Since this commit we introduced a new and automatic way of installing and keeping the databases up-to-date.

This is described in more detail in the following instructions.

Downloading the

database

Download the latest database compilation from TrinityCore Downloads.

(you may need to click on Next at page footer to see the proper TDB files).

• Note that there are different database compilations available for different branches of TrinityCore, for example 3.3.5 and master.

Search the database for the branch you are trying to use, for 3.3.5a it will be named TDB 335 and a 5 digits value, click on Assets and you should see a link to download TDB_full_*.7z.

For master branch search for the higher numbered version non TDB 335.

• You want to download the file in .7z format - that is the database download and the others are not
• The file is in .7z format, so you will need an archive program like 7zip to unpack it.

Installing The Trinity Databases

Creating the Trinity databases in MySQL

To create the MySQL databases needed by Trinity, you need to execute one of the following MySQL queries with your mysql client:

• For 3.3.x:
  • https://github.com/TrinityCore/TrinityCore/blob/3.3.5/sql/create/create_mysql.sql
• For master:
  • https://github.com/TrinityCore/TrinityCore/blob/master/sql/create/create_mysql.sql

You can perform this with a MySQL client or with the MySQL command-line interface (CLI).

You would need to use one MySQL root account with your MySQL client or with MySQL CLI before starting core to run one of those files (use MySQL root only to import one of those files, never run core as root or administrator).

TIP: edit those 2 files and change default password to something else for increased security (remember to edit conf files to use new password).

By default Trinity needs three databases to run at 3.3.5 branch and four for master with the following names - Auth, Characters, and World:

World and hotfixes (the last one master only), if you already have those databases on use you will need to edit create_mysql.sql file and config files to avoid data loss or errors on setup of database to use different database names:

• auth - holds account data - usernames, passwords, GM access, realm information, etc.
• characters - holds character data - created characters, inventory, bank items, auction house, tickets, etc.
• world - holds game-experience content such as NPCs, quests, objects, etc
• hotfixes (master only) - holds fixes not already added to the core or other official databases.

Populating the MySQL Trinity databases

(if you are running 6.x - hotfixes as well)

The following steps are done using the database management program you installed in Step1: Requirements (ex. HeidiSQL or SQLYog):

• In HeidiSQL, click on the database you want to use in order to "select" it, then click Tools > Load SQL File... > (select the file) > Run file(s) directly.
• In SQLYog, click on the database you want to use in order to "select" it, then click Database > Import > Execute SQL Script.
• On mysql cli you must use mysql --default-character-set=utf8 to avoid import failures
  • WE STRONGLY RECOMMEND TO USE THIS METHOD over the SQLYog or HeidiSQL, it is by far the fastest method to import TDB and it's needed updates.

1. Create the three databases by importing ...\sql\create\create_mysql.sql. You now have three databases - auth, characters, and world. You may need to refresh your program in order to see the new databases.
2. Click on the "auth" database and import the auth database structure by importing ...\sql\base\auth_database.sql.
3. Click on the "characters" database and import the characters database structure by importing ...\sql\base\character_database.sql.
4. Click on the "world" database and import the world database structure by extracting and importing the "TDB_full_*.sql" file you downloaded from the Database download section.
5. Click on the "world" database and import any *.sql file available in your ...\sql\updates\world folder THIS IS MANDATORY or your core can fail to start.
6. NOTICE WE NEVER IMPORT sql\updates\auth or sql\updates\character files on fresh installation, those files are for update trinitycore not for fresh install.
7. NEVER ENABLE CONTINUE ON ERROR ON YOUR SQL CLIENT

From the unpacked 7z folder copy the SQL files that start with "TDB_world_" and "TDB_hotfixes_" (hotfixes named file is master branch only) to the directory where your worldserver binary (worldserver on linux or mac, worldserver.exe on windows) is (DON'T RENAME THOSE FILES OR AUTOMATIC SETUP WILL FAIL).

NOTICE: you don't need to import any databases, only the file creating users. If you have plans to import databases manually you need to disable autoupdater on config files.

If you have plans to change default mysql usernames and passwords make sure you have set valid database login information and the table names you want to use in the same config files (authserver (3.3.5a only)/bnetserver (master branch only)/worldserver.conf) under "CONNECTIONS AND DIRECTORIES".

• Notice that the databases are not created yet. The names you set in the config will be used for the created databases.
  

Start worldserver and press enter when it asks if you want to create databases.

After the server has created the databases it will look for maps and vmaps, if not found it will exit.

Keeping the DB up to date

Both core and DB fixes will be committed to the TrinityCore repository, which you may also view in Git Extensions by following the "Fetch" instructions in Keeping the Source Up-to-Date Windows / Linux. Pending fixes can be found on our tracker with data from the developers and contributors.

As mentioned earlier, it is recommended to stay on the same revision as the TDB_full database (Beginner).

SELECT * FROM `version`;

• Beginners
  • Extract the TDB_FULL.sql file from the archive and import it into your world database.
  • If they exist, also import the characters_ and auth_ .sql files into their respective databases.
  • Once this is finished and you have already compiled your source, you may run the worldserver binary to load your server. The revision update is complete.

Note: It is at this point that most user errors occur. If your worldserver.exe closes abruptly, make sure that your core's version matches your database version. Check that the `version` table in your world database matches the commit hash listed beside the archive you downloaded at TrinityCore Downloads.

• Advanced Users

If you update your source beyond a monthly revision, you will likely have additional updates in the ...\sql\updates folder. The folders within show which database they need to be imported to. For example, the "world" folder has all of the files that need to be imported to your world DB.

File naming conventions follow simple and consistent rules:

yyyy_mm_dd_id_world_tablename.sql -> World DB

yyyy_mm_dd_id_character_tablename.sql -> Characters DB

yyyy_mm_dd_id_auth_tablename.sql -> Auth DB

Note: The incremental daily id starts at 00, with 00 needing to be imported first, then 01, then 02, etc.

It is imperative to know the date of your previous revision when updating in order to import all of the updates from that revision to your current one.

• Browse into your ...\sql\updates\world folder and import all*_world_*.sql files into your world DB that have a date later than your previous revision.
• Do the same above step for the characters and auth folders, if they exist. If these folders don't exist, there have not been any characters or auth database updates.

•  Trouble with your TrinityCore Install / Readme 1st / FAQs

Thanks to the automatic DB updater the single step you have to do, is to fetch a new revision (Keeping the Source Up-to-Date Windows / Linux) and the appropriate updates will we applied at server startup.
