浅析RabbitMQ 集群

1.1 基础安装

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	3.5.2-1

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

http://www.rabbitmq.com/releases/rabbitmq-server/v3.5.2/rabbitmq-server-3.5.2-1.noarch.rpm

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

1.2 MQ Master配置

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, <<"autohome">>},

{default_pass, <<"S7!CUy3lZ5;_[K">>},

{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

1.Service rabbitmq-server restart

2.chkconfig rabbitmq on

1.3 MQ 群集配置 (Mater 操作)

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,[]}]

1.4 MQ 后续工作

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
