2. 更新 curl
直接使用如下命令进行更新:yum update curl --enablerepo=CityFanforCurl -y


报错:CentOS7升级curl报错:Requires: libnghttp2.so.14()(64bit)

1、更新: yum update nss nss-util nss-sysinit nss-tools

2、安装 epel 源:    yum install epel-release -y

  yum --enablerepo=epel install libnghttp2 -y && yum install libcurl -y

   # 再次执行   yum update curl --enablerepo=CityFanforCurl -y
