Centos 下更新yum源
最近公司安全策略升级,默认只能通过https,即tcp/443端口访问外网。造成服务器上yum执行命令时,不断超时,总结一下解决方案:
cd /etc/yum.repos.d/ rm ./* rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo #继续在/etc/yum.repos.d/文件夹下操作 vim CentOS-Base.repo :%s/http/https/g #所有的yum都改为https访问 yum clean all yum makecache
至此,80端口不能访问外网导致yum超时的问题解决。
