<\/p>\n
Prerequisites<\/strong><\/h2>\n\n- An AlmaLinux 9 server with root access or a
sudo<\/code> user. If you haven't noticed, we offer AlmaLinux servers with high reliability and availability baked in. Take a look at our offerings<\/a> and prepare for your mind to be blown \ud83e\udd2f.<\/li>\n- Access your sever via SSH, check out How to access your server using SSH<\/a> for instructions.<\/li>\n<\/ul>\n
Note<\/strong><\/h3>\nTo avoid the hassle, you can install Webmin in seconds with our 1-click Webmin application. Just choose a server<\/a>, click Customize Your Own Server<\/strong>, go to the Apps<\/strong> tab under Select Server Image<\/strong>, and select Webmin<\/strong>!<\/p><\/blockquote>\nStep 1: Updating Your System Packages<\/strong><\/h2>\nStart by checking for updates on your AlmaLinux 9 system:<\/p>\n
sudo dnf check-update<\/code><\/pre>\nIf you see a list of packages that need to be updated, then, it's a good idea to perform a comprehensive update that installs available updates:<\/p>\n
sudo dnf upgrade<\/code><\/pre>\nStep 2: Install Webmin on<\/strong> AlmaLinux 9<\/strong><\/h2>\nTo install Webmin on AlmaLinux 9, you'll install wget<\/code> , then download the Webmin repository configuration script and use it to add the official Webmin repository. Finally, you'll use the dnf install<\/code> command to install Webmin and all its necessary packages.<\/p>\nSetting up the Webmin Repository<\/h3>\n
Install wget<\/code> :<\/p>\nsudo dnf install wget<\/code><\/pre>\nOutput:<\/p>\n
![\"install](\"https:\/\/www.ssdnodes.com\/wp-content\/uploads\/2024\/11\/install-wget-1024x445.webp\")
<\/p>\n
Download the repository configuration script:<\/p>\n
sudo wget https:\/\/raw.githubusercontent.com\/webmin\/webmin\/master\/setup-repos.sh<\/code><\/pre>\nRun this script:<\/p>\n
sudo sh setup-repos.sh<\/code><\/pre>\nYou\u2019ll receive output similar to the following:<\/p>\n
![\"Setup](\"https:\/\/www.ssdnodes.com\/wp-content\/uploads\/2024\/11\/Setup-Webmin-repository-1024x249.webp\")
<\/p>\n
We can now install Webmin using the dnf<\/code> package manager.<\/p>\nInstall Webmin<\/h3>\n
After the repositories setup, you can now install Webmin:<\/p>\n
sudo dnf install webmin<\/code><\/pre>\nYou\u2019ll receive output like this:<\/p>\n

miniserv.pl<\/code> (Webmin's web server) with the PID 15358<\/code>.<\/li>\n- Tasks<\/strong>: The service is running with 1 active task.<\/li>\n<\/ul>\n
This confirms that Webmin is running correctly on your system.<\/p>\n
Setting up the Firewall<\/h3>\n
With Webmin installed, you\u2019ll need to configure the firewall.<\/p>\n
First, check whether firewall-cmd<\/code> is active:<\/p>\n$ sudo firewall-cmd<\/code><\/pre>\nOutput:<\/p>\n
State: running\r\n\r\nNo options specified\r\nusage: 'firewall-cmd --help' for usage information or see firewall-cmd(1) man page<\/code><\/pre>\nWebmin is available on the port 10000<\/code> by default. To allow this port, run the following command:<\/p>\nsudo firewall-cmd --add-port=10000\/tcp --permanent<\/code><\/pre>\nOutput:<\/p>\n
success<\/code><\/pre>\nWhile you\u2019re at it, you should also allow port 80<\/code>. This is the default HTTP port, and you\u2019ll later use it to get a Let\u2019s Encrypt<\/a> certificate.<\/p>\nsudo firewall-cmd --add-port=80\/tcp --permanent<\/code><\/pre>\nReload the firewall-cmd<\/code> to apply changes:<\/p>\nsudo firewall-cmd --reload<\/code><\/pre>\nCheck the firewall status:<\/p>\n
sudo firewall-cmd --list-all<\/code><\/pre>\nOutput:<\/p>\n

Allow only a few trusted IP addresses or IP ranges to access Webmin.<\/strong><\/p>\nAccess Webmin<\/h3>\n
With Webmin installed on your AlmaLinux 9 server, use your browser to visit the following URL:<\/p>\n
https:\/\/your_ip_address_or_domain:10000<\/code><\/pre>\nAt first, your browser will show a \"Not Secure\"<\/strong> warning, as the default HTTPS connection is relying on a self-signed<\/a> Webmin certificate. Don\u2019t worry, we\u2019ll fix this later in the article.<\/p>\n![\"webmin](\"https:\/\/www.ssdnodes.com\/wp-content\/uploads\/2024\/11\/webmin-security-warning.webp\")
<\/p>\n
Click the Advanced<\/strong> button or More information<\/strong> depending on the browser, and choose to proceed.<\/p>\nWebmin\u2019s Default Login on AlmaLinux<\/h3>\n
The default login credentials of Webmin are the same as your Unix users. You can also use the root account of your server with root<\/code> as a username and the root\u2019s password.<\/p>\nWebmin Dashboard<\/h3>\n
After you login, you\u2019ll be moved to the dashboard:<\/p>\n

<\/p>\n
Webmin is now installed on your AlmaLinux 9 server and ready for use. Next, you\u2019ll need to secure it with HTTPS by installing a Let\u2019s Encrypt SSL certificate.<\/p>\n
