RHEL6: Build a YUM source server based on vsFTPD

1. why is it necessary to build a local YUM source to upgrade and install software online using the YUM client tool on a Linux host due to network connection speed and network bandwidth restrictions, installation is often unnecessary for users. However, if a local YUM source server is built in the LAN, the software installation speed is slow. 2. How to build a local YUM Source

1. Why should I build a local YUM source?

When you use the YUM client tool on a Linux host to upgrade and install software online, the installation may be unnecessary because of network connection speed and bandwidth restrictions. However, if a local YUM source server is built in the LAN, the software installation speed is slow.

2. How to build a local YUM Source

Idea: You can obtain the required rpm package from the rhel6 installation disc and use the HTTP or FTP protocol to build a YUM source server on the local LAN.

Steps

(1) install the createrepo Tool

Createrepoa is mainly used to collect the header information of rpm package files in the directory to create repodata software repository data (xml files compressed by gzip ).

Mount/dev/cdrom/media/cdrom // mount the disc

Rpm-ivh/media/cdrom/Packages/createrepo-0.9.8-4.el6.noarch.rpm

(2) install the FTP server

Rpm-ivh/media/cdrom/Packages/vsftpd

(3) configure the software warehouse directory

Refer to the Server directory of the installation CD

Mkdir/var/ftp/pub/Packages

Mkdir/var/ftp/pub/repodata

Copy all RPM Packages from the CD to the/var/ftp/pub/Packages directory (Ensure that the hard disk has sufficient disk space)

Cp-rv/media/cdrom/Packages/*/var/ftp/pub/Packages/

(3) create a software Warehouse Information File

Cd/var/ftp/pub/

Createrepo -- database ./

[Root @ server pub] # ls repodata/

Filelists.sqlite.bz2 other.sqlite.bz2 primary.sqlite.bz2 repomd. xml

Filelists.xml.gz other.xml.gz primary.xml.gz

The corresponding software warehouse information file has been created.

(4) Start the vsftpd service

Service vsftpd start

Chkconfig -- level 35 vsftpd on

(5) Test on another client. First, create a repo file to specify the YUM source location.

Vi/etc/yum. repos. d/server1.repo. Note that the file extension must end with a repo. The file content is as follows:

[Rhel6] // name of the software Repository

Name = rhel6 // description of the software Repository

Baseurl = ftp: // 192.168.100.1/pub // location of the software Repository

Enabled = 1 // whether to use the software Repository

Gpgcheck = 1 // check the GPG signature (used to verify whether the package to be installed is officially RedHat)

Gpgkey = file: // etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release GPG signature KEY location
