I spoke to soon!!!
Here is the error about 1.5 hours after replication has started.
121205 16:39:51 [ERROR] Slave: Error 'Duplicate entry '3468897' for
key 1' on query. Default database: 'parallax'. Query: 'INSERT INTO watchdog

121205 16:39:51 [ERROR] Error running query, slave SQL thread aborted. Fix
the problem, and restart the slave SQL thread with "SLAVE START". We
stopped at log 'mysql-bin.000289' position 86451409
--------------------------------------------
Sorry for the long message, below are the steps use to create my
replication.
When I created the replication, I followed the steps here :
http://crazytoon.com/2008/01/29/mysql-how-do-you-set-up-masterslave-replication-in-mysql-centos-rhel-fedora/
I am on a red hat server.
-------
I set my firewall to accept info from server1 on server2
SERVER1:
tcp 0 0 wahoo.sdcwa.org:mysql wahooesc.sdcwa.org:52131
ESTABLISHED 30145/mysqld
SERVER2:
tcp 0 0 wahooesc.sdcwa.org:52131 www.sdcwa.org:mysql
ESTABLISHED 30875/mysqld
-------------
I have try using the SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
I have also done these steps where in SERVER1
FLUSH TABLES WITH READ LOCK;
SHOW MASTER STATUS;
+------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000289 | 42394063 | | |
+------------------+----------+--------------+------------------+
Then Dump SERVER1 database then you unlock SERVER1 database
and copy it to SERVER2 then FLUSH TABLES WITH READ LOCK;
I proceed to STOP SLAVE then add the database to SERVER2 then
CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000289',
MASTER_LOG_POS=42394063; to synch with the SERVER1
Then I start SERVER2 and the output of slave status is:
mysql> SHOW SLAVE STATUS\G

1 row in set (0.00 sec)
-----------------------
I get the folllowing on my mysql.err:
121205 15:09:56 [Note] Slave SQL thread initialized, starting replication
in log 'mysql-bin.000289' at position 42394063, relay log
'/var/log/mysql/mysql-relay-bin.000001' position: 4
121205 15:09:56 [Note] Slave I/O thread: connected to master '
sdcwa_slave@192.168.1.21:3306', replication started in log
'mysql-bin.000289' at position 42394063
Everything is GOOD, for a little while and then I get an error on mysql.err:
---------------------
Now if I do the SKIP FLAG many times, I will error after error...
I do not see how replication works so well for others if I am using the
steps in the link
on top of this message.
THANKS!!!
