CentOS6.3 system yum local image Installation

CentOS6.3 system yum local image installation yum. conf file description [Introduction] yum is an installation and deletion program designed for the rpm system for automatic update of software packages. It automatically solves the software package dependency problem, making it easier to install and delete the rpm software. Yum, namely yellowdog updater modified, was developed by the DUKE University's Linux development team. [Configuration file overview] The yum configuration file is divided into two parts: main and repositorymain, which define global configuration options. The entire yum configuration file should have only one main. It is usually located in/etc/yum. conf. The repository section defines the specific configurations of each source/server. There can be one or more configurations. It is usually located in the files in the/etc/yum. repo. d directory. [Introduction to yum. conf] The yum. conf file is generally located in the/etc directory and generally only contains configuration options in the main section. The content is generally [main] cachedir =/var/cache/yum # cachedir: cache directory when the yum software is updated. The default value is/var/cache/yumdebuglevel = 2 # debuglevel: debug information output level, ranging from 0 to 10. The default value is 2 logfile =/var/log/yum. log # logfile: the directory that stores the system update software logs. You can go to the/var/log/yum. log File to query the updates you have made in the past. Pkgpolicy = newest # package policy. There are two options: newest and last. If you set multiple repository and the same software is stored in the same time in different repository, which one should yum install, if it is newest, yum will install the latest version. If it is last, yum will sort the server IDs in alphabetical order and select the software installation on the last server. Generally, select newest. Distroverpkg = redhat-release # specify a software package. yum determines your release version based on the package. The default value is redhat-release, you can also install any rpm packages for your own release. Tolerant = 1 # If the value is 1, yum ignores any packet errors. For example, if you run yum to install baz, if the baz package is already installed in the system, yum will continue to install baz again without reporting an error. The default value is 1. If exactarch = 1 # is set to 1, yum only installs software packages that match the system architecture. For example, yum does not install software packages of i686 in systems suitable for i386. The default value is 1 retries = 20 # Number of retries after an error occurs in the network connection. If it is set to 0, an unlimited number of retries will be made. The default value is 6 obsoletes = 1 # This option is used for cross-version release upgrade. Gpgcheck = 1 # there are two options: 1 and 0, which respectively indicate whether or not to perform gpg verification. This option is valid for each repository if it is set in [main. The default value is 0. # put your repos here or in separate files named file. repo # in/etc/yum. repos. d [yum. variable in conf: $ releasever indicates the version number of the release. If the system is fedora core 6, 6 $ basearch is returned: displays the basic architecture type. If the system is i386 or i686, all files in the/etc/yum. repos. d/directory are returned to the package for backup.
