following errors 101021 19:12:23 [ERROR] Slave I/O: error connecting to master 'root@xxx.xxx.xxx.xxx:3306' - retry-time: 60 retries: 86400, Error_code: 1045

Sever 1 has mysql 5.0.77 and server 2 has mysql version 5.1.41

回答1:

Error_code: 1045 means that there is a problem with your credentials.

Try to connect with your replication user credentials like :

mysql -h host -u your_user -p your_password

Note that the password is limited to 32 characters.
