How To Install and Use Webmin on Rocky Linux 9?

To set up Webmin, you must access to your server as a root user and set up a basic firewall. For this purpose, you can visit this guide on Initial Server Setup with Rocky Linux 9.

Now follow the steps below to complete this guide.

Step 1 – Import Webmin GPG Key

Webmin packages aren’t available in the default Rocky Linux 9 repository. Here you need to import the Webmin GPG key to your server by using the command below:

# wget https://download.webmin.com/jcameron-key.asc
# rpm --import jcameron-key.asc

Step 2 – Add Webmin Repository on Rocky Linux 9

At this point, you need to add the Webmin repo by creating a Yum repository file. To do this, run the following command:

cat << EOF > /etc/yum.repos.d/webmin.repo
[Webmin]
name=Webmin Distribution Neutral
#baseurl=https://download.webmin.com/download/yum
mirrorlist=https://download.webmin.com/download/yum/mirrorlist
enabled=1
gpgkey=https://download.webmin.com/jcameron-key.asc
gpgcheck=1
EOF

When you are done, run the system update with the following command:

dnf update -y

Step 3 – Webmin Installation on Rocky Linux 9

Now you can easily run the command below to install Webmin. Also, you must install Perl because Webmin is based on Perl.

dnf install perl webmin -y

Note: During the installation, all dependencies should be resolved automatically.

Step 4 – Check Webmin Status

Webmin must be started and enabled by default. Verify that your Webmin service is active and running on Rocky Linux 9 y using the following command:

systemctl status webmin

Output
● webmin.service - Webmin server daemon
     Loaded: loaded (/usr/lib/systemd/system/webmin.service; enabled; vendor pr>
     Active: active (running) since Sat 2023-04-03 03:46:20 EST; 6s ago
    Process: 71258 ExecStart=/usr/libexec/webmin/miniserv.pl /etc/webmin/minise>
   Main PID: 71259 (miniserv.pl)
      Tasks: 4 (limit: 23609)
     Memory: 54.3M
        CPU: 4.520s
     CGroup: /system.slice/webmin.service
...

Step 5 – Configure Firewall for Webmin

By default, Webmin listens on port 100000. You can check it using the following command:

ss -antpl | grep 10000

You should see the following output:

Output
LISTEN 0      4096         0.0.0.0:10000      0.0.0.0:*    users:(("miniserv.pl",pid=71259,fd=5))

Now you need to allow Webmin port 10000 through the Rocky Linux firewall with the following command:

firewall-cmd --add-port=10000/tcp --permanent

To apply the new rules, reload the firewall:

firewall-cmd --reload
