Metabase is a free and open-source business intelligence tool that can be used to search data sets and display information. It is a simple and powerful analytics tool that helps you to learn from your company’s data without any technical knowledge. It allows you to generate charts and dashboards, ask queries without using SQL, and see detailed information about rows in your Database.

Metabase is the right choice for you if you are looking for a high performance database lookup platform for your business.

In this tutorial, we will explain how to install Metabase on Ubuntu 20.04 with Nginx and Let’s Encrypt SSL.

Prerequisites

  • A server running Ubuntu 20.04.
  • A valid domain name pointed with your server IP.
  • A root password is configured the server.

Install Java

Metabase is a Java-based application. So Java must be installed in your server. You can install it with the following command:

apt-get install openjdk-11-jdk openjdk-11-jre -y

After successful installation, you can verify Java version with the following command:

java -version

You should see the following output:

openjdk version "11.0.8" 2020-07-14
OpenJDK Runtime Environment (build 11.0.8+10-post-Ubuntu-0ubuntu120.04)
OpenJDK 64-Bit Server VM (build 11.0.8+10-post-Ubuntu-0ubuntu120.04, mixed mode, sharing)

Once you are finished, you can proceed to the next step.

Install and Configure MariaDB

Next, you will need to install the MariaDB database server in your system. You can install it by running the following command:

apt-get install mariadb-server -y

Once the MariaDB server has been installed, log in to the MariaDB shell with the following command:

mysql

Once login, create a database and user for Metabase with the following command:

MariaDB [(none)]> CREATE DATABASE metabase;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON metabase.* TO 'metabase'@'localhost' IDENTIFIED BY "password";

Next, flush the privileges and exit from the MariaDB shell with the following command:

MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;

Once you are finished, you can proceed to the next step.

First, create a directory for Metabase inside /opt directory with the following command:

mkdir /opt/metabase

Next, change the directory to /opt/metabase and download the latest version of Metabase with the following command:

cd /opt/metabase
wget https://downloads.metabase.com/v0.36.2/metabase.jar

Next, you will need to create a separate user and group to run Metabase. You can create them with the following command:

addgroup --quiet --system metabase
adduser --quiet --system --ingroup metabase --no-create-home --disabled-password metabase

Next, change the ownership of the /opt/metabase to metabase and give proper permission with the following command:

chown -R metabase:metabase /opt/metabase
chmod -R 755 /opt/metabase

Once you are finished, you can proceed to the next step.

Next, you will need to create a systemd service file to manage the Metabase service. You can create it with the following command:

nano /etc/systemd/system/metabase.service

Add the following lines:

[Unit]
Description=Metabase server

[Service]
WorkingDirectory=/opt/metabase/
ExecStart=/usr/bin/java -jar /opt/metabase/metabase.jar
User=metabase
Type=simple
Restart=on-failure
RestartSec=10

[Install]
WantedBy=multi-user.target

Save and close the file then reload the systemd daemon with the following command:

systemctl daemon-reload

Next, start the Metabase service and enable it to start at system reboot with the following command:

systemctl start metabase
systemctl enable metabase

You can now verify the status of Metabase with the following command:

systemctl status metabase

You should see the following output:

? metabase.service - Metabase server
     Loaded: loaded (/etc/systemd/system/metabase.service; disabled; vendor preset: enabled)
     Active: active (running) since Sat 2020-08-01 10:14:02 UTC; 12s ago
   Main PID: 9650 (java)
      Tasks: 18 (limit: 2353)
     Memory: 150.2M
     CGroup: /system.slice/metabase.service
             ??9650 /usr/bin/java -jar /opt/metabase/metabase.jar

Aug 01 10:14:02 ubuntu2004 systemd[1]: Started Metabase server.
Aug 01 10:14:05 ubuntu2004 java[9650]: 08-01 10:14:05 INFO metabase.util :: Loading Metabase...
Aug 01 10:14:06 ubuntu2004 java[9650]: 08-01 10:14:06 INFO metabase.util :: Maximum memory available to JVM: 498.0 MB

At this point, Metabase is started and listening on port 3000. You can check it with the following command:

netstat -tunelp | grep 3000

You should see the following output:Advertisement

tcp6       0      0 :::3000                 :::*                    LISTEN      109        35366      9650/java

Next, you will need to configure Nginx as a reverse proxy for Metabase. First, install the Nginx web server with the following command:

apt-get install nginx -y

After installing Nginx, create a new Nginx virtual host configuration file with the following command:

nano /etc/nginx/sites-available/metabase.conf

Add the following lines:

upstream metabase {
  server 127.0.0.1:3000;
}

server {
    listen 80;
    server_name metabase.linuxbuz.com;
    access_log /var/log/nginx/metabase.linuxbuz.com-access.log;
    error_log /var/log/nginx/metabase.linuxbuz.com-error.log;

    location / {
        proxy_pass http://metabase/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $http_host;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forward-Proto http;
        proxy_set_header X-Nginx-Proxy true;

        proxy_redirect off;
    }
}

Save and close the file when you are finished. Then, activate the Nginx virtual host with the following command:

ln -s /etc/nginx/sites-available/metabase.conf /etc/nginx/sites-enabled/

Next, verify the Nginx for any configuration error with the following command:

nginx -t

You should see the following output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Finally, restart the Nginx service to apply the changes:

systemctl restart nginx

At this point, Nginx is configured to serve Metabase on port 80. You can now proceed to the next step.

First, you will need to install the Certbot Lets Encrypt client to install and manage SSL for your domain. You can install the Certbot client with the following command:

apt-get install python3-certbot-nginx -y

Once installed, secure the Metabase website with Let’s Encrypt SSL with the following command:Advertisement

certbot --nginx -d metabase.linuxbuz.com
