Linux under RPM Package Management command detailed

Basic concepts of software under 1.linux

Important files that the program needs to use: configuration files, instructions, library files, help information

/etc,/bin,/sbin,/lib,/usr/share/man

1.1. The program path required to start the system must be on the partition of the root file system

/etc,/bin,/sbin,/lib,/usr/share/man

1.2. The operation required after system startup as the core function of the system or the necessary function program path

/etc,/usr/bin,/usr/sbin/,/usr/lib,/usr/share/man

1.3. User-installed third-party programs required additional function program path, not related to operating system startup, etc.

/usr/local/etc,/usr/local/bin,/usr/local/sbin,/usr/local/lib,/usr/local/man

2.RPM called Package Manager

The RPM package consists of the main package and the child package, named in the following format

name-version-release2.arch.rpm

Version:major.minor.release1

namely name-major.minor.release1-release2.arch.rpm

such as:kernel-2.6.18-308.el5.i686.rpm

Name: Package name--kernel

Major rep: Major version number, significant improvements--->2

Minor representative: Minor version number, a major change in a sub-function--->6

Release1 on behalf of the release number, fixed some bugs, adjusted a little function--- >

RELEASE2 represents two releases--->308

Arch: Platform--->i686

RPM Package: Is the author download the source program, compiled configuration completed, made into RPM package, belongs to the binary format

3. Installation, the need to handle the dependencies between RPM packages

Format: rpm-i RPM package Full path name

-H: Show progress by #, each # represents 2%;

-V: Show detailed procedures

-VV: A more detailed process

RPM-IVH RPM Package Full path name

--nodeps: Ignoring dependencies;

--replacepkgs: Re-install, replace the original installation;

--oldpackage: Downgrade

--force: Forced installation, can be re-installed or degraded;

4. Enquiry

Format: rpm-q only RPM Package name: Query whether the specified package is already installed

Example: Rpm-q httpd

RPM-QA: Querying all packages that have been installed

Rpm-qi only RPM Package name: Query the description information of the specified package;

RPM-QL only RPM Package name: Query the list of files generated after the installation of the specified package;

RPM-QC only RPM Package name: Query the configuration file for the specified package installation;

RPM-QD only RPM Package name: Query the Help file for the specified package installation;

Rpm-q--scripts only RPM package name: Query the script contained in the specified package

RPM-QF specific file path name: The query specifies which RPM package the file is generated from;

Example: RPM-QF/ETC/PASSWD

If a RPM package has not been installed, we need to query its description information, installation will be generated after the file;

Format: Rpm-qpi RPM Package Full pathname Query No description information for packages installed;

RPM-QPL RPM Package Full path name query the list of files that are not installed for the package to be generated

5. Upgrade

Format: RPM-UVH RPM Package Full path name: If the old version is installed, then upgrade;

RPM-FVH RPM Package Full path name: If the old version is installed, upgrade; otherwise, exit;

--oldpackage: Downgrade

6. Uninstall

Format: rpm-e RPM package Name only

--nodeps

Example: Rpm-e httpd

7. Check: Whether the package after installation has been modified by someone

format:rpm-v RPM Package name only

For example: Rpm-v httpd If there is no return information to prove that the installation package is normal without being modified.

8. Verify the legality of the source and the completeness of the package;

Redhat Public Key storage path:/etc/pki/rpm-gpg/rpm-gpg-key-redhat-release

RPM--import/etc/pki/rpm-gpg/rpm-gpg-key-redhat-release: Import Key file

Rpm-k RPM Package Full path name

DSA, GPG: Verifying the legitimacy of the source, that is, the verification of the signature; you can use--nosignature to skip this

SHA1, MD5: Verifying package integrity; You can use--nodigest to skip this

Example: Rpm-k httpd-2.2.3-63.el5.i386.rpm

Rpm-k--nodigest httpd-2.2.3-63.el5.i386.rpm

9. Rebuilding the database

RPM--REBUILDDB: Rebuilding the database will be re-established;

--INITDB: Initialize the database, there is no build, no is established
