1. Introduction to package Management

　　1.1 Source Package

-Script installation package

　　1.2 Binary package (RPM package, system default package)

-Dependency

2. RPM Command Management (Redhat Package Manager)

2.1 RPM Package Source: RPM package on the system CD/mnt/cdrom/packages

　　　　Mount Method:

[Email protected] cdrom]# Mkdir/mnt/cdrom
[Email protected] cdrom]# mount/dev/sr0/mnt/cdrom/
Mount:block Device/dev/sr0 is write-protected, mounting read-only

2.2 RPM Package Naming principle

　　2.3 RPM Packet Dependency: tree-dependent, ring-dependent, module-dependent (query site: www.rpmfind.net)

　　2.4 Installation command: [RPM-IVH package full Name] (-i:install,-v:verbose,-h:hash)

2.5 Example: Apache installation package Installation Example:

　　　[Email protected] packages]# RPM-IVH httpd-

httpd-2.2.15-29.el6.centos.i686.rpm

httpd-devel-2.2.15-29.el6.centos.i686.rpm

httpd-manual-2.2.15-29.el6.centos.noarch.rpm

httpd-tools-2.2.15-29.el6.centos.i686.rpm

　　2.6 Upgrade Command: [RPM-UVH package full Name] (-u:upgrade)

2.7 Uninstall command: [RPM-E package name] (-e:erase)

2.8 Query Command: [RPM-Q package name] (check if package is installed, query)

[RPM-QA Package Name] (query all installed RPM packages, all)

Example: Rpm-qa | grep httpd

[RPM-QI package name] (-I: Query software information information,-p: query for package information not installed)

[RPM-QL Package Name] (query package inside the file installation location,-L: list)

[rpm-qf System file name] (-F: Querying system files for which package filename)

[RPM-QR Package Name] (-r: Query package dependency requires)

2.9 Check command: [rpm-v package name]-v:verify)

2.10 RPM Package File extraction (remediation when system critical commands are lost)

[Rpm2cpio Package Full name | cpio-idv. File absolute Path]

-Rpm2cpio: Convert RPM package to cpio Format command

-Cpio: is a standard tool for creating software archive files and extracting files from files

Example: the treatment after LS failure

Rpm-qf/bin/ls (query which package LS belongs to)

mv/bin/ls/tmp/(cause ls command mistakenly delete illusion)

rpm2cpio/mnt/cdrom/packages/coreutils-8.4-19.el6.i686.rpm | Cpio-idv./bin/ls (extracting the LS command from the RPM package to the current directory under/bin/ls, note that the disc directory cannot be written)

cp/root/bin/ls/bin/(copy ls command to/bin/directory, repair file is missing)
