Redhat6 使用 yum源

转载▼

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

<span style="color:#2F3699;word-wrap: normal; word-break: normal; line-height: 24.545454025268555px; font-size: 16px;"># rpm -aq | grep yum|xargs rpm -e --nodeps</span>

2、下载新的yum安装包

　　这里我们使用CentOS的yum源

</pre><div><span style="color:#2F3699;word-wrap: normal; word-break: normal; line-height: 24.545454025268555px; font-size: 16px;"># <wbr>wget <wbr>http://mirror.centos.org/centos/6.6/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm# <wbr>wget <wbr>http://mirror.centos.org/centos/6.6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm# <wbr>wget <wbr>http://mirror.centos.org/centos/6.6/os/i386/Packages/yum-3.2.29-30.el6.centos.noarch.rpm</wbr></wbr></wbr></wbr></wbr></wbr></span></div><div><span style="color:#2F3699;word-wrap: normal; word-break: normal; line-height: 24.545454025268555px; font-size: 16px;"># <wbr>wget <wbr>http://mirror.centos.org/centos/6.6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm</wbr></wbr></span></div><h3 style="margin: 0px; padding: 0px; border: 0px; list-style: none; font-size: 14px; font-family: 宋体; line-height: 22px; background-color: rgb(255, 255, 255);">3、安装yum软件包</h3><pre name="code" style="white-space: normal; margin: 8px; padding: 3px; width: 600px; background-color: rgb(255, 255, 255); border-width: 1px 1px 1px 5px; border-style: dashed dashed dashed solid; border-color: rgb(187, 187, 187); word-wrap: break-word;"><span style="font-family:Consolas, Monaco, Bitstream Vera Sans Mono, Courier New, Courier, monospace;color:#2F3699;word-wrap: normal; word-break: normal; line-height: 24.545454025268555px; font-size: 16px;"><span style="word-wrap: normal; word-break: normal; line-height: 22px; white-space: pre-wrap;"># 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</span></span>

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

<span style="color:#2F3699;word-wrap: normal; word-break: normal; line-height: 24.545454025268555px; font-size: 16px;"># cd /etc/yum.repos.d/# wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo# vi CentOS6-Base-163.repo</span>

　　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）

########################################################################## CentOS-Base.repo## 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.##[base]name=CentOS-6 - Base - 163.combaseurl=http://mirrors.163.com/centos/6/os/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=osgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#released updates[updates]name=CentOS-6 - Updates - 163.combaseurl=http://mirrors.163.com/centos/6/updates/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updatesgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#additional packages that may be useful[extras]name=CentOS-6 - Extras - 163.combaseurl=http://mirrors.163.com/centos/6/extras/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extrasgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#additional packages that extend functionality of existing packages[centosplus]name=CentOS-6 - Plus - 163.combaseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplusgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#contrib - packages by Centos Users[contrib]name=CentOS-6 - Contrib - 163.combaseurl=http://mirrors.163.com/centos/6/contrib/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contribgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#########################################################################

5、清理yum缓存

<span style="color:#2F3699;word-wrap: normal; word-break: normal; line-height: 24.545454025268555px; font-size: 16px;"># 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</span>

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
