certificate renew in SGE 5.3

a question on certificate renew in SGE 5.3
After some investigation, the followings are some observations

  • one can use inst_sge -m -csp to install the master server that will use the openssl certificate
  • By default the certificate is valid for 365 days
  • The sge installation did not document how you renew the certificate after one year
  • after examine the inst_sge script, one can use the following methods
    1. make sure SGE_ROOT and SGE_CELL is set
    2. cd $SGE_ROOT/$SGE_CELL/common/sgeCA/certs
    3. $SGE_ROOT/util/sge_ca -extend cert.pem -days 730 -outdir ./
    4. it will generate extended_cert.pem in the current directory
    5. shutdown the master $SGE_ROOT/SGE_CELL/common/rcsge stop
    6. cp extended_cert.pem cert.pem
    7. restart master SGE_ROOT/$SGE_CELL/common/rcsge start
