How to Set Up Your Own Lineage 2 Server (L2J)

Running your own Lineage 2 server is very doable, even for a home test setup. This is the modern, high-level version of the classic guide — the tools changed, the flow did not.

What you need

• Java (JDK) — the version your chosen pack requires (older packs need Java 8; modern forks need newer).
• MySQL or MariaDB — the database engine.
• A database client — DBeaver or HeidiSQL (the modern replacements for the old Navicat everyone used).
• An L2J server pack for your chronicle — e.g. aCis (Interlude) or L2jMobius (many chronicles).
• The matching game client for players to connect with.

Steps

1. Install the JDK, then MySQL/MariaDB, then your DB client.
2. Create the two databases the pack expects (login + game) and a DB user.
3. Run the pack's database installer to build the tables.
4. Edit the config files: database credentials, and the server/external IP (use 127.0.0.1 for a local test).
5. Start the login server, then the game server.
6. Point your client to your IP and log in. Create a GM account and you are live.

Going public

• Set your external IP correctly so players outside your network can connect.
• Add geodata and protection before you open to the public.
• Then list your server on L2TopZone to attract your first players and votes.

Which pack should a beginner use?

aCis for Interlude, or L2jMobius which supports many chronicles.

How do players connect from outside my network?
