错误信息
[root@micocube ~]# yum install gcc-c++ Loaded plugins: product-id, search-disabled-repos, subscription-manager This system is not registered with an entitlement server. You can use subscription-manager to register. There are no enabled repos. Run "yum repolist all" to see the repos you have. To enable Red Hat Subscription Management repositories: subscription-manager repos --enable <repo> To enable custom repositories: yum-config-manager --enable <repo>
查看redhat 7.0系统本身所安装的那些yum软件包
[root@micocube ~]# rpm -qa | grep yum yum-rhn-plugin-2.0.1-10.el7.noarch yum-metadata-parser-1.1.4-10.el7.x86_64 yum-3.4.3-158.el7.noarch
卸载这些软件包
[root@micocube ~]# rpm -e yum-rhn-plugin-2.0.1-10.el7.noarch --nodeps [root@micocube ~]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps [root@micocube ~]# rpm -e yum-3.4.3-158.el7.noarch --nodeps
下载centos的yum 相关 rpm包,包下载地址，版本请从包下载地址获取最新的，可以用wget下载
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-kitchen-1.1.1-5.el7.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/python-chardet-2.2.1-3.el7.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-167.el7.centos.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-metadata-parser-1.1.4-10.el7.x86_64.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-utils-1.1.31-53.el7.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-53.el7.noarch.rpm wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-53.el7.noarch.rpm
安装软件包
rpm -ivh python-* rpm -ivh yum-*
切换到/etc/yum.repos.d/目录
从这里下载repo文件到/etc/yum.repos.d/目录。比如
wget http://mirrors.aliyun.com/repo/Centos-7.repo
清除缓存
yum clean all
可以用yum search vim测试
订阅插件提示：This system is not registered with an entitlement server. You can use subscription-manager to register.
这个Red Hat Subscription Manager订阅管理器，它会让你一直register，解决办法:禁用就好
-
脚本文件: /usr/lib/yum-plugins/subscription-manager.py
-
配置文件: /etc/yum/pluginconf.d/subscription-manager.conf
-
调用了脚本 /usr/share/rhsm/repolib.py
-
去重写或者更新/etc/yum.repos.d/redhat.repo文件。
每次yum调用(不禁掉plugins的情况下)，都会更新此文件。
因此，为了不冲突，可以如下操作:停止掉该插件的使用，在配置文件中把enable=0即可。
[root@micocube ~] vim /etc/yum/pluginconf.d/subscription-manager.conf [main] enabled=0 #将它禁用掉
当进行运行安装命令时可能会报错
[root@localhost yum.repos.d]# yum install glibc.i686 已加载插件：fastestmirror, product-id, search-disabled-repos Determining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com http://mirrors.aliyun.com/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found 正在尝试其它镜像。 To address this issue please refer to the below wiki article https://wiki.centos.org/yum-errors If above article doesn't help to resolve this issue please use https://bugs.centos.org/. http://mirrors.aliyuncs.com/centos/%24releasever/os/x86_64/repodata/repomd.xml: [Errno 14] curl#7 - "Failed connect to mirrors.aliyuncs.com:80; 拒绝连接"
这是因为下载的阿里云的yum源文件里Centos-7.repo文件中$releasever这个变量在Centos-7.repo文件中没有被识别出来。
可以去aliyun的镜像官网上查看下正确地址：https://mirrors.aliyun.com/centos/7/os/x86_64/repodata/repomd.xml
解决办法：将$releasever换成7
[root@localhost yum.repos.d]# sed -i 's/$releasever/7/g' Centos-7.repo
再次清除缓存
yum clean all
再次可以用yum search vim测试
