Getting MYSQL server has gone away when importing database from .sql file
Problem: You are trying to import a .sql file using the command line mysql command but it is unsuccessful as follows:
# mysql -u douser -pdbpass yourdb < db_file.sql ERROR 2006 (HY000) at line XXXXX: MySQL server has gone away
The solution is to edit /etc/my.cnf and add the following line to the [mysqld] section:
Then restart mysql:
# service mysqld restart
Re-run your import query (you may need to delete the partly database first and re-create it) and it will now succeed.
