Configuration File

You can save configuration settings for MySQL remoting in a config file. The file must be structured in the INI file format. Specify this file with the -f command-line option. The config file can have the following sections:

[mysqld]

In the mysqld section, use the following properties to configure the MySQL daemon:


	Name	Description
	port	The port number to use to listen for TCP/IP connections. The default port is 3306.
	max-connections	The maximum number of allowed TCP/IP connections. 25 is the default.
	session-timeout	The session timeout time in seconds. The default timeout is 20 seconds.
	logfile	The full path of the log file.
	verbosity	The verbosity of the log. 1 is informational. Levels up to 5 add the following subsequent details: (2) HTTP headers, (3) the HTTP body, (4) transport-level communication including SSL, and (5) interface commands and other data source communication.
	logrotationscheme	The interval at which to truncate the logs. The options are 1 (daily in the format [MyFileName]_2016_3_21.txt), 2 (weekly in the format [MyFileName]_Week_5.txt, where 5 is the fifth week in the year), and 3 (monthly in the format [MyFileName]_2016_3_21.txt). The default is 2.
	ssl-cert	The path to the SSL certificate.
	ssl-subject	The subject of the SSL certificate.
	ssl-password	The password of the SSL certificate.

[databases]

In the databases section, define keys that map the MySQL database to Elasticsearch connection strings. Clients connect to the MySQL database defined here. To connect to Elasticsearch, the driver uses the connection string that corresponds to this key.

[databases]
Elasticsearch = "Server=127.0.0.1;Port=9200;"

[users]

In the users section, define the usernames and passwords of the users of the server. If the acl section is not defined, all users have access to all databases.

[mysql_vars]

In the mysql_vars section, define system variables for the MySQL server. The standard variables are supported. Below are several examples:


	Name	Description
	version_comment	This value is hard-coded as CData JDBC Driver for Elasticsearch (MySQL Remoting).
	character_set_client	The character_set used in statements sent by the client.

[acl]

In the acl section, allow users to access Elasticsearch databases. Databases must be defined in the databases section. Users must be defined in the users section. Use commas to separate users authorized to access the specified database.

Example Config File

Below is an example config file. The example includes all properties required to configure the server. It also shows how to configure access control for several users and Elasticsearch instances.

[mysqld]
port = 3306
max-connections = 25
session-timeout = 20
logfile = ElasticsearchRemotingLog.txt
verbosity = 2
ssl-cert = "CData.JDBC.Elasticsearch.Remoting.pfx"
ssl-subject = <subject>
ssl-password = <password>

[databases]
Elasticsearch = "Server=127.0.0.1;Port=9200;"
Elasticsearch_ReadOnly = "Server=127.0.0.1;Port=9200;ReadOnly=True"

[users]
root = <password>
test = <password>

[mysql_vars]
version_comment =  "CData JDBC Driver for Elasticsearch (MySQL Remoting)"

[acl]
Elasticsearch = root
Elasticsearch_ReadOnly = root, test

You can further restrict the allowed options by passing in options on the command line. See CLI Options for more information.
