Thanks all! The problem is finally solved!
I add below lines in /etc/fstab, then it's OK!
UUID=47612fc6-286d-4c3f-b5c1-32abf7b3c9f3 /home ext3 defaults 1 2
UUID=07cfacc5-564d-4113-af74-eec8576bfe12 /usr/local ext3 defaults 1 2
UUID=1cfbb0d5-4192-468a-b6ae-f3a4603dedc8 /tmp ext3 defaults 1 2
then UUID here is got from 'blkid', not /dev/disk/by-uuid/, as following:
# blkid
/dev/sda2: UUID="61b8990c-043e-4d1f-9a37-7f330cc49eb5" TYPE="crypt_LUKS"
