Server 2008下突破Rabbitmq的socket限制數

   利用Rabbitmq進行各類業務系統(如SAP、OA、EHR、KMS、訪客系統、AD等)的集成和接口,已有很長一段時間了,初步建立了企業服務總線(ESB)。隨著新業務系統的不斷接入到ESB中,在實踐中也發現了一些問題並總結了一些經驗,下文主要介紹如何在windows下突破Rabbitmq的socket限制數,以便為需要使用的同學分享一些實際經驗,後續將陸續分享一些技術經驗。

  1、 RabbitMQ_Limits文檔說明

  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}, 默認的限制sockets數為829

  {sockets_used,22}]},

  {processes,[{limit,1048576},{used,388}]},

  {run_queue,0},

  {uptime,72329}]

  1、 如何在windows下擴展sockets數量,提高吞吐量?

  (1)、需要在windows系統環境變量中設置erlang的ERL_MAX_PORTS

  (2)重啟RabbitMQ服務才能正式生效

  (3)擴展後的最終效果如下:
