记录一下某CentOS6.9镜像的玄学问题
如题 一使用yum就翻车
初步判断是镜像问题
下面就直接搬运了：
1. 查看centos7.2系统本身所安装的yum依赖包
[root@zf-test-web01-4 ~]# rpm -qa|grep yum
yum-plugin-fastestmirror-1.1.31-34.el7.noarch
yum-metadata-parser-1.1.4-10.el7.x86_64
yum-3.4.3-132.el7.centos.0.1.noarch
2. 卸载这些软件包
[root@zf-test-web01-4 ~]# rpm -e yum-plugin-fastestmirror-1.1.31-34.el7.noarch --nodeps warning: /etc/yum/pluginconf.d/fastestmirror.conf saved as /etc/yum/pluginconf.d/fastestmirror.conf.rpmsave [root@zf-test-web01-4 ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps [root@zf-test-web01-4 ~]# rpm -e yum-3.4.3-132.el7.centos.0.1.noarch --nodeps [root@zf-test-web01-4 ~]#
3. 进入centos镜像网站找到自己对应系统需要的yum包
查看系统的命令：
[root@zf-test-web01-4 ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
查看系统的位数：
[root@zf-test-web01-4 ~]# file /bin/ls /bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=aa7ff68f13de25936a098016243ce57c3c982e06, stripped
4.下载yum依赖包
wget http://vault.centos.org/7.2.1511/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm wget http://vault.centos.org/7.2.1511/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget http://vault.centos.org/7.2.1511/os/x86_64/Packages/yum-3.4.3-132.el7.centos.0.1.noarch.rpm
5. 安装yum依赖包
[root@zf-test-web01-4 ~]# rpm -ivh yum-* Preparing... ################################# [100%] Updating / installing... 1:yum-metadata-parser-1.1.4-10.el7 ################################# [ 33%] 2:yum-plugin-fastestmirror-1.1.31-3################################# [ 67%] 3:yum-3.4.3-132.el7.centos.0.1 ################################# [100%]
更换yum镜像源可参考之前写过的一篇文章
