我們利用Rabbitmq進(jìn)行各類業(yè)務(wù)系統(tǒng)(如SAP、OA、EHR、KMS、訪客系統(tǒng)、AD等)的集成和接口，已有很長一段時(shí)間了，初步建立了企業(yè)服務(wù)總線(ESB)。隨著新業(yè)務(wù)系統(tǒng)的不斷接入到ESB中，在實(shí)踐中也發(fā)現(xiàn)了一些問題并總結(jié)了一些經(jīng)驗(yàn)，下文主要介紹如何在windows下突破 Rabbitmq的socket限制數(shù)，以便為需要使用的同學(xué)分享一些實(shí)際經(jīng)驗(yàn)，后續(xù)將陸續(xù)分享一些技術(shù)經(jīng)驗(yàn)。

1、 如何在windows下擴(kuò)展sockets數(shù)量，提高吞吐量?
(A)、需要在windows系統(tǒng)環(huán)境變量中設(shè)置erlang的ERL_MAX_PORTS
(B)重啟RabbitMQ服務(wù)才能正式生效
(C)擴(kuò)展后的最終效果如下：
結(jié)語:通過以上的步驟，就可以解決啦!
