Linux rpm, yum tool usage

7.1 Three Ways to install packages:

1. RPM Tools

   
   

The RPM command is a management tool for RPM packages. RPM was originally a red Hat Linux distribution program designed to manage Linux packages and is popular because it follows GPL rules and is powerful and convenient. is gradually being adopted by other distributions. The advent of RPM suite management means that Linux is easy to install and upgrade, which indirectly increases the applicability of Linux.

2.yum Tools

Yum (full name Yellow dog Updater, Modified) is a in Fedora and Redhat and CentOS Shell Front-end package manager. Based on rpm package management, the ability to automatically download RPM packages from specified servers and install them automatically handles dependency relationships and installs all dependent packages at once, without the hassle of downloading and installing them over and over again.

3. Source code Package

Source package is open source, directly find the official website address, on the system directly link installation to the specified directory, is generally/usr/local/src/plus file name.

2. Use the mount command to mount the mirror disk to the/mnt/directory.

[[email protected] ~]# mount /dev/cdrom /mnt/      // Mount mount: /dev/sr0  write protection, will be mounted in read-only mode [[email protected]-01 ~]# cd /mnt                                 //into the/mnt directory [[email protected] mnt ]# ls                                     //View the contents of the Mount in the directory (the file used when installing the system, one of the packages files is a RPM package.) centos_buildtag  efi  eula  gpl  images  isolinux   LiveOS  Packages  repodata  RPM-GPG-KEY-CentOS-7   Rpm-gpg-key-centos-testing-7  trans.

Rpmwhich-2.20-7.el7.x86_64.rpmwhois-5.1.1-2.el7.x86_64.rpmwireshark-1.10.14-10.el7.x86_64. rpmwireshark-gnome-1.10.14-10.el7.x86_64.rpmzenity-3.8.0-5.el7.x86_64.rpm ..... The above examples are listed, not and these.

Read the characteristics of RPM package file name:

Example file: wireshark-1.10.14-10.el7.x86_64.rpm

Wireshark: Package Name

1.10.14: Version number

10.EL7: Release version number

X86_64: Platform

. RPM: Suffix name

7.3 RPM Tool Usage:

RPM-IVH RPM Package File//Installation

RPM-UVH RPM Package File//Upgrade

RPM-E Package name//Uninstall

RPM-QA//Query installed packages

RPM-Q Package Name//query Specifies whether the package is installed

RPM-QI Package name//Query Specify package information

RPM-QL Package name//list package installed files

RPM-QF file Absolute path//view which package the file was installed by

Expand Knowledge Points:

[[email protected] packages]# RPM-QF ' which CD '//When you do not know the absolute path of the file using the need to query the installation package command to use to see which package is installed

Bash-4.2.46-20.el7_2.x86_64

7.4 Yum Tool Usage:

Yum list//list available RPM packages

ls/etc/yum.repos.d///View Yum configuration file

Yum Search vim (package name)//Search Package

Yum install [-y] Package name//Use the Yum installation package, plus-y is not asked to install directly

Yum grouplist//List of groups that can be installed

Yum Groupinstall [-y] Group name//install group inside package, plus-y is not asked to install directly

Yum remove [-y] Package name//Uninstall installation package (will unload dependent packages)

Yum update [-y] Package name//upgrade installation package (if the package name is not added, the system RPM package will be upgraded to the latest, including the system)

Yum provides "/*/vim"//when the system does not have this command, you do not know the installation package, you can search through the command to see what the installation package, if the system does not have this command.

Expand Knowledge Points:

In the following example, grep is a tool that filters the specified string, and the function of | is to filter the VIM package name by the result of the Yum list output.

[[email protected] packages]# yum list |grep  ' Vim ' vim-common.x86_64                             2:7.4.160-2.el7              @basevim-enhanced.x86_64                          2:7.4.160-2.el7              @basevim-filesystem.x86_64                         2:7.4.160-2.el7            @ basevim-minimal.x86_64                           2:7.4.160-1.el7              @anacondaprotobuf-vim.x86_64                          2.5.0-8.el7                 basevim-x11.x86_64                                2:7.4.160-2.el7             basevim-minimal.x86_64                            2:7.4.160-2.el7            base

7.5 Yum to build a local warehouse:

The action Steps command is as follows:

Mount the image to the/MNT directory

Cp-r/etc/yum.repos.d/etc/yum.repos.d.bak

Rm-f/etc/yum.repos.d/*

Vim/etc/yum.repos.d/dvd.repo//content is as follows

[DVD]

Name=install DVD

Baseurl=file:///mnt

Enable=1

Gpgcheck=0

Yum Clean All

Yum List

The experimental steps are as follows:

[[email protected] ~]# cp-r/etc/yum.repos.d/etc/yum.repos.d.bak//To ensure that deleted files are not lost, first make a backup, copy the directory [[email protected] ~]# cd/e  Tc/yum.repos.d[[email protected] yum.repos.d]# Lscentos-base.repo Centos-cr.repo Centos-debuginfo.repo Centos-fasttrack.repo Centos-media.repo Centos-sources.repo ce[[email protected] yum.repos.d]# RM-RF./*//Put all repo All files are deleted [[email protected] yum.repos.d]# VI Dvd.repo//Create a Dvd.repo file, enter the following configuration information into this file, save exit.

Delete Dvd.repo This file, copy the file back.

Role: The use of local CD-ROM as a storage can be very convenient to install some dependent packages, if you do not install Yum, using RPM package installation will have a lot of dependent packages, a depends on b\b dependency C, this will be very troublesome, using the Yum local warehouse installation will be very convenient, directly to help you install.
