Installing on RPM-based Linux (RHEL, CentOS Stream, Fedora, Amazon Linux 2023, openSUSE)

Overview

This guide covers RabbitMQ installation on RPM-based Linux (Red Hat Enterprise Linux, CentOS Stream, Fedora, openSUSE).

With the exception of Fedora, the versions included into standard RPM-based distribution repositories can be many releases behind latest RabbitMQ releases and may provide RabbitMQ versions that are already out of support.

Team RabbitMQ produces our own RPM packages and distributes them using a Cloudsmith mirror.

There are two ways of installing these RPMs:

• Installing the package using Yum repositories (this option is highly recommended) from a Cloudsmith.io mirror
• Downloading the package and installing it with rpm. This option will require manual installation of all package dependencies and makes upgrades more difficult.

Some of the topics covered in this guide are:

• Supported distributions
• Package installation from Yum repositories on a Cloudsmith.io mirror
• How to install a latest supported Erlang/OTP version
• Package dependencies
• Privilege requirements
• How to manage the service (start it, stop it, and get its status)
• How to inspect node and service logs
• Direct download links for the RabbitMQ RPM package

and more.

Supported Distributions

RabbitMQ is supported on several major RPM-based distributions that are still actively maintained by their primary vendor or developer group.

Note that modern versions of Erlang can have incompatibilities with older distributions (e.g. older than three to four years) or ship without much or any testing on older distributions or OS kernel versions.

Older distributions can also lack a recent enough version of OpenSSL. Erlang 24 cannot be used on distributions that do not provide OpenSSL 1.1 as a system library. CentOS 7 and Fedora releases older than 26 are examples of such distributions.

Currently the list of supported RPM-based distributions includes

• Fedora 34 through 38
• CentOS Stream 9.x and 8.x
• RedHat Enterprise Linux 9.x and 8.x
• Amazon Linux 2023
• Rocky Linux 9.x and 8.x
• Alma Linux 9.x and 8.x
• Oracle Linux 9.x and 8.x
• openSUSE Leap 15.3 and later versions

The packages may work on other RPM-based distributions if dependencies are satisfied but their testing and support is done on a best effort basis.

User Privilege Requirements

RabbitMQ RPM package will require sudo privileges to install and manage. In environments where sudo isn't available, consider using the generic binary build.

Install Erlang

Before installing RabbitMQ, you must install a supported version of Erlang/OTP. Standard Red Hat, Fedora, CentOS repositories provide Erlang versions that are typically out of date and cannot be used to run latest RabbitMQ releases.

There are three alternative sources for modern Erlang on RPM-based distributions:

• Team RabbitMQ produces a package stripped down to only provide those components needed to run RabbitMQ. This is the recommended option.
• openSUSE produces Erlang packages for openSUSE Leap
• Erlang Solutions produces packages that are usually reasonably up to date and involve installation of a potentially excessive list of dependencies

Zero-dependency Erlang from RabbitMQ

Zero dependency Erlang RPM package for running RabbitMQ can be installed from a direct download from GitHub, as well as Yum repository, as described in its README.

As the name suggests, the package strips off some Erlang modules and dependencies that are not essential for running RabbitMQ.

Erlang packages from openSUSE

openSUSE package repositories provide Erlang so it can be installed using Zypper:

sudo zypper in erlang

Erlang versions available in the standard repositories will in practice be behind the most recent version. To use the last version with the newest features, add the openSUSE Factory repositories for Erlang:

# add the openSUSE erlang factory, obs:// extracts the http url for the matching distro.
sudo zypper ar -f  obs://devel:languages:erlang:Factory openSUSE-Erlang-Factory

# import the signing key and refresh the repository
sudo zypper --gpg-auto-import-keys refresh

# install a recent Erlang version
sudo zypper in erlang

Package Dependencies

When installing with Yum, all dependencies other than Erlang/OTP should be resolved and installed automatically as long as compatible versions are available. When that's not the case, dependency packages must be installed manually.

However, when installing a local RPM file via yum dependencies must be installed manually. The dependencies are:

• erlang: a supported version of Erlang can be installed from a number of repositories
• socat
• logrotate

Install Using a Cloudsmith Mirror Yum Repository

A Yum repository with RabbitMQ packages is available from Cloudsmith and a mirror of the repositories there.

The rest of this section will demonstrate how to set up a repository file that will use a mirror. Repositories on Cloudsmith are subject to traffic quotas but the mirror is not.

Install RabbitMQ and Cloudsmith Signing Keys

Yum will verify signatures of any packages it installs, therefore the first step in the process is to import the signing key

## primary RabbitMQ signing key
rpm --import 'https://github.com/rabbitmq/signing-keys/releases/download/3.0/rabbitmq-release-signing-key.asc'
## modern Erlang repository
rpm --import 'https://github.com/rabbitmq/signing-keys/releases/download/3.0/cloudsmith.rabbitmq-erlang.E495BB49CC4BBE5B.key'
## RabbitMQ server repository
rpm --import 'https://github.com/rabbitmq/signing-keys/releases/download/3.0/cloudsmith.rabbitmq-server.9F4587F226208342.key'

Add Yum Repositories for RabbitMQ and Modern Erlang

In order to use the Yum repository, a .repo file (e.g. rabbitmq.repo) has to be added under the /etc/yum.repos.d/ directory. The contents of the file will vary slightly between distributions (e.g. CentOS Stream 9, CentOS Stream 8, or OpenSUSE).

Red Hat 8, CentOS Stream 8, Modern Fedora Releases

The following example sets up a repository that will install RabbitMQ and its Erlang dependency from a Cloudsmith mirror, and targets CentOS Stream 8. The same repository definition can be used by recent Fedora releases, and Amazon Linux 2023.

Install Packages with dnf (yum)

Update package metadata:

dnf update -y

Next install dependencies from the standard repositories:

## install these dependencies from standard OS repositories
dnf install socat logrotate -y

Finally, install modern Erlang and RabbitMQ:

## install RabbitMQ and zero dependency Erlang
dnf install -y erlang rabbitmq-server

Install Packages with Zypper

First, update Zypper package metadata:

## refresh the RabbitMQ repositories
zypper --gpg-auto-import-keys refresh rabbitmq_server
zypper --gpg-auto-import-keys refresh rabbitmq_server-noarch
zypper --gpg-auto-import-keys refresh rabbitmq_server-source

Then install the packages:

## install the package from Cloudsmith repository
zypper install --repo rabbitmq_server-noarch

Package Version Locking in On RPM-based Distributions

yum version locking plugin can be used to prevent unexpected package upgrades. Using it carries the risk of leaving the system behind in terms of updates, including important bug fixes and security patches.

With rpm and a Direct Download

After downloading the server package, issue the following command as 'root':

rpm --import https://github.com/rabbitmq/signing-keys/releases/download/3.0/rabbitmq-release-signing-key.asc

## install these dependencies from standard OS repositories
dnf install socat logrotate -y

# This example assumes the CentOS Stream 8 version of the package, suitable for
# Red Hat 8, CentOS Stream 9, CentOS Stream 8 and modern Fedora releases.
dnf install rabbitmq-server-3.12.5-1.el8.noarch.rpm

RabbitMQ public signing key can also be downloaded from rabbitmq.com:

rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

## install these dependencies from standard OS repositories
dnf install socat logrotate -y

# This example assumes the CentOS 8 version of the package, suitable for
# Red Hat 8, CentOS Stream 9, CentOS Stream 8 and modern Fedora releases.
dnf install rabbitmq-server-3.12.5-1.el8.noarch.rpm

Direct Downloads

In some cases it may be easier to download the package and install it manually. The package can be downloaded from GitHub.

Run RabbitMQ Server

Start the Server

The server is not started as a daemon by default when the RabbitMQ server package is installed. To start the daemon by default when the system boots, as an administrator run

systemctl enable rabbitmq-server

As an administrator, start and stop the server as usual, e.g. using systemctl:

systemctl start rabbitmq-server

systemctl status  rabbitmq-server

systemctl stop rabbitmq-server

Configuring RabbitMQ

On most systems, a node should be able to start and run with all defaults. Please refer to the Configuration guide to learn more and Production Checklist for guidelines beyond development environments.

Note: the node is set up to run as system user rabbitmq. If location of the node database or the logs is changed, the files and directories must be owned by this user.

RabbitMQ nodes bind to ports (open server TCP sockets) in order to accept client and CLI tool connections. Other processes and tools such as SELinux may prevent RabbitMQ from binding to a port. When that happens, the node will fail to start. Refer to the Networking Guide for more details.

Default User Access

The broker creates a user guest with password guest. Unconfigured clients will in general use these credentials. By default, these credentials can only be used when connecting to the broker as localhost so you will need to take action before connecting from any other machine.

See the documentation on access control for information on how to create more users and delete the guest user.

Controlling System Limits on Linux

RabbitMQ installations running production workloads may need system limits and kernel parameters tuning in order to handle a decent number of concurrent connections and queues. The main setting that needs adjustment is the max number of open files, also known as ulimit -n. The default value on many operating systems is too low for a messaging broker (1024 on several Linux distributions). We recommend allowing for at least 65536 file descriptors for user rabbitmq in production environments. 4096 should be sufficient for many development workloads.

There are two limits in play: the maximum number of open files the OS kernel allows (fs.file-max) and the per-user limit (ulimit -n). The former must be higher than the latter.

With systemd (Recent Linux Distributions)

On distributions that use systemd, the OS limits are controlled via a configuration file at /etc/systemd/system/rabbitmq-server.service.d/limits.conf. For example, to set the max open file handle limit (nofile) to 64000:

[Service]
LimitNOFILE=64000

See systemd documentation to learn about the supported limits and other directives.

With Docker

To configure kernel limits for Docker contains, use the "default-ulimits" key in Docker daemon configuration file. The file has to be installed on Docker hosts at /etc/docker/daemon.json:

{
  "default-ulimits": {
    "nofile": {
      "Name": "nofile",
      "Hard": 64000,
      "Soft": 64000
    }
  }
}

Without systemd (Older Linux Distributions)

The most straightforward way to adjust the per-user limit for RabbitMQ on distributions that do not use systemd is to edit the /etc/default/rabbitmq-server (provided by the RabbitMQ Debian package) or rabbitmq-env.conf to invoke ulimit before the service is started.

ulimit -S -n 64000

This soft limit cannot go higher than the hard limit (which defaults to 4096 in many distributions). The hard limit can be increased via /etc/security/limits.conf. This also requires enabling the pam_limits.so module and re-login or reboot. Note that limits cannot be changed for running OS processes.

For more information about controlling fs.file-max with sysctl, please refer to the excellent Riak guide on open file limit tuning.

Verifying the Limit

RabbitMQ management UI displays the number of file descriptors available for it to use on the Overview tab.

rabbitmq-diagnostics status

includes the same value.

The following command

cat /proc/$RABBITMQ_BEAM_PROCESS_PID/limits

can be used to display effective limits of a running process. $RABBITMQ_BEAM_PROCESS_PID is the OS PID of the Erlang VM running RabbitMQ, as returned by rabbitmq-diagnostics status.

Configuration Management Tools

Configuration management tools (e.g. Chef, Puppet, BOSH) provide assistance with system limit tuning. Our developer tools guide lists relevant modules and projects.

Managing the Service

To start and stop the server, use the service tool. The service name is rabbitmq-server:

# stop the local node
sudo service rabbitmq-server stop

# start it back
sudo service rabbitmq-server start

service rabbitmq-server status will report service status as observed by systemd (or similar service manager):

# check on service status as observed by service manager
sudo service rabbitmq-server status

It will produce output similar to this:

# checks if the local node is running and CLI tools can successfully authenticate with it
sudo rabbitmq-diagnostics ping

# prints enabled components (applications), TCP listeners, memory usage breakdown, alarms
# and so on
sudo rabbitmq-diagnostics status

# prints cluster membership information
sudo rabbitmq-diagnostics cluster_status

# prints effective node configuration
sudo rabbitmq-diagnostics environment

All rabbitmqctl commands will report an error if no node is running. See the CLI tools and Monitoring guides to learn more.

Log Files and Management

Server logs can be found under the configurable directory, which usually defaults to /var/log/rabbitmq when RabbitMQ is installed via a Linux package manager.

RABBITMQ_LOG_BASE can be used to override log directory location.

Assuming a systemd-based distribution, system service logs can be inspected using

journalctl --system

which requires superuser privileges. Its output can be filtered to narrow it down to RabbitMQ-specific entries:

sudo journalctl --system | grep rabbitmq

The output will look similar to this:

Log Rotation

The broker always appends to the log files, so a complete log history is retained.

logrotate is the recommended way of log file rotation and compression. By default, the package will set up logrotate to run weekly on files located in default /var/log/rabbitmq directory. Rotation configuration can be found in /etc/logrotate.d/rabbitmq-server.
