更换阿里云repo
http://mirrors.aliyun.com/repo/
下载
Centos-8.repo
查询最新的mq版本以及对应的erlang信息
参考url
https://www.rabbitmq.com/which-erlang.html
最新版本的mq为 3.8.14 对应的erlang为 23.X
配置yum源
参考 https://www.rabbitmq.com/install-rpm.html#package-cloud
A quick way to install is to use a Package Cloud-provided script. Package Cloud also can be used to install a recent Erlang version via yum.
1 参考 https://packagecloud.io/rabbitmq/rabbitmq-server/install#bash-rpm
curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash
# import the new PackageCloud key that will be used starting December 1st, 2018 (GMT)
rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
# import the old PackageCloud key that will be discontinued on December 1st, 2018 (GMT)
rpm --import https://packagecloud.io/gpg.key
rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
centos8 建repo文件
cd /etc/yum.repos.d
官网给的示例是
# In /etc/yum.repos.d/rabbitmq.repo
##
## Zero dependency Erlang
##
[rabbitmq_erlang]
name=rabbitmq_erlang
baseurl=https://packagecloud.io/rabbitmq/erlang/el/8/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
[rabbitmq_erlang-source]
name=rabbitmq_erlang-source
baseurl=https://packagecloud.io/rabbitmq/erlang/el/8/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
##
## RabbitMQ server
##
[rabbitmq_server]
name=rabbitmq_server
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/8/$basearch
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
[rabbitmq_server-source]
name=rabbitmq_server-source
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/8/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
因上一步script.rpm.sh自动已经创建了rabbitmq_server的repo文件，所以只需要建个erlang的repo文件就可以
vi rabbitmq_rabbitmq-erlang.repo
[rabbitmq_erlang]
name=rabbitmq_erlang
baseurl=https://packagecloud.io/rabbitmq/erlang/el/8/$basearch
repo_gpgcheck=1
gpgcheck=1
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
[rabbitmq_erlang-source]
name=rabbitmq_erlang-source
baseurl=https://packagecloud.io/rabbitmq/erlang/el/8/SRPMS
repo_gpgcheck=1
gpgcheck=0
enabled=1
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/erlang/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
安装
yum update -y
rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
如果把repo文件中的repo_gpgcheck设置为0，不校验的话不用上一步导入key
yum install erlang rabbitmq-server -y
启动服务
systemctl start rabbitmq-server
设置开机启动
systemctl enable rabbitmq-server
问题排错
启动失败

问题呢定位为主机名问题，原因为linux主机的名称是数字的原因造成此问题的
参考 https://blog.csdn.net/kang_tian/article/details/105719318
修改主机名
hostnamectl set-hostnam mq
修改后启动正常
Apr 1 16:17:49 192 systemd[1]: systemd-hostnamed.service: Succeeded.

rabbitmq 启动web界面管理 rabbitmq_management插件
rabbitmq-plugins enable rabbitmq_management
启动失败问题解决
[root@192 rabbitmq]# rabbitmq-plugins enable rabbitmq_management
{:query, :rabbit@mq, {:badrpc, :timeout}}
解决方案为 为主机名映射127.0.0.1
修改方法为
vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 mq
rabbitmq_management默认地址为：http://ip:15672或http://ip:55672
访问之前需要开放端口或者关闭防火墙
用户名默认有guest，密码为guest，可以使用命令增加其他用户并授权
./rabbitmqctl add_user ewallet 123456
./rabbitmqctl set_user_tags ewallet administrator
