How to install AdminBolt on a RackNerd VPS

AdminBolt is a hosting control panel, and RackNerd lists it as a one-click app in its ctrl control panel. That means you can have a working panel without typing a single install command. This guide walks through the one-click route, what size of VPS to choose, what to do on first login, and the problems an independent reviewer ran into.

If you are new to the idea, read what is AdminBolt? first. Menus in ctrl and in AdminBolt change from version to version, so the wording on your screen may differ a little. The steps and cautions stay the same.

Before you start

Check	Why
The server is new or empty	Installing a one-click app erases the server. See RackNerd's one-click apps explained
You have a domain name	You will point it at the server. See domains and DNS explained
You know the licence terms	AdminBolt is paid software, and the terms can change. Read AdminBolt's current licence page. This guide does not quote prices
You know how you will back up	RackNerd does not include backups by default

Do not do this on a server that already hosts sites you care about. If you have one, see moving to a new VPS and build the new server alongside.

Choosing the size

AdminBolt says it uses little memory when idle, but that is a vendor claim, and a panel is only part of the load. The server also runs a web server, PHP, databases and mail. In the independent review, a 4 GB server with AdminBolt installed was using roughly 1.3 to 1.4 GB, with about 2.5 GB free. That figure included the operating system and everything else, and it was measured with almost no real traffic.

Plan	Reasonable for
2 GB	Trying the panel, or one or two very small sites. Tight once email and databases are busy
4 GB	A sensible starting point for a few small to medium sites
6 to 8 GB	More sites, busier databases, or WordPress sites with real traffic

The panel was tested on AlmaLinux 9 in the review, which is also the system AdminBolt names on its comparison page. Check AdminBolt's installation page for the supported systems before you choose, rather than assuming.

Installing with one click

1. Log in to ctrl, RackNerd's control panel, and open the server you want to use. Your welcome email has the details.
2. Open the one-click apps section and choose AdminBolt.
3. Read the warning that the server will be wiped, then confirm only if the server is empty.
4. Wait. The server is reinstalled with AdminBolt in place. Give it several minutes and refresh ctrl until it shows the server as running.
5. Find your login details in ctrl or the instructions shown on screen. If you are unsure, open a ticket with RackNerd.

The reviewer used this route and did not need an SSH session. If you prefer to install by command line, AdminBolt's documentation has an installation page. Follow it exactly and do not paste commands from anywhere else.

First login

1. Open the address shown for the panel in your browser. You may see a certificate warning at first, because the panel may start with a self-signed certificate.
2. Run the setup wizard. In the giveaway, the wizard asked for an email address to start a trial, with a confirmation link to click.
3. Set a long, unique password and keep it in a password manager.
4. If the panel offers two-factor login, turn it on.
5. Check the server's IP address in the panel's settings matches the one in ctrl. The reviewer found the panel kept an old default IP after the server's address changed, which later caused an SSL error.

Adding your first domain and site

1. Point the domain first. At your domain registrar, create an A record for the domain (and for www) pointing to the server's IP address. Wait for DNS to update, which can take from minutes to hours.
2. Add the domain in AdminBolt and create the website.
3. Request the free SSL certificate. This works only once the A record points at the server. The reviewer noted that the error message was clear when the record was missing.
4. Upload files or install WordPress using the panel's tools, then load the site in your browser to check it.
5. Test email by sending to and from an address on the domain before you trust it.

Securing the server

A control panel adds login pages that attackers will find. Do the basics too:

• Keep the panel and the system updated.
• Use SSH keys rather than a root password. See how to set up SSH keys.
• Check the firewall and which ports are open, and close what you do not need. RackNerd's ctrl also has a network firewall option.
• Use the panel's built-in protection against repeated login attempts, if it has one, and see installing fail2ban for the idea.
• Read what to do if your VPS is hacked before you need it.

Backups

The reviewer found AdminBolt's file backups and restores worked, including a safety copy made automatically before a restore. They also found that account-level backups were available but not active until a backup policy was assigned. Their test covered website files only, not databases, server settings, off-site copies or how long backups are kept.

1. Assign a backup policy and confirm a backup actually runs.
2. Do a test restore of a small site before you rely on it.
3. Keep a copy off the server. See using a storage VPS for backups.

Problems others have hit

These come from one independent review of version 1.9.2. Your version may differ.

• A DNS health check showed "healthy" for a domain that had no public address records. Do not trust it alone. Check DNS yourself.
• Entering an invalid domain produced a vague error message.
• The AI assistant reported itself unavailable even though its settings showed connected.
• The restore confirmation did not say which backup would be restored.

Troubleshooting

Symptom	Likely cause	Try
Panel does not load	Install still running, or wrong address or port	Wait, then check the server in ctrl and use the console there
SSL certificate fails	DNS not pointing at the server yet, or stale default IP in the panel	Check the A record, then the IP in the panel settings
Site shows a default page	Files uploaded to the wrong folder, or DNS still pointing elsewhere	Check the site's document root and the domain's DNS
Email not arriving	Missing mail DNS records, or the server's address is blocked or untrusted	Check the domain's mail records in the panel, and test with a new address
Server slow	Out of memory	See my VPS is slow or down

Limits

• Versions change. Screens, features and requirements may differ from this guide. Check AdminBolt's documentation.
• One independent review. The problems listed come from a single review on one server.
• Unmanaged. RackNerd provides the server, and you look after the panel, updates, security and backups.
• Email is a lot of work. Running your own mail well, with good delivery, takes care. Consider a separate mail service for important mail.
• Licence terms apply. AdminBolt's terms and RackNerd's acceptable use policy both apply to your server.

When to step up

Step up if the server runs low on memory, if you add more than a handful of sites, or if you move a large site with a big database. For a migration from cPanel, see moving an overgrown cPanel website to a VPS, which uses a hand-built server rather than a panel, and gives you a good idea of the work involved.
