1 安装libnghttp2.so.14依赖

如升级时提示Requires: libnghttp2.so.14()(64bit)错误

yum install epel-release -y

2 安装curl的repo

wget http://mirror.city-fan.org/ftp/contrib/yum-repo/rhel7/x86_64/city-fan.org-release-2-2.rhel7.noarch.rpm
rpm -ivh city-fan.org-release-2-2.rhel7.noarch.rpm

3 修改[city-fan.org]的enable为1

vim /etc/yum.repos.d/city-fan.org.repo

[city-fan.org]
name=city-fan.org repository for Red Hat Enterprise Linux (and clones) $releasever ($basearch)
#baseurl=http://mirror.city-fan.org/ftp/contrib/yum-repo/rhel$releasever/$basearch

enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-city-fan.org
