If you get an error like this:
Packet for query is too large (1708726 > 1048576). You can change this value on the server by setting the 'max_allowed_packet' variable.You need to modify your MySQL server configuration file and increase the value of the max_allowed_packet property. Don't forget to restart the MySQL after any change in this file. In Debian based distros like Ubuntu, this configuration file is located at /etc/mysql/my.cnf. |
Change mysql default engine to InnoDB
Check if your MySQL installation has InnoDB engin enabled:
$ mysql -h localhost -u root -p mysql> show engines;
In order to change the default storage engine edit /etc/mysql/my.cnf and under [mysqld] section in your ini file, and add:
default-storage-engine = innodb
 |
InnoDB is the preferred engine because it support transactions. MyISAM is more responsive but does not support transactions. |
