mysql_adaptor

Name

mysql_adaptor — MySQL/MariaDB connector for user metadata and authentication

Description

mysql_adaptor is a service plugin for integrating mail accounts from a MySQL/MariaDB database.

Configuration directives

The usual config file location is /etc/gromox/mysql_adaptor.cfg.

connection_num
Number of SQL connections to keep active.
Default: 8
enable_firsttimepw
This flag determines whether non-LDAP users with no recorded password (empty users.password SQL column) will have the account's password set to whatever credential was passed along in the first authentication request.
Default: no
mysql_dbname

Default: email

mysql_host
The hostname/IP address for contacting the SQL server.
Default: localhost
mysql_password

Default: (unset)

mysql_port
The TCP port number for contacting the SQL server.
Default: 3306
mysql_rdwr_timeout
This sets the MYSQL_OPT_READ_TIMEOUT and MYSQL_OPT_WRITE_TIMEOUT option values on the MySQL connection.
Default: 0 (no timeout)
mysql_username

Default: root

scan_interval

Default: 1 minute

schema_upgrade

This controls what to do when a database schema update is available. Because the mysql_adaptor plugin is loaded by many programs across potentially multiple machines, the basic default is to do nothing.

host:xyz

Perform automatic schema upgrades if the program which has loaded mysql_adaptor is http(8gx) and only if http.cfg's host_id value matches xyz.

(any other value)

No automatic schema upgrades are performed in the process which has loaded the plugin. The plugin may be unable to process or produce certain data, e.g. if it relies on a table that has not yet been created. Generally, no restart is needed when that upgrade is finally performed, because SQL queries just start working. However, there may be some caches, e.g. in the zcore(8gx) address book that could remain empty until the refresh timer expires or a manual reload is triggered.

Default: host:(system_hostname)
