Managing MySQL server is one of the interesting thing for every sys admins.
In this article I’m just sharing a quick fix for the error that I got while restoring the database from its backup file. I hope this will be helpful for you guys too.
I got one error while restoring the database backup file from the command line. Error message is shown below:
# mysql database_name < database_back.sql -------- at line 4511: MySQL server has gone away. --------
Check the value for the mysql directive “max_allowed_packet” in mysql configuration file “my.cnf”. Increase the value to higher to avoid the error.
# vi /etc/my.cnf -------- max_allowed_packet=64M #try higher values if problem persist. --------
Click here for cPanel conf details.
Then restart the mysql daemon.
# service mysql restart
After restarting the mysql service try again to restore the DB backup.
That’s it!!! 🙂
