Yum server construction and Configuration

The basic workflow of yum server construction and configuration of YUM is as follows: SERVER: stores all RPM software packages on the server, and analyzes the dependency between each RPM file with relevant functions, record the data into files stored in a specific directory on the server. Client: If you need to install a software, download the dependency file recorded on the server (via WWW or FTP) and analyze the record data downloaded from the server, then obtain all the relevant software and download it all at a time for installation. My environment: CentOS release 5.5 (Final) 1. Install yum package my system is installed by default. If not, find the corresponding installation file.

Let's first look at the file:/etc/yum. repos. d/*. repo. The file name can be defined at will, but the extension must be repo. [root @ localhost yum. repos. d] # cat CentOS-Base.repo [base] name = CentOS-$ releasever-Base # Release List = http://mirrorlist.centos.org /?

FTP, HTTP, and FILE are configured here. Enabled: whether to enable this repository. 1 is for use, 0 is for disable gpgcheck: whether to check the GPG signature (verify whether the package to be installed is officially REDHAT ).
