In this tutorial, we will go through the process of installing Mejiro from its source code on Fedora CoreOS. Mejiro is a web-based front-end for managing PostgreSQL databases.
Before we start, make sure you have the following prerequisites:
Before we can install Mejiro, we need to install its dependencies. One of the dependencies is the go programming language. To install go, run the following command as a sudoer:
sudo dnf install golang
Once go is installed, we will also need to install the postgresql server and its development package:
sudo dnf install postgresql postgresql-devel
Now that we have the dependencies installed, let's clone the Mejiro repository. Navigate to a directory where you want to keep the Mejiro source code and clone the repository:
git clone https://github.com/dmpop/mejiro.git
Once cloned, navigate to the Mejiro directory:
cd mejiro
To build and install Mejiro, run the following command:
sudo make install
The above command will download and install all the necessary dependencies, build Mejiro, and install it on the system.
Before we can use Mejiro, we need to configure it. Create a configuration file named config.yaml in the Mejiro directory:
nano config.yaml
Add the following configuration to the config.yaml file:
listen: ":8080"
username: "postgres"
password: "password"
database: "postgres"
sslmode: "disable"
Replace password with the actual password that you set for the postgres user during the installation of the PostgreSQL server.
Finally, we can start Mejiro by running the following command:
sudo mejiro -c config.yaml
If everything was successful, you will see output similar to the following:
2022/01/01 20:48:12 Starting Mejiro...
2022/01/01 20:48:12 Listening on: :8080
You can now access Mejiro by visiting http://<your-fcos-instance-ip-address>:8080 in your web browser.
In this tutorial, we went through the process of installing Mejiro on Fedora CoreOS. Mejiro makes managing PostgreSQL databases a lot easier by providing a web-based front-end.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
