Once the system is installed it needs to be configured. The central tool to configure and control the system is seiscomp which is explained more deeply in the next chapter.
To configure SeisComP3 initially, run seiscomp setup. This is the successor of the former ./setup script.
user@host:~$ seiscomp3/bin/seiscomp setup
====================================================================
SeisComP setup
====================================================================
This initializes the configuration of your installation.
If you already made adjustments to the configuration files
be warned that this setup will overwrite existing parameters
with default values. This is not a configurator for all
options of your setup but helps to setup initial standard values.
--------------------------------------------------------------------
Hint: Entered values starting with a dot (.) are handled
as commands. Available commands are:
quit: Quit setup without modification to your configuration.
back: Go back to the previous parameter.
help: Show help about the current parameter (if available).
If you need to enter a value with a leading dot, escape it
with backslash, e.g. "\.value".
--------------------------------------------------------------------
This will ask for initial settings as database (if package trunk is installed) parameters and the logging backend.
Organization name []:
Sets the organisation name printed e.g. when you say hello to Seedlink or Arclink.
Enable database storage [yes]:
Enables or disables the database for the system. This option should be left enabled unless all modules should connect to remote processing machine which is already available. The database is required to store inventory information as well as processing results. The database is the central storage for all trunk modules and the default request handler of Arclink.
0) mysql
MySQL server.
1) postgresql
Postgresql server. There is currently no support in setup to create the
database for you. You have to setup the database and user accounts on
your own. The database schema is installed under share/db/postgresql.sql.
Database backend [0]:
If the database is enable the database backend can be selected. SeisComP3 supports two main backends: MySQL and postgresql. Select the backend to be used here but be prepared that only for the MySQL backend the setup can help to create the database and tables for you. If you are using postgresql you have to provide a working database with the correct schema. The schema files are part of the distribution and can be found in share/db/postgresql.sql.
Note
As of PostgreSQL version 9 the default output encoding has changed to hex. In order to fix issuses with seiscomp3 log in to your database and run the following command.
ALTER DATABASE seiscomp3 SET bytea_output TO 'escape';
Create database [yes]:
If MySQL is selected it is possible to let seiscomp setup to create the database and all tables for you. If the database has been created already, say 'no' here.
MYSQL root password (input not echoed) []:
Give the MySQL root password for your database server to create the database tables. This is only required if the last question has been answered with 'yes'.
Drop existing database [no]:
If a database with the same name (to be selected later) exists already and the database should be created for you, an error is raised. To delete an existing database with the same name, say 'yes' here.
Database name [seiscomp3]:
Database hostname [localhost]:
Database read-write user [sysop]:
Database read-write password [sysop]:
Database public hostname [localhost]:
Database read-only user [sysop]:
Database read-only password [sysop]:
Setup the various database options valid for all database backends. Give .help for more information.
If all question have been answered the final choice needs to be made to either create the initial configuration, go back to the last question or to quit without doing anything.
Finished setup
--------------
P) Proceed to apply configuration
B) Back to last parameter
Q) Quit without changes
Command? [P]:
After the installation no module is activated for auto start. If seiscomp start is called, nothing will happen. To activate a set of modules, seiscomp enable needs to be called with a list of modules. To enable a processing system with Seedlink for data acquistion, use:
user@host:~$ seiscomp3/bin/seiscomp enable seedlink \
scautopick scautoloc scamp scmag scevent
enabled seedlink
enabled scautopick
enabled scautoloc
enabled scamp
enabled scmag
enabled scevent
A successive call of seiscomp start will then start all enabled modules. This is also required to restart enabled modules with seiscomp check. But before starting seiscomp, stations need to be added and the configuration needs to be updated.
SeisComP3 comes with various importers to add networks and stations including full response information.
import_inv is the tool to import inventory data into SeisComP3.
user@host:~$ seiscomp3/bin/seiscomp exec import_inv dlsv inventory.dataless
This will import a dataless SEED volume into etc/inventory/inventory.dataless.xml.
Repeat this step for all inventory data you want to import.
The configuration of modules and bindings is explained in Configuration. To add bindings in a more convenient way, start scconfig.
user@host:~$ seiscomp3/bin/seiscomp exec scconfig
To update the configuration when new stations have been added or modified, seiscomp update-config needs to be run. This creates configuration files of modules that do not use the configuration directly, writes the trunk bindings to the database and sychronizes the inventory with the database.
user@host:~$ seiscomp3/bin/seiscomp update-config
[output]
After the configuration has been updated and the inventory has been synchronized, call seiscomp start to start all enabled modules:
user@host:~$ seiscomp3/bin/seiscomp start
starting seedlink
starting scautopick
starting scautoloc
starting scamp
starting scmag
starting scevent
Now the system should run. To check everything again, seiscomp check can be run which should print is running for all started modules. If everything is working, the analysis tools can be started, e.g. MapView.
user@host:~$ seiscomp3/bin/seiscomp exec scmv
