Most readers may have experience installing DOS and WINDOWS, but installing LINUX is much more complicated than they do. You must have a certain understanding of the computer and be careful to protect your data, be careful not to press the button at will.
　　
Here, I will introduce you to RED HAT LINUX. Red HAT, which is located in North Carolina, has been striving to make Linux better available since its launch in the summer of 1994, so far, Red Hat Linux has become the best Linux release version. It supports more hardware and has higher reliability. Unlike other Linux releases, Red Hat Linux is based on a package, each package provides a fully tested, configured, ready to run software. If you want to try a new editor and install it, you can use it in a few seconds. Do you want to delete it? A simple command can make it disappear.
　　
Linux software development is fast, and even the core is the same. Therefore, a new version will appear soon after a release. Now, what did you do when you upgraded from Windows 3.1 to 95? The best case is to reload all applications, or delete everything on the hard disk, and start over again. This is quite troublesome, but if you use Red Hat Linux, you don't have to. It is very easy to upgrade based on the package, and you don't even need to restart your machine. Red Hat Software will always provide more convenient Software for users who are using Linux.
　　
This article will introduce how to configure the Linux server and its applicable environment through a theoretical and practical method, quickly Become the administrator of a Linux Server.
　　
The following describes how to configure the software on the server and how it works:
　　
Apache, dhcp, dns, ppp, sendmail, samba, squid, isdn, mysql, tomcat, and php.
　　
These configurations basically cover all the services required by a small and medium-sized enterprise to manage and work. That is to say, if you have mastered their configuration solutions and management methods, you will become a qualified Linux Server administrator for small and medium-sized enterprise LAN. It should be emphasized that there are too many configuration items in these configuration files, many of which cannot be used, so in future articles, I will introduce the important configuration items.
　　
TIPS:
　　
1. You can use rpm-qf named. conf to query which RPM package the file belongs.
　　
2. You can use the rpm-qpl caching-nameserver-6.2-2.noarch.rpm to view which files are contained in an RPM package.
　　
3. you can use grep '^ [A-Z]' httpd. conf to remove comments from a configuration file, because most configuration file configuration items start with an uppercase letter, therefore, you only need to skillfully use the grep parameter to export the rows starting with an upper-case letter A-Z to a file, but if the configuration file contains a configuration item starting with a lower-case letter, like named. conf cannot be used.
　　
4. You can run ntsysv in Linux to select the service project started by the server.
　　
Note: In most releases of Linux, I think RedHat is preferred in the release regardless of the stability and ease of use of the system to a wide range of applicability, so in the following article, I will take RedHat 6.2 as an example to help you become an outstanding Linux Server Administer.
