1.1. Legal and Ethical Considerations

Before setting up your server, consider the legal implications. Lineage 1 is a copyrighted game, and distributing or modifying it without permission from NCSOFT could potentially infringe on their intellectual property rights. Ensure you understand the legal risks and consider obtaining necessary permissions or using open-source alternatives. Operating System: Windows Server 2019 or Windows 10/11

Phase 1: The Hardware and Software Foundation

Before you touch a single game file, your environment must be prepared. Lineage 1 server architecture typically relies on Java or C++ depending on the source build you choose.

The Prerequisites:

Operating System: Windows Server 2019 or Windows 10/11 are most common for beginner repacks. Linux (CentOS or Ubuntu) is preferred for high-population production servers but requires advanced command-line knowledge.
Java Development Kit (JDK): Most L1J (Lineage 1 Java) emulators require Java 8 or newer. Ensure your environment variables are set correctly.
Database: MySQL (Community Edition) is the standard. You will need a management tool like Navicat or HeidiSQL to manipulate the database tables.
Hardware: A dedicated machine is ideal. You need at least 8GB RAM and a solid CPU. L1 servers are surprisingly CPU-intensive during heavy PvP due to pathfinding calculations.

Create an account

The first time you launch the client, the server will create an account automatically from any login/password not already in the database. By default, L1J uses a simple text authentication: any username/password combination creates a new account.

For security, you can disable this later (config/auth.properties → AutoCreateAccounts = false) and add accounts manually via database:

INSERT INTO accounts (login, password, lastactive, access_level)
VALUES ('myusername', 'mypassword', NOW(), 0);

Access levels: 0 = normal player, 100 = game master, 200 = administrator.

Required Software (to be installed on your server)

Operating System: Ubuntu 20.04 or 22.04 LTS (most L1J guides assume Debian/Ubuntu)
Java: OpenJDK 11 (NOT Java 17+ – many old emulators break)
Database: MariaDB 10.5 or MySQL 5.7 (not 8.0 without compatibility flags)
Web server (optional): Nginx + PHP for a register page/ranking system
Git: To clone emulator source code
