CentOS7通过yum安装RabbitMQ3.9.10

记录一次rabbitmq安装过程，供自己及有需要的人参考。
前言：RabbitMQ不同版本对Erlang版本有要求（版本对比参考：Erlang版本要求），也对操作系统版本有要求（暂时没在官网找到对应关系），几经努力成功安装rabbitmq3.9.10版本，主要是参考了官网（官网位置）。
环境：腾讯云轻量级云服务器，CentOS7
查看系统版本：cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)

yum源配置文件夹（/etc/yum.repos.d)下添加rabbitmq.repo，文件内容如下：

# In /etc/yum.repos.d/rabbitmq.repo

##
## Zero dependency Erlang

猜测：使用这个yum之后，可以解决Erlang版本和操作系统版本问题。

#更新yum源
yum update -y

#install these dependencies from standard OS repositories
yum install socat logrotate -y

#安装erlang和rabbitmq
yum install erlang rabbitmq-server -y

#查看Erlang
erl -v
Erlang/OTP 24 [erts-12.1.5] [source] [64-bit] [smp:2:2] [ds:2:2:10] [async-threads:1]
Eshell V12.1.5  (abort with ^G)

#查看rabbitmq，可能要启动后才能使用rabbitmqctl
rabbitmqctl version
3.9.10

#启动
systemctl start rabbitmq-server

#查看状态
systemctl status rabbitmq-server

需要开发5672即15672端口，15672端口为管理界面使用

#添加5672及15672
firewall-cmd --permanent --zone=public --add-port=5672/tcp
firewall-cmd --permanent --zone=public --add-port=15672/tcp

#重新加载防火墙数据
firewall-cmd --reload

sudo /sbin/rabbitmq-plugins enable rabbitmq_management

#查询安装默认的用户（一般有一个guest 用户和一个administrator管理员用户）
rabbitmqctl list_users

#其中admin 是用户名，123456是密码
rabbitmqctl add_user admin 123456

#通过命令给用户增加角色权限 
rabbitmqctl set_user_tags admin administrator

#给用户增加所有访问权限 
rabbitmqctl  set_permissions -p "/" admin '.*' '.*' '.*'

到此rabbitmq安装完成，页面URL：http://ip:15672/。
