Persistent "Connecting to master" problem

[Nick Hill]

I'm trying to set up replication from a master server1 to a slave, server2.

So far I've:

1 - set up a "replication" user on server1, giving it Replication Slave permissions only.

2 - set up port forwarding on the router that server1 is connected to, forwarding traffic on port 3306 to server1.

3 - set serverIDs on both servers to unique values

4 - executed FLUSH TABLES WITH READ LOCK; on server1, and then got the current binary log filename & pos with SHOW MASTER STATUS;

5 - mysqldumped the contents of server1 to server2

6 - UNLOCK TABLES; on server1

7 - on server2, executed CHANGE MASTER TO MASTER_HOST='server1.domain.com', MASTER_USER='replication_user_name', MASTER_PASSWORD='replication_password', MASTER_LOG_FILE='recorded_log_file_name', MASTER_LOG_POS=recorded_log_position;

... substituting the relevant values from step 4.


However.... running SHOW SLAVE STATUS; on the slave I get, under Last_IO_Error:

error connecting to master '[e-mail]:3306' - retry-time: 60 retries: 86400

Slave_IO_Running says "no". What have I missed?
