mysql - How to fix java.sql.SQLException: Server is running in --secure-auth mode, but 'user'@'host' has a password in the old format; (...)? -


after upgrading mysql 5.1 5.6, trying start jboss failed exception:

java.sql.sqlexception:    server running in --secure-auth mode, 'user'@'localhost'    has password in old format;  please change password new format

how fix issue?

first, need locate my.cnf file, should @ following path:

mysql server 5.6\my.cnf

next find line says old_passwords=0 , change old_passwords=1. tell mysql use password hashing algorithm compatible going way version 4.0, covers use case.

now when start server, password problem should go away. if want upgrade passwords latest version, can use set password each user with flag old_passwords=0.

please keep in mind mysql upgraded password algorithm security reasons, should not view setting old_passwords=1 long term solution.

see here more information.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
