If you are using Ubuntu 16.04 LTS we provide the latest stable releases of stellar-core and stellar-horizon in Debian binary package format.
You may choose to install these packages individually, this offers the greatest flexibility but will require manual creation of the relevant configuration files and the configuration of a PostgreSQL database.
Alternatively you may choose to install the stellar-quickstart package which configures a Testnet stellar-core and stellar-horizon both backed by a local PostgreSQL database.
In order to use our repository you will need to add our GPG public key to your system and create a sources file.
The key we use (A136B5A6), is available from https://pgp.mit.edu with fingerprint:
AEAF 01EE A6CA FCEF DDAE 8AA7 0463 8272 A136 B5A6
wget -qO - https://apt.stellar.org/SDF.asc | sudo apt-key add -
echo "deb https://apt.stellar.org/public stable/" | sudo tee -a /etc/apt/sources.list.d/SDF.list
The stellar-quickstart package configures a local stellar-core and stellar-horizon instance backed by a local PostgreSQL connecting to the SDF Testnet. Once installed you can easily modify either the stellar-core or stellar-horizon configs to suit your needs or to connect to the SDF Pubnet for example.
# sudo apt-get update && sudo apt-get install stellar-quickstart # install packages
# sudo systemctl start stellar-core # start up stellar-core
# stellar-core-cmd info # check/wait until stellar-core is in synch
# sudo systemctl start stellar-horizon # start up stellar-horizon
The stellar-quickstart package configures 2 databases, stellar and horizon. Access to these databases is managed via the stellar PostgreSQL role and it's corresponding stellar system user.
# sudo -u stellar psql -d stellar
psql (9.5.10)

Once you are comfortable with the various packages that stellar-quickstart brings in as dependencies, we highly recommend that you switch to installing the individual packages directly.
For this you will need to configure PostgreSQL which unfortunately is out of the scope of this document.
stellar-quickstart is a configuration package that through it's dependencies pulls in the required packages.
| Package | Dependencies | Comments |
|---|---|---|
| stellar-core | stellar-core-utils | installs stellar-core binary, systemd service, logrotate script, documentation |
| stellar-core-utils | none | installs useful command line tools (stellar-core-cmd) |
| stellar-core-postgres | stellar-core, PostgreSQL | configures a PostgreSQL server, creates a stellar db,role and system user |
| stellar-horizon | none | installs stellar-horizon binary, systemd service |
| stellar-horizon-postgres | stellar-horizon, PostgreSQL | configures a PostgreSQL server, creates a horizon db and stellar role, system user |
| stellar-quickstart | stellar-core-postgres, stellar-horizon-postgres | pulls in required packages via it's dependencies |
If you choose to install the individual packages, you will need to install your own configuration files as well as configure PostgreSQL.
- stellar-core: is configured by modifying
/etc/stellar/stellar-core.cfg - stellar-horizon: is configured by modifying
/etc/default/stellar-horizon
apt-get update && apt-get install stellar-coreorapt-get update && apt-get install stellar-horizon- deploy suitable configs, see docs
systemctl start stellar-coreorsystemctl start stellar-horizon
For convenience our packages install a Systemd service /lib/systemd/system/stellar-core.service or /lib/systemd/system/stellar-horizon.service. These services are loaded by default but as a precaution you will still need to start the services manually post installation.
Should you want these services to start up after a reboot, you will need to run:
systemctl enable stellar-core or systemctl enable stellar-horizon
The stellar-core Debian package installs a Logrotate script under /etc/logrotate.d/stellar-core.
Due to the way stellar-core currently manages it's logs, we are temporarily using copytruncate to rotate the logs. Unfortunately, a minimal amount of log entries may be lost with this setup. We are actively looking at ways of improving this.
You can disable automatic logrotation rm -r /etc/logrotate.d/stellar-core
/var/log/stellar/*.log {
daily
missingok
rotate 14
compress
notifempty
copytruncate
create 0640 stellar stellar
}
This simple script wraps a curl call to the stellar-core http endpoint.
