Installation on Ubuntu¶
You will …
Make a basic SeisComP installation
Pre-requisites for this tutorial:
Run a SeisComP executable
Run a SeisComP GUI program
Time range estimate:
You may install SeisComP by:
Installing pre-compiled release packages including binaries, maps and documentation.
Get your Linux System ready¶
First you need to get your Linux system ready. The following documentation refers to Ubuntu 20.04, but the steps for other Ubuntu versions are similar.
Add a new user. Throughout our documentation, this user is called sysop.
$ sudo adduser sysop $ sudo addgroup admin $ sudo usermod -a -G admin,adm,audio sysop
Check the size and the architecture. This is espcially required when installing pre-compiled packages:
$ df -h $ cat /etc/issue $ uname -m
Compare the available disk space with the requirements given in the Installation section. If ‘uname’ shows ‘i686’, you have a 32-bit system; if you see ‘x86_64’, you have 64-bit.
Install from source code¶
Install pre-compiled release packages¶
You may download and installed pre-compile SeisComP binary package, maps and documentation.
Download the appropriate SeisComP binary package taking into account your Linux distribution and the architecture. Get the package from the SeisComP package downloader 1 or gempa GmbH 2. Packages are available for Ubuntu and other Linux flavors such as CentOS and Debian.
The SeisComP packages received from gempa GmbH contain the documentation for the respective version and no separate download is required.
seiscomp*files (binary package, maps and documentation) you will find in your home or downloads directory. For SeisComP in version 4.0.0 this is:
$ cd $ tar xzf seiscomp-4.0.0-ubuntu20.04-x86_64.tar.gz $ tar xzf seiscomp-maps.tar.gz $ tar xzf seiscomp-4.0.0-doc.tar.gz $ ls seiscomp bin etc include lib man sbin share
Install all dependencies needed and prepare the environment.
This should be automatic for most distributions. Simply run the install script:
$ ~/seiscomp/bin/seiscomp install-deps base Distribution: Ubuntu 20.04
This will generally prompt for your user’s password to allow sudo to install packages on your system.
On Ubuntu 18, Python 3 is installed, but not Python. Get it first:
$ sudo apt-get install python libqtgui4
On Ubuntu 20 and newer, you may need libpython3-dev before you can use “install-deps”:
$ sudo apt-get install libpython3-dev
Alternatively, for Mint 18 (Ubuntu 16.04):
$ sudo apt-get update $ sudo apt-get install libxml2 libboost-filesystem1.58.0 libboost-iostreams1.58.0 libboost-thread1.58.0 libboost-program-options1.58.0 libboost-regex1.58.0 libboost-signals1.58.0 libboost-system1.58.0 libssl1.0.0 libncurses5 libmysqlclient20 libpq5 libpython2.7 python-numpy mysql-server mysql-client libqtgui4 libqt4-xml libqt4-opengl libqt4-sql-sqlite
OPTIONAL. You may set some environment variables. For bash users, print the environment variables and copy them to your
$ ~/seiscomp/bin/seiscomp print env export SEISCOMP_ROOT=/home/sysop/seiscomp export PATH=/home/sysop/seiscomp/bin:$PATH export LD_LIBRARY_PATH=/home/sysop/seiscomp/lib:$LD_LIBRARY_PATH export PYTHONPATH=/home/sysop/seiscomp/lib/python:$PYTHONPATH export MANPATH=/home/sysop/seiscomp/share/man:$MANPATH export LC_ALL=C source /home/sysop/seiscomp/share/shell-completion/seiscomp.bash
The path to your home directory will likely differ from /home/sysop as shown above. Cut and paste your own output from the seiscomp print env command, not what is shown here. Edit your
.bashrcfile, inserting the command from the output.
$ vi .bashrc
Then reload the contents of
.bashrcin your current environment
$ source ~/.bashrc
After this, you won’t have to type ~/seiscomp/bin/seiscomp as the seiscomp command will be added to your shell’s path.
If, when you attempt to run a SeisComP command such as scconfig or scolv, you receive an error message like:
scconfig: command not found
then the most likely explanation is that you have not set your SeisComP environment variables correctly.
Run the seiscomp command with the full path to where you installed. The seven lines of output are not actually run by the ‘seiscomp print env’ command; you need to cut and paste them into your shell to run them. You can also add these to your
.profile, or equivalent file with commands to be run every time you log in.
Database. For a MariaDB installation:
$ seiscomp install-deps mariadb-server
or a MySQL installation:
$ seiscomp install-deps mysql-server
Also, for better performance with a MySQL database, adjust the memory pool size and restart MySQL, as described under “SQL configuration” in the Installation section.
For PostgreSQL, also see the detailed Installation instructions.
For Ubuntu 18.04 and newer, take care with MySQL installation. Before the next step, you must set a root password for MySQL or MariaDB (not the Linux root password!).
$ sudo mysql -e “ALTER USER root@localhost IDENTIFIED WITH mysql_native_password BY ‘Mypasswordisnottthis’; FLUSH PRIVILEGES;”
$ sudo mysql -e “SET old_passwords=0; ALTER USER root@localhost IDENTIFIED BY ‘Mypasswordisnottthis’; FLUSH PRIVILEGES;”
Substitute Mypasswordisnottthis by your own password and remember it – you will need it in the next step.
In case of problems, see the Internet, or the SeisComP forum thread (for logged-in forum members).
Run seiscomp setup and enter your preferred IDs and password. For the other fields, you can always accept the default values.
$ seiscomp setup
You should enter an appropriate short name (without spaces) for Agency ID and Datacenter ID. These are used for Arclink and Seedlink, and in the information describing data model objects such as origins and events.
The seiscomp command is a wrapper, which controls the SeisComP modules. See System management. Run something by typing seiscomp followed by a command:
$ seiscomp help Available commands: install-deps setup shell enable disable print help Use 'help [command]' to get more help about a command
Start scmaster. As described in the Overview, these are needed for communication between the SeisComP database and the individual SeisComP modules.
$ seiscomp start scmaster starting scmaster
Install all dependencies needed for the GUI:
$ seiscomp install-deps gui
Start the scconfig GUI
$ seiscomp exec scconfig
Learn more about scconfig in this documentation. You should see a screen/window like this.
$ seiscomp exec scrttv
After seeing the SeisComP splash screen, you’ll likely get an error message “Could not read inventory (NULL)”. After a new installation, that’s okay. Click that box away, and you’ll see a screen with “Enabled”, and “Disabled” tabs, and time along bottom axis as in the figure below. To see stations and data you will later need to add inventory and waveforms to your system.
Congratulations, you’re done with this tutorial.
