📝 Step 1: System Optimization for Gaming

Let’s optimize AlmaLinux for the best gaming performance!

# Update system packages
sudo dnf update -y

# Install essential packages
sudo dnf install -y \
    wget \
    curl \
    unzip \
    tar \
    screen \
    tmux \
    htop \
    iotop \
    net-tools \
    firewalld \
    java-17-openjdk \
    java-17-openjdk-headless \
    python3 \
    python3-pip \
    nodejs \
    npm \
    git \
    rsync \
    crontab

Gaming-Specific System Optimizations:

# Optimize kernel parameters for gaming
sudo tee -a /etc/sysctl.conf << 'EOF'
# Gaming server optimizations
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.core.netdev_max_backlog = 5000
net.ipv4.tcp_window_scaling = 1
net.ipv4.tcp_timestamps = 1
net.ipv4.tcp_sack = 1
vm.swappiness = 10
kernel.sched_migration_cost_ns = 5000000
EOF

# Apply kernel optimizations
sudo sysctl -p

# Optimize CPU scheduling for real-time gaming
echo 'kernel.sched_rt_runtime_us = 950000' | sudo tee -a /etc/sysctl.conf

Create Gaming User:

# Create dedicated user for game servers
sudo useradd -m -s /bin/bash gameserver
sudo usermod -aG wheel gameserver

# Set up gaming directories
sudo mkdir -p /opt/gameservers/{minecraft,cs2,valheim,ark,teamspeak}
sudo mkdir -p /var/log/gameservers
sudo chown -R gameserver:gameserver /opt/gameservers /var/log/gameservers

# Switch to game server user
sudo su - gameserver
cd /opt/gameservers

🔧 Step 2: Minecraft Server Setup

Minecraft is one of the most popular games to host! Let’s set up a professional server.

# Create Minecraft server directory

🛡️ Step 7: Firewall Configuration for Game Servers

Proper firewall configuration is crucial for security and functionality!

# Configure firewall for all game servers
sudo firewall-cmd --permanent --zone=public --add-port=25565/tcp   # Minecraft
sudo firewall-cmd --permanent --zone=public --add-port=25575/tcp   # Minecraft RCON

sudo firewall-cmd --permanent --zone=public --add-port=27015/tcp   # CS2
sudo firewall-cmd --permanent --zone=public --add-port=27015/udp   # CS2

sudo firewall-cmd --permanent --zone=public --add-port=2456/udp    # Valheim
sudo firewall-cmd --permanent --zone=public --add-port=2457/udp    # Valheim
sudo firewall-cmd --permanent --zone=public --add-port=2458/udp    # Valheim

sudo firewall-cmd --permanent --zone=public --add-port=7777/udp    # ARK Game
sudo firewall-cmd --permanent --zone=public --add-port=7778/tcp    # ARK Game
sudo firewall-cmd --permanent --zone=public --add-port=27015/tcp   # ARK Query

sudo firewall-cmd --permanent --zone=public --add-port=9987/udp    # TeamSpeak Voice
sudo firewall-cmd --permanent --zone=public --add-port=10011/tcp   # TeamSpeak Query
sudo firewall-cmd --permanent --zone=public --add-port=30033/tcp   # TeamSpeak File Transfer

# Reload firewall rules
sudo firewall-cmd --reload

# Verify open ports
sudo firewall-cmd --list-all

Advanced Security Rules:

# Create rate limiting for game ports
sudo firewall-cmd --permanent --new-ipset=gameserver_whitelist --type=hash:ip
sudo firewall-cmd --permanent --ipset=gameserver_whitelist --add-entry=127.0.0.1

# Add fail2ban protection for game servers
