Working with Redis in Memory Machine
Starting a Redis Server

Overview and Installation
Getting started with MemVerge Memory Machine requries that you understand some background information about how persistent memory works. You can then install Memory Machine on a server and begin monitoring memory usage and capturing application snapshots.
Using the Memory Machine Dashboard
You can view system resources and performance metrics, and create and restore snapshots in MemVerge Memory Machine using the Memory Machine Dashboard, a web UI application running on one of the installed hosts.
Using the Command Line Interface
You can administer and use MemVerge Memory Machine using the Command Line Interface (CLI) on any installed host.

Starting a Redis Server

Before you begin

Install Redis on the Memory Machine server. This example assumes that Redis 5.0.7 is installed.

Use ssh to log onto the server using a privileged account (this example uses the root account).

About this task

This example describes how to start a Redis server in Memory Machine using the command line interface (CLI).

Procedure

Use the supplied command mm to start the Redis server:

$ mm redis-server --port 9998 --daemonize yes

where:

--port: Specifies the port on which the Redis server listens.
--daemonize yes: Starts the process as a daemon and detaches it from the terminal window.

You cannot capture a snapshot of a process with an attached tty terminal using the Memory Machine Dashboard. For this reason, detach the Redis server process from the terminal by using the --daemonize yes option instead of appending an ampersand.
