第一步：安装yum仓库
导入签名KEY：
代码语言：javascript复制## 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
## modern Erlang repository
rpm --import https://packagecloud.io/rabbitmq/erlang/gpgkey
## RabbitMQ server repository
rpm --import https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey手动配置Yum源： 新建文件“/etc/yum.repos.d/rabbitmq.repo”，编辑如下内容：
代码语言：javascript复制# In /etc/yum.repos.d/rabbitmq.repo
##
## Zero dependency Erlang
##
[rabbitmq_erlang]

gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300第二步：执行安装
更新Yum包元数据：
代码语言：javascript复制yum update -y特别地，在腾讯云主机CentOS 8.2操作系统上安装时遇到无法从AppStream下载问题，解决办法参考：完美解决CentOS8 yum安装AppStream报错，更新yum后无法makecache的问题
另外还要注意：腾讯云主机的CentOS 8.2操作系统基础yum仓库文件的名字都是“CentOS-Linux-.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。
安装依赖：
代码语言：javascript复制## install these dependencies from standard OS repositories
yum install socat logrotate -y安装Erlang和RabbitMQ：
代码语言：javascript复制## 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第三步：启动服务
设置开机启动：
代码语言：javascript复制chkconfig rabbitmq-server on安装服务工具：
代码语言：javascript复制yum -y install initscripts启动服务：
代码语言：javascript复制# 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：
代码语言：javascript复制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
tcp6 0 0 :::5672 :::* LISTEN 84521/beam.smp默认服务端口5672已经处于监听状态，表明RabbitMQ服务启动成功。
第四步：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。
手动启用Web管理插件：rabbitmq-plugins enable rabbitmq_management 。
再次查看监听端口：
netstat -anpt
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 84521/beam.smp
tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 84521/beam.smp
tcp6 0 0 :::5672 :::* LISTEN 84521/beam.smp查看插件列表状态；
代码语言：javascript复制rabbitmq-plugins list
Listing plugins with pattern ".*" ...
Configured: E = explicitly enabled; e = implicitly enabled

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。
代码语言：javascript复制# grep 'config file' /var/log/rabbitmq/rabbit@VM-24-10-centos.log
2022-03-17 16:51:36.534481 08:00 [info] <0.230.0> config file(s) : (none) # 从这里可以看出RabbitMQ在启动时没有明确指定配置文件解决办法：
（1）通过环境变量RABBITMQ_CONFIG_FILE指定RabbitMQ配置文件路径
# vim .bashrc
export RABBITMQ_CONFIG_FILE=/etc/rabbitmq/rabbitmq.conf文件/etc/rabbitmq/rabbitmq.conf可能不存在，创建一个即可。
RabbitMQ的配置文件参数示例：rabbitmq.conf.example，可以直接下载下来使用，里面都是默认配置参数。
（2）修改允许远程访问Web界面的参数：将loopback_users.guest参数修改为false
loopback_users.guest = false（3）重启RabbitMQ服务
代码语言：javascript复制/sbin/service rabbitmq-server stop
/sbin/service rabbitmq-server start现在再来看RabbitMQ是否在启动时使用了指定配置文件：
代码语言：javascript复制grep 'config file' /var/log/rabbitmq/rabbit@VM-24-10-centos.log
2022-03-17 16:51:36.534481 08:00 [info] <0.230.0> config file(s) : (none)
2022-03-17 17:22:09.174170 08:00 [info] <0.230.0> config file(s) : /etc/rabbitmq/rabbitmq.conf # 显然，从启动日志看RabbitMQ现在使用了指定的配置文件【参考】 https://github.com/rabbitmq/rabbitmq-server/blob/master/deps/rabbit/docs/rabbitmq.conf.example RabbitMQ官方配置文件示例 https://www.rabbitmq.com/relocate.html RabbitMQ环境变量含义 https://blog.csdn.net/qq_27198345/article/details/115384898 RabbitMQ的默认配置文件地址 https://blog.csdn.net/PacosonSWJTU/article/details/114198834 rabbitmq启动失败-报Failed to load advanced configuration file解决方法
