dependências
<source lang="bash">
apt update
apt install openjdk-11-jdk openjdk-11-jre
apt install mariadb-server
systemctl start mariadb
systemctl enable mariadb
mysql -u root -p
</source>

criando banco de dados
<source lang="mysql">
CREATE DATABASE metabase;
CREATE USER 'metabase_user'@'localhost' IDENTIFIED BY 'Strong_Password';
GRANT ALL ON metabase.* TO 'metabase_user'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
EXIT;
</source>

instalando
<source lang="bash">
mkdir /home/metabase
cd /home/metabase
wget https://downloads.metabase.com/v0.39.3/metabase.jar
groupadd -r metabase
useradd -r -s /bin/false -g metabase metabase
chown -R metabase:metabase /home/metabase

em /etc/rsyslog.d/metabase.conf
 if $programname == 'metabase' then /var/log/metabase.log
 & stop

<source lang="bash">
systemctl restart rsyslog.service
</source>

em /etc/default/metabase (alternativa, mas não funcionou no meu teste... deu certo inserindo no service)

iniciando metabase e habilitando para iniciar no boot
<source lang="bash">
systemctl daemon-reload
systemctl start metabase
systemctl enable metabase
</source>

=== instalando e configurando o nginx ===
<source lang="bash">
apt install nginx
</source>

em /etc/nginx/sites-available/metabase
<source lang="nginx">
server {
listen 80;
listen [::]:80;
server_name example.com;
location / {
proxy_pass http://127.0.0.1:3000;
}
}
</source>

reiniciando nginx e habilitando para iniciar no boot
<source lang="bash">
ln -s /etc/nginx/sites-available/metabase /etc/nginx/sites-enabled/metabase
systemctl daemon-reload
systemctl restart nginx
systemctl enable nginx
</source>

=== Dicas ===

Para delimitar o uso de memória RAM
 ExecStart=/usr/bin/java -Xms128m -Xmx256m -jar metabase.jar

Para verificar se o processo está rolando na porta 3000
 ss -tunelp | grep 3000

Talvez seja necessário instalar o mariadb-client (apt install mariadb-client)


=== Restaurando database em Docker ===
<source lang="bash">
docker stop metabase
docker run -d -p 3000:3000 \
-v ~/metabase-data:/metabase-data \
-e "MB_DB_FILE=/metabase-data/metabase.db" \
--name metabase metabase/metabase
cp metabase.db.* ~/metabase-data/metabase.db/
</source>
