In my RHEL5, I am using this link to create MySQL replication an did work the first time I did it: http://crazytoon.com/2008/02/29/mysql-how-do-you-set-up-mastermaster-replication-in-mysql-centos-rhel-fedora/
I change the ip address and the hostname and it is not working now. My new ip is 10.100.1.170 and my hostname is wahoo1. The other ip address in my master/master replication is 10.100.1.171 and wahoo2 *This is what wahoo1 my.cnf looks like*: [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock old_passwords=1 auto_increment_increment=2 auto_increment_offset=1 relay-log=wahoo1-relay-bin log-bin=wahoo1-bin binlog-ignore-db=mysql binlog-ignore-db=test server-id = 1 master-host = 10.100.1.171 master-user = slaveuser master-password = slavepw master-port = 3306 [mysql.server] user=mysql basedir=/var/lib [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid *This is what wahoo2 my.cnf looks like:* [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock old_passwords=1 auto_increment_increment=2 auto_increment_offset=2 relay-log=wahoo2-relay-bin log-bin=wahoo2-bin binlog-ignore-db=mysql binlog-ignore-db=test server-id = 2 master-host = 10.100.1.170 master-user = slaveuser master-password = slavepw master-port = 3306 [mysql.server] user=mysql basedir=/var/lib [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid *This is the error I get on my mysqld.log file*: 080401 15:15:07 [Note] Slave SQL thread initialized, starting replication in log 'FIRST' at position 0, relay log './wahoo2-relay-bin.000002' position: 98 080401 15:15:07 [ERROR] Slave I/O thread: error connecting to master ' [EMAIL PROTECTED]:3306': Error: 'Lost connection to MySQL server during query' errno: 2013 retry-time: 60 retries: 86400 HELP!!!!!
