Linux Basics (11)--Package management--rhel6.5

1. RPM Package Management

RPM Full name is Redhat Package Manager and can only be used for Redhat series system packages management, such as Rhel, Centos, Fedora

The disc image in this article is mounted under/MNT.

System comes with RPM package stored under./mnt/packages, LS | Wc-l can find out the number of RPM packages the system comes with.

(1) Install RPM package

rpm-ivh/mnt/packages/xxx.rpm

If a relationship has occurred since, you can force the ignore:

rpm-ivh/mnt/packages/xxx.rpm

(2) RPM related parameters

Zsh whether to install

Rpm-q zsh

Whether the software containing multiple RPM packages is installed:

Rpm-qa | grep zsh

Zsh installed into those files:

RPM-QL zsh

Zsh which software is installed for this file:

Zsh which package is installed:

RP-QF ' which zsh '

These files are generated when the query is installed before the software is installed:

rpm-qpl/mnt/packages/zshxxx.rpm

To upgrade a specified package:

rpm-uvh/mnt/packahges/zshxxx.rpm

Uninstalling the Software:

Rpm-e zsh

Force uninstall, even if there is a dependency, there may be a problem:

RPM-E zsh--nodeps

Verify the integrity of the RPM package:

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

2. Yum Software Management

Using RPM to install the software, users need to handle their own dependencies, Yum can solve the problem, that is, Yum will automatically solve the software management process encountered in the dependency problem.

Yum will automatically download the package and install it, yum based on the C/S architecture, this article uses the local Yum source.

(1) Configure local Yum source

To back up the Yum source configuration file:

Cp/etc/yum.repos.d/rhel-source.repo/etc/yum.repod/rhel-source.repo.bak #配置文件在修改前都需要进行备份.

Clear existing information:

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

To write new configuration information:

[Rhel-yum] #yum源名称, this name is unique and is used to differentiate between different yum sources.

Name=rhel-source #对本yum源的描述

Baseurl=file:///mnt #yum源的路径, the directory where the Repodata directory is located, repodata the dependencies between packages

Enabled=1 # 1: Start yum source, 0: Off

Gpgcheck=0 #不进行公钥检查.

(2) Subsequent configuration

Flush yum Cache, update yum source

Yum Clean All

Generate a new list

Yum List

This local Yum source configuration is complete

(3) Verification

Installing ZSH

Yum Install-y zsh

(4) Install a set of packages

Yum Groupinstall "Development tools"-Y

Yum Grouplist

(5) Enquiry

Yum List z*

Yum Search zsh

Query the role of a package:

Rpm-qpi/mnt/packages/zshxxx

(6) Delete

Yum Remove zsh-y

3. SOURCE installation Package

Source installation due to the way the software varies, the source package comes with the main instructions.

(1) General source code installation is to install three axes:

./configure #检查环境

Make #编译, make-j 4 4 thread compilation for faster compilation

Make install #安装 and make install-j 4 4 thread installation.

(2) Uninstall

Make uninstall #此种方法有时会删不干净, so it is recommended to find the installation directory directly to remove the installation directory.

(3) When compiling again

Make clean

./configure--prefix=xxx (Installation path)

Make-j 4

Mkae Install-j 4

4. Comparison of RPM Yum and source installation

Rpm+yum: Convenient, low software version. Good stability, easy to manage. Performance is slightly worse.

SOURCE manual: Trouble, software version new. The stability is slightly poor, the management is slightly poor. Good performance.

5. Install the SRC.RPM package

The src.rpm is because the RPM package can only be installed in the Redhat series, so the src.rpm is provided by the user to install according to their needs.

Rpmbuild--rebuild lrzszXXX.src.rpm

/root/rpmbuild/rpms/x86_64/to generate the corresponding RPM file, the above method can be installed.
