在CentOS 8上安装RabbitMQ服务器
RabbitMQ是基于AMQP协议构建的开源消息代理软件。在本指南中，您将看到如何在CentOS 8上安装RabbitMQ服务器。
目录
什么是RabbitMQ ？
RabbitMQ是一种开源消息代理软件（有时称为面向消息的中间件），最初实现了高级消息队列协议（AMQP），并已通过插件体系结构进行了扩展，以支持面向流文本的消息协议（STOMP）。，MQ遥测传输（MQTT）和其他协议。
RabbitMQ服务器程序是用Erlang编程语言编写的，并建立在Open Telecom Platform框架上，用于集群和故障转移。与代理交互的客户端库适用于所有主要编程语言，包括Java，Erlang和.NET Framework。（来源：维基百科）
RabbitMQ源代码可在RabbitMQ GitHub Repository上获得，并根据Mozilla Public License分发。

第一步：更新您的Linux服务器
使用SSH客户端与连接rabbitmq.lianglab.cn服务器为Linux的根用户。
使用dnf命令将Linux服务器中的软件包更新为最新的稳定版本。
[root@centos8 ~]# hostnamectl set-hostname rabbitmq.lianglab.cn [root@rabbitmq ~]# chattr -ai /boot/grub2/grub.cfg [root@rabbitmq ~]# dnf update -y -----------------------------------------省略---------------------------------------------------------- (104/106): spice-server-0.14.2-1.el8_2.1.x86_64.rpm 12 MB/s | 404 kB 00:00 (105/106): unbound-libs-1.7.3-11.el8_2.x86_64.rpm 14 MB/s | 499 kB 00:00 (106/106): firefox-78.4.0-1.el8_2.x86_64.rpm 50 MB/s | 105 MB 00:02 -----------------------------------------省略---------------------------------------------------------- Installed: kernel-4.18.0-193.28.1.el8_2.x86_64 kernel-core-4.18.0-193.28.1.el8_2.x86_64 kernel-modules-4.18.0-193.28.1.el8_2.x86_64 Complete! [root@rabbitmq ~]# 在此处检查Linux操作系统和使用中的虚拟机的内核版本。
[root@rabbitmq ~]# cat /etc/redhat-release CentOS Linux release 8.2.2004 (Core) [root@rabbitmq ~]# uname -a Linux rabbitmq.lianglab.cn 4.18.0-193.el8.x86_64 #1 SMP Fri May 8 10:59:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux [root@rabbitmq ~]# reboot 第二步：Linux服务器上安装EPEL Yum存储库
RabbitMQ服务器所需的某些软件包可在EPEL（企业Linux的额外软件包） yum存储库中获得。
因此，在安装RabbitMQ之前，您需要在Linux服务器上启用/安装EPEL yum存储库。
[root@rabbitmq yum.repos.d]# dnf install -y epel-release CentOS-8 - Base - mirrors.tongdun.cn 3.8 MB/s | 3.9 kB 00:00 CentOS-8 - Extras - mirrors.tongdun.cn 1.5 MB/s | 1.5 kB 00:00 CentOS-8 - AppStream - mirrors.tongdun.cn 4.0 MB/s | 4.3 kB 00:00 Dependencies resolved. ======================================================================================================== Package Architecture Version Repository Size ======================================================================================================== Installing: epel-release noarch 8-8.el8 extras 23 k Transaction Summary ======================================================================================================== Install 1 Package Total download size: 23 k Installed size: 32 k Downloading Packages: epel-release-8-8.el8.noarch.rpm 1.6 MB/s | 23 kB 00:00 -------------------------------------------------------------------------------------------------------- Total 1.5 MB/s | 23 kB 00:00 Running transaction check Transaction check succeeded.

Installed: epel-release-8-8.el8.noarch Complete! 第三步：Linux服务器上安装RabbitMQ官方Yum存储库
要安装最新版本的RabbitMQ服务器，您可以编译首选Linux发行版的源代码
也可以添加RabbitMQ官方yum存储库以从预编译的RPM软件包中安装RabbitMQ软件。
执行以下命令以在Linux服务器上安装RabbitMQ yum存储库。
[root@rabbitmq tmp]# dnf -y install centos-release-rabbitmq-38 Last metadata expiration check: 0:03:30 ago on Mon 28 Dec 2020 10:56:30 PM CST.

现在，您可以使用dnf命令轻松安装RabbitMQ服务器。因为您已经在Linux服务器上设置了EPEL yum存储库，所以将自动解决所有依赖性。
[root@rabbitmq yum.repos.d]# ls CentOS-Base.repo CentOS-Messaging-rabbitmq.repo epel.repo [root@rabbitmq yum.repos.d]# dnf install -y rabbitmq-server Last metadata expiration check: 0:00:21 ago on Mon 28 Dec 2020 11:06:54 PM CST.

[root@rabbitmq ~]# systemctl enable --now rabbitmq-server.service Created symlink /etc/systemd/system/multi-user.target.wants/rabbitmq-server.service → /usr/lib/systemd/system/rabbitmq-server.service. 【2】查看RabbitMQ服务的状态

尽管RabbitMQ软件包已经包含CLI（命令行）工具来管理RabbitMQ服务器。
但是，您也可以选择安装RabbitMQ管理UI来执行基于GUI的管理。
【1】执行以下命令在Linux服务器上安装RabbitMQ管理UI。
[root@rabbitmq ~]# rabbitmq-plugins enable rabbitmq_management Enabling plugins on node rabbit@rabbitmq: rabbitmq_management The following plugins have been configured: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch Applying plugin configuration to rabbit@rabbitmq... The following plugins have been enabled: rabbitmq_management rabbitmq_management_agent rabbitmq_web_dispatch started 3 plugins. 
【2】验证RabbitMQ管理UI服务是否正在默认端口15672上运行。
[root@rabbitmq-01 ~]# ss -tulpn | grep 15672 tcp LISTEN 0 128 0.0.0.0:15672 0.0.0.0:* users:(("beam.smp",pid=2949,fd=98)) 
为了允许进入RabbitMQ管理UI的传入流量，您需要在Linux防火墙中允许默认服务端口15672/tcp。
此外，RabbitMQ将端口5672/tcp用于基于AMQP协议的队列。因此，您还应该在Linux防火墙中启用它。
【3】执行以下命令以允许Linux防火墙放行端口。
[root@rabbitmq ~]# firewall-cmd --add-port=15672/tcp --permanent success [root@rabbitmq ~]# firewall-cmd --add-port=5672/tcp --permanent success [root@rabbitmq ~]# firewall-cmd --reload success 第六步：RabbitMQ管理员用户与运维管理
RabbitMQ默认用户guest和密码guest。该来宾用户具有管理特权，但只能从本地主机登录到RabbitMQ服务器。
因此，我们需要创建另一个管理员用户以远程访问RabbitMQ管理UI。
【1】检查RabbitMQ服务器上已经可用的用户。
[root@rabbitmq ~]# rabbitmqctl list_users Listing users ... user tags guest [administrator] 【2】在Linux命令行上执行以下命令以创建一个用于管理RabbitMQ服务器的新用户。
# rabbitmqctl add_user [user]
[root@rabbitmq ~]# rabbitmqctl add_user admin lianglab@passwd Adding user "admin" ... # 显示用户列表 [root@rabbitmq ~]# rabbitmqctl list_users Listing users ... user tags admin [] guest [administrator] #修改用户名密码 [root@rabbitmq ~]# rabbitmqctl change_password admin lianglab@newpasswd Changing password for user "admin" ... #将管理角色授予用户如下所示 [root@rabbitmq ~]# rabbitmqctl set_user_tags admin administrator Setting tags for user "admin" to [administrator] ... #删除用户如下所示 [root@rabbitmq ~]# rabbitmqctl delete_user admin Deleting user "admin" ... 
【3】要使用RabbitMQ，也要添加Virtualhost。
＃rabbitmqctl add_vhost [vhost] #创建虚拟机主机 [root@rabbitmq ~]# rabbitmqctl add_vhost /lianglab_vhost Adding vhost "/lianglab_vhost" ... #显示虚拟主机列表 [root@rabbitmq ~]# rabbitmqctl list_vhosts Listing vhosts ... name /lianglab_vhost / #删除虚拟主机如下 [root@rabbitmq ~]# rabbitmqctl delete_vhost /lianglab_vhost Deleting vhost "/lianglab_vhost" ... [root@rabbitmq ~]# rabbitmqctl list_vhosts Listing vhosts ... name / 
【4】要向用户授予虚拟主机的权限，请进行如下配置。
# rabbitmqctl set_permissions [-p vhost] [用户] [权限⇒（修改）（写）（读）] [root@rabbitmq ~]# rabbitmqctl set_permissions -p /lianglab_vhost admin ".*" ".*" ".*" Setting permissions for user "admin" in vhost "/lianglab_vhost" ... #显示虚拟主机的权限 [root@rabbitmq ~]# rabbitmqctl list_permissions -p /lianglab_vhost Listing permissions for vhost "/lianglab_vhost" ... user configure write read admin .* .* .* #显示特定用户的权限 [root@rabbitmq ~]# rabbitmqctl list_user_permissions admin Listing permissions for user "admin" ... vhost configure write read /lianglab_vhost .* .* .* [root@rabbitmq ~]# #删除特定用户的权限如下 rabbitmqctl clear_permissions -p /lianglab_vhost admin 
【5】网络浏览器中打开URL http://192.168.6.176:15672/。
以您在先前步骤中创建的管理员用户身份登录。
成功登录后，您可以访问RabbitMQ管理UI的仪表板。您可以从此处对RabbitMQ服务器进行完全管理。
我们强烈建议您购买和阅读Manning Publications的《RabbitMQ深度》，以增加您在该领域的知识并为您的应用程序使用RabbitMQ服务器。
