We were doing a big database import in MySQL and we got this error message during the process.
Got a packet bigger than ‘max_allowed_packet’ bytes.
Here are the changes we needed to make it work. We are running on CentOS.
1. Edit /etc/my.cnf and add the following lines. The packet value we want for this example is 500M.
2. Restart MySQL.
> service mysqld restart
3. Run the MySQL import process with the max_allowed_packet parameter. Replace USERNAME, DATABASE and DUMP with the appropriate values.
> mysql --max_allowed_packet=500M -u USERNAME -p DATABASE < DUMP.sql
Wait for the import process to complete and that should be it.
