wget -c http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
yum install erlang
rpm -Uvh  rabbitmq-server-3.4.3-1.noarch.rpm
在命令敲rabbitmq-server。不会报command not found就OK了。
/etc/init.d/rabbitmq-server start

如果启动报：node with name "rabbit" already running on "mail"
vim /etc/rabbitmq/rabbitmq-env.conf
NODENAME=rabbit@localhost

NODE_IP_ADDRESS=127.0.0.1

--这两天新装机器，发现上述链接失效了。下面使用下载版erl安装，亲测，如下：

从https://www.erlang-solutions.com/resources/download.html下载R16B03版本的erlang。

rpm ivh esl-erlang_16.b.3-1~centos~6_amd64.rpm

export ERL_HOME=/usr/local/erlang

PATH=$RABBITMQ_HOME/sbin:$ERL_HOME/bin:$JAVA_HOME/bin:$PATH:$HOME/bin

安装完成后，输入erl看是否跳出交互界面，如下：

[root@dev-server local]# erl
Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.4  (abort with ^G)
1>

为了最方便不易出错，使用unix-generic.tar.gz通用版，不用rpm和源码。

从http://www.rabbitmq.com/releases/rabbitmq-server/v3.5.7/下载rabbitmq-server-generic-unix-3.5.7.tar.gz

tar xzvf rabbitmq-server-generic-unix-3.5.7.tar.gz

ln -s rabbitmq_server-3.5.7/ rabbitmq

export RABBITMQ_HOME=/usr/local/rabbitmq

启动rabbitmq

[root@dev-server ~]# rabbitmq-server

启用控制台

[root@dev-server ~]# rabbitmq-plugins enable rabbitmq_management
The following plugins have been enabled:
  mochiweb
  webmachine
  rabbitmq_web_dispatch
  amqp_client
  rabbitmq_management_agent
  rabbitmq_management

Applying plugin configuration to rabbit@dev-server... started 6 plugins.

在某些情况下，可能会出现如下错误：

Error: The following plugins could not be found:
  rabbitmq_management

此时是因为rabbitmq查找插件的路径不正确所致。可按照如下方式解决：

mkdir /etc/rabbitmq

vi /etc/rabbitmq/rabbitmq-env.conf    #这个是rabbitmq环境变量的配置文件,这个文件的位置是确定和不能改变的，位于：/etc/rabbitmq或$RABBITMQ_HOME/etc/rabbitmq目录下（视具体的安装方式而定）,具体可参考http://www.rabbitmq.com/configure.html。

增加如下配置项：

RABBITMQ_MNESIA_BASE=/usr/local/rabbitmq/data
RABBITMQ_LOG_BASE=/usr/local/rabbitmq/log
RABBITMQ_PLUGINS_DIR=/usr/local/rabbitmq/plugins

重启rabbitmq，问题解决。

PS：rabbitmq的标准配置文件是rabbitmq.config,它既有默认的目录，也可以在rabbitmq-env.conf文件中配置。,具体可参考http://www.rabbitmq.com/configure.html。

rabbitmq对erlang的版本要求如下：

注：如果windows下报 node with name "rabbit" already running on XXX，则先执行rabbitmqctl.bat stop，再启动即可。
