Article Title: install three major software packages: rpm1_tar.gz1_tar.bz2. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems, open-source and other basic categories 1. Install using RPM software packages
　
When talking about RPM (REDHAT Package Management) standard software packages, everyone may think of the well-known REDHAT company. It is the release method of RPM software packages that makes installation of application software in Linux easy. If you want to install software released in RPM mode, simply enter the command "rpm-ivh xxx. rpm.
　
For example, if you want to install the OpenOffice.org-1.0.1.rpm package, you only need to enter the command "rpm-ivh OpenOffice.org-1.0.1.rpm. Another advantage of the RPM package release method is that it can easily Delete installed RPM packages, run the "rpm-e OpenOffice.org-1.0.1" command to safely and permanently delete the installed OpenOffice.org-1.0.1.rpm from the hard disk. If you install/delete software in the X-Window environment, there is a better solution. If you use KDE, you can use the Kpackage program that comes with KDE to add or delete the software. If you use GNOME, you can use the Gnorpm program to manage the software. Both programs are similar to the "Add/delete programs" function in Microsoft Windows. The software released using RPM software packages is the easiest to install and manage. We recommend that you use this mode to manage the software in the future.
　
2.Tar.gz (Tgz) software package installation
　
A software package with the extension tar.gz is a package packaged with the Tar program and compressed with the Gzip program. To install such a software package, you must decompress the package first. You can use tar-zxfv filename.tar.gz to decompress the package. The extracted files are in the directory named Filename. Go to the directory to view the extracted files.
　
Various software have different installation methods, but generally each software package has an Install and Readme file after being decompressed. The help file provides detailed installation instructions. A disadvantage of software released using the tar.gz (or Tgz) package is that there is generally no anti-installation program. If you need to delete the installed software, you have to carefully check the installation path and file name in Makefile, which is difficult for beginners.
　
3.Tar.bz2 software package installation
　
A software package with the extension Tar.bz2 is packaged with the Tar program and compressed with the Bzip2 program. It has the advantage that the compression rate is very high and requires "bunzip2 filename.tar.bz2" for decompression. However, the Software Package released in this formula has the same disadvantage as the tar.gz software package, that is, it is very troublesome to delete the software package.
