RabbitMQ offline installation under Linux: 4 easy steps, system performance soars

RabbitMQ, as a powerful and stable information storage and processing framework, is increasingly used in distributed environments. However, problems such as network failures during actual application make offline deployment and maintenance of RabbitMQ particularly important. Here, we will explain to you how to efficiently complete the offline installation of RabbitMQ on the Linux operating system, thereby improving system performance and reliability.

1. Prepare the installation package

The first step to download the latest version of RabbitMQ compressed package and store it in a predetermined path is to obtain the RabbitMQ installer. Just follow the instructions on the official website.

2. Install dependencies

Follow the above guidelines for red flag linux, you need to first ensure that the supporting resource libraries required by RabbitMQ have been correctly deployed and configured. For this reason, we recommend that the following steps be rigorously executed in the virtual terminal:

sudo apt-get update

Using the NoX version of the Erlang software package, you can successfully install the relevant components by simply entering the command "sudo apt-get install erlang-nox".

3. Configure environment variables

In order to accurately use the RabbitMQ command line tool, you need to set the corresponding environment variables. Please enter the following instructions in the execution environment:

Be sure to set the value of the $PATH environment variable to:/path/to/rabbitmq/sbin.

4. Start RabbitMQ

Now, start RabbitMQ! Enter the following command in this terminal.

rabbitmq-server -detached

This will start the RabbitMQ server in background mode.

5. Create an administrator account

To achieve full control of RabbitMQ, the first task is to set up an administrator account with operating rights.

rabbitmqctl add_user

Using RabbitMQ's CLI tool "rabbitmqctl", administrators can easily configure user identifiers.

Use the RabbitMQ system configuration software rabbitmqctl settingsLinux offline installation of rabbitmq to ensure that all users have reading and editing privileges for the entire region queue.

6. Configure firewall rules

To ensure the stable operation of the system, firewall rules need to be set to only allow restricted static IPs to access RabbitMQ. Specific operations can be completed using Linux commands.

Use super permissions to enable 5672 traffic from any port on uFW

In the firewall settings, add rules for specific IP addresses to allow them to access specific network services (port number 15672) without review.

sudo ufw reload

7. Configure the cluster

In order to meet the requirements for cluster environment construction, according to relevant laws and regulationsLinux offline installation of rabbitmqHongqi linux official website, we need to make the following specific settings for multiple RabbitMQ servers.

-Make sure that each node follows steps 1 to 4 and belongs to the same network.

-Execute the following command on one of the nodes:

rabbitmqctl stop_app

rabbitmqctl reset

Use the rabbitmqctl command to successfully access the cluster named 'rabbit' and set it to operate in memory swap file mode.

rabbitmqctl start_app

-Execute the following commands on other nodes:

This operation requires the use of the RabbitMQctl command to set the specified title to "rabbit@", and then proceed with the cluster integration operation process.

8. Using RabbitMQ

Using the RabbitMQ architecture, an efficient and reliable message queue system is easily available. Whether configuring from the console or viewing it in the monitoring and management window, basic functions such as queue construction, message publishing and consumption can be easily implemented.

9. Solving common problems

When using rabbitMQ, please pay attention to the following core points and take corresponding countermeasures:

When a RabbitMQ startup failure occurs, you must first confirm whether the 5672 encrypted channel is not occupied by a third-party application.

-If you forget the password of the administrator account, you can execute the following command to reset the password:

rabbitmqctl change_password

10. Summary

Follow the offline operation guidance provided in this article, and you will be able to fully master the skills to successfully install and configure RabbitMQ applications in a Linux environment. We expect you to demonstrate excellent technical wisdom throughout the entire process and ensure the stable and efficient operation of the message channel system.
