# 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.

有时候因为系统时间不对会报curl错误,ntp又搜不到
rpm -ivh http://mirrors.wlnmp.com/centos/wlnmp-release-centos.noarch.rpm
yum -y install wntp
ntpdate ntp1.aliyun.com
如果报ssl错误
vi /etc/yum.conf
# 添加
sslverify=false
硬件时间同步系统时间
