### Now generating a PGP key pair to be used for signing modules.
###
### If this takes a long time, you might wish to run rngd in the background to
### keep the supply of entropy topped up.  It needs to be run as root, and
### should use a hardware random number generator if one is available, eg:
###
###     rngd -r /dev/hwrandom
###
### If one isn't available, the pseudo-random number generator can be used:
###
###     rngd -r /dev/urandom
###
+ gpg --homedir . --batch --gen-key /root/rpmbuild/SOURCES/genkey
gpg: WARNING: unsafe permissions on homedir `.'
gpg: keyring `./secring.gpg' created
gpg: keyring `./pubring.gpg' created　　新开一个终端执行

rngd -r /dev/hwrandom 或者rngd -r /dev/urandom　　rpmbuild完成
