An appealing article we have located which has several things to learn from. You may wish to have a look and find what you think.
The MySQL database is extensively used as part of the LAMP (Linux, Apache, MySQL, and PHP/Python/Perl) stack. All these applications are very popular because these are freely available, fast, very reliable and secure. For these reasons the applications made on the LAMP stack are hugely preferred for the Web-based applications. But as they say, nothing is perfect in this world. These applications too can get stuck because of table corruption in MySQL databases thereby making all the concerned data inaccessible and insecure. Such instances can appear because of various causes such as abrupt system shutdown, virus infections, file header corruption, etc. You can try out several table repair methods to fix the problem. If you do not succeed in MySQL recovery, then the best option is to use a third-party MySQL repair software.
To relate with this matter, consider a scenario in which you are working on a MySQL table. In this, you try to run a query but it fails to execute. The following error message is displayed after this problem happens:
“MySQL server has gone away”
The main causes of this problem are:
The MySQL connection is closed because of server time out.
The query is too large or complex to execute.
You are trying to run the query on the closed connection.
The connection on the client side is closed.
The MySQL table is corrupt.
You can perform the following methods to fix the problem:
Try to establish the connection again with the server and try that query again to ensure whether this is a server-related problem.
Run Optimize Table command.
If it shows the following error message, then you should perform the steps given after the error message:
ERROR 1030 (HY000): Got error 28 from storage engine
Add the following line to the my.cnf file:
Stop the MySQL server and restore the backup to the “mysql” folder.
Now restart the MySQL server and try that query again.
It should work fine now.
Well, if the query does not work even now, then there must be a more serious corruption with the MySQL table. In such cases, I would suggest you to take the services of a third-party MySQL repair software to repair MySQL database. These tools use non-destructive algorithms to safely recover MySQL database.
