centos7.2执行yum-yinstall报错Metadatafiledoesnotmatchchecksum
分析结论
1,Metadata file does not match checksum报错在于元文件的校验值与元文件不匹配
2,元数据是指 mnt/repodata/436345f4b666f0a461d479ccfabc2c22823d4f2173c2653e5250fea62f0afe98-c7-x86_64-comps.xml.gz 这种文件
其所在路径为 光盘/repodata
3,yum的配置文件分为主配置文件和 各自独立的配置文件
4,yum主配置文件在/etc/yum.conf
5, yum各自独立的配置文件在/etc/yum.repos.d/不同的子目录
6,续上,这个不同的子目录对应于自定义的yum配置源配置文件
7,yum的本地cache缓存可见yum主配置文件/etc/yum.conf获取
8,关于元文件的校验值与元文件的配置信息在 repomd.xml获取,其具体内容如下:
42a80e759522768b2cc357553bb64bd7345b06abeb60187f881089b859a63454 --sha256校验算法
3464f99938d4614cd1c9048a8e78a8016b5fc0732d2aed9108f45a1e58cf3e80
--sha256校验算法对应的元数据或元文件

3,从报错可知是加载光盘中的如下很长的文件校验好像与什么不匹配
[root@card2 yum.repos.d]# ls -l /mnt/repodata/436345f4b666f0a461d479ccfabc2c22823d4f2173c2653e5250fea62f0afe98-c7-x86_64-comps.xml.gz

[root@card2 yum.repos.d]#
上述长文件打不开
[root@card2 yum.repos.d]# strings /mnt/repodata/436345f4b666f0a461d479ccfabc2c22823d4f2173c2653e5250fea62f0afe98-c7-x86_64-comps.xml.gz
[root@card2 yum.repos.d]# ^C
4,会不会上述加载光盘中的长文件与光盘对应目录的配置文件repomd.xml有什么关系呢
[root@card2 repodata]# pwd

3,从报错可知是加载光盘中的如下很长的文件校验好像与什么不匹配
[root@card2 yum.repos.d]# ls -l /mnt/repodata/436345f4b666f0a461d479ccfabc2c22823d4f2173c2653e5250fea62f0afe98-c7-x86_64-comps.xml.gz

上述长文件打不开
[root@card2 yum.repos.d]# strings /mnt/repodata/436345f4b666f0a461d479ccfabc2c22823d4f2173c2653e5250fea62f0afe98-c7-x86_64-comps.xml.gz
