========

1. Install Dependencies

root@host:~# apt install g++ make libc6-dev libirrlicht-dev cmake libbz2-dev libpng-dev libjpeg-dev libxxf86vm-dev libgl1-mesa-dev libsqlite3-dev libogg-dev libvorbis-dev libopenal-dev libcurl4-gnutls-dev libfreetype6-dev zlib1g-dev libgmp-dev libjsoncpp-dev

2. Make and Compile

• In one step, this will compile:
  • MultiCraft (server) https://github.com/MultiCraft/MultiCraft
  • Minetest_Game (5.4.1) https://github.com/minetest/minetest_game/releases/tag/5.4.1

user@host:~$ wget https://github.com/MultiCraft/MultiCraft/archive/main.tar.gz && \
tar -xzf main.tar.gz && rm main.tar.gz && \
cd MultiCraft-main/games/ && \
wget https://github.com/minetest/minetest_game/archive/refs/tags/5.4.1.tar.gz && \
tar -xzf 5.4.1.tar.gz && rm 5.4.1.tar.gz && \
mv minetest_game-5.4.1 minetest_game && cd .. && \
cmake . -DRUN_IN_PLACE=TRUE -DBUILD_CLIENT=FALSE -DBUILD_SERVER=TRUE -DENABLE_POSTGRESQL=ON -DPostgreSQL_TYPE_INCLUDE_DIR=/usr/include/postgresql/15/server/libpq && \
make -j$(nproc)

When compiling is complete, the multicraftserver binary can be found in ~/MultiCraft-main/bin/

3. world.mt

MultiCraft only supports 'file' type mod_storage

• Configure ~/MultiCraft-main/worlds/yourworld/world.mt file to include postgresql backend(s)
• Each backend type (map, players, auth, mapserver) requires it's own database
• Make sure to change the username, password, and dbname to your own setting! For Socket Connection

# map
backend = postgresql
pgsql_connection = postgresql:///mapdb?host=/var/run/postgresql&user=psqluser&password=securepassword&dbname=mapdb
# auth
auth_backend = postgresql
pgsql_auth_connection = postgresql:///authdb?host=/var/run/postgresql&user=psqluser&password=securepassword&dbname=authdb
# player
player_backend = postgresql
pgsql_player_connection = postgresql:///playerdb?host=/var/run/postgresql&user=psqluser&password=securepassword&dbname=playerdb
# mapserver
pgsql_mapserver_connection = postgresql:///mapserverdb?host=/var/run/postgresql&user=psqluser&password=securepassword&dbname=mapserverdb

For IP connection

# map
backend = postgresql
pgsql_connection = host=127.0.0.1 port=5432 user=psqluser password=securepassword dbname=mapdb
# auth
auth_backend = postgresql
pgsql_auth_connection = host=127.0.0.1 port=5432 user=psqluser password=securepassword dbname=authdb
# player
player_backend = postgresql
pgsql_player_connection = host=127.0.0.1 port=5432 user=psqluser password=securepassword dbname=playerdb
# mapserver
pgsql_mapserver_connection = host=127.0.0.1 port=5432 user=psqluser password=securepassword dbname=mapserverdb

Mapserver is optional, and not yet covered by this tutorial. Source can be found here: https://github.com/minetest-mapserver/mapserver

4. minetest.conf

• Configure ~/MultiCraft-main/minetest.conf with the settings you want, here are a few to get started

## Server
name = FullPrivsADMIN
server_announce = false
server_address = yourdomain.com 
server_name = AFK Server
port = 30000
max_users = 64
serverlist_url = servers.multicraft.world
announce_mt = true

## Game
default_game = minetest
static_spawnpoint = 0,12,0
time_speed = 50
creative_mode = false
enable_damage = true
enable_pvp = true
default_privs = shout, interact
give_initial_stuff = true
initial_stuff = default:torch 99,default:apple 99,default:pick_steel,default:axe_steel

## Logging
profiler.load = true
debug_log_level = action
debug_log_size_max = 5000
log_mod_memory_usage_on_load = true
log_mods = true
enable_mapgen_debug_info = true

## Security
disallow_empty_password = true
disable_anticheat = false
secure.enable_security = true
csm_restriction_flags = 63
csm_restriction_noderange = 1
enable_client_modding = false

A complete list of config settings can be found here: https://github.com/MultiCraft/MultiCraft/blob/63cf8adad14318b25ccfe5a7557ac7870ceed753/builtin/settingtypes.txt#L1020

4. Run Server

user@host:~/MultiCraft-main$ ./bin/multicraftserver --world ./worlds/yourworld --config ./minetest.conf --gameid minetest_game

You now have a functional MultiCraft server.
