Seon Core main configuration file

Main configuration file

Seon's main configuration file defines be basic information about database connectivity and some other, really basic information which cannot reside in the database.

Position

All Seon binaries search the configuration file at

/etc/seon.conf

but they are all aware of searching this file at a given position. For this position information, nearly all binaries have the parameter "-C" (beware of the uppercase!). Example:

$ /opt/seon/bin/seonrd -C /opt/seon/seon.conf

This example searches the config file at the given position "/opt/seon/seon.conf".

In addition, all running Seon binaries set the environment variable "Seon_CFGFILE", which is also interpreted by all binaries. An alternative way to the above example could then be:

$ export Seon_CFGFILE=/opt/seon/seon.conf
$ /opt/seon/bin/seonrd

Content

The configuration file contains textual information in the format "key=value", where no space must be existant between key, the character "=" and the corresponding value. Lines beginning with a hash sign ("#") are comments and will not be taken into account. Example:

# comment 
KEY=VALUE

Variables

Illegal defintions are:

KEY = VALUE
KEY =VALUE
KEY= VALUE

The following variables are available.

DB_HOST

Mandatory.

Resolvable hostname or IP address of the databse server. In case of MySQL, special rules apply: if the value "localhost" is used, the MySQL client library tries to connect via a compiled in socket connection, if no socket is configured. In this case, if you have any problems connecting to MySQL, examine your syslog output and check the socket availability. As a workaround, "127.0.0.1" can be configured for a forced TCP/IP connection to localhost.

DB_USER

Mandatory.

Username for the database connection. In case of MySQL, if no username is configured (left empty), the user running the program is being used.

DB_PASS

Mandatory.

Password for the database connection. Empty connection passwords are not officially supported, but may work.

DB_NAME

Mandatory.

• MySQL: Name of the database.
• DB2: Name of the database instance.

Examples

The following examples show various settings: locale and remote databases, socket connects, the possible database types and persistant connections.

local MySQL server via socket

DB_HOST=localhost
DB_USER=seon
DB_PASS=seon
DB_NAME=seon
DB_SOCKET=/var/lib/mysql.sock
DB_PORT=3306
TABLEPREFIX=seon_
MYSQLCLIENT=/usr/local/mysql/bin/mysql

remote DB2

DB_HOST=db2 DB_USER=db2inst1 DB_PASS=db2 DB_NAME=swan_hl DB_PORT=50000 TABLEPREFIX=seon_ DBTYPE=DB2

remote DB2 with persistant connections and configured server ID

DB_HOST=db2 DB_USER=db2inst1 DB_PASS=db2 DB_NAME=swan_hl DB_PORT=50000 TABLEPREFIX=seon_ MYSQLCLIENT=/usr/local/mysql/bin/mysql DBTYPE=DB2 DB_PERSISTANT_CONNECTION=1 SERVERID=5
