OmniDB is a client for managing MySQL, MariaDB, PostgreSQL, and SQLite databases. It has two versions, a desktop version which we told you about some time ago and a self-hosted version. We will talk about the latter.

This client allows us to install it on our server and access it from anywhere. Or even use it in an internal network for the same purposes. With OmniDB we will be able to do what it is expected to do, query, modify and manage databases; besides this, it includes SQL Editors with autocomplete and others.

On the other hand, work unification is the order of the day thanks to Tab System with multiple contexts.

So, let’s get started.

Install OmniDB Server on Ubuntu 20.04

The process is quite simple thanks to the DEB package that the developers leave us. So, connect to your server and update it.

sudo apt update
sudo apt upgrade

Now, download OmniDB DEB package

cd /tmp/
wget https://github.com/OmniDB/OmniDB/releases/download/3.0.3b/omnidb-server_3.0.3b_linux_x86_64.deb

Configuring OmniDB Server

The OmniDB installation includes a Systemd service to manage the program.

The first thing to do is to check the status of this service.

sudo systemctl status omnidb.service
● omnidb.service - OmniDB server daemon
     Loaded: loaded (/etc/systemd/system/omnidb.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2021-08-04 15:09:06 CEST; 1min 31s ago

Aug 04 15:09:10 osradar bash[1498]: Press Ctrl+C to exit

As you can see, it is running on http://127.0.0.1:8000 but since we are installing it on a server, this is not useful.

So, stop the service.

sudo systemctl stop omnidb.service

Now, initialize but with the -p options to define a port and -H to define the host.

omnidb-server -p 8080 -H 0.0.0.0.0

Starting server OmniDB 3.0.3b at 0.0.0.0:8080.
Open OmniDB in your favorite browser
Press Ctrl+C to exit

Now yes. When you open the web browser and visit http://ipserver:8080 you can see the login screen.

Press CTRL + C to finish running OmniDB because we need to create a new user.

This can be done as follows:

omnidb-server -u angelo 123456

Replace angelo with your username and 123456 with a more appropriate password.

Now run it again and you will be able to log in. You will see the login screen and then the welcome screen.

And you will be able to edit a connection.

Optional: Using Nginx as a reverse proxy

The default is that we have to use a reverse proxy like Nginx and from there manage the connection to OmniDB. This is very well detailed in the official documentation.

So, if OmniDB is running, stop it. Either using the service or manually.

Install Nginx

sudo apt install nginx

And create a new configuration file for Nginx

sudo nano /etc/nginx/sites-available/omnidb

Now add the following

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    include snippets/ssl-domain.conf;
    include snippets/ssl-params.conf;
    server_name domain.org;
    client_max_body_size 75M;

    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header   X-Real-IP $remote_addr;
        proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Ssl https;
        proxy_set_header   X-Forwarded-Proto https;
        proxy_set_header   X-Forwarded-Port 443;
        proxy_set_header   Host $host;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Remember to replace server_name with your domain.

Save the changes and close the editor.

Check the Nginx syntax for an error.

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

For all this to work, it is necessary to edit the default OmniDB configuration file.

sudo nano ~/.omnidb/omnidb-server/config.py

And make sure to leave these values as follows

LISTENING_ADDRESS = '127.0.0.1'
LISTENING_PORT = 8000IS_SSL = False
SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True

Save the changes and close the editor.

The next step is to create an SSL certificate with Let’s Encrypt. So, install certbot and the Nginx plugin.

sudo apt install certbot python3-certbot-nginx

And generate the certificate

sudo certbot --nginx -d [domain]

Put your domain and accept the license terms and you are done.

Finish the process by starting the OmniDB service and restarting Nginx.

sudo systemctl start omnidb
sudo systemctl restart nginx

Now login from your browser in a secure way.

Conclusion

Tools like OmniDB are very welcome because they allow us to have flexibility in accessing our databases. With this tool, you can set up a web interface that you can access from anywhere to manage a database anywhere. So, enjoy it.
