Setting up Master - Slave replication: error connecting to master (Error_code: 2003)
So, I actually had several issues that may come in handy to walk through for others:
Error: 2003
I removed the bind-address from the master
Errno: 1045
Access denied for user
I explicitly set the IP address for the slave user:
GRANT REPLICATION SLAVE ON *.* TO 'slave_user'@'000.000.000.00' IDENTIFIED BY 'password';
instead of
GRANT REPLICATION SLAVE ON *.* TO 'slave_user'@'%' IDENTIFIED BY 'password';
Error 1236
Got fatal error 1236 from master when reading data from binary log: 'log event entry exceeded max_allowed_packet
It turns out the default max_allowed_packet is 1MB for &lt;= 5.6.5 and 4MB for &gt;= 5.6.6.
I set both of these manually to 16MB as per this article
Error 1236
Got fatal error 1236 from master when reading data from binary log: 'bogus data in log event
I followed the instructions in this answer
That solved the last of my errors and the replication appears to be working as expected now!
