RabbitMQ安装和测试小记

操作系统CentOS x86_64 5.4

 

安装Erlang

可以到www.erlang.org去下载最新的源码，编译安装。

不过RabbitMQ的官方文档建议使用yum安装。

 

EPEL是啥？

参见http://fedoraproject.org/wiki/EPEL/FAQ#howtouse

 

安装步骤：

 

wget http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm
 

rpm -Uvh epel-release-5-3.noarch.rpm

 

yum install erlang

 

 

安装RabbitMQ

到 http://www.rabbitmq.com/server.html 下载

rabbitmq-server-1.7.2-1.x86_64.rpm

 

 

然后

 

rpm -ivh rabbitmq-server-1.7.2-1.x86_64.rpm

 

 

运行RabbitMQ

 

/etc/init.d/rabbitmq-server start

 

 

注意

RabbitMQ使用了5672端口，修改iptables把5672端口打开。

 

测试

在官网下载java的客户端rabbitmq-java-client-bin-1.7.2.tar.gz
