每运行RAILS_ENV多delayed_job的情况下， [英] run multi delayed_job instances per RAILS_ENV

问题描述

我的工作多RAILS_ENV

I'm working on a Rails app with multi RAILS_Env

env_name1:
  adapter:  mysql
  username: root
  password:
  host:     localhost
  database: db_name_1

env_name2:
  adapter:  mysql
  username: root
  password:
  host:     localhost
  database: db_name_2
...
..
.

和我使用的delayed_job（2.0.5）的插件管理asynchrone和背景的工作。

And i'm using delayed_job (2.0.5) plugin to manage asynchrone and background work.

我想每次启动RAILS_ENV多delayed_job的：

I would like start multi delayed_job per RAILS_ENV:

RAILS_ENV=env_name1 script/delayed_job start

RAILS_ENV=env_name2 script/delayed_job start
..

我注意到，我只能运行一个实例的delayed_job
对于第二个，我有这样的错误错误：已经有运行该程序的一个或多个实例（S）

I noticed that I can run only one delayed_job instance for the 2nd, I have this error "ERROR: there is already one or more instance(s) of the program running"

我的问题：岂不等于可以运行每RAILS_ENV多delayed_job的实例？
谢谢

My question : is't possible to run multi delayed_job instances per RAILS_ENV? Thanks

推荐答案

您可以有，只要它们有不同的进程名工作延迟运行多个实例。斯利姆一样在他的评论中提到，您可以使用-i标志为一个唯一的数字标识符添加到该进程名。于是命令将如下所示：

You can have multiple instance of delayed job running as long as they have different process names. Like Slim mentioned in his comment, you can use the -i flag to add a unique numerical identifier to the process name. So the commands would look like:

RAILS_ENV = env_name1脚本/ delayed_job的-i 1日开始

RAILS_ENV=env_name1 script/delayed_job -i 1 start

RAILS_ENV = env_name2脚本/ delayed_job的-i 2启动

RAILS_ENV=env_name2 script/delayed_job -i 2 start

这将创建两个单独的延迟作业实例，命名它们delayed_job.1和delayed_job.2

This would create two seperate delayed job instances, naming them delayed_job.1 and delayed_job.2

一个小问题，就是当你这样做，你也可以阻止他们时使用的相同的标志。省略-i 1或2 -i打电话时停，也不会阻止他们。作为延迟作业将不能找到正确的相应的过程停下来。

A gotcha is that when you do this you also have to use the same flags when stopping them. Omitting the -i 1 or -i 2 when calling stop, won't stop them. As delayed job won't be able to find the correct corresponding process to stop.
