RabbitMQ is an open source message queue system, a standard implementation of AMQP and is developed in the erlang language. RabbitMQ has good performance and timeliness, and can also support cluster and load deployment very well, making it very suitable for use in larger-scale distributed systems. The Rabbit mode is roughly divided into the following three types: stand-alone mode, ordinary cluster mode, and mirror mode.
The first part mainly introduces the deployment of rabbitmq stand-alone mode
Standalone mode is the simplest case, non-cluster mode, i.e. single instance service. It does not have high availability itself. If there is a problem with the node, the service will be unavailable. It is suitable for use in a simple development environment.
Deployment process:
1. Because rabbitmq is developed using erlang, you must first install erlang
yum -y install erlang
2. After the installation is completed, install rabbitmq-server
yum -y install rabbitmq-server
3. After the installation of rabbitmq-server is completed, the service will be started when the rabbitmq is started. After the startup is completed, the most basic rabbitmq stand-alone mode has been deployed, and simple services can be used.
service rabbitmq-server start
4. After the service is started, add the corresponding user and permissions.
Add vhost
sudo rabbitmqctl add_vhost /test_host
Add user and password
sudo rabbitmqctl add_user test 123456
Add user admin permissions
sudo rabbitmqctl set_user_tags test administrator
Add corresponding host permissions to the user
sudo rabbitmqctl set_permissions -p /test_host test ".*" ".*" ".*"
sudo rabbitmqctl set_permissions -p / test ".*" ".*" ".*"
5. If you need to enable management services after installation, you can access rabbitmq's web service through http://ip:15672/ after restarting.
rabbitmq-plugins enable rabbitmq_management
service rabbitmq-server restart
