you don't need to specify QUEUE and RAILS_ENV in w.start since you already specified them in a proper place, w.env.

Second, this script runs a single instance of resque in a rails_env environment (whatever its value is).

I suggest something like this:

%w(staging production).each do |rails_env|
  God.watch do |w|
    w.dir      = "#{rails_root}" # <= is this path the same for production and staging?
                                 # if not, change accordingly.
    w.name     = "resque-#{rails_env}"
    w.group    = 'resque'
    w.interval = 30.seconds
    w.env      = {"QUEUE"=>"critical,high,low", "RAILS_ENV"=>rails_env}
    w.start    = "rake resque:work"
    ....
  end
end
