# Start AzerothCore authserver + worldserver detached from the SSH session (nohup + disown).
# Stops any already-running authserver/worldserver processes first.

# Usage:
#   sudo bash scripts/start-azeroth-servers.sh
#   AZEROTH_BIN=/path/to/azeroth-server/bin bash scripts/start-azeroth-servers.sh
#
# Environment:
#   AZEROTH_BIN      — directory with authserver and worldserver (default: /root/azeroth-server/bin)
#   AZEROTH_LOG_DIR  — log directory (default: <parent of bin>/logs)
