You may be asked to reboot the server, which you can also do through the Webmin interface. For example, if you have Apache installed, you would find the configuration tab for it under Servers , and then Apache. Explore the interface, or read the Official Webmin wiki to learn more about managing your system with Webmin.

Ubuntu Introduction Webmin is a modern web control panel that allows you to administer your Linux server through a browser-based interface.
Prerequisites To complete this tutorial, you will need: One Ubuntu This server should have a non-root user with sudo privileges and a UFW firewall configured.
Set this up by following our Ubuntu As you follow this prerequisite guide, be sure to configure a virtual host. Open the file in your preferred editor. About the authors. Webmin behaves differently depending on the operating system or Linux distribution that you have installed, and the particular version that you are running. The correct OS is always automatically detected at installation time or provided by the installer, but it is quite possible that your system may be upgraded during the lifetime of the system.
If this happens, Webmin will not automatically detect the upgrade - you must tell it by following these steps:.
The operating system and version detected at installation time determines the default values for module configurations, as each flavor of Unix uses different locations and formats for the various config files that Webmin manages. However, changing your OS by following the steps above will not adjust any of these configuration settings.
Instead, it will just determine which ones are used for modules installed in future. Usually this is not a problem, as most OS upgrades will not change the locations of files and programs. However, some modules may need to be manually configured after an upgrade - for example, you may need to change the print system used by the Printer Administration module if the old OS version used LPRng and the new version uses CUPS.
Webmin also uses the PATH variable to locate commands that it runs when a full path is not specified, such as webalizer or mysql. Again, Webmin by default sets this variable to include all of the common library directories on your operating system, but it may miss some out if you have compiled and installed programs manually.
A symptom of this is programs run by Webmin failing with an error message like libmysqlclient. You can edit these paths and define your own environment variables that will be passed to all programs run by Webmin by following these steps:. Any program run by Webmin also has access to several variables set by the webserver itself and passed to the CGI programs that make up Webmin. Many Webmin modules have been translated into different language, such as German and Japanese.
You can change the default language for all users by following the steps below, of for just a single user in the Webmin Users module. Not all of the translations are complete, so some messages and labels will still appear in English though. Many languages such as Chinese, Japanese and Russian use symbols not found in the standard European alphabet. To display them a special font often needs to be installed on the system running the browser that you use to access Webmin.
Some Linux distributions include these fonts by default, but others do not and installing them can be rather complex. As well as general user interface settings that apply to all pages, there are some that control the layout of only the main menu on which module icons are displayed. They can be used to turn categorization off, control the display of your system's hostname and OS and have users sent directly to a module by default, among other things. These steps explain how to change the main menu settings :.
Some non-standard themes may not implement all of these features, especially those that have their own main menus. Webmin has the ability to upgrade itself when a new version comes out, either from a file that you have already downloaded or from a package that it fetches from www.
Even though it is quite possible to upgrade from the command line by installing the latest RPM or tar. Webmin can only be upgraded using the same type of package that it was originally installed from. This means that if you used the tar. Of course, when Webmin downloads the newest version for you it will always choose the right package format. This can only be done if you have the gpg command installed on your system, and when using the tar.
Signature checking protects you from installing a fake versions of Webmin that is actually a Trojan horse or some other type of malicious program. The upgrade process will preserve all users and module configuration settings, and should not even be noticeable by people currently accessing your Webmin server. If you originally installed the program from the tar. For example, if Webmin 1. Any modules that the new version includes but the old one does not will be granted to the first user listed in the Webmin Users module, which will typically be root or admin.
You should check after the upgrade is complete to ensure that they have not been given to an un-trusted user instead though, as most modules by default can be used to subvert security on your system. Updated versions of Webmin modules in the latest release are often made available to fix bugs or security problems.
Installing these updated modules is always a good idea, as they may fix problems that you have been having or patch security holes that could allow un-trusted users to gain root access on your system. Updates are always designed to solve problems rather than adding new features which may potentially have problems of their own. Of course, if you are not having any trouble then you can just wait until the next full release and install it instead.
Each version will always include any updates that were made available for previous versions of Webmin. Updates are only created to solve problems in the latest version, so if you are running an older version do not expect any more to be released for it. You can retrieve any that you need from there to be installed using this module, as explained in the Installing and deleting Webmin modules section.
However, there is an easier method - Webmin can be told to check for, download and install any updates that it does not already have. This can either be done explicitly using this module, or set up to happen on schedule. Every Webmin module has a version number, which the update process uses to keep track of which ones it has already downloaded and installed.
A message like Module cron is already up to date shown next to a potential update indicates that it has already been installed. Instead of manually following the steps above every now and then, you can configure Webmin to check for, report on and install new modules on schedule. When needed updates are found, an email can be sent to you listing the modules that should be or have been installed and the problems that they fix.
As well the email will include notification of the availability of a new Webmin release, if there is one. Automatic updating can be turned off at any time by de-selecting the Scheduled updating currently enabled box on this form and clicking on Save and Apply. Webmin has several options that control how multiple failed login attempts are handled, how users login and how Unix passwords are checked. The default authentication method uses cookies, but if your browser cannot handle them you may want to switch to basic HTTP authentication instead.
The only problem with this method is that there is no way to properly log out, as there is no support for logging out in the HTTP protocol. Two-factor authentication can be used to add an extra layer of security to a Webmin account, as well as the regular username and password. When enabled, a user will need to provide an extra authentication token which typically comes from a smartphone app, hardware OTP generator or SMS.
This page allows you to select an authentication provider for Webmin users on your system. Ask Question. Asked 2 years, 7 months ago. Active 1 month ago. Viewed 1k times.

Thank you — ajcg. Now test your method. I can not install the module via command line which is what I ask. The "howto" you put in your answer are for GUI. Anyway, I appreciate your explanation — ajcg. Even though your answer does not answer the question, the explanation is very good and illustrative and complements the question. Thank you for your contribution — ajcg.
