Fedora/Redhat install and update the software package online yum

Fedora/Redhat online installation and update package yum this article describes how to install and update the software online using the Fedora core 4.0 software package management tool yum, we will introduce it in another article. 1. Use of yum. Some new Linux beginners may ask why you don't need to upgrade the system's built-in graphical tool up2date, but use yum. As a matter of fact, we can see from the very beginning that up2date is incredibly slow and often gets lost in response, resulting in the situation where machines are suspended. Therefore, we should try yum. In addition, freshrpms.net may update the source faster than the official site, and there is no reason not to use yum; 1. First, we need to download the yum version corresponding to our system at the following address; http://ayo.freshrpms.net/For example, I use Fedora core 4.0 to download the following package installation; [root @ localhost beinan] # rpm-ivh freshrpms-release-1.1-1.fc.noarch.rpmwarning: freshrpms-release-1.1-1.fc.noarch.rpm: Header V3 DSA signature: NOKEY, key ID e42d547bPreparing... ######################################## ### [100%] 1: freshrpms-release ## ######################################## # [100%] 2. Software Installation example; for example, I want to install a bmp-mp3 that can listen to mp3, just enter the following command line, the system will work on its own; [root @ localhost beinan] # yum install bmp-mp3 content panorama is as follows: [root @ localhost beinan] # yum install bmp-mp3Setting up Install ProcessSetting up repositoriesupdates-released 100% |================ ====| 951 B 00: 00 extras 100% | =============================| 1.1 kB 00: 00 base 100% | =============================| 1.1 kB 00: 00 freshrpms 100% |===============================| 951 B 00: 00 Reading repository metadata in from local filesprimary.xml.gz 100% |=================| 42 kB 00: 03 freshrpms: ######################################## ######### 122/122 Added 122 new packages, deleted 0 old in 0.72 secondsParsing package install argumentsResolving Dependencies --> Populating transaction set with selected packa Ges. please wait. ---> Downloading header for bmp-mp3 to pack into transaction set.bmp-mp3-0.9.7-1.2.fc4.i38 100% | ==================== | 2.9 kB ---> Package bmp-mp3.i386 0: 0. 9.7-1.2.fc4 set to be updated --> Running transaction check --> Processing Dependency: libid3-3.8.so.3 for package: bmp-mp3 --> Processing Dependency: libbeep. so.2 for package: bmp-mp3 --> Processing Dependency: bmp> = 0. 9.7 for package: bmp-mp3 --> Restarting Dependency Resolution with new changes. --> Populating transaction set with selected packages. please wait. ---> Downloading header for id3lib to pack into transaction set. id3lib-3.8.3-11.fc4.i386. 100% | =================================| 38 kB ---> Package id3lib. i386 0: 3. 8.3-11. fc4 set to be updated ---> Downloading header for bmp to pack into transaction set.bmp -0.9.7-10. fc4.i386. rpm 100% | =================================| 14 kB ---> Package bmp. i386 0: 0. 9.7-10. fc4 set to be updated --> Running transaction checkDependencies Resolved ====================== ========================================================== ======= Package Arch Version Repository Size ========================== ========================================================== =========== Installing: bmp-mp3 i386 0.9.7-1.2.fc4 Freshrpms 95 kInstalling for dependencies: bmp i386 0.9.7-10. fc4 extras 912 k id3lib i386 3.8.3-11. fc4 extras 752 kTransaction Summary ==================================== ========================================================== = Install 3 Package (s) update 0 Package (s) Remove 0 Package (s) Total download size: 1.7 MIs this OK [y/N]: yDownloading Packages: (1/3 ): id3lib-3.8.3-11.fc 100% | =================================| 752 k B (2/3 ): bmp-0.9.7-10.fc4.

Note: yum advantages: Software Package dependencies are resolved by themselves, such as the above, we can see that originally we only install bmp-mp3, the result of yum installation also installed id3lib; bmp 2. A small usage of yum; 1. query a software package; we may not be able to start with thousands of software programs, and sometimes do not know the file name. query is required at this time; we can use the yum list to list the packages on the yum upgrade source. Then we can check the following combinations of info; [root @ localhost beinan] # yum list | more: add an MPS queue. | click more to display all packages on pages. Click the Space key to view the next page. The displayed Software List contains the software name, version, installation, and so on. Take a closer look. Just get familiar with it. There is no difficulty.

If the display is: Repo: installed, Indicates that it has been installed. To query a software package, you can also add the grep parameter. For example, if we want to query whether a new kernel version is available on the upgrade source, we can use the following command to query it; of course, you can also use [root @ localhost beinan] # yum search kernel | more, that is, the parameters provided by yum -- help; [root @ localhost beinan] # yum list | grep kernel: [root @ localhost beinan] # yum list | grep kernelGFS-kernel.i686 2.6.11.8-20050601.1526 installedcman-kernel.i686 2.6.11.5-20050601.1526 installeddlm-kernel.i686 2.6.11.5-20050601.1526 installedgnbd-ke Rnel. i686 2.6.11.2-20050420.1331 installedkernel. i686 2.6.11-1.1369 _ FC4 installedkernel-devel.i686 2.6.11-1.1369 _ FC4 installedkernel-doc.noarch 2.6.11-1.1369 _ FC4 installedGFS-kernel.i586 2.6.11.8-20050601.1526 baseGFS-kernel-debuginfo.i686 2.6.11.8-20050601.1526 updates-releasedGFS-kernel-debuginfo.i586 2.6.11.8-20050601.1526 updates-releasedGFS-kernel-smp.i686 2.6.11.8-20050601.1526 baseGFS-kerne L-xen0.i686 2.6.11.8-20050601.1526 baseGFS-kernel-xenU.i686 2.6.11.8-20050601.1526 basecman-kernel.i586 2.6.11.5-20050601.1526 updates-releasedcman-kernel.i686 2.6.11.5-20050601.1526 updates-releasedcman-kernel-debuginfo.i586 2.6.11.5-20050601.1526 updates-releasedcman-kernel-debuginfo.i686 2.6.11.5-20050601.1526 updates-releasedcman-kernel-smp.i686 2.6.11.5-20050601.1526 updates-releasedcman-kern El-xen0.i686 2.6.11.5-20050601.1526 updates-releasedcman-kernel-xenU.i686 2.6.11.5-20050601.1526 updates-releaseddlm-kernel.i686 2.6.11.5-20050601.1526 updates-releaseddlm-kernel.i586 2.6.11.5-20050601.1526 updates-releaseddlm-kernel-debuginfo.i586 2.6.11.5-20050601.1526 updates-releaseddlm-kernel-debuginfo.i686 2.6.11.5-20050601.1526 updates-releaseddlm-kernel-smp.i686 2.6.11.5-20050601.1526 upda Tes-releaseddlm-kernel-xen0.i686 2.6.11.5-20050601.1526 updates-releaseddlm-kernel-xenU.i686 2.6.11.5-20050601.1526 updates-releasedgnbd-kernel.i686 2.6.11.2-20050420.1331 updates-releasedgnbd-kernel.i586 2.6.11.2-20050420.1331 updates-releasedgnbd-kernel-debuginfo.i586 2.6.11.2-20050420.1331 updates-releasedgnbd-kernel-debuginfo.i686 2.6.11.2-20050420.1331 updates-releasedgnbd-kernel-smp.i686 2.6. 11.2-20050420.1331 updates-releasedgnbd-kernel-xen0.i686 2.6.11.2-20050420.1331 updates-releasedgnbd-kernel-xenU.i686 2.6.11.2-20050420.1331 updates-releasedkernel.i586 2.6.12-1.1398 _ FC4 updates-releasedkernel.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-debuginfo.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-debuginfo.i586 2.6.12-1.1398 _ FC4 updates-releasedkernel-devel.i586 2.6.12-1.1398 _ FC4 up Dates-releasedkernel-devel.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-doc.noarch 2.6.12-1.1398 _ FC4 updates-releasedkernel-smp.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-smp-devel.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-xen0.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-xen0-devel.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-xenU.i686 2.6.12-1.1398 _ FC4 updates-releasedkernel-xenU-devel. I686 2.6.12-1.1398 _ FC4 updates-released does show a lot of kernel-related information. installed indicates that our system has been installed. Let's look at the previous column, take a look at the name to guess it. For example, doc must be related to the kernel documentation; smp is the multi-processor kernel; others I don't understand, for more information, see info. For example, if we use a single-processor X86 machine, check whether a new kernel is available. So let's try this. Check whether a new kernel can be upgraded.
