如何在windows Server 2008 R2下突破Rabbitmq的socket限制数

利用Rabbitmq进行各类业务系统（如SAP、OA、EHR、KMS、访客系统、AD等）的集成和接口，已有很长一段时间了，初步建立了企业服务总线（ESB）。随着新业务系统的不断接入到ESB中，在实践中也发现了一些问题并总结了一些经验，下文主要介绍如何在windows下突破Rabbitmq的socket限制数，以便为需要使用的同学分享一些实际经验，后续将陆续分享一些技术经验。

1、 RabbitMQ_Limits文档说明

1、 如何在windows下扩展sockets数量，提高吞吐量？

（1）、需要在windows系统环境变量中设置erlang的ERL_MAX_PORTS

    

（2）重启RabbitMQ服务才能正式生效

 

（3）扩展后的最终效果如下：
