How To Deploy PMM on Linode With StackScripts
PMM (Percona Monitoring and Management) is a free and open-source platform for managing and monitoring MySQL, MongoDB, and PostgreSQL performance. It provides a comprehensive set of tools for collecting, analyzing, and visualizing metrics from your databases and servers.
Linode is a cloud computing provider that offers high-performance Linux servers with a simple and flexible pricing model. Linode also provides StackScripts, which are user-defined scripts that can be executed when deploying a new Linode instance. StackScripts can help you automate the installation and configuration of various applications and services on your Linode.
In this tutorial, we will show you how to deploy PMM on Linode with StackScripts. We will use a StackScript that installs PMM Server, which is the central component of PMM that aggregates and stores the metrics collected by PMM Client agents. We will also show you how to install PMM Client on another Linode instance and connect it to the PMM Server.
Prerequisites
A Linode account. You can sign up for one here.
Two Linode instances: one for PMM Server and one for PMM Client. You can create them using the Linode Cloud Manager or the Linode CLI. We recommend using Ubuntu 20.04 as the operating system for both instances.
A domain name or a subdomain that points to the IP address of your PMM Server instance. You can use a free service like FreeDNS or No-IP if you don't have one.
A database server running on your PMM Client instance or another server that you want to monitor with PMM. You can use any supported database server such as MySQL, MongoDB, or PostgreSQL.
Step 1: Deploying PMM Server with StackScripts
In this step, we will use a StackScript to deploy PMM Server on our first Linode instance. The StackScript we will use is called PMM Server Installer and it was created by Percona, the company behind PMM. This StackScript will install PMM Server using Docker and configure it with some basic settings.
To deploy PMM Server with StackScripts, follow these steps:
Log in to your Linode Cloud Manager and go to the Linodes page.
Select the Linode instance that you want to use as your PMM Server and click on the Rebuild tab.
Under Select an Image, choose Ubuntu 20.04 LTS.
Under Select a StackScript, click on the Community StackScripts tab and search for PMM Server Installer. Select the StackScript from the list.
Under StackScript Options, enter the following values:
PMM_SERVER_HOSTNAME: The domain name or subdomain that points to your PMM Server instance.
PMM_SERVER_ADMIN_PASSWORD: The password for the admin user of your PMM Server.
PMM_SERVER_METRICS_RETENTION: The number of days to keep the metrics data in your PMM Server. The default value is 30 days.
