Subject: Migrating Virtualmin Master Server from CentOS 7.9 to AlmaLinux 9.1

Good day from Singapore,

Author: Mr. Turritopsis Dohrnii Teo En Ming (TARGETED INDIVIDUAL) Country: Singapore Date: 15 Dec 2022 Thursday

I have successfully migrated Virtualmin Master Server from CentOS 7.9 to AlmaLinux 9.1 on 14 Dec 2022 Wed from 4.00 PM to 7.30 PM Singapore Time.

Even though I have a fever of 38.5 degrees C on 14 Dec 2022 Wed, I still managed to carry out the migration.

As of 15 Dec 2022 Thursday at 4.30 PM, I still have a mild fever of 37.5 degrees C.

Below are the detailed instructions. Special thanks to Jamie Cameron at Virtualmin.com for providing guidance.

I am not migrating the slave DNS server yet. It is still running CentOS 7.9.

DETAILED INSTRUCTIONS ======================

SECTION A - Installing Virtualmin 7.0.0 on new AlmaLinux 9.1 VPS =================================================================

# wget https://software.virtualmin.com/gpl/scripts/install.sh

# /bin/sh install.sh

Running Virtualmin 7 pre-installation setup: Syncing system time .. .. done Updating CA certificates .. .. done

Welcome to the Virtualmin GPL installer, version 7.0.0

This script must be run on a freshly installed supported OS. It does not perform updates or upgrades (use your system package manager) or license changes (use the "virtualmin change-license" command).

The systems currently supported by install script are:

Red Hat Enterprise Linux and derivatives - RHEL 8 and 9 on x86_64 - Alma and Rocky 8 and 9 on x86_64 - CentOS 7 on x86_64

Debian Linux and derivatives - Debian 10 and 11 on i386 and amd64 - Ubuntu 20.04 LTS and 22.04 LTS on i386 and amd64

If your OS/version/arch is not listed, installation will fail. More details about the systems supported by the script can be found here:

https://www.virtualmin.com/os-support

The selected package bundle is LAMP and the size of install is full. It will require up to 650 MB of disk space.

Exit and re-run this script with --help flag to see available options.

Post-Installation Wizard =========================

Introduction =============

This post-installation wizard allows you to configure Virtualmin optimally for your system. You can make selections depending on whether you want to host websites, email or databases, and based on your system's memory and CPU power. To continue, click the Next button below. To skip it and use the default settings, click Cancel.

Click Next.

Memory use ===========

Virtualmin can be tuned to improve performance in its user interface and email processing, but at the cost of increased memory use. The best choice depends on how your system will be used.

Preload Virtualmin libraries? Choose Yes, faster UI with more RAM used (≈40M)

Run email domain lookup server? Choose Yes, faster mail processing with more RAM used (≈70M)

Click Next.

If your system is going to host domains that will receive a large amount of email, scanning incoming messages for viruses can generate high CPU load. Because scanning is done using the ClamAV scanning server clamd, it will consume RAM even when not processing email. If your system will not be hosting email, virus scanning can be disabled.

Enable virus scanning with ClamAV? Choose Yes, uses up to 2G of RAM

Click Next.

Spam filtering ==================

If your system is going to host domains that will receive a large amount of email, filtering incoming messages for spam can generate significant CPU load. This is due to CPU use by the SpamAssassin mail filter when it is started, which can be avoided by running the SpamAssassin filter server spamd in the background. This consumes RAM, but reduces CPU load and makes mail processing faster.

Run SpamAssassin server filter? Choose Yes, faster mail processing with more RAM used (≈30M) and no per-domain settings

Click Next.

Database servers ================

Virtualmin supports both the MariaDB and PostgreSQL database servers, but you might want to run only one (or neither) on your system. Each consumes RAM when running, even if they are not being used. Depending on the websites and applications you plan to host, running MariaDB only may be enough, as most web applications do not support or require PostgreSQL. If your system will only be used for mail or DNS hosting, there is no need to run either.

Run MariaDB database server? Yes

Run PostgreSQL database server? No

Click Next.

MariaDB password ================

To prevent other users on your system from managing the MariaDB database, a password for the root user should be set. Currently the MariaDB password is not set, which is highly insecure.

Set MariaDB password: <removed>

Click Next.

DNS configuration ==================

For DNS zones created by Virtualmin to be resolvable, the primary nameserver record for each zone must be set to something that can itself be resolved by other systems on the Internet.

Primary nameserver: ns1.turritopsis-dohrnii-teo-en-ming.com

Click Skip check for resolvability.

Secondary nameservers (optional): ns2.turritopsis-dohrnii-teo-en-ming.com

Click Next.

All done =========

Virtualmin post-installation configuration is now complete! However, you can continue with the wizard to configure optional features.

Click Next.

Password storage =================

Virtualmin gives you the option of storing plain-text passwords for virtual servers and mailboxes, or storing only one-way encrypted (hashed) passwords. Plain text passwords are more convenient, but less secure if your system is compromised. However, with hashed passwords enabled, password recovery for virtual servers will not be not possible, and database password for new servers will be different from the administration password, and will be randomly generated.

Password storage mode: Only store hashed passwords

Click Next.

MariaDB database size ======================

MariaDB can be configured to trade off memory use for performance, depending on how much RAM your system has and how heavily you expect the database to be used.

MariaDB configuration size: Keep MariaDB system defaults

Click Next.

SSL key directory ==================

Virtualmin gives you the option of keeping SSL certificates and keys in each virtual server's home directory, or another location under /etc. The former is easier to manage, but introduces the risk that server owners may cause your webserver to fail to start if they delete the certificate file.

Location for SSL certificates: Per-domain directory under /etc/ssl/virtualmin

Click Next.

Virtualmin can create a default virtual server that will serve web requests to your system that don't match any other domain. It can also be used to request a Let's Encrypt SSL certificate for use by Virtualmin's own UI.

Setup default virtual server? No, thanks

Click Next.

Additional post-installation configuration is now complete!

Click Finish.

SECTION B - Backing up Virtualmin Virtual Servers on old CentOS 7.9 VPS ========================================================================
