解决在Server 2008下突破Rabbitmq的socket限制数的方法

　　我们利用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。,　　第一、 RabbitMQ_Limits文档说明,　　Status of node rabbit@MYSERVER ...,　　[{pid,6604},,　　{running_applications,,　　[{rabbitmq_management,"RabbitMQ Management Console","2.8.2"},,　　{xmerl,"XML parser","1.3"},,　　{rabbitmq_management_agent,"RabbitMQ Management Agent","2.8.2"},,　　{amqp_client,"RabbitMQ AMQP Client","2.8.2"},,　　{rabbit,"RabbitMQ","2.8.2"},,　　{os_mon,"CPO CXC 138 46","2.2.8"},,　　{sasl,"SASL CXC 138 11","2.2"},,　　{rabbitmq_mochiweb,"RabbitMQ Mochiweb Embedding","2.8.2"},,　　{webmachine,"webmachine","1.7.0-rmq2.8.2-hg"},,　　{mochiweb,"MochiMedia Web Server","1.3-rmq2.8.2-git"},,　　{inets,"INETS CXC 138 49","5.8"},,　　{mnesia,"MNESIA CXC 138 12","4.6"},,　　{stdlib,"ERTS CXC 138 10","1.18"},,　　{kernel,"ERTS CXC 138 10","2.15"}]},,　　{os,{win32,nt}},,　　{erlang_version,"Erlang R15B (erts-5.9) [smp:4:4] [async-threads:30]n"},,　　{memory,,　　[{total,22807872},,　　{processes,8644230},,　　{processes_used,8644210},,　　{system,14163642},,　　{atom,495069},,　　{atom_used,485263},,　　{binary,665136},,　　{code,9611946},,　　{ets,877468}]},,　　{vm_memory_high_watermark,0.20002174609205853},,　　{vm_memory_limit,858993459},,　　{disk_free_limit,4294500352},,　　{disk_free,26035458048},,　　{file_descriptors,,　　[{total_limit,924},,　　{total_used,24},,　　{sockets_limit,829}, 默认的限制sockets数为829,　　{sockets_used,22}]},,　　{processes,[{limit,1048576},{used,388}]},,　　{run_queue,0},,　　{uptime,72329}],　　1、 如何在windows下扩展sockets数量，提高吞吐量?,　　(A)、需要在windows系统环境变量中设置erlang的ERL_MAX_PORTS,　　(B)重启RabbitMQ服务才能正式生效,　　(C)扩展后的最终效果如下：, ,　　结语:通过以上的步骤，就可以解决啦!,
