I have 2 MySql with a master/slave configuration and the replication is failing. The MySql Master crashed and a new register in the mysql-bin.index was created. I deleted this new register because this file was not existed in the file system. Then the MySql Master restarted successfully.
Now, I have the next error in the slave:

I have checked in the MySql Master that the mysql-bin.001050 exist and is not empty.
This is a production environment then new data are inserted every minute. The position value can to change in minutes or seconds. I don't know if this is a problem.
The max_allowed_packet variable has the same value in the two MySql (16M).
Why can not the slave find the binary log file?
You can try this:
Slave: stop slave;
Master: flush logs
Master: show master status; — take note of the master log file and master log position
Slave: CHANGE MASTER TO MASTER_LOG_FILE='log-bin.00000X', MASTER_LOG_POS=106;
Slave: start slave;
I've just created a mysql 5.6 master/slave relationship automatically through my provider's API, meaning I didn't have a root user. So after the slave was setup, I enabled the root user on the slave, which of course broke replication. I need to skip that GTID, but I'm having difficulty understanding the howtos.
STOP SLAVE;
SET GTID_NEXT="5b182ac6-8a79-11e4-8f28-001851cf5e10:10";
BEGIN; COMMIT;
SET GTID_NEXT="AUTOMATIC";
START SLAVE
results in the same error. What's the right GTID to select?

08bc8aa0-8a7a-11e4-8f2d-001851502460 is probably your slave, your master is
Master_UUID: 5b182ac6-8a79-11e4-8f28-001851cf5e10
as you can see some lines above. From the master you have therefore executed transactions 9 - 69. So the next GTID is 70.
Also note, that you should set Auto_Position: 1 with a CHANGE MASTER TO statement. Read more about it here.
We have set up master-slave configuration and I need to know at what time slave is getting updated OR how often slave is getting updated. Where can I see the settings saved for replication.

I have setup Master to Master Replication on MySQL server 5.2 with my existing database. I am sucessfully able to replicate data of my Master 1 to Master 2 with the user named as replication. But I am getting error from Master 1 when I try to connect to master 2. Here is the detail information of them:

Please help me. Your solution will guide me to resolve task. Thank you in advance.
Make sure you can connect from the host of Master 1 DB to Master 2's MySQL socket, you can verify if you are able to connect via shell command:
telnet master-2-ip MYSQLPORT //3306 is the default port for mysql
if this command succeeds (which means you don't get 'Connection Refused'), try connecting with:
mysql -u user -p'password' -H host -P port
if the problem is not connectivity issues posting your mysql logs under /var/log might help a bit more.
Here are the steps i did.
I was Replicating the mysql 5.0.95 as master and 5.5 as a slave. I'm using linux OS. My DB engine is InnoDBenter code here
I have set the master with
/etc/my.cnf
**#mysql Server setup**
server-id=1
bind-address = 192.168.1.41
innodb_flush_log_at_trx_commit=1
sync_binlog=1
log-bin = /var/log/mysql/mysql-bin.log
binlog-do-db=my_db
I have set the slave with
/etc/my.cnf
**#mysql replication client setup**
server-id=5
master-host=192.168.1.41
master-user=web_master
master-password=webmaster
master-connect-retry=60
replicate-do-db=dev_my_db
log-slave-updates
I have granted permission on master as
GRANT SUPER,REPLICATION CLIENT,REPLICATION SLAVE,RELOAD ON *.* TO 'web_master'#'192.168.1.41' identified by 'webmaster';
I have set change master and bin position on the slave
CHANGE MASTER TO MASTER_HOST='192.168.1.41', MASTER_USER='web_master', MASTER_PASSWORD='webmaster', MASTER_LOG_FILE='mysql-bin.00002', MASTER_LOG_POS=107;
I did 2 insert and a update and log my queries
and checked My Master status as
mysql> SHOW master STATUS\G
File: mysql-bin.000004
Position: 13790
Binlog_Do_DB: my_db
Binlog_Ignore_DB:
1 row in set (0.00 sec)
I chcekd my slave and slave status as

I could see the bin log are updated on slave, i couldn't figure out what was causing the issue. As my updates on the master is not replicated on slave.
can any one suggest did i have missed out something?
