How to Install Nginx Proxy Manager on Ubuntu 18.04

Nginx Proxy Manager is a popular open-source tool that is used to manage multiple Nginx proxy servers from a single web interface. In this article, we will guide you through the process of installing Nginx Proxy Manager on a fresh installation of Ubuntu 18.04.

Before we begin, make sure that you have a fresh installation of Ubuntu 18.04 and that Nginx is installed on your system. You will also need to be logged in as a user with sudo privileges.

Install the required dependencies

The first step is to install the required dependencies for Nginx Proxy Manager. To do this, run the following commands in the terminal:

sudo apt update
sudo apt install python3 python3-pip python3-dev libpq-dev postgresql postgresql-contrib

This will install the necessary dependencies for Nginx Proxy Manager, including Python 3, pip, PostgreSQL, and the required development libraries.

Create a new PostgreSQL user and database

Next, we need to create a new PostgreSQL user and database for Nginx Proxy Manager. To do this, log in to the PostgreSQL shell using the following command:

sudo -u postgres psql

In the PostgreSQL shell, run the following commands to create a new user and database:

CREATE USER nginxproxymanager WITH PASSWORD 'password';
CREATE DATABASE nginxproxymanager;
GRANT ALL PRIVILEGES ON DATABASE nginxproxymanager TO nginxproxymanager;

Make sure to replace “password” with the actual password that you want to use for the PostgreSQL user.

In the file, add the following configuration:

[DEFAULT]
# Database settings
sqlalchemy.url = postgresql://nginxproxymanager:password@localhost/nginxproxymanager

# Web server settings
flask.host = 127.0.0.1
flask.port = 8080

Make sure to replace "password" with the actual password that you set for the PostgreSQL user in the previous step. Save the file and exit the editor.

Initialize the database

After creating the configuration file, we need to initialize the database for Nginx Proxy Manager. To do this, run the following command in the terminal:
