This article introduces the relevant knowledge of "what is the management method of RHEL7 software package". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

# rpm

Purpose: manage rpm packages

Syntax: rpm [options] package name

Mount the CD

[root@localhost ~] # umount / dev/sr0

[root@localhost ~] # mount/dev/sr0 / mnt/

Check the number of packages

[root@localhost ~] # cd/mnt/Packages/

[root@localhostPackages] # ls | wc-l

4621

Take out a bag and state the format of the bag.

Zsh-5.0.2-14.el7.x86_64.rpm

Zsh-5. 0.2-7 x86 64

Software name major version number minor version number revision number RHEL7 CPU architecture platform support system digits

El7: Enterprise Linux 7 RHEL7 or CentOS7

El6

El5

Install rpm softwar

[root@localhost ~] # rpm-ivh / mnt/Packages/lrzsz-0.12.20-36.el7.x86_64.rpm

[root@localhost ~] # rpm--help

-I,-install install package (s)

-v,-- verbose detailed providemore detailed output

-h,-- hash print hash marks aspackage installs (good with-v) # print hash mark # during installation

When installing, resolve dependencies:

[root@localhost] # rpm-ivh / mnt/Packages/mariadb-server-5.5.44-2.el7.x86_64.rpm-- nodeps

Method 1: find the package that starts with perl-DBD-MySQL directly

[root@localhostPackages] # rpm-ivh perl-DBD-MySQL

Method 2: download the package from the website related to the rpm package

Http://rpmfind.net/

Http://rpm.pbone.net/

Http://www.rpmseek.com/index.html

Rpm query function

[root@localhost ~] # rpm-q zsh # query whether a single zsh package is installed

Zsh-5.0.2-14.el7.x86_64

[root@localhost ~] # rpm-qa | grep httpd # query whether httpd-related software packages are installed

[root@localhost ~] # rpm-ql zsh | more

(those files and directories are generated after querying the installation of the zsh software.)

Which package installed the zsh command?

[root@localhost ~] # rpm-qf `which zsh`

Zsh-5.0.2-14.el7.x86_64

Check before the software is installed

[root@localhost ~] # rpm-qpl / mnt/Packages/lrzsz-0.12.20-36.el7.x86_64.rpm

Rpm package upgrade:

[root@localhost ~] # rpm-Uvh / mnt/Packages/lrzsz-0.12.20-36.el7.x86_64.rpm

4 uninstall the rpm package:

[root@localhost ~] # rpm-e zsh only writes the name of the software package, not the software package

Forced unloading

[root@localhost] # rpm-e mailcap-force

When you import RPM-GPG-KEY to install the rpm package, verify the signature of the rpm.

[root@localhost ~] # rpm--import/etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

[root@localhost ~] # rpm-ivh / mnt/Packages/zsh-5.0.2-14.el7.x86_64.rpm

Preparing... # # [100%]

Package zsh-5.0.2-14.el7.x86_64 isalready installed

The principle of verification is: asymmetric encryption. Import the public key. Verify that the signature in rpm is correct.
