gy2006_sw 2023-01-28 阅读 87

[root@localhost ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

--2023-01-28 14:30:34-- https://mirrors.aliyun.com/repo/Centos-7.repo

Resolving mirrors.aliyun.com (mirrors.aliyun.com)... failed: Name or service not known.

wget: unable to resolve host address ‘mirrors.aliyun.com’

解决方法 :
登录root用户,用vim /etc/resolv.conf ,打开rsolv.conf,添加DNS地址

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 223.5.5.5
nameserver 223.6.6.6

若未解决,查看网络配置,使用​ifconfig​ 或 ​ip addr​查看网卡名,用 vim

/etc/sysconfig/network-scripts/ifcfg-(网卡名),查看网络参数是否正常

解决Linux(Loaded plugins: fastestmirror Please use /usr/bin/yum --help)--

yum命令出现Loaded plugins: fastestmirror

vi /etc/yum/pluginconf.d/fastestmirror.conf

把enabled=1改为0

vi /etc/yum.conf

把plugins=1改为0

yum>

sed -i "s/plugins=1/plugins=0" /etc/yum.conf

yum clean all


yum安装时出现错误[Errno 14] curl#6 - “Could not resolve host: ​​mirrors.aliyuncs.com​​; Unknown e解决办法。
