I am working thru the http://www.howtoforge.com/installin...tabase-cluster-on-debian-6.0-with-ispconfig-3 manual installing two server mirror. step two Debian 6.08 MySQL Your MySQL connection id is 41 Server version: 5.1.72-2-log (Debian) mysql> SHOW SLAVE STATUS \G; *************************** 1. row *************************** Slave_IO_State: Connecting to master Master_Host: 10.3.192.21 Master_User: slaveuser Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000046 Read_Master_Log_Pos: 106 Relay_Log_File: mysqld-relay-bin.000001 Relay_Log_Pos: 4 Relay_Master_Log_File: mysql-bin.000046 Slave_IO_Running: No Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 106 Relay_Log_Space: 262 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: NULL Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 2013 Last_IO_Error: error connecting to master '[email protected]:3306' - retry-time: 60 retries: 86400 Last_SQL_Errno: 0 Last_SQL_Error: 1 row in set (0.00 sec)
Th master is not able to connect to the slave. Did you create the user "slaveuser" on the slave server already? is here a firewall between the servers that might block mysql traffic?
I stopped at the step that indicates that It is important that both Slave_IO_Running and Slave_SQL_Running have the value Yes in the output. the synchronization step just before this appeared to run successfully (does that mean we have communication?)
restart mysql on the slave. Does it work then when you execute this command on the first server (enter the password of the slaveuser when the mysql command asks for it): mysql -u slaveuser -h 10.3.192.21 -p
mysql> show master status \G; ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation ERROR: No query specified mysql> SHOW SLAVE STATUS; ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation MySQL>
Thats ok, the important part is that the login works. You tested this command on server 1 to connect to server 2 and not on server2? The slave user is limited to replication, so you cant use it to show the status.
Ok so we have confirmed that we can connect and login, and yes I ran the command on server 1 to connect to server 2 (not directly on server 2)so your comment about not being able to show status is correct. what is our next step?
I tried it both by ip and by name to eliminate potential name resolution issue SHOW GRANTS FOR 'slaveuser'@'10.3.192.21'; ERROR 1141 (42000): There is no such grant defined for user 'slaveuser' on host '10.3.192.21' mysql> SHOW GRANTS FOR 'slaveuser'@'WebServer2.dmgenterprises.info'; ERROR 1141 (42000): There is no such grant defined for user 'slaveuser' on host 'webserver2.dmgenterprises.info'
after executing the grant command on both servers, and restarting MySQL I am still getting the same error msg I tried it both by ip and by name to eliminate potential name resolution issue SHOW GRANTS FOR 'slaveuser'@'10.3.192.21'; ERROR 1141 (42000): There is no such grant defined for user 'slaveuser' on host '10.3.192.21' mysql> SHOW GRANTS FOR 'slaveuser'@'WebServer2.dmgenterprises.info'; ERROR 1141 (42000): There is no such grant defined for user 'slaveuser' on host 'webserver2.dmgenterprises.info'
You have tp make a SHOW GRANTS FOR 'slaveuser'@'%' if you want to see the grants set as you didn't set them for the ip address, but for "all hosts".

Just to be sure: You said you used the mysql -h command to connect to server 2 from server 1 - but to test the replication user access you have to connect from slave to master. Did you do it the wrong way or was the information in the quoted post just a mistake? Or is your master server 2 and slave server 1 (quite irritating )?
