        导入公钥：rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

        导入源：rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm (适用于RHEL-7, SL-7 or CentOS-7)

  [[  for RHEL-6, SL-6 or CentOS-6:   rpm -Uvh http://www.elrepo.org/elrepo-release-6-6.el6.elrepo.noarch.rpm   ]]



   3.My RPM repositories for EL (RHEL, CentOS, ScientificLinux etc) (地址：http://li.nux.ro/repos.html)
