1、update yumnode

1、先查看redhat7.2中yum的包版本
[root@localhost jiayimeng]#  rpm -qa | grep yum
yum-rhn-plugin-2.0.1-5.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-langpacks-0.4.2-4.el7.noarch
yum-utils-1.1.31-34.el7.noarch
yum-3.4.3-132.el7.noarch
 
2、刪除原有的yum包
[root@localhost jiayimeng]# rpm -e yum-rhn-plugin-2.0.1-5.el7.noarch yum-metadata-parser-1.1.4-10.el7.x86_64 yum-langpacks-0.4.2-4.el7.noarch yum-utils-1.1.31-34.el7.noarch yum-3.4.3-132.el7.noarch --nodeps
警告：/etc/yum/pluginconf.d/langpacks.conf 已另存爲 /etc/yum/pluginconf.d/langpacks.conf.rpmsave
 
3、在各大開源鏡像站下載對應包
163： 
aliyun： 
中科大：
 
4、下載並ftp到redhat server
[root@localhost jiayimeng]# ll
總用量 1472
-rw-r--r--. 1 root root 1288436 12月 22 17:13 yum-3.4.3-154.el7.centos.noarch.rpm
-rw-r--r--. 1 root root   28348 12月 22 17:13 yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
-rw-r--r--. 1 root root   32776 12月 22 17:13 yum-plugin-fastestmirror-1.1.31-42.el7.noarch.rpm
-rw-r--r--. 1 root root   25592 12月 22 17:13 yum-updateonboot-1.1.31-42.el7.noarch.rpm
-rw-r--r--. 1 root root  120184 12月 22 17:13 yum-utils-1.1.31-42.el7.noarch.rpm
 
5、安裝軟件包
[root@localhost jiayimeng]# rpm -ivh yum-*
警告：yum-3.4.3-154.el7.centos.noarch.rpm: 頭V3 RSA/SHA256 Signature, 密鑰 ID f4a80eb5: NOKEY
錯誤：依賴檢測失敗：
    python-urlgrabber >= 3.10-8 被 yum-3.4.3-154.el7.centos.noarch 須要
    rpm >= 0:4.11.3-22 被 yum-3.4.3-154.el7.centos.noarch 須要
     
6、報錯，依賴包的版本不符
解決方案有兩個，一是在網上找低版本rpm包安裝，二是將所依賴的python-urlgrabber和rpm包升級，我這裏用第二個方法
----下載----

7、更新yum源
[root@localhost jiayimeng]# rm /etc/yum.repos.d/redhat.repo 
rm：是否刪除普通文件 "/etc/yum.repos.d/redhat.repo"？y
[root@localhost jiayimeng]# vim /etc/yum.repos.d/CentOS-Base.repo
#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.
#

8、清除yum緩存
[root@localhost ~]# yum clean all
 
9、生成緩存
[root@localhost ~]# yum makecache
