浅析RabbitMQ 集群

角色

IP地址

主机名

MQ版本

Master

192.168.103.83

rabbit-jxs-10383

3.5.2-1

slave

192.168.103.84

rabbit-jxs-10384

1)  配置yum 源 (Master/slave 同时配置)          

    yum -y install epel-release

1)    安装erlang (Master/slave 同时配置)

       Yum –y install erlang

2)    安装RabbitMQ (Master/slave 同时配置)

rpm –vih rababitmq-server-3.5.2-1.noarch.rpm

3)    修改主机名

a)      Hostname rabbit-jxs-10383 #slave

b)     Vim /etc/sysconfig/network

 Hostname= rabbit-jxs-10383

c)      Vim /etc/hosts (Master/slave 同时配置)

 192.168.103.83 rabbit-jxs-10383

 192.168.103.84 rabbit-jxs-10384

d)     MQ WEB 配置

 [rabbitmq_management,rabbitmq_management_agent].

e)     MQ 服务配置

[root@rabbit-jxs-10383 rabbitmq]# cat rabbitmq.conf

% This file managed by Puppet

% Template Path: rabbitmq/templates/rabbitmq.config

[

  {rabbit, [

    {default_user, <<"guest">>},

    {default_pass, <<"guest>>},

    {tcp_listeners,[5672]},

    {cluster_partition_handling, ignore}

  ]},

  {kernel, [

  ]}

].

% EOF

f)      MQ 环境变量配置

[root@rabbit-jxs-10383 rabbitmq]# cat rabbitmq-env.conf

RABBITMQ_NODE_PORT=5672

MNESIA_BASE=/data/rabbitmq/data

LOG_BASE=/data/rabbitmq/log

g)     MQ 创建目录

  Mkdir /data/rabitmq/data –p

  Mkdir /data/rabbitmq/log –p

  Chown rabbitmq:rabbitmq /data/rabbitmq –R

h)     MQ启动服务

  Service rabbitmq-serve restart

  Chkconfig rabbitmq-server on

i)       MQ 端口监听

[root@rabbit-jxs-10383 rabbitmq]# netstat -tnpl |grep 567

tcp        0      0 0.0.0.0:5672                0.0.0.0:*                   LISTEN      10020/beam.smp     

tcp        0      0 0.0.0.0:25672               0.0.0.0:*                   LISTEN      10020/beam.smp     

tcp        0      0 0.0.0.0:15672               0.0.0.0:*                   LISTEN      10020/beam.smp     

[root@rabbit-jxs-10383 rabbitmq]#

4)    MQ slave 服务配置

a)      同步Master RabbitMQ 文件配置

  Scp –p 30000 192.168.103.83:/etc/rabbitmq/* /etc/rabbitmq/

  Chown rabbitmq:rabbitmq –R /etc/rabbitmq/ 

b)     MQ 创建工作目录

  Mkdir /data/rabbitmq/data –p

  Mkdir /data/rabbitmq/log –p

  Chown rabbitmq:rabbitmq –R /data/rabbitmq

c)      同步Master Rabbitmq .erlang.cookie

  Scp –p 30000 192.168.103.83:/var/lib/rabbitmq/.erlang.cookie ./var/lib/rabbitmq/

 Chown rabbitmq:rabbitmq /var/lib/rabbitmq

d)     启动MQ slave  服务

Service rabbitmq-server restart

chkconfig rabbitmq on

e)     停止Master MQ

rabbitmqctl stop_app

f)      清空Master MQ信息

 rabbitmqctl reset

g)     加入10384 到MQ集群中

 rabbitmqctl  join_cluster rabbit@rabbit-jxs-10384

h)     启动MQmaster 服务

rabbitmqctl start_app

i)       查看状态

[root@rabbit-jxs-10383 ~]# rabbitmqctl cluster_status

Cluster status of node 'rabbit@rabbit-jxs-10383' ...

[{nodes,[{disc,['rabbit@rabbit-jxs-10383','rabbit@rabbit-jxs-10384']}]},

 {running_nodes,['rabbit@rabbit-jxs-10384','rabbit@rabbit-jxs-10383']},

 {cluster_name,<<"rabbit@rabbit-jxs-10383">>},

      {partitions,[]}]

1） 创建Rabbit 管理用户

a)      rabbitmqctl add_user admin admin

2） 赋予用户权限

a)      rabbitmqctl set_user_tags admin administrator

3） MQ 镜像实现

a)      rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}'

4） 完成MQ配置

a)      http://192.168.103.84:15672
