安装erlang语言环境：

wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm 
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
yum -y install erlang --enablerepo=epel

测试是否安装成功，在控制台输入erl

erl //如果能进入erlang的shell交互环境则安装成功

安装RabbitMQ：

rpm --import http://www.rabbitmq.com/rabbitmq-signing-key-public.asc 
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.9/rabbitmq-server-3.6.9-1.el6.noarch.rpm 
yum -y install rabbitmq-server-3.6.9-1.el6.noarch.rpm

vim /etc/rabbitmq/rabbitmq-env.conf   //设置rabbitmq数据和log目录
RABBITMQ_MNESIA_DIR=/data/joygames/rabbitmq_repo
RABBITMQ_LOG_BASE=/data/joygames/rabbitmq_log

mkdir -p /data/rabbitmq_repo
mkdir -p /data/rabbitmq_log
service rabbitmq-server start  //开启服务
chkconfig rabbitmq-server on  //加入开机启动

rabbitmqctl status  //查看rabbitmq状态
Error: unable to connect to node 'rabbit@******': nodedown
DIAGNOSTICS
===========
attempted to contact: ['rabbit@******']
rabbit@******:
  * connected to epmd (port 4369) on ******
  * epmd reports: node 'rabbit' not running at all
                  no other nodes on ******
  * suggestion: start the node
current node details:
- node name: 'rabbitmq-cli-62@******'
- home dir: /var/lib/rabbitmq
- cookie hash: oO+s9WqqKA40C2mn7Fc2Qw==

发现服务没有起来，报出了上面一堆错误（*******为主机名）。

网上搜索很多说要更改erlang的cookie，将cookie hash的值覆盖/var/lib/rabbitmq/.erlang.cookie，经测试没有什么卵用。

还有说要修改/etc/hosts，再设置hostname的办法也一个鸟样。

解决方法：

1. 权限

   设置了rabbitmq的RABBITMQ_MNESIA_DIR和RABBITMQ_LOG_BASE，要多目录设置属组

   chown -R rabbitmq:rabbitmq /data/rabbitmq*

   service rabbitmq-server restart   //重启服务

   ps aux | grep rabbitmq     //查看服务进程是否起来

   

   服务已起来！

   再次执行rabbitmqctl status发现依然报刚才的错误

2. 设置hostname

   export HOSTNAME=主机名

   再次执行rabbitmqctl status

服务终于正常。

启用插件:

rabbitmq-plugins enable rabbitmq_management

创建用户并授权：

rabbitmqctl add_user admin admin
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
service rabbitmq-server restart
