Configuring MySQL®
How do I set a time zone?
A time zone is specified in terms of a UTC offset. Moscow's, for instance, is '+03:00'. Time zone names are not supported.
For more information, see the MySQL® documentation.
How do I set the SQL mode (sql_mode)?
Follow the steps described in Managing databases.
What value should I set for innodb_buffer_pool_size?
Recommended parameter range:
- Minimum 25% of host RAM.
- Maximum 75% of host RAM provided that at least 1 to 1.6 GB are free for running queries, monitoring, and system processes.
How do I disable InnoDB strict mode?
By default, InnoDB strict mode is enabled. If you disable this mode using MySQL® tools, the following error will occur:
Mysql query error: (1227) Access denied; you need (at least one of) the SYSTEM_VARIABLES_ADMIN or SESSION_VARIABLES_ADMIN privilege(s) for this operation (400)
To disable strict mode, change the innodb_strict_mode parameter value via the Yandex Cloud interfaces. You should also make sure that your configuration contains no command that disables strict mode, such as $connection–>queryExecute("SET innodb_strict_mode=0");.
How do I change character sets and collation rules (CHARACTER SET, COLLATE)?
Follow the steps described in Managing databases.
How do I configure other parameters?
Editable MySQL® settings are listed in the documentation. You can use one of the available interfaces (management console, CLI, API, or Terraform) to modify these. Follow the instructions in Updating a cluster.
