Install Memory Machine
To install Memory Machine 1.5.0, we need to verify that any previous memory viewer installations are removed, download the Memory Machine software, then install that software.
1. Remove a Previous Memory Machine Installation
Uninstalling Memory Machine 1.3.0 and older
To confirm if the mvmv package is currently installed, use:
RHEL/CentOS/Fedora:
Ubuntu
To remove the currently installed package and dependencies, use:

2. Install Memory Machine Prerequisites
Memory Machine 1.5.0 requires the following software to be installed for the root user:
- Python 3.10.x
- PIP
- PyEnv
Install Python 3.10
Check the Existing Python Version. Ubuntu 22.04 has Python 3.10 available. You can verify this by running:
Ubuntu 22.04: If Python 3.10 is not installed, you can install it using:
Install PIP and PyEnv
Run the following to install these packages:
3. Download Memory Machine
Download the Memory Machine package from the MemVerge download site:
If the host has an Internet connection, use curl or wget to download the file directly on the target server.
For example:
wget https://memory-viewer-bucket.s3.amazonaws.com/releases/v1.5.0/Cell_Mgmt_1.5.0-20241011191325.bin
If the host does not have Internet access, download it and the dependency packages to a host that does, then transfer the packages to the target server.
4. Install Memory Machine
Ensure the downloaded BIN file is executable:
The usage information shows options to specify non-default values:
$ sudo ./Cell_Mgmt_1.5.0-20241011191325.bin --help

./Cell_Mgmt_1.5.0-20240531010915.bin
Options:
--install-path Optional. Default is /opt/memverge. Specify CXL Memory Machine install path
--install=[SERVICE] Optional.
SERVICE='all', default, install both mmmgr and mmlet services
SERVICE='management-host', install only mmmgr service on management-host
SERVICE='compute-host', install only mmlet service on compute-host
--mmmgr-port=[PORT] Optional. Default port is 8081
--mmlet-port=[PORT] Optional. Default port is 8090
--prometheus-port=[PORT] Optional. Default port is 8091
--grafana-port=[PORT] Optional. Default port is 8092
--caddy-port=[PORT] Optional. Default port is 8080
--help Print this help message
Install the Management and Host Agent on the same system
If this is the first time installing Memory Machine, or you intend to use Memory Machine on a single system, it is recommended to install both the Management and Host agent together. This is the default installation method when no options or arguments are provided to the installer. Run the following:
Installation Example:
$ sudo ./Cell_Mgmt_1.5.0-20241011191325.bin

Adding Compute Host to Management Host list ...
Install completed.
Successfully installed MemVerge CXL Memory Machine to "/opt/memverge", see "/var/log/memverge/package_install.log" for details.
Install the Management Host Service
To install only the Management service, run:
Install the Client Host Agent
To install only the Client services and register the host with a running Management Server on a different system, run:
During the installation, you will see the following prompted question so the client can register itself with the management host. The management host must be reachable, and the services must be running; otherwise, this process will fail.
Please provide management server address the compute host will register with (optional). Press ENTER if none:
If you skip this question, you can manually register a client with the management server by running /opt/memverge/bin/mmcli hosts add ip:port on the management server. The client agent software must be installed and running on the client.

Register a Client with the Management Server
If you skipped the client registration step when the client software was installed, you can register a client with the management server by running /opt/memverge/bin/mmcli hosts add ip:port on the management server. The client agent software must be installed and running on the client.
