安装rabbitMQ

环境：CentOS 8
来源：https://www.rabbitmq.com/install-rpm.html

Install Using PackageCloud Yum Repository

## 在PackageCloud中可以找到一个包含RabbitMQ包的Yum库。Package Cloud也可以通过yum安装一个最新的Erlang版本。
curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash
## Uses a PackageCloud-provided Yum repository setup script.
## Always verify what is downloaded before piping it to a privileged shell!
curl -s https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.rpm.sh | sudo bash

## Yum将验证它安装的任何包的签名，因此该过程的第一步是导入签名密钥
## primary RabbitMQ signing key
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

创建文件/etc/yum.repos.d/rabbitmq.repo

##
## Zero dependency Erlang

Install Packages with Yum

## 更新Yum包元数据:
yum update -y
yum -q makecache -y --disablerepo='*' --enablerepo='rabbitmq_erlang' --enablerepo='rabbitmq_server'

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

## 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

方法二：通过rpm包安装

wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.9.13/rabbitmq-server-3.9.13-1.el8.noarch.rpm

rpm --import https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc
## install these dependencies from standard OS repositories
yum install socat logrotate -y
# This example assumes the CentOS 8 version of the package, suitable for
# Red Hat 8, CentOS Stream 9, CentOS 8 and modern Fedora releases.
#
# For Red Hat 7 or CentOS 7, replace "el8" with "el7".
yum install rabbitmq-server-3.9.13-1.el8.noarch.rpm

运行和检测

sudo service rabbitmq-server start

sudo service rabbitmq-server status

sudo service rabbitmq-server stop

# checks if the local node is running and CLI tools can successfully authenticate with it
sudo rabbitmq-diagnostics ping

# prints enabled components (applications), TCP listeners, memory usage breakdown, alarms
# and so on
sudo rabbitmq-diagnostics status

# prints cluster membership information
sudo rabbitmq-diagnostics cluster_status

# prints effective node configuration
sudo rabbitmq-diagnostics environment

日志文件和管理

服务器日志可以在可配置的目录下找到，当通过Linux包管理器安装RabbitMQ时，该目录通常默认为/var/log/rabbitmq。
RABBITMQ_LOG_BASE 可以用来覆盖日志目录位置
基于systemd-based的发行版系统，需要有sudo权限，可以使用：
sudo journalctl --system | grep rabbitmq
默认日志会每周打包压缩到地址：/var/log/rabbitmq，可以再这里配置：/etc/logrotate.d/rabbitmq-server
