Yellowdog Updater,modified is an RPM-based management tool written in Python to address the dependencies of RPM packages

How Yum works:

2 parts of the Software warehouse (repository)

Packages:

Various RPM packages

Repodata:

Package related files + Dependency information Database + Package list + Package Group list file

Shared File Protocol

Ftp

http

[name can not have space]

Name= this a local repository

BaseURL =FILE:///MEDIA/CD

Gpgcheck=0 0 is not enabled certificate, enable certificate to configure the next parameter more

Gpgkey= local file:///address or HTTP//address

Enabled=1 default is 1 enabled to turn off if configured to 0

Yum Management software

Query Yum Info/list

Installing yum install plus-y default auto-Confirm installation

Re-install Yum reinstall

Upgrade Yum Update

Uninstalling Yum Remove

Yum Clean all replace the warehouse with

Yum Repolist Cache repository files

Yum groupinfo ' xxx ' package group information view

Yum groupinstall ' xxx ' install package group

Yum groupremove ' xxx ' remove package group

Common package groups: ' X Window System ' graphical framework

' Desktop ' or ' KDE desktop '

' Development Tools ' development package Group

Rpm-q XXX query XX software name

RPM-QA Query all package information information

RPM-QF FILE View Package path

RPM-QL Software Name

Rpm-qpi add p to view not installed

RPM Install XXX equates to rpm-i xxx

-v Verbose Show command execution process information

-H Hash to # Show installation progress

RPM-IVH file/Path Tab completion full file name and dependent package

RPM Update/upgrade RPM-UVH and RPM-UVH

Kernel upgrade is not UVH way, but IVH way to upgrade UVH is to overwrite the installation IVH is to keep the old kernel install another kernel file

RPM-E Software Name Erase

Library functions: Static library functions, dynamic library functions

sudo wget download the address to download the file

TAR-XF filename Extract File

Management tools:

RPM Package Manager manages RPM-formatted packages for Rhel, CentOS, fedora, etc.

DBKG (Debian package) manages the Deb-formatted packages for Debian, Ubuntu hairstyle versions

The dependencies of the package are present regardless of RPM or dpkg

RPM Package Naming rules

wireshark-1.8.10-17.el6.amd64.rpm

Wireshark is the software name

1.8.10 is the software version

17 is the version revision number

EL6 is the applicable system

X86_64 CPU Architecture

32-bit CPU i386 i686

64-bit X86_64/AMD64

ARM Mobile CPU Architecture

The architecture of SPARC Sun's minicomputer

Noarch architecture Independent (32/64 bits can be installed)

RPM Package Creation Instruction Rpmbuild

RPM--import Import Certificate

When the user installs the RPM command to install the RPM package, the system detects the consistency of the system certificate and RPM package certificate, consistent with the official source, not the third party organization

192.168.*.*/* Private Address

172.16.*.*/* Private Address

10.0.0.0/* Private Address

VM Virtual Machine Networking-access the extranet through NAT (Netwwork address transformation) technology to return information because the extranet server does not have the corresponding address routing table information, does not make the conversion packets cannot be returned by the original path will be discarded

VM Virtual machine Networking path--VM host---vmnet8 (VM virtual machine)----The Vmnet8--nat conversion address of the Windows system--extranet router

The bridge mode IP address of the VM virtual machine is the same as the IP of Windows

Configure IP Address Example: 192.168.1.1 server IP address automatically assigns 192.168.1.2 to the address after the gateway is assigned to the required machine

Route-n Viewing routing table information

CAT/ETC/RESOLV.CONF viewing network card configuration information

Bootproto=static in eth0 config file is static address DHCP is dynamic address auto-assignment

ipaddr=172.15.15.186 Strictly case-sensitive

netmask=255.255.0.0 Subnet Mask

gateway=172.15.15.195 Gateway

SSH [email protected] SSH login user @ host/server IP address for session connection
