Webmin: Efficient Linux GUI Management

Article Title: Webmin: Efficient Linux GUI management. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Recently, Linux administrators, especially those who are familiar with Windows NT/2000 GUI, often confused about where to manage key programs and services in Linux. In this article, we will focus on the Web-based GUI Webmin, which is a useful and efficient system for managing Linux servers. We will have a comprehensive understanding of the basic methods for installing and using Webmin, as well as some of the most significant and convenient features.

Start

Currently, Webmin is one of the default configurations of many Linux versions. To check whether Webmin has been installed in your Linux system, open a browser window from Xwindows and go to http: // 127.0.0.1: 10000 (or https: // 127.0.0.1: 10000 to check whether you include the 128-bit encrypted version ). If the logon interface you see is similar to figure A, you have installed Webmin.

If you do not enter the logon page, download the appropriate rpm or compressed file and install it on Linux. If you want to use Webmin to remotely manage your Linux server, you should also set 128-bit encryption for Webmin through SSL.

Once Webmin is installed, open your browser again and go to http: // 127.0.0.1: 10000. (You may use the local host name or the Linux server host name instead of 127.0.0.1 .) In the logon prompt, enter the root user name and password. This will take you to the Webmin homepage (image B), where you can access all the configuration parameters related to Webmin and quickly browse all the included tools.

The Configuration button of Webmin will show you several useful options. Click the Upgrade Webmin button to automatically Upgrade your Webmin function and select the latest version from www.webmin.com.

In the Webmin configuration section, you can use the IP address access control mode to control the access to the Webmin server. You can also customize the settings and the appearance of Webmin. Since there are a large number of options, I suggest you familiarize yourself with them as much as possible and learn which one is more useful to you by reading their overview.

The Webmin tool has a wizard-like interface that provides help and explanation for many configurations you can modify using the tool. However, if you accidentally do something wrong, check the Webmin wizard. This reference is useful for beginners and advanced Webmin users.

　Further research Configuration

After browsing the Webmin configuration section, you can learn more about other important parts of Webmin that can be used to manage Linux servers. These parts include:

System

Server

Hardware

Others

Note that Webmin versions for different Linux and UNIX versions may include additional tabs such as networks and strings. The system and server tabs contain the most extensive content, and may be the two most frequently used tabs in the future.

The system tab (Graphic C) contains many useful system management tools that can be used to assist hard disk work, run programs, manage users and groups, arrange tasks, monitor system logs, and so on.

Server tabs provide access to management modules of servers such as Apache, Samba, Squid, BIND, Sendmail, and DHCP. Remember to install the software before using these modules.

The hardware tab can be used to manage printers, install Linux RAID, Configure Lilo, install and debug hardware drives and disk partitions, configure network services, and set system time. Be careful when using these hardware tools. If you do not know the features of the hardware contained in this module, data may be lost. When you adjust the hardware driver settings, if you are using the Edit IDE Parameters tab, make sure you have selected the hyperlink for each setting and carefully read the suggestions. This can avoid mistakes and provide you with many ways to improve IDE performance. For example, I detected my Western Digital Drive in settings and found that the buffer speed was 24.15 MB/second, and the maximum speed was 185.51 MB/second. After a few adjustments, the buffer speed is 24.24 Mb/s, and the maximum speed is 191.04 Mb/s. Although this change is not significant, it is only a simple operation that can obtain additional performance. I am very willing to do this.

Among other tabs, you will find a variety of configuration tools, some of which may be very useful to you. It should be reiterated that these depend on the Webmin version you are using and your Linux/UNIX Version. However, you should be able to see the file manager. This Windows Resource Manager mode browser can be used to view, edit, add, or delete any files on the server, it is a command interpreter used to execute a single command and is connected to the server status. This Browser allows users to customize and provides a good way to monitor server software.
