= Server setup

== Setup scripts

`ssh` as `root`:

[source,bash]
----
ssh root@SERVER_NAME
----

Run the following (as root):

[source,bash]
----
# Install needed packages
apt update
apt install sudo python3 git -y

# Add a sudo user with the name 'admin'
sudo useradd admin
sudo usermod -aG sudo admin
sudo mkhomedir_helper admin

# Enter a new password for 'admin'
sudo passwd admin

# Break the SSH connection
exit
----

`ssh` again with the new user `admin` and password:

[source,bash]
----
ssh admin@SERVER_NAME
----

Clone the repository with `git clone` into `/home/admin/advlabdb`. Then `cd` into the new cloned repository:

[source,bash]
----
cd ~/advlabdb
----

[source,bash]
----
cp advlabdb/scripts/setup/advlabdb.conf.template advlabdb/scripts/setup/advlabdb.conf
----

Change `server_name` in `advlabdb/scripts/setup/advlabdb.conf` to your SERVER_NAME.

[source,bash]
----
cp .env.template .env
----

Generate secrets for `.env`:
[source,bash]
----
python3 advlabdb/scripts/setup/generate_secrets.py
----

Fill the secrets generated using the last script into `.env`.

Enter your SERVER_NAME in `.env`.


List all available timezones:
[source,bash]
----
sudo timedatectl list-timezones
----

Choose your timezone and enter it as showed while listing as your timezone using this command (with Europe/Berlin as example):
[source,bash]
----
sudo timedatectl set-timezone Europe/Berlin
----

Edit the file `/etc/hostname` with `sudo` such that its content is only your SERVER_NAME.

Edit the file `/etc/hosts` with `sudo` such that the first two lines are:
[source,bash]
----
127.0.0.1 localhost
127.0.1.1 SERVER_NAME SERVER_NAME_WITHOUT_DOMAIN
----

Run server setup script:
[source,bash]
----
python3 advlabdb/scripts/setup/server_setup.py
----

After reboot:

[source,bash]
----
cd ~/advlabdb
poetry run python3 -m advlabdb.scripts.setup.init_database
sudo systemctl restart gunicorn
----

Now go to your SERVER_NAME from the browser.
