CentOS7安装及搭建RabbitMQ集群

rabbitmq3.3.5

github提供的下载地址 https://github.com/rabbitmq/rabbitmq-server/releases/download/rabbitmq_v3_3_5/rabbitmq-server-3.3.5-1.noarch.rpm

注意：RabbitMQ需要erlang环境，Erlang和RabbitMQ对应版本（https://www.rabbitmq.com/which-erlang.html），注意有最大和最小版本要求。

建议erlang通过系统安装，用yum install erlang查看其版本，如我本机R14B-04.3.el6 (erlang.x86_64 0:R16B-03.18.el7)适合的MQ版本为3.5.x

yum -y update
yum -y install epel-release
sudo yum -y install lrzsz pcre pcre-devel openssl openssl-devel zlib zlib-devel axel telnet

yum install erlang -y
wget https://github.com/rabbitmq/rabbitmq-server/releases/download/rabbitmq_v3_3_5/rabbitmq-server-3.3.5-1.noarch.rpm
rpm -ivh rabbitmq-server-3.3.5-1.noarch.rpm

单机模式
-- 查看是否启动
ps -ef|grep rabbitmq
-- 执行添加用户命令
rabbitmqctl add_user root 1qaz@WSX
-- 执行设置权限命令
rabbitmqctl set_permissions -p / root ".*" ".*" ".*"
-- 执行设置角色命令
rabbitmqctl set_user_tags root administrator
-- 执行查看用户命令
rabbitmqctl list_users

-- 开启web页面

rabbitmq-plugins enable rabbitmq_management

-- 访问web页面默认IP:127.0.0.1,默认端口:5672,默认web管理端口：15672

http://127.0.0.1:15672/#/

出现错误：Error: unable to connect to node rabbit@iZj6cgwpv82s1jrkhgmwcaZ: nodedown
/sbin/service rabbitmq-server stop
/sbin/service rabbitmq-server start
rabbitmqctl status

下面的命令好像有问题

状态 rabbitmqctl status
停止 rabbitmqctl stop_app

启动 rabbitmqctl start_app

集群模式

-- 假设三台节点IP为
172.16.0.10
172.16.0.11
172.16.0.12

-- 配置本地 /etc/hosts（三个节点同步执行）
echo "
47.56.14.178 rabbitmq-node1
47.75.105.113 rabbitmq-node2
47.75.126.92 rabbitmq-node3" >> /etc/hosts

-- 加入配置文件（三个节点同步执行）

vim /etc/rabbitmq/rabbitmq.config
