Requesting or Renewing Host certificates

This guide describes how to request a new host certificate or renew an existing one, and what to do with the new/renewed certificate.

If the host already has a valid certificate, skip step 1a) and continue with step 1b)

1a) Request a new host certificate

To request a new host certificate, follow the procedure on the Dutchgrid CA website. Part of this procedure involves downloading and executing a shell script. Executing the script has to be done as user root on server vlaai, in directory /export/perm/share/grid-security/hostname/year (which should probably be created first!). For example, for host graszode in year 2008:

# mkdir -p /export/perm/share/grid-security/graszode/2008
# cd /export/perm/share/grid-security/graszode/2008
# sh ./makerequest.sh .

This will create some files, including one called userkey.pem

Complete the administrative procedure as described on the CA web page and continue with step 2).

1b) Renewing an existing (valid) host certificate

To renew a host certificate, follow the procedure on the Dutchgrid CA website. Part of this procedure involves downloading and executing a shell script. Executing the script has to be done as user root on server vlaai. Create a new directory /export/perm/share/grid-security/hostname/year to hold the new key/certificate pair. Then execute the downloaded script, providing the existing certificate as parameter:

# mkdir -p /export/perm/share/grid-security/tbn01/2008
# cd /export/perm/share/grid-security/tbn01/2008
# ls -l ../2007/usercert.pem
-rw-r--r-- 1 root root 5146 Jan 30  2007 ../2007/usercert.pem
