Installation of RabbitMQ under CentOS8

RabbitMQ installation

I used to install erlang and rabbitmq through rpm. Every time there was a problem. The version of erlang was wrong or the rabbitmq installation lacked a so library, etc. It crashed. Later, I went to the official website of rabbitmq and installed it successfully according to the tutorial. Check the official website tutorial below for how to operate:

The environment describes the centos8 version of your own virtual machine:

1. Find the corresponding version and add the configuration file (find your own linux version)

Enter the specified location through the command:

 cd /etc/yum.repos.d                 到指定的目录
 ll -a                               查看是否有rabbitmqrepo配置
 vi /etc/yum.repos.d/rabbitmq.repo   没有添加rabbitmq.repo 配置

Configure the following content directly in the rabbitmq.repo file:

# In /etc/yum.repos.d/rabbitmq.repo

## Zero dependency Erlang

2. Install by command

Update Yum package metadata:

yum update -y
yum -q makecache -y --disablerepo='*' --enablerepo='rabbitmq_erlang' --enablerepo='rabbitmq_server'

Next install dependencies from the standard repositories:

yum install socat logrotate -y

Finally, install modern Erlang and RabbitMQ:

yum install --repo rabbitmq_erlang --repo rabbitmq_server erlang rabbitmq-server -y

Explanation: This command has been operated several times, saying that the network problem failed to download successfully, and it needs to be executed several times

Successful installation:
