System requirements

CentOS 6.8

CentOS 7

Install EMQ X

You can install EMQ X in different ways as needed:

Set up and install the mirror library for EMQ X to facilitate installation and upgrade tasks.

Download the package manually and install it.

Install EMQ X using the Mirror Library

Before you install EMQ X for the first time on a new host, you need to set up the EMQ X Mirror Library. You can then install and update EMQ X from the Mirror Library.

Set up the mirror library

1. Install the required packages.

$sudo yum install-y yum-utils device-mapper-persistent-data lvm2

two。 Use the following command to set up a stable mirror library, taking centos7 as an example.

$sudo yum-config-manager-- add-repo https://repos.emqx.io/emqx-ce/redhat/centos/7/emqx-ce.repo installs EMQ X

1. Install the latest version of EMQ X, or go to the next step to install a specific version:

$sudo yum install emqx

If prompted to accept the GPG key, verify that the fingerprint matches the fc84 1ba6 3775 5ca8 487b 1e3c c0b4 0946 3e64 0d53, and if so, accept the fingerprint.

If multiple EMQ X mirror libraries are enabled, the highest possible version will always be installed if no version is specified in the yum install or yum update command, which may not be suitable for stability requirements.

two。 To install a specific version of EMQ X, you need to list the available versions, then select and install:

Query available version

$yum list emqx--showduplicates | sort-remqx.x86_64 3.1.0-1.el7 emqx-stableemqx.x86_64 3.0.1-1.el7 emqx-stableemqx.x86_64 3.0.0-1.el7 emqx-stable

The list returned depends on the enabled mirror library and is specific to the CentOS version (represented by the .el7 suffix in this example).

Install a specific version using the version string in the second column, such as 3.1.0

$sudo yum install emqx-3.1.0

3. Start EMQ X

$emqx startemqx 3.1 is started fully fulfilled $emqx_ctl statusNode 'emqx@127.0.0.1' is startedemqx v3.1.0 is running

4.EMQ X started successfully. Please refer to the official documentation on how to use it.

Install EMQ X using the package

If you cannot install EMQ X using EMQ X's mirror library, you can download a .rpm file or a .zip file and install it manually.

two。 Install EMQ X and change the path below to the path where you downloaded the EMQ X package.
