解决在Server 2008下突破Rabbitmq的socket限制数的方法【百科全说】

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!
