See what the installed Yum packages are:

#rpm-aq|grep Yum

To uninstall an installed Yum package:

#rpm-aq|grep Yum | Xargs rpm-e--nodeps

From here, Xargs Ben was found dead.

2. Download the CentOS Yum package

Download the following packages from the 163 image (Http://mirrors.163.com/centos/6/os/x86_64/Packages/) (the version of the download package may be different at different times):

Python-iniparse-0.3.1-2.1.el6.noarch.rpmyum-3.2.29-30.el6.centos.noarch.rpmyum-metadata-parser-1.1.2-16.el6.x86 _64.rpmyum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm Download method: Can download directly from the mirror website, or use wget download:

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-30.el6.centos.noarch.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

3. Install the CentOS package Yum

#rpm-IVH *.rpm

4. Update the Repo file

Enter the configuration directory:

#cd/ETC/YUM.REPOS.D

If there is no Rhel-debuginfo.repo file in the directory, create a new one with the following modifications:

[base]
name=CentOS-$releasever - Base
baseurl=http://mirrors.163.com/centos/6/os/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=http://mirrors.163.com/centos/6/updates/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6

#packages used/produced in the build but not released
#[addons]
#name=CentOS-$releasever - Addons
#baseurl=http://mirrors.163.com/centos/$releasever/addons/$basearch/
#gpgcheck=1
#gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://mirrors.163.com/centos/6/extras/$basearch/
gpgcheck=1
gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/
gpgcheck=1
enabled=0

5. Clear the old cache

#yum Clean All

6. Using the test

List Yum Packages:

#yum List

Installing g++

What is g++? g++ can be used to compile C + + code. Linux installs GCC by default, but often does not install g++.

Find g++ First:

#yum List gcc-c++

The information that is returned contains:

Gcc-c++.x86_64

Therefore, the command to install g++ is:

#yum Install gcc-c++.x86_64

During the installation process, if you are prompted to install certain dependent packages, follow the instructions to install them.

To verify that you have successfully installed g++, check the version:

#g + V
