Is it possible for two mysql server one is master and second is slave ?

Error 1236 looks like this from SHOW SLAVE STATUS:

Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: ‘Client requested master to start replication from position > file size’

In other words, the replica is requesting data at a certain point in the log (its current position), but the master’s log file doesn’t reach that point (so there are missing entries). Replication stops because because this is a logic error: if a replica is caught up to X, then the master must have been at at least X, but it’s not! One reason why this may happen is if MySQL hasn’t flushed all of the data in the binlog to disk.

When might MySQL do that? When sync_binlog = 0. Read more about that variable in the MySQL docs.

Introduction : 

In MySQL the replication is logical. And the DB changes were written to mysqlbinlog. This mysqlbinlog is pulled (IO Thread) and applied ( SQL Thread) by the slave servers. Binlog is the key for MySQL Replication.

Binary logging format is of three types.

• Statement
• ROW
• Mixed

ROW based replication benefits the smaller writes ( OLTP ) work load. The events are logged based on how individual table rows are affected. Primary key and Unique keys on tables benefits the efficient writes.

Major Drawbacks in Row Based Replication ( RBR ):

MySQL Binlog troubleshooting becomes harder at times when you have ROW/Mixed binlog formats.

ROW format is claimed to be a better Binlog Format for data consistency and scalability. But ROW based replication tends to have a couple of drawbacks when it was …

In this blog, we’ll look at group replication and how it deals with flow control (FC) and replication lag. 

Overview

In the last few months, we had two main actors in the MySQL ecosystem: ProxySQL and Group-Replication (with the evolution to InnoDB Cluster). 

While I have extensively covered the first, my last serious work on Group Replication dates back to some lab version years past.

Given that Oracle decided to declare it GA, and Percona’s decision to provide some level of Group Replication support, I decided it was time for me to take a look at it again.

We’ve seen a lot of coverage already too many Group Replication topics. There are articles about Group Replication and performance, Group Replication and basic functionalities (or lack of it like automatic node provisioning), Group Replication and ProxySQL, and so on.

But one question kept coming up over and over in my …

There are a lot of different reasons behind this error. Sometime, you may not see the exact issue on the error message. You have to dig deeper to identify the exact cause. It may take a lot of time and energy to debug this error.

Upstream platform vendors have announced the general end of life (EOL) for Red Hat Enterprise Linux 5 (RHEL 5) and its derivatives, as well as Ubuntu 12.04 LTS. With this announcement comes some implications to support for Percona software running on these operating systems.

RHEL 5 was EOL as of March 31st, 2017 and Ubuntu 12.04 LTS was end of life as of April 28th, 2017. Pursuant to our end of life policies, we are announcing that these EOLs will go into effect for Percona software on August 1st, 2017. As of this date, we will no longer be producing new packages, binary builds, hotfixes, or bug fixes for Percona software on these platforms.

Clients require strong security measures for PCI, HIPAA or PHI. You must encrypt MySQL “at rest” to satisfy the data managed under these standards. InnoDB’s built-in encryption features work, but there are some caveats to that solution.

In this talk, you’ll see how to encrypt your entire disk to protect everything from data, redo logs and binary logs.
