Setting

Version

See System Requirements and Compatibility.

The following configuration parameters must be set in my.cnf

datadir

Ensure that the data directory being used has sufficient space for the initial period of PhixFlow operation.

This is in the [mysqld] section of the my.cnf file.

binlog_format

mixed

This must be added to the [mysqld] section of the my.cnf file.

sql_generate_invisible_primary_key

0

wait_timeout

28800 (this is the default, but some installation processes set this to a much lower value)

This must be in the [mysqld] section of the my.cnf file.

The following configuration parameters can optionally be set in my.cnf

log_bin_trust_function_creators

1

This must be in the [mysqld] section of the my.cnf file.

This setting is needed because PhixFlow's migration scripts sometimes require the use of non-deterministic functions

sql_generate_invisible_primary_key

0. If you do not set this, then at some point you may enounter an upgrade where you are required to turn this setting on for the duration of the upgrade - this will be noted in the Special Upgrade Instructions

require_secure_transport

1

This must be in the [mysqld] section of the my.cnf file.

This setting requires that all client connections are encrypted.

Example

If you add all parameters above to my.cnf, including the optional parameters, then the [mysqld] section of your my.cnf file should look something like this:

...

languagebash
echo "[mysqld]
datadir = /var/lib/mysql
wait_timeout = 28800
binlog_format = mixed
