Linux basic configuration and Management 5 RPM package management

1 Source Code Form

1 The vast majority of open source software is directly published in the form of source code

2 source code is usually packaged into a tar.gz archive zip file

3 The source code of the program needs to be compiled into binary form before it can be run using

4 The basic compilation process of the source code is:

1./configure Check the compilation environment, related library files and configuration parameters and generate Makefiel

2 make compiles the source code to generate the executable file

3 Make install installs the generated executable file to the current computer

5 source code in the form of software is more cumbersome to use, but the compatibility and control of the better

6 open source software usually uses a lot of other open source software function, so open source software will have a lot of dependencies

2 RPM

1 The disadvantages of the source code form: complex operation, long compilation time, more prone to errors

2 Advantages of the form of source code: Applicable to all systems, can be customized

3 to facilitate the development of RPM (Redhat Package Manager), early in order to give "Red hat" use

4 RPM simplifies installation management of open source software by compiling the source code into executable files based on a specific platform operating system and saving dependencies

The 5 RPM design objectives are as follows

Easy to use

Publish (. rpm) using a single package format file

Can be upgraded

Tracking software Dependencies

Basic information Query

Software verification function

Multi-platform Support

Common naming conventions for 6 RPM software packages

Like linuxcast-1.2.0-30.ei6.i686.rpm.

The form is name-version. System. 32/64 bits. rpm

installation command for 7 rpm

Installation software: Rpm-i software.rpm//Generally we are using-IVH as a parameter

Uninstall software: RPM-E software

Upgrade form installation: Rpm-u software-new software.rpm

RPM supports installation of software via HTTP,FTP protocol

RPM-IVH http.../software.rpm

8 We usually add two parameters V and h after I install

V is to display the relevant information, H is to show the progress bar

9 rpm Common Query commands

RPM-QA list all installed RPM software

RPM-QF filename query Specifies which RPM package the file belongs to

Rpm-qi PackageName Query Package information

RPM-QL packagename query Specifies the files that the package contains

RPM-QIP software.rpm Query rpm file information

Rpm-qilp software.rpm query rpm file contains files

RPM Software Verification Command:

1 Verify RPM Files Rpm-k software.rpm

2 Verifying the installed software rpm-v softname
