Install and uninstall the rpm package in linux, the yum method, and the rpmyum

There are three methods for installing software in linux:

Install the rpm package, use the rpm tool to install the software package yum, use the yum command to automatically install the software package source code package, download the source code package, and compile and install the software

Rpm tool usage

1. Check whether the rpm is installed: rpm-qa | grep lvm (lvm is the rpm package name to be queried)

[Root @ hzclov51 ~] # Rpm-qa | grep lvm

Mesa-private-llvm-3.3-0.3.rc3.el6.x86_64

Lvm2-libs-2.02.100-8.el6.x86_64

Lvm2-2.02.100-8.el6.x86_64

System-config-lvm-1.1.12-16.el6.noarch

2. query the files contained in an rpm:

[Root @ hzclov51 ~] # Rpm-ql lvm2-2.02.100-8.el6.x86_64.

/Etc/lvm

/Etc/lvm/archive

/Etc/lvm/backup

/Etc/lvm/cache

/Etc/lvm/cache/. cache

3. query which rpm package a file belongs:

[Root @ hzclov51 ~] # Rpm-qf/etc/lvm

Lvm2-2.02.100-8.el6.x86_64

4. query which packages are dependent on an rpm package.

[Root @ hzclov51 ~] # Rpm-q -- whatrequires device-mapper-persistent-data

Lvm2-2.02.100-8.el6.x86_64

5. query the content on which an rpm package depends

[Root @ hzclov51 ~] # Rpm-qR lvm2-2.02.100-8.el6.x86_64.

6. query rpm package information

[Root @ hzclov51 ~] # Rpm-qi lvm2-2.02.100-8.el6.x86_64

9. Uninstall rpm

Rpm-e xxx. rpm

Usage of yum Tool

1. Basic yum commands

Yum list # list all available software packages

Yum install # install the software package

Yum grouplist # list all software groups

Yum groupinstall # Install software group

Yum remove # uninstall software

Yum update # Upgrade the software. If the package name is not added, all the software in the system will be upgraded, including the system

Yum provides "/*/vim" # search for software packages using vim commands

2. configuration file of yum Source

[Root @ localhost ~] # Ls/etc/yum. repos. d/# store the yum configuration file in this directory

CentOS-Base.repoCentOS-Debuginfo.repoCentOS-Media.repoCentOS-Vault.repo

CentOS-CR.repoCentOS-fasttrack.repoCentOS-Sources.repo

3. yum search software package

[Root @ localhost ~] # Yum search vim # search for vim-related software packages

Build a local repository using yum

1. Mount the optical drive to the mnt directory.

2. First back up the yum configuration file cp-r/etc/yum. repos. d/etc/yum. repos. d. bak/

3. Go to the yum. repos. d directory and delete all files. [root @ localhost ~] # Cd/etc/yum. repos. d # Enter yum. repos. d directory [root @ localhost yum. repos. d] # lsCentOS-Base.repoCentOS-Debuginfo.repoCentOS-Media.repoCentOS-Vault.repoCentOS-CR.repoCentOS-fasttrack.repoCentOS-Sources.repo [root @ localhost yum. repos. d] # rm-rf. /* # delete all objects

4. Create a file dev. repo [root @ localhost yum. repos. d] # vim dev. repo

# Write the following content into dev. repo: [dvd] # repository name = install dvd # customize a description string baseurl = file: /// mnt # rpm position enable = 1 # available gpcheck = 0 # detect

5. Clear the previous yum cache, yum clean all [root @ localhost yum. repos. d] # yum clean all

6. You can use yum to install the local software package.
