ขึ้นแบบนี้หลังใช้คำสั่งติดตั้ง mysql --> rpm -ivh Percona-Server-* --nodeps --force
Percona Server is distributed with several useful UDF (User Defined Function) from Maatkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"
See
http://code.google.com/p/maatkit/source/browse/trunk/udf for more details
ต้องแก้ไข้ตรงไนครับ
