A database is a structured collection of data. It may be anything from a simple shopping list to a picture gallery or the vast amounts of information in a corporate network. To add, access, and process data stored in a computer database, you need a database management system such as MySQL Server. Since computers are very good at handling large amounts of data, database management systems play a central role in computing, as standalone utilities, or as parts of other applications.

MySQL is a relational database management system (RDBMS) based on SQL (Structured Query Language). First released in January 1998, MySQL is now one component of parent company MySQL AB's product line of database servers and development tools. It is used in a wide range of applications, including data warehousing, e-commerce, Web databases, logging applications, and distributed applications. Now, it becomes the world's most popular open-source database because of its fast performance, high reliability, ease of use, and dramatic cost savings.

How to Recover MySQL from Binlog

The prerequisite for recovering data from Binlog is that the MySQL Binlog must be turned on. If the Binlog log is not turned on, ignore this method. You can check the MySQL configuration file if Binlog is enabled. The log location is generally in the /var/lib/mysql directory.

Step 1. log in to MySQL and use the command to view Binlog.

• # cat /etc/my.cnf
• # mysql -uroot -p
• mysql> show variables like'log_bin%';
• # ll /home/programs/mysql-5.6.26/data/mysql-bin*

Step 2. Find the wrong statement in Binlog.

You can find the execution time of the error statement in the Binlog, and restore the logs. You can also skip this step and directly restore the entire Binlog. Then, open the SQL file and delete the error statement.

• # sudo mysqlbinlog --base64-output=DECODE-ROWS -v -d ids --start-datetime '2016-10-11 15:22:53' mysql-bin.000001 > /home/stack/data.sql

Step 3. Recover MySQL from Binlog

Use MySQL Binlog command to directly restore the Binlog log to the SQL script, and you can specify the time of the start and the end. 

If multiple Binlog files are generated from the last backup (it is recommended to refresh the Binlog files at the same time as the backup) until the recovery time. Then, export them to SQL and import them into the database in order from smallest to largest.

• # sudo mysqlbinlog --base64-output=DECODE-ROWS -v -d ids --start-datetime '2016-10-11 15:22:53' mysql-bin.000001 > /home/stack/data.sql

Step 4. Recover data to MySQL

When you are restoring data, there may be repeated data errors. It is recommended to use the -f parameter to ignore it.

• # mysql -uroot -p -f ids < data.sql

Conclusion

That's all about MySQL database. If you have enabled Binlog, Method 2 is recommended. If you don't have any backup, Method 1 is recommended. EaseUS data recovery software can recover FRM, MYD, MYI files, and more.
