Installation

SeisComP3 is distributed in the form of tar files for different releases, Linux systems and architectures:

  • Acquisition, processing and GUIs (for each supported platform)
  • Maps (maps from the SeisComP3 releases Seattle and Zurich also work in Jakarta)
  • Documentation
  • Station configuration files (optional)

Download these from http://www.seiscomp3.org/ . This section describes the installation of the binary packages of SeisComP3 on an

  • Ubuntu 14, 64 bit system
  • openSUSE 11, 64 bit system
  • CentOS 6, 64 bit system

Requirements

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

Minimum 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, Debian 5.0, CentOS 5.3

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-jakarta-[version]-[OS]-[arch].tar.gz files to your home directory. Take care which is the right package (32 or 64-bit) for your operating system.

  • Go to home directory

    user@host:/tmp$ cd

  • Un-tar the SeisComP3 binary packagemake

    user@host:~$ tar xzf seiscomp3-jakarta-[version]-[OS]-[arch].tar.gz

  • Un-tar the SeisComP3 map package into seiscomp3/share/maps

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

  • If desired, un-tar the documentation into seiscomp3/share/doc

    user@host:~$ tar xzf seiscomp3-jakarta-[version]-doc.tar.gz

Unpacking these file creates the SeisComP3 directory structure.

Install dependencies

SeisComP3 depends on a number of additional packages shipped with each Linux distribution. The following table gives an overview (the names of packages, files or commands may differ slightly for other Linux systems):

Packages

Ubuntu 14 OpenSUSE CentOS 6 SeisComP3 component
flex flex flex Seedlink (compilation only)
libxml2 libxml2 libxml2 Seedlink, Arclink, trunk
libboost libboost boost trunk
libboost-dev libboost-dev boost-devel trunk (compilation only)
libncurses5 libncurses ncurses trunk:scm (optional)
libncurses5-dev libncurses-dev ncurses-devel trunk:scm (compilation only, optional)
mysql-client libmysqlclient mysql trunk (only if MySQL is used)
mariadb-client   mariadb-client trunk (only if MariaDB is used)
libmysqlclient-dev libmysqlclient-dev mysql-devel trunk (compilation only if enabled)
mysql-server mysql-server mysql-server trunk (only if MySQL is used locally)
mariadb-server   mariadb-server trunk (only if MariaDB is used locally)
libpq5 libpq5 postgresql trunk (only if PostgreSQL is used)
libpq-dev libpq-dev postgresql-devel trunk (compilation only if enabled)
libqt4-dev libqt4 qt4 trunk (only GUI should be used)
python-dev python-dev python-devel trunk (compilation only)
festival festival 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. Read the section System management for more detailed instructions. For example, to install the dependencies for using the MySQL database, give ‘mysql-server’ as parameter.

user@host:~$ seiscomp3/bin/seiscomp install-deps base mysql-server
Distribution: Ubuntu 10.04
[sudo] password for sysop:
Reading package lists... Done
Building dependency tree
Reading state information... Done
...

If your distribution is not supported by install-deps , install the above packages manually:

Ubuntu version

user@host:~$ cd seiscomp3/share/deps/ubuntu/[version]
...

OpenSUSE version

user@host:~$ cd seiscomp3/share/deps/sles/[version]
...

CentOS version

user@host:~$ cd seiscomp3/share/deps/centos/[version]
...

su root
bash install-mysql-server.sh
bash install-postgresql-server.sh
bash install-base.sh
bash install-gui.sh
bash install-fdsnws.sh
...

or contact the SeisComP3 developpers to add support for your distribution.

SQL configuration

  • For better performance with a MySQL database, adjust the memory pool size. Test the default of the buffer_pool_size before making the change:

    mysql -u sysop -p
show variables like 'innodb_buffer_pool_size';

    The optimum buffer_pool_size depends on your system (RAM size) and only needs to be set if required. Choose your preferred value:

    • Recommended value: 512M
    • Minimum value: 64M

    Additionally, reduce the database hard drive synchronization and make both adjustments in the section [mysqld]:

    [mysqld]
innodb_buffer_pool_size = <your value>
innodb_flush_log_at_trx_commit = 2

    Note: The location of the configuration can differ between distributions. The locations are given below for different Linux distribution.

    OpenSUSE

    /etc/my.cnf

    Ubuntu 14

    /etc/mysql/my.cnf or /etc/mysql/conf.d/*

    Ubuntu 16

    /etc/mysql/mariadb.conf.d/50-server.cnf

    CentOS

    /etc/my.cnf

    Please read the documentation of your distribution. root privileges may be required to make the changes.

  • After adjusting the parameters, MySQL needs to be restarted. One can run

OpenSUSE

user@host:~$ sudo rcmysql restart

Ubuntu 14

user@host:~$ sudo restart mysql

Ubuntu 16

user@host:~$ sudo systemctl restart mysql

CentOS

user@host:~$ su root
user@host:~$ /sbin/service mysqld restart

  • To start MySQL automatically during boot set

    OpenSUSE

    user@host:~$ insserv mysql

    Ubuntu 14, 16

    user@host:~$ sudo update-rc.d mysql defaults

    CentOS

    user@host:~$ su root
user@host:~$ /sbin/chkconfig mysqld on

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

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 Python 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 e.g. 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.
