Software Management of Linux

When it comes to software management everyone is not unfamiliar, most of Windows directly download. exe files directly installed, download from the Control Panel uninstall, then we discuss how to install and uninstall common software under the Linux system.

Package Management Overview

RPM Package management methods and the advantages of compiling and installing:
1. Easy to update installed packages;
2. Easy to protect configuration files; (not covered)
3. Easy to track installed files

RHEL6 Package Management method?
Rpm
Yum can resolve dependencies

If a, b two packets are found to be mutually dependent can be installed together (RPM-IVH a B)

-------------------------RPM Management-----------------------------------
Name httpd-2.2.15-26.el6.x86_64.rpm

Software Name: httpd
Package Name: httpd-2.2.15-26.el6.x86_64.rpm
2.2.15-26: Major version, minor version number, revision number-release number. Support system version. 64bit. Suffix name

See which packages the system has installed
Rpm-qa
Q Query
A All

To see if the specified package is installed
Rpm-qa | grep httpd

Installation
RPM-IVH httpd-2.2.15-26.el6.x86_64.rpm

-I--install installation
-V--verbose Display the installation process
-H--hash has a progress bar

Unloading:
RPM-E--erase Software Name

See where the software is installed
RPM-QL vsftpd

View the software configuration file
RPM-QC vsftpd

Find out who the software is with the configuration file
Rpm-qf/etc/vsftpd/vsftpd.conf

View detailed information about installed software
Rpm-qi vsftpd

View details of the software that is not installed
Rpm-qi vsftpd-2.2.2-11.el6.x86_64.rpm

See what files can be extracted from the software that is not installed
RPM-QLP vsftpd-2.2.2-11.el6.x86_64.rpm

If the configuration file is corrupted
1. See which software is installed---The package name of this file
2. Delete this profile after backup
3. Reinstall--force (mandatory installation)

Help document for querying software
RPM-QD vsftpd

Check signature
Rpm-k,--checksig package name

Rpm-k vsftpd-2.2.2-11.el6.x86_64.rpm

Import Signature
RPM--import Import Key

RPM--import/etc/pki/rpm-gpg/rpm-gpg-key-redhat-release

Software package Experience (S M U T ... ) Modify the configuration file and view
Rpm-v vsftpd

Upgrade software
-U,--upgrade=<packagefile>+

RPM-UVH vsftpdxxx.rpm


--force If the package is already installed and you want to reinstall it (recommended only for installation)
RPM-IVH vsftpd-2.2.2-11.el6.x86_64.rpm--force

--nodeps does not check package dependencies (only used when uninstalling)
RPM-E httpd--nodeps

---------------------------------Binary Package------------------------
. bin. Sh. Bundle---> into its directory./xxx.sh


---------------------------Source Code-----------------------------------
1.tar XVFJ httpd-2.2.25.tar.bz2
2.CD httpd-2.2.25
3./configure--prefix=/usr/local/apache Specify installation path Check installation environment
4.make Generate Makefile file for compilation
5.make Install compilation Installation
6./usr/local/apache/bin/apachectl Start Open Service
7.cd/usr/local/apache/bin
8.CP apachectl/bin/guaranteed to open the program directly in any directory

Make clean clears the files that have been compiled

Yum Install *gcc*
------------
Yum Management

Can resolve dependencies

Configure Yum

Yum configuration file
Vim/etc/yum.repos.d/rhel-source.repo

Create a yum configuration file yourself, requiring this profile suffix to be repo

Yum Categories
1. Local Yum (file)
2. Remote Yum (FTP http)


/etc/yum.repos.d/rhel-source.repo

[RHEL6] Label
Description of name=red Hat Enterprise Linux multi-Yum warehouse function
Baseurl=file:///mnt/server specifying the location of the Yum Warehouse
enabled=1 enabling local Yum 0 means that local yum is not enabled
Gpgcheck=1 enabling RPM signature 0 does not enable RPM signing
Gpgkey=file:///etc/pki/rpm-gpg/rpm-gpg-key-redhat-beta,file:///etc/pki/rpm-gpg/rpm-gpg-key-redhat-release Location of key


Yum Clean all check syntax cleanup cache

Yum repolist check syntax and see how many packages are available

Installation
Yum Install Vsftpd-y

Yum Clean all cache if the Yum configuration file has changed, you need to execute this command
Repolist See if Yum is in effect
Erase/remove vstpd Uninstall

GroupInfo "Virtualization" view the members of a software group's information group

Create a yum warehouse manually
1.yum Install Createrepo

2.mkdir/yumtest/Creating a Warehouse

3.CP httpd* vsftpd*/yumtest/

4.createrepo/yumtest/

5.touch/etc/yum.repos.d/test.repo
