Installation

SeisComP3 is distributed in the form of tar files:

  • Acquisition, processing and GUIs (for each supported platform)
  • Maps
  • Station configuration files (optional)

This section describes the installation of the binary packages of SeisComP3 on an openSUSE 11.1 64 bit system with KDE desktop profile.

Requirements

The hardware requirements for a seismic system depend on the size of the operated station network.

Minimal requirements are:

CPU 1
RAM 2 GB
HDD 20 GB
OS SUSE 10.2/3 32/64bit, SUSE 11 32/64bit, (K)Ubuntu 7/8 32/64bit

In case large networks (>100 stations) are operated, a distributed system is recommended. Normally a SeisComP3 system is separated in several subsystems. A separation of data acquisition, processing and graphical user interfaces is useful to permit stable performance.

The minimum specifications of the system should be:

Data acquisition system:

CPU 1
RAM 2 GB
HDD Raid1/5/0+1 with >= 200GB

Processing system:

CPU 2
RAM 4 GB
HDD Raid1/5/0+1 with >= 100GB

GUI system:

CPU 2
RAM 4 GB
HDD > 50 GB

Installation procedure

The next steps describe the installation of SeisComP3 with the prepared tar.gz files.

  • Log in as user (e.g. sysop)

  • Copy one of the seiscomp3-zurich-[version]-[OS]-[arch].tar.gz files to your home directory. Take care which is the right package for your system also for 32 and 64bit.

  • Go to home directory

    user@host:/tmp$ cd
    
  • Untar the SeisComP3 binary package

    user@host:~$ tar xzf seiscomp3-zurich-[version]-[OS]-[arch].tar.gz
    
  • Untar the SeisComP3 map package

    user@host:~$ tar xzf seiscomp3-maps.tar.gz
    

Now everything is installed and the system can be configured. The next chapter chapter explains the first steps.

Install dependencies

SeisComP3 depends on a number of additional packages shipped with each Linux distribution. The following table gives an overview:

Package SC3 component
flex Seedlink (compilation only)
libxml2 Seedlink, Arclink, trunk
libboost trunk
libboost-dev trunk (compilation only)
libncurses trunk:scm (optional)
libncurses-dev trunk:scm (compilation only, optional)
libmysqlclient trunk (only if MYSQL is used)
libmysqlclient-dev trunk (compilation only if enabled)
mysql-server trunk (only if MYSQL is used locally)
libpq5 trunk (only if PostgreSQL is used)
libpq-dev trunk (compilation only if enabled)
libqt4 trunk (only GUI should be used)
python-dev trunk (compilation only)
festival trunk (optional voice alert)

First the environment has to be set up. The seiscomp tool comes with the command install-deps which installs required packages. To use MYSQL, give 'mysql-server' as parameter. If your distribution is not supported by install-deps, install the above packages or contact us to add support for your distribution.

user@host:~$ seiscomp3/bin/seiscomp install-deps base mysql-server
Distribution: Ubuntu 10.04
[sudo] password for sysop:

SQL configuration

  • For better performance with a MYSQL database, adjust the following parameters:

    • "innodb_buffer_pool size = 64M"
    • "innodb_flush_log_at_trx_commit = 2"

    The location of the configuration can differ between distributions. For OpenSUSE it is in /etc/my.cnf whereas Ubuntu uses /etc/mysql/my.cnf respectively /etc/mysql/conf.d/*. Please read the documentation of your distribution .

    After adjusting the parameters, MYSQL needs to be restarted. If you are running OpenSUSE you can run

    $ sudo rcmysql restart
    

    whereas Ubuntu requires

    $ sudo restart mysql
    
  • To start MySQL automatically during boot set in OpenSUSE

    user@host:~$ insserv mysql
    

Directory structure

The directory structure of the installed system is described with the following table.

Directory Description
bin The user module binaries.
lib The base library directory used by all modules.
lib/python The pyton library directory.
man The manual pages.
sbin The system/service/server binaries such as seedlink.
var Variable files whose content is expected to continually change.
var/log Log files of started modules. Usually modules log either to syslog or ~/.seiscomp3/log. This directory contains the logs of the start of each module.
var/lib Default directory for files created by modules such as the waveform ringbuffer of SeedLink or the waveform archive created by slarchive.
var/run Contains the .run and .pid files of modules started by seiscomp.
include SDK header files for all libraries.
share Application data such as maps, cities.xml and others.
share/templates Template files used by eg SeedLink to create its native configuration.
etc Configuration directory.
etc/descriptions Contains all XML module descriptions.
etc/defaults The default configuration files. This directory is read as first when a module starts.
etc/init Module init scripts called by seiscomp.
etc/key Station configurations and module bindings.
