Yum Software Warehousing Services

What?

Yum is a way to install software on a Linux system.

Why

Yum installs software that automatically considers the dependencies of the package, does not require a manual installation of the required dependencies, is more convenient to use than RPM, and also enables a large number of software installation deployments, so we learn how to deploy and use the Yum repositories.

where

The Yum Software warehouse is divided into three ways

• Local services, file:///
  

• http service, / http
  

• FTP Service, ftp://

How?

The Yum server is used to provide packages ( rpm package), as well as the need to provide warehouse data ( Repodata ), which collects all rpm the packet header information.

RHEL6.5 and above installation CD has already provided the warehouse data, so it is only possible to copy the contents of the disc to the specified directory.

• Local Service

1, mount the disc image to/media

2. Delete the existing Yum configuration file

3, create a new Yum profile//name customization, but end with. Repo

4, test with Yum Update command

5, install software using yum-y install software name

• FTP Service

One, the configuration of the Yum warehouse side

1. Install VSFTPD on the Yum Warehouse server

650) this.width=650; "src=" http://s1.51cto.com/wyfs02/M01/82/DF/wKioL1djkW-SuNXJAAEcd4PH8vg256.jpg "title=" 6.jpg " alt= "Wkiol1djkw-sunxjaaecd4ph8vg256.jpg"/>

2, create a directory in/var/ftp/to store the warehouse source

3. Use the Createrepo tool to generate warehouse data files

Use command: Createrepo--database /var/ftp/other (software storage location)

Since rhel6.5 already contains data files, it is not necessary to create a separate

4, add Firewall rule

Second, the Yum client operation

1, install the FTP tool on the Yum client

650) this.width=650; "src=" http://s4.51cto.com/wyfs02/M01/82/E0/wKioL1djl37R-sebAAD30acXTcs191.jpg "title=" 9.jpg " alt= "Wkiol1djl37r-sebaad30acxtcs191.jpg"/>

Attention! FTP connection server will error, as follows

This issue is caused by the server's firewall blocking the FTP passive connection

Passive connection: PASV connection means that the client through the FTP port number and FTP server to establish a link, when the need to transfer data, the server will be on the link through the PASV command to open a port, tell the client can connect through this port, transfer files, Firewall settings are one more step.

Workaround: Modify the VSFTPD configuration file and set up the firewall

2. Delete the previous RPM file and create a new
