The Lianja Server on Linux

The Lianja Server service on Linux listens for requests for both the Lianja SQL Server and the Lianja Cloud Server. The Lianja Server service needs to be running and have a valid and activated license for the requested Server.

Managing the Lianja Server Service on Linux

For RedHat and other Linux variants that support the service command, the name of the Lianja Server service is lianjad and has the following options:

service lianjad start [logging] | stop | restart | status

This command should be run as root / using sudo.

Option Description
start [logging] Start the Lianja Server service.
If the optional logging argument is specified, logging is enabled. By default, log files are created in the /opt/lianja/cloudserver/tenants/public/log/ directory.
An alternative directory can be specified in the DB_LOGDIR environment variable in lianja.conf (see below).
stop Stop the Lianja Server service.
restart Restart the Lianja Server service.
status Report the status of the Lianja Server service.

Alternatively, the lianja-admin command can be used:

lianja-admin start [logging] | stop | restart [logging] | status

This command should be run as root / using sudo.

Option Description
start [logging] Start the Lianja Server service.
If the optional logging argument is specified, logging is enabled. By default, log files are created in the /opt/lianja/cloudserver/tenants/public/log/ directory.
An alternative directory can be specified in the DB_LOGDIR environment variable in lianja.conf (see below).
stop Stop the Lianja Server service.
restart [logging] Restart the Lianja Server service.
If the optional logging argument is specified, logging is enabled. By default, log files are created in the /opt/lianja/cloudserver/tenants/public/log/ directory.
An alternative directory can be specified in the DB_LOGDIR environment variable in lianja.conf (see below).
status Report the status of the Lianja Server service.

Configuration

The Lianja Server configuration file is /etc/lianja.d/lianja.conf. Edit this text file to change the configuration environment variables. The Lianja Server should be restarted to reflect changes.

DB_ROOT is defined in the /etc/lianja.d/.root file.
