Centos7 install RabbitMQ 3.6.1

If you have read the first two chapters and have a certain understanding of RabbitMQ, and now you are ready to go, come and do it!

what system

This article uses Centos7 . In order to ensure that partners who are not familiar with linux can easily get started (to avoid folding on the way of installation), the following is the address of my system mirror: https://pan.baidu.com/s/1gfl6Y9l 
As a good habit, install the system and run the update:

yum update -y

reboot  //一般情况不用重启，个人习惯。

Some people ask if I am a beginner can I use ubuntu? My answer is if you're using Centos for later production applications, it doesn't matter if you're just learning to play. Most of the production systems in my company (a Fortune 500 company, I won't name names) use Centos.

Install dependencies:

yum -y install gcc glibc-devel make ncurses-devel openssl-devel xmlto perl wget

To configure the web plugin:

Create the directory first, otherwise an error may be reported:

mkdir /etc/rabbitmq

Then enable the plugin:

rabbitmq-plugins enable rabbitmq_management

Configure the firewall:

Configure linux port 15672 web management 5672 AMQP port:

firewall-cmd --permanent --add-port=15672/tcp firewall-cmd --permanent --add-port=5672/tcp systemctl restart firewalld.service

Now you can enter the server IP: 15672 in the browser and you can see the RabbitMQ WEB management page. Are you excited, but you don't have an account and password, so don't worry. 

Configure the access account password and permissions:

The default web page is not allowed to access, you need to add a user to modify the permissions, the code is as follows:

rabbitmqctl add_user superrd superrd  //添加用户，后面两个参数分别是用户名和密码，我这都用superrd了。
rabbitmqctl set_permissions -p / superrd ".*" ".*" ".*" //添加权限 rabbitmqctl set_user_tags superrd administrator //修改用户角色

Then you can access it remotely, and then you can directly configure user permissions and other information. 
Login: http://ip:15672  After logging in, delete the guest in the admin.
