n8n is a modern workflow automation tool that integrates more than 300 different services and platforms. With its help, you can create complex automation scenarios without needing to write code — simply connecting nodes with visual links.

Self-hosting n8n on your own VPS gives maximum control over your automated processes. In this guide, we'll cover installing n8n using Docker — the most practical and scalable deployment method.

System Requirements

For successful installation of n8n, you'll need:

• VPS server with Linux (Ubuntu 22.04 or later is recommended)
• Account with administrative privileges (sudo)
• Docker and Docker Compose
• Minimum 1 GB RAM (2 GB or more recommended)
• Minimum 5-10 GB free disk space (20 GB or more recommended for active use)

Environment Preparation: Installing Docker

Start by connecting to the server via SSH and run the following commands to install Docker:

sudo apt update
sudo apt install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
sudo apt install -y docker-ce docker-compose

Verify the correct installation by checking versions:

docker --version
docker-compose --version

To simplify work, add your user to the docker group:

sudo usermod -aG docker $USER

Quick Installation Using Docker

Creating Persistent Storage

First, create a Docker volume to save n8n settings and data:

docker volume create n8n_data

Running n8n

Execute the command to start the n8n container:

docker run -it --rm \
--name n8n \
-p 5678:5678 \
-v n8n_data:/home/node/.n8n \
docker.n8n.io/n8nio/n8n

After startup, n8n will be available through the browser at:

http://<your_VPS_IP>:5678

PostgreSQL Integration (Extended Configuration — Optional)

n8n initially works with the lightweight SQLite database, which is perfect for development and small projects. However, SQLite has performance limitations under intensive use and doesn't support concurrent operation of multiple processes.

For stable operation in production environment and ensuring scalability, you should switch to PostgreSQL — a professional relational DBMS capable of handling large data volumes and multiple connections.

PostgreSQL Setup

The first step is to deploy PostgreSQL. You can choose one of the following options:

• Installation on the same server.
• Using cloud services (ElephantSQL, AWS RDS, Google Cloud SQL).
• Deployment on a separate server.

Deploying PostgreSQL via Docker

For quick creation of a PostgreSQL instance, use the following command:

docker run --name postgres \
-e POSTGRES_USER=n8n_user \
-e POSTGRES_PASSWORD=supersecret \
-e POSTGRES_DB=n8n \
-p 5432:5432 \
-d postgres

Container parameters:

• n8n_user — database user (you can choose any name),
• supersecret — access password (use a strong password),
• n8n — name of the database to be created.

Connecting n8n to PostgreSQL

After starting PostgreSQL, configure n8n to work with the new database:

docker run -it --rm \
--name n8n \
-p 5678:5678 \
-e DB_TYPE=postgresdb \
-e DB_POSTGRESDB_DATABASE=n8n \
-e DB_POSTGRESDB_HOST=localhost \
-e DB_POSTGRESDB_PORT=5432 \
-e DB_POSTGRESDB_USER=n8n_user \
-e DB_POSTGRESDB_PASSWORD=supersecret \
-v n8n_data:/home/node/.n8n \
docker.n8n.io/n8nio/n8n

Environment variables description:

• DB_TYPE=postgresdb — activates PostgreSQL driver,
• DB_POSTGRESDB_DATABASE=n8n — target database name,
• DB_POSTGRESDB_HOST=localhost — database server host (replace with actual IP for remote deployment),
• DB_POSTGRESDB_PORT=5432 — PostgreSQL connection port,
• DB_POSTGRESDB_USER=n8n_user — user credentials,
• DB_POSTGRESDB_PASSWORD=supersecret — authentication password.

Security Recommendations

Consider the following points when configuring:

• Create unique database and user names.
• Use strong passwords to protect data.
• Verify network accessibility between n8n and PostgreSQL containers.
• When using external PostgreSQL, configure the firewall to allow incoming connections from the n8n server's IP address.

Installation via Docker Compose (Preferred Method)

Docker Compose simplifies container and configuration management. This approach is recommended for permanent operation.

Creating Configuration File

Create a Docker Compose configuration file in the nano text editor by entering the command in terminal:

nano docker-compose.yml

Insert the following configuration into the opened editor:

version: '3'

services:
  n8n:
    image: docker.n8n.io/n8nio/n8n
    restart: always
    ports:
      - "5678:5678"
    environment:
      - GENERIC_TIMEZONE=Europe/Berlin
    volumes:
      - n8n_data:/home/node/.n8n

volumes:
  n8n_data:

Save the file with the keyboard shortcut:

• Ctrl + O (save)
• Enter (confirm)
• Ctrl + X (exit editor)

Managing n8n

Start n8n in background mode:

docker compose up -d

Stop n8n:

docker compose down

Updating n8n to the Latest Version

To update n8n, execute the commands sequentially:

docker compose pull
docker compose down
docker compose up -d

Tunnel Mode: Working with External Webhooks

Purpose of Tunnel

Tunnel mode creates a temporary public HTTPS address for your local server, which is necessary for testing incoming webhooks from external services (Telegram, Stripe, Zapier, etc.), in case you don't have a domain and HTTPS.

Application

This mode is perfect for:

• Debugging webhook integrations
• Testing automation with external services
• Temporary server publication without SSL configuration

Activating Tunnel

docker run -it --rm \
--name n8n \
-p 5678:5678 \
-v n8n_data:/home/node/.n8n \
docker.n8n.io/n8nio/n8n \
start --tunnel

Frequently Asked Questions

This tutorial will teach you how to install a LAMP stack on a virtual server.

LAMP is a suite of software including:

• Linux;
• Apache;
• MySQL;
• PHP.

This will allow you to run your own website after installing it.

We are going to use a virtual server, HT-VPS-5 tariff, 16 GB RAM and 160 GB SSD-drive. However, for the majority of basic tasks (blog, business card site) and projects that are not very demanding, a simpler HT-VPS-1 configuration will be fine. The operating system we use is the Linux distribution Ubuntu 20.04.

To begin with, allow us to have a look at the basics of running a website. Each site requires different components for its functionality. Typically, these include a web server, support for the programming language that the site is written in, and database support. Here we will guide you how to install Apache web server, PHP language support and MySQL database support.

SSH SETUP

We are going to do all operations using the prompt with the SSH protocol. You should know your IP address, username and password. You will receive this data for connection in an email when you order a virtual server.

Open a command prompt (terminal) on your local computer and input the command to connect.

shh root@XXX.XXX.XXX.XXX

Enter the address of your server instead of XXX.XXX.XXX.XXX.

If this is the first time you connect, you may see this message:

The authenticity of host 'XXX.XXX.XXX.XXX (XXX.XXX.XXX.XXX)' can't be established. RSA key fingerprint is SHA256:YaaqERsh9oMs/Qa5nlMJLlb4ewlJDGLaDGsuOcDzOs8. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Please just press 'yes' or the letter 'y', you will be asked to enter your password

Warning: Permanently added 'XXX.XXX.XXX.XXX' (RSA) to the list of known hosts. root@ip_XXX.XXX.XXX.XXX's password:

Type in the password and press 'Enter'.

When you connect to the server, you get to the command prompt on the server itself, i.e. in the system installed on the server.

Before you install any components, we recommend you upgrade your system to the latest up-to-date version.

Run the commands sequentially:

apt update

apt upgrade

An update of the system will start.

The next step is to reboot the server, you can do this using the reboot command.

Before proceeding to the LAMP installation, you need to perform the initial configuration of the server.

Right now you are logged in as root, which is insecure, so you should create a non-privileged user.

Let's run the adduser [username] command to do this, for instance:

adduser host-telecom

Next, enter the password for this user twice.

After that you will be asked to enter some user data (full name, phone number, etc.), but you don't have to enter all of this, you can just leave the fields blank by pressing 'enter' each time.

Now, you created a new user, although he doesn't have administrator rights. To give it root privileges, you need to add it to the sudo group.

Execute the command:

usermod -aG sudo host-telecom

UFW FIREWALL SETUP

To improve server security, we recommend to use the popular and simple to customize UFW firewall. Various applications can register their own profiles for UFW, meaning ready-made sets of security settings that you can activate. Let's output the list of current profiles with the command:

sudo ufw app list

Available applications: OpenSSH

The profile of the OpenSSH service is now available in our case, which allows us to connect to the server via SSH.

Activate this service using the command:

ufw allow OpenSSH

Rules updated Rules updated (v6)

Next, activate the firewall by command:

ufw enable

You will be warned that the current connection may be interrupted:

Command may disrupt existing ssh connections. Proceed with operation (y|n)?

But because you have enabled OpenSSH, don't be concerned and type 'y' and press 'Enter'.

Firewall is active and enabled on system startup

To check the status of the firewall run the command:

ufw status

You can see that it is active and the OpenSSH profile is also active:

Status: active To Action From -- ------ ---- OpenSSH ALLOW Anywhere OpenSSH (v6) ALLOW Anywhere (v6)

You allowed only SSH connections, and the firewall now blocks all other connections. Later, you will allow HTTP connections to open a website.

Here's a very important point: you need to connect using SSH, not as root, but as the host-telecom user you just created.

For this purpose, don't close your current SSH connection to root for now, but instead open a new terminal window and connect in it, just in case you might suddenly run into problems and be able to fix them.

In the new terminal window, run the command:

ssh host-telecom@XXX.XXX.XXX.XXX

Enter the password for the host-telecom user.

If all is successful, you will be prompted to enter commands, but you will be working under the host-telecom user, and all administrative commands will have to be executed via sudo, i.e. you will enter 'sudo' before each command.

You can close the SSH session with the root user by typing the 'exit' command.

APACHE WEB SERVER SETUP

To install the Apache web server, run the command:

sudo apt install apache2

Make changes to the firewall before testing the Apache web server.

Check the list of profiles:

sudo ufw app list

You will find that apart from OpenSSH, 3 new Apache profiles are also added. Each profile contains a set of settings:

• Apache — opens port 80, used by the http protocol;
• Apache Full — opens ports 80 and 443, used by http and https protocols;
• Apache Secure — opens port 443 only.

You need to apply Apache Full to allow both http and https traffic.

Run the command to activate the profile:

sudo ufw allow in "Apache Full"

Rule added Rule added (v6)

Once this is done, you can test how Apache works and open the default website.

For this purpose, open your browser and enter the IP address of the server. The following information page will appear:

Actually it is already a running website with a single HTML page.

MYSQL DATABASE SUPPORT SETUP

To install MySQL database support, run the command:

sudo apt install mysql-server

Once the installation is complete, we recommend running a special script that helps you set various security settings. Run the command to do this:

sudo mysql_secure_installation

Further you need to answer a few questions. The first is to enable the VALIDATE PASSWORD plugin, used to prevent simple passwords from being used when setting MySQL database passwords. To enable it, type 'y' and press 'enter'.

The next step asks you to set the level of password validation:

There are three levels of password validation policy: LOW Length >= 8 MEDIUM Length >= 8, numeric, mixed case, and special characters STRONG Length >= 8, numeric, mixed case, special characters and dictionary file Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG:

Choose medium: enter 1 and press 'enter'.

Then enter a strong password and confirm it.

You can answer all subsequent questions with 'y' and then press 'enter':

• request to remove an anonymous user,
• request to disable remote authorization of the root user,
• deleting the test database.

Once complete, you will be prompted to activate the settings and customizations you have made.

You will get a message as a result:

Success. All done!

PHP LANGUAGE SUPPORT SETUP

Further, you should install support for the PHP language. To do this, you need to install three packages:

• PHP
• libapache2-mod-php — a module that allows you to process PHP files,
• php-mysql — allows PHP to communicate with MySQL.

sudo apt install php libapache2-mod-php php-mysql

The LAMP installation is now complete.

However, before you can launch your site, you have to create a virtual host for it. Create a directory for your site and make the settings for your host.

Run the command:

sudo mkdir /var/www/mysite

Specify the domain of your site instead of mysite.

You created the directory using sudo, i.e. as root. Change the permissions and group for this directory to be under your host-telecom user.

sudo chown -R $USER:$USER /var/www/mysite

Then, you should create a configuration file for your virtual host. Configuration files are stored in the /etc/apache2/sites-available directory. Open the console text editor nano and create a configuration file. Run the command:

sudo nano /etc/apache2/sites-available/mysite.conf

Paste the following code:

<VirtualHost *:80> ServerName XXX.XXX.XXX.XXX ServerAlias XXX.XXX.XXX.XXX ServerAdmin host-telecom@localhost DocumentRoot /var/www/mysite ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>

Exit the nano editor by pressing Ctrl + X, and enter 'yes' to save the file..

To get your virtual host activated by the web server, run the command:

sudo a2ensite mysite

You need to restart the server to allow the changes to take effect. Run the command:

sudo systemctl reload apache2

Create a test page in your directory where your site files should be located. Open the nano text editor again:

nano /var/www/mysite/index.php

And add the following code in it:

<?php phpinfo();

This is a PHP function that displays detailed information about the current php configuration. Enter the IP address of your server into the address bar of your browser and you will see that you get a page with PHP configuration information.

We've reviewed the basic steps of setting up Apache, PHP, MySQL and learned how to create virtual hosts. Now you can install almost any CMS and launch your online business or blog.

After the installation and configuration of the caching DNS server, if the server can be accessed at an external (white) address, you should check that the server responds only to requests from trusted hosts (clients). If the server responds to requests from all hosts, this server is called DNS Open Resolver.

The risk exists that DNS Open Resolver can be exploited by attackers to perform various types of attacks:

• Loading the server with random DNS requests, blocking the channel with traffic. This can cause a denial of service (DoS) and make the DNS service inaccessible to other users.
• Sending special requests to a server with a fake source IP address in order to organize an attack on a third host that involves your server. DNS Open Resolver will send responses to this spoofed address, which can lead to a high volume of network traffic aimed at the victim of the attack. Such an attack is called DNS Amplification.
• Replace responses to your server with false data that will get into the cache (Cache Poisoning). When a client computer accesses a DNS server that is compromised this way, it may obtain false or malicious IP addresses for domain names.

On receiving a recursive request, the server either returns an answer to the request or an error message. The server performs all data searching and querying of other servers. In case of receiving an iterative request, the server can return the address of another server rather than the answer, and then the client will forward this request to the specified server.

How to check if a server is open

You can check if your server is open to recursive requests at https://openresolver.com/.

Or with commands that perform requests to DNS:

dig +short @XXX.XXX.XXX.XXX mysite.ru

host mysite.ru XXX.XXX.XXX.XXX

nslookup mysite.ru XXX.XXX.XXX.XXX

As XXX.XXX.XXX.XXX enter the IP address of the server to be checked. The example name is mysite.ru, you can check any.

If the request gives an IP address when requested from any host, then your server is DNS Open Resolver.

How to turn off or limit access to only authorized hosts/networks

1. Limit access to the server port (udp/53) on the network perimeter, or locally on the DNS server itself.
2. If you want the server to be responsible for only one or a few specific zones, you can turn off recursive queries by adding the “recursion no;” option to the named.conf configuration file (named.conf.local or other, depending on your settings).
3. Enable recursive requests for trusted networks/hosts only, example: “allow-recursion { localhost; 10.16.0.0.0/16; };” (10.16.0.0.0/16 — replace with trusted addresses).

In this guide, we will review the ispmanager site and server control panel in detail and tell you about its main advantages and versions.

What does ispmanager do

The ispmanager panel helps you to install and manage web services. It deploys all the required software to maintain websites, mail, and databases. It lets users run projects in a ready-to-use web environment and then manage them in a graphical interface, without the need for a console.

The ispmanager panel is helpful for web developers, system administrators, and site managers. The panel significantly simplifies server administration, which means it can be used not only by skilled professionals but also by newcomers.

The latest version of the panel is ispmanager 6. It has an improved interface, a more proactive bug-fixing system, system monitoring, advanced tools for developers, and support for major CMSes.

The key features of the ispmanager panel

Web server support and management. You can install and configure web servers such as Apache, Nginx, and OpenLite Speed from the panel. There is no problem with further administration.

Mail domains creation and mailbox management. You can use the panel to create a mail domain and mailbox, adjust rules and restrictions, use anti-spam and anti-virus protection, and connect Roundcube web interface. It is possible to get a configuration file for mail clients.

Database support and management. MySQL/MariaDB, PostgreSQL, Percona Server.

Website creation and management. The ispmanager panel includes tools for simple work with websites at all stages: from installing CMS to adding content.

File management. The graphical file manager supports downloading large data volumes without connection loss. It also supports popular FTP servers.

Programming languages support. It is possible to add Python and Perl straight from the panel, without further configuring the repositories. You can choose the PHP interpreter version and mode for a separate site. It supports Node.js handler and PHP Composer.

Server and site protection. It includes tools for server backup, mail protection, firewall, response to DDoS attacks, and high-quality anti-virus Dr.Web to keep your system protected.

Dark and light theme. Ispmanager follows all modern design trends and takes care of user experience. Dark theme is a smart solution, which makes it more convenient to work in a dark place.

Which ispmanager version will be the one to choose?

Today, four versions (licenses) of the ispmanager panel exist. There are three versions — lite, pro, and host — which are mostly used for deploying and administering sites on VPS or dedicated servers. Licenses vary in the number of domains that you can manage. However, if you are an internet hosting provider and would like to offer a panel to your customers, the business version is the right option for you. Let's look more closely at the features and differences.

Ispmanager lite is ideal for freelancers and web studios that have a small number of projects — no more than 10 domains. However, a lot of team members can work with the panel: the total number of user accounts is unlimited. The version provides all the necessary tools for a developer: it allows you to configure web servers, make websites, and add extra modules.

Ispmanager pro has the same features as the lite version but also supports a maximum of 50 domains, so it is sufficient for a larger number of projects. Additionally, it has a complete module to work with Docker technology.

Ispmanager host has the same functionality as the pro version, but without limiting the number of domains, which means that it is suitable for large web studios.

Ispmanager business

Ispmanager business significantly differs from other versions and is designed for service providers. The business version supports shared hosting:

• manages a cluster of servers;
• allows setting up reselling;
• allows limiting RAM, and CPU for users, to ensure that "neighbors" in hosting do not disturb each other.

We've put together the main differences between the versions in a useful table to help you choose the best version for your needs.

Lite	Pro	Host	Business
For web developers and site administrators. Can be purchased from a provider or installed directly on VPS, dedicated servers			For providers and resellers
Up to 10 domains	Up to 50 domains	Unlimited number of domains	Unlimited number of domains
For one or more projects	For the average number of projects	To support a large number of websites	To start a business with ispmanager

The version of ispmanager to choose depends on your needs and the number of projects you are going to manage. If you want to build and manage websites, the lite, pro, or host licenses are sufficient. If you prefer to run your own hosting and reselling service, choose business. If you order our servers, either VPS or dedicated, then you can pick any version of ispmanager that meets your specific needs.
