CentOS 安装 RabbitMQ(超级简单)

1.安装yum仓库签名

1.1.导入签名lay：

## primary RabbitMQ signing key
## 这一步如果因为网络问题下载不成功，可以先将签名文件下载下来，本地导入
rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc

2.手动添加yum源

使用sudo管理员命令新建文件vi /etc/yum.repos.d/rabbitmq.repo，编辑如下内容：

# 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
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
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
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
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
# PackageCloud's repository key and RabbitMQ package signing key
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
       https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
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

3.执行安装

更新yum源数据：

yum update -y

特别地，在CentOS 操作系统上安装时遇到无法从AppStream下载问题，可以把/etc/yum.repos.d/里面的文件全部删除 rm -rf xxx然后在重新更新系统源 阿里源 在重新第二步开始
另外还要注意：CentOS 操作系统基础yum仓库文件的名字都是“CentOS-xxxx-.repo”，而不是标准的“CentOS-.repo”命名方式，所以修改的时候不要搞错文件。

3.1安装RabbitMQ依赖

## Basic dependence
## 基本依赖
yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto perl wget
## install these dependencies from standard OS repositories
yum install socat logrotate -y

3.2安装Erlang和RabbitMQ

## install RabbitMQ and zero dependency Erlang from the above repositories,
## ignoring any versions provided by the standard repositories
yum install --repo rabbitmq_erlang --repo rabbitmq_server erlang rabbitmq-server -y

4.启用Web管理

RabbitMQ的Web管理界面是通过插件实现的，默认并不启用，所以在查看端口的时候也不会看到管理端口15672在监听。

4.1.手动启用Web管理插件

## web
rabbitmq-plugins enable rabbitmq_management

4.2.查看插件列表状态

[root@VM-4-3-centos ~]# rabbitmq-plugins list
Listing plugins with pattern ".*" ...
 Configured: E = explicitly enabled; e = implicitly enabled
 | Status: * = running on rabbit@VM-4-3-centos

[  ] rabbitmq_web_stomp                3.10.7
[  ] rabbitmq_web_stomp_examples       3.10.7

可以看到跟Web管理相关的插件都启用了。

至此，虽然RabbitMQ的Web管理插件已经启用，但是只能在通过本机地址打开Web界面，如果希望从远程访问Web界面（大多数场景就是这样的），还需要进行配置。

默认情况下，启动RabbitMQ Server是没有明确指定配置文件的，也就是我们无法修改允许远程访问Web管理界面的参数。我们可以添加一个用户

5.添加用户

## username :admin | password:admin
rabbitmqctl add_user admin admin
## Assign role rights to a user Super administrator
## 赋予用户角色权限 超级管理员(administrator)
rabbitmqctl set_user_tags admin administrator
## Open write and read permissions for all resources
## 开放所有资源的写权限和读权限
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

最后启动服务

设置开机启动：

chkconfig rabbitmq-server on

启动服务：

# 启动服务
/sbin/service rabbitmq-server start

# 查看服务状态
/sbin/service rabbitmq-server status

# 停止服务
/sbin/service rabbitmq-server stop

查看服务端口是否已经正常：

netstat -anpt

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:25672           0.0.0.0:*               LISTEN      84521/beam.smp

进行登录

成功
