yum安装提示如下错误:
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again
解决办法:
1、查看证书时间
rpm -qa |grep ca-certificates
如果时间比较早,更新时间
yum --disablerepo=epel -y update ca-certificates
2、yum提示yum no package mod_security available.
yum install epel-release
3、apache启动失败:Name or service not known: mod_unique_id: unable to find IPv4 address of "bango"
vi/etc/hosts
