Linux RabbitMQ单机与集群部署

1、下载rabbitMQ软件【这里以通用二进制包为准】

wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.8.6/rabbitmq-server-generic-unix-3.8.6.tar.xz

 2、RabbitMQ 对Erlang版本要求

到这里查看
https://www.rabbitmq.com/which-erlang.html

因为这里演示的版本是3.8.6，所以Erlang版本：21.3~23.X

3、下载Erlang

https://github.com/erlang/otp/archive/OTP-23.0.tar.gz

 4、Erlang安装

# 安装Erlang
~]# yum install mesa-libGL-devel mesa-libGLU-devel freeglut-devel gcc glibc-devel make ncurses-devel openssl-devel autoconf xmlto libtool automake -y
~]# tar xvf otp-OTP-23.0.tar.gz
~]# cd otp-OTP-23.0
otp-OTP-23.0]# ./otp_build autoconf
~]# ./otp_build autoconf && ./configure --prefix=/usr/local/erlang_23.0 && make && make install

# 配置Erlang环境变量
~]# vi /etc/profile
PATH=$PATH:/usr/local/erlang_23.0/bin/
~]# . /etc/profile

 5、安装RabbitMQ

# 解压rabbitMQ
~]# tar xvf rabbitmq-server-generic-unix-3.8.6.tar.xz -C /usr/local/

# 配置环境变量
~]# vi /etc/profile
PATH=$PATH:/usr/local/erlang_23.0/bin/:/usr/local/rabbitmq_server-3.8.6/sbin/
~]# . /etc/profile

# 命令启动rabbitMQ服务
~]# rabbitmq-server start    
Configuring logger redirection

# 检查端口是否开启成功  
~]# netstat -tunlp | grep beam

6、启用RabbitMQ Web管理的插件

 ~]# rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@localhost:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@localhost...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

set 3 plugins.
Offline change; changes will take effect at broker restart.

 7、编写rabbitMQ启动脚本

~]# mkdir /usr/local/rabbitmq_server-3.8.6/var/run
~]# mkdir /usr/local/rabbitmq_server-3.8.6/script
~]# vi /usr/local/rabbitmq_server-3.8.6/script/rabbitmq
~]# chmod 755 /usr/local/rabbitmq_server-3.8.6/script/rabbitmq

#!/bin/sh
# chkconfig: 2345 64 36
#
# rabbitmq-server RabbitMQ broker
#
# description: Enable AMQP service provided by RabbitMQ

case "$1" in

esac

exit $RETVAL

 8、利用脚本启动服务

~]# /usr/local/rabbitmq_server-3.8.6/script/rabbitmq start
~]# /usr/local/rabbitmq_server-3.8.6/script/rabbitmq stop

 9、配置Web管理用户

# 创建用户并且给用户设置管理员权限
~]# rabbitmqctl add_user admin admin
~]# rabbitmqctl set_user_tags admin administrator
~]# rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"  

~]# mkdir /etc/rabbitmq
~]# vi /usr/local/rabbitmq_server-3.8.6/etc/rabbitmq/rabbitmq.config 
[
{rabbit, [{tcp_listeners, [{"192.168.2.129",5672},{"127.0.0.1",5672}]}, {loopback_users, ["admin"]}]}
].
~]# /usr/local/rabbitmq_server-3.8.6/script/rabbitmq stop
~]# /usr/local/rabbitmq_server-3.8.6/script/rabbitmq start

 

 

10、登陆Web界面

 11、上面配置演示的是单机版，下面进行集群配置

 12、主机列表配置如下：

192.168.2.129 mq1 
192.168.2.229 mq2 

[root@mq1 ~]# cat /etc/hosts
192.168.2.129 mq1 
192.168.2.229 mq2 

[root@mq2 ~]# cat /etc/hosts
192.168.2.129 mq1 
192.168.2.229 mq2

 13、集群配置

# 选择mq1主机同步~/.erlang.cookie


#复制.erlang.cookie先停止服务
mq2 ~]# /usr/local/rabbitmq_server-3.8.6/script/rabbitmq stop

#找一台MQ主机作做集群参照节点，把参照节点.erlang.cookie同步其他节点上，保持.erlang.cookie数据一致就好
mq1 ~]# scp ~/.erlang.cookie root@mq2:~/.erlang.cookie

mq1 ~]# cat .erlang.cookie
PXYCFDSEHXSKBOKPGHAV

mq2 ~]# cat .erlang.cookie
PXYCFDSEHXSKBOKPGHAV

#检查集群状态
mq1 ~]# rabbitmqctl cluster_status
Cluster status of node rabbit@mq1 ...
Basics
...

mq2 ~]# rabbitmqctl cluster_status             
Cluster status of node rabbit@mq2 ...
Basics
...

#停止应用服务
mq1 ~]# rabbitmqctl stop_app

#将mq2增加到mq1集群中
mq1 ~]# rabbitmqctl join_cluster --ram rabbit@mq2
Clustering node rabbit@mq1 with rabbit@mq2

#再开启应用
mq1 ~]# rabbitmqctl start_app
Starting node rabbit@mq1 ...

 

 

 14、访问Web界面查看

 15、集群的移除

#先停止要删除的节点的服务
mq2 ~]# /usr/local/rabbitmq_server-3.8.6/script/rabbitmq stop
Stopping rabbitmq-server: 

#mq1节点删除集群中mq2
mq1 ~]# rabbitmqctl -n rabbit@mq1  forget_cluster_node rabbit@mq2
Removing node rabbit@mq2 from the cluster


#mq2节点恢复单机模式
mq2 ~]# rm -f .erlang.cookie
~]# rabbitmqctl -n rabbit@mq2  forget_cluster_node rabbit@mq1 
Removing node rabbit@mq1 from the cluster
~]# rabbitmqctl stop_app
Stopping rabbit application on node rabbit@mq2 ...
~]# rabbitmqctl reset
Resetting node rabbit@mq2 ...
~]# rabbitmqctl start_app
Starting node rabbit@mq2 ...

#恢复单机后，用户需要重新创建

 16、负载均衡

略，可以选择Haproxy,Nginx,LVS
