Message queue RabbitMQ installation configuration details

RabbitMQ is a mainstream enterprise message team product. Its implementation based on the Erlang language enables it to have efficient message processing capabilities; based on RabbitMQ's high efficiency and reliability guarantee for messages, it has been widely used in enterprises. Next, Brother Tao will tell you about the detailed installation and configuration tutorial of RabbitMQ~

1. Introduction to RabbitMQ

RabbitMQ is a reusable enterprise messaging system based on AMQP. He follows the Mozilla Public License open source agreement.

AMQP, or Advanced Message Queuing Protocol, is an application layer standard advanced message queuing protocol that provides unified messaging services. It is an open standard for application layer protocols and is designed for message-oriented middleware. The client and message middleware based on this protocol can transmit messages, and it is not limited by different client/middleware products, different development languages and other conditions. Implementations in Erlang include RabbitMQ, etc.

The main features are as follows:

Guaranteed reliability: Use some mechanisms to ensure reliability, such as persistence, transmission confirmation, release confirmation
Flexible Routing Function
Scalability: support message cluster, multiple RabbitMQ servers can form a cluster
High availability: the queue is still available when a node in the RabbitMQ cluster fails
Support multiple protocols
Support multilingual clients
Provides a nice admin interface
Provide tracking mechanism: If the message is abnormal, the cause of the exception can be analyzed through the tracking mechanism
Provide plug-in mechanism: it can be extended in many ways through plug-ins

2. Environment preparation before installation

Linux：CentOS 7.6
RabbitMQ：RabbitMQ 3.7

If you have installed erlang before, please delete it first!

yum remove erlang*

Install the C++ compilation environment

# yum -y install make gcc gcc-c++
yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC unixODBC-devel httpd python-simplejson

Download erlang and rabbitMQ

wget http://www.erlang.org/download/otp_src_20.1.tar.gz

Download RabbitMQ

wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.7.0/rabbitmq-server-generic-unix-3.7.0.tar.xz

3. Install the erlang environment

Create the /usr/local/erlang directory where we will install erlang.

Unzip the erlang installation package

tar -xvf otp_src_20.1.tar.gz

Go to the unzipped folder

cd otp_src_20.1

Erlang needs to rely on JDK, so you need to complete the installation of JDK and configuration of environment variables first. Specify the installation directory and installation configuration

./configure --prefix=/usr/local/erlang --enable-smp-support --enable-threads --enable-sctp --enable-kernel-poll --enable-hipe --with-ssl --without-javac

Compile and install

make && make install

Configure the erlang environment variable: add export PATH=$PATH:/usr/local/erlang/bin to the end of the file

vi /etc/profile

reload profile file

source /etc/profile

4. Install RabbitMQ

4.1 Decompress RabbitMQ

Since the downloaded installation package is an xz file, we first decompress xz into tar.

xz -d rabbitmq-server-generic-unix-3.7.0.tar.xz

tar -xvf rabbitmq-server-generic-unix-3.7.0.tar

4.2 Start RabbitMQ

Go to the sbin directory of the decompressed RabbitMQ

cd rabbitmq_server-3.7.0/sbin

Start RabbitMQ

./rabbitmq-server -detached

View the process, the default port of RabbitMQ is 5672

lsof -i:5672

# 或者
ps aux|grep rabbit
#ps a 显示现行终端机下的所有程序，包括其他用户的程序。
#ps u 　 以用户为主的格式来显示程序状况。
#ps x 　 显示所有程序，不以终端机来区分。

5. Start the RabbitMQ management system

Start the RabbitMQ management system plug-in (need to enter the sbin directory)

./rabbitmq-plugins enable rabbitmq_management

Access management system: http://119.23.237.251:15672/

6. Cloud Host Security Group Settings

If the RabbitMQ server is based on a cloud host, normal access to the management system requires security group settings.

6.1 Alibaba Cloud Server

6.2 Huawei Cloud Server

7. Summary

The process of installation and configuration focuses on the details, don't make mistakes in the instructions and directories! The above is the detailed process of installing RabbitMQ based on Linux, have you learned it?
