  # reposync -n --repoid=EPEL -p / --download-metadata

• Update repository metadata

  # createrepo /EPEL/ -g 66b8680793d983f01395176215ae7c5291578797ed3e327dfb65e9880d0de49e-comps-Everything.x86_64.xml

  ServerAdmin root@server.deepsoft.com
  ServerName mirror.nobody.com.tw
  DocumentRoot "/var/www/html/Repo"
