在执行yum命令时,出现以下异常 [root@hisdb1 yum.repos.d]# yum -y install gcc Loaded plugins: fastestmirror, langpacks You have enabled checking of packages via GPGkeys. This is a good thing. However, you do not have any GPG public keysinstalled. You need to download the keys for packages you wish to install andinstall them. You can do that by running the command: rpm--import public.gpg.key Alternatively you can specify the url to the keyyou would like to use for a repository in the 'gpgkey' option in arepository section and yum will install it for you. For more information contact your distributionor package provider.
