Redhat6 使用 yum源

由于Redhat的yum在线更新是收费的，如果没有注册的话是不能使用的，即不能在线安装软件。在这里和大家分享一下如何使用Redhat6 系统用yum源来在线安装软件。 1、删除redhat原有的yum源

# rpm -aq | grep yum|xargs rpm -e --nodeps

2、下载新的yum安装包

　　这里我们使用CentOS的yum源

# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm
# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-3.2.29-30.el6.centos.noarch.rpm

# wget http://mirror.centos.org/centos/6.5/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm 3、安装yum软件包

# rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm
# rpm -ivh  yum-metadata-parser-1.1.2-16.el6.i686.rpm
# rpm -ivh  yum-3.2.29-30.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

注意：最后两个安装包要放在一起同时安装，否则会提示相互依赖，安装失败。 4、更改yum源  #我们使用网易的CentOS镜像源

# cd /etc/yum.repos.d/
# wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo
# vi CentOS6-Base-163.repo

　　编辑文件，把文件里面的$releasever全部替换为版本号，即6 最后保存！或者直接把下面的内存拷贝到CentOS6-Base-163.repo文件中即可（已经修改好）

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

5、清理yum缓存

# yum clean all
# yum makecache     #将服务器上的软件包信息缓存到本地,以提高搜索安装软件的速度
# yum install vim*    #测试域名是否可用

至此，Redhat6可以使用CentOS的yum源在线安装软件了！

6.使用 # yum update

或 # yum upgrade 升级系统

注：两个命令区别：

# yum  update 

升级所有包，改变软件设置和系统设置,系统版本内核都升级
# yum -y upgrade
升级所有包，不改变软件设置和系统设置，系统版本升级，内核不改变
