- Erlang/OTP (21.0 or newer).
- LibYAML (0.1.4 or newer).
- OpenSSL (1.4.5 or newer).
- GCC (other C compilers might work as well).
Note that you need the development headers of the libraries as well. Linux
distributions often put those into separate *-dev or *-devel packages. For
example, on DEB-based distributions you'd typically install libyaml-dev and
libssl-dev, on RPM-based distributions you'll probably need libyaml-devel
and openssl-devel.
Note: If you build directly from the Git repository rather than using the official source tarball, you must download rebar3 and make it executable (
chmod +x rebar3), first.
$ curl https://eturnal.net/download/eturnal-1.4.5.tar.gz | tar -C /tmp -xzf -
$ cd /tmp/eturnal-1.4.5
$ ./rebar3 as prod tar
This generates the archive file _build/prod/rel/eturnal/eturnal-1.4.5.tar.gz.
The default installation prefix is set to /opt/eturnal, and it's assumed the
server will be executed by a user named eturnal. To change these defaults,
edit the build.config file, re-run ./rebar3 as prod tar, and adapt the
following installation instructions accordingly.
You'll need root privileges for the following commands. Therefore, call su -
or sudo -i, first.
-
Create a user for running eturnal. This step is of course only required if you're installing eturnal for the first time:
# useradd -r -m -d /opt/eturnal eturnalOtherwise, create a backup of the old installation, first:
# tar -czf /opt/eturnal-$(date '+%F').tar.gz /opt/eturnal -
Extract the archive generated above:
# cd /opt/eturnal # tar -xzf /tmp/eturnal-1.4.5/_build/prod/rel/eturnal/eturnal-1.4.5.tar.gz -
Copy the
eturnal.ymlfile to/etc(optional):# cp -i /opt/eturnal/etc/eturnal.yml /etc/ -
Start the systemd service:
# cp /opt/eturnal/etc/systemd/system/eturnal.service /etc/systemd/system/ # systemctl daemon-reload # systemctl --now enable eturnal
