错误信息
[root@bogon apache-tomcat-7.0.70]# 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>
解决方法
1、查看redhat 7.0系统本身所安装的那些yum软件包
[root@bogon apache-tomcat-7.0.70]# 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
2、卸载这些软件包
[root@bogon apache-tomcat-7.0.70]# rpm -e yum-rhn-plugin-2.0.1-10.el7.noarch --nodeps [root@bogon apache-tomcat-7.0.70]# rpm -e yum-metadata-parser-1.1.4-10.el7.x86_64 --nodeps [root@bogon apache-tomcat-7.0.70]# rpm -e yum-3.4.3-158.el7.noarch --nodeps
3、保证本机电脑能上网
[root@bogon apache-tomcat-7.0.70]# ping www.baidu.com PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data.64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=1 ttl=57 time=5.17 ms64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=2 ttl=57 time=4.52 ms64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=3 ttl=57 time=5.69 ms64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=4 ttl=57 time=3.33 ms64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=5 ttl=57 time=5.57 ms64 bytes from 61.135.169.121 (61.135.169.121): icmp_seq=6 ttl=57 time=5.18 ms
4、找到自己所需要的版本下载
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-2.2.1-1.el7_1.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-3.4.3-158.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-1.1.31-45.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-updateonboot-1.1.31-45.el7.noarch.rpm
wget http://mirrors.163.com/centos/7/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.31-45.el7.noarch.rpm
5、安装软件包
rpm -ivh python-*
rpm -ivh yum-*
6、新建repo 配置文件（如果是其他版本，则将下面的7改为你当前的版本数字）
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. # # [base] name=CentOS-$7 - Base - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=osbaseurl=http://mirrors.163.com/centos/7/os/$basearch/gpgcheck=1gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7#released updates [updates] name=CentOS-$7 - Updates - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=updatesbaseurl=http://mirrors.163.com/centos/7/updates/$basearch/gpgcheck=1gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7#additional packages that may be useful [extras] name=CentOS-$7 - Extras - 163.com #mirrorlist=http://mirrorlist.centos.org/?release=$7&arch=$basearch&repo=extrasbaseurl=http://mirrors.163.com/centos/7/extras/$basearch/gpgcheck=1gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7#additional packages that extend functionality of existing packages [centosplus] name=CentOS-$7 - Plus - 163.com baseurl=http://mirrors.163.com/centos/7/centosplus/$basearch/gpgcheck=1enabled=0gpgkey=http://mirrors.163.com/centos/RPM-GPG-KEY-CentOS-7
7、清除缓存
yum clean all
8、测试是否正常
yum -y install lftp
