<ul style="color: #fef3c7; line-height: 1.8;">
|
||
<li>Only open ports that are necessary for the game server to function</li>
|
||
<li>Consider using non-standard ports to reduce automated attacks</li>

<li>If using cloud hosting, configure security groups properly</li>
|
||
<li>Monitor connection attempts and unusual traffic patterns</li>

<h2 id="troubleshooting">🔧 Troubleshooting</h2>
|
||
|
||
<h3>Server Won't Start</h3>
|
||
|
||
<h4>Server not listed or query fails</h4>
|
||
<p>Open 27015/udp and 27015/tcp; check -ip/-port; ensure sv_lan 0; verify external firewall/NAT.</p>
|
||
|
||
<h4>Workshop maps not downloading</h4>
|
||
<p>Ensure -authkey is present; server has internet access; use +host_workshop_collection and +workshop_start_map or fall back to FastDL.</p>
|
||
|
||
<h3>Connection Issues</h3>
|
||
|
||
<h4>Can't Connect to Server</h4>
|
||
<ol>
|
||
<li><strong>Verify server is running:</strong> <code>ps aux | grep server</code></li>
|
||
<li><strong>Check port is listening:</strong> <code>netstat -an | grep [PORT]</code></li>
|
||
<li><strong>Verify firewall rules</strong> (see Ports section above)</li>
|
||
<li><strong>Check server IP:</strong> Use external IP, not localhost</li>
|
||
<li><strong>Router/NAT:</strong> Ensure port forwarding is configured</li>
|
||
</ol>
|
||
|
||
<h4>High Latency/Lag</h4>
|
||
<ul>
|
||
<li>Check server resource usage (CPU, RAM, disk I/O)</li>
|
||
<li>Verify network bandwidth is adequate</li>
|
||
<li>Consider server location relative to players</li>
|
||
<li>Check for background processes consuming resources</li>
|
||
</ul>
|
||
|
||
<h3>Performance Issues</h3>
|
||
|
||
<h4>Server Lag</h4>
|
||
<ol>
|
||
<li><strong>Monitor resources:</strong> Use <code>htop</code> or <code>top</code></li>
|
||
<li><strong>Check disk I/O:</strong> Use <code>iotop</code></li>
|
||
<li><strong>Review server logs</strong> for errors or warnings</li>
|
||
<li><strong>Reduce player count</strong> or increase server resources</li>
|
||
<li><strong>Optimize configuration</strong> based on server capacity</li>
|
||
</ol>
|
||
|
||
<h4>Memory Leaks</h4>
|
||
<pre><code># Monitor memory usage
|
||
free -h
|
||
top -p $(pgrep -f server)
|
||
|
||
# Restart server regularly via cron if needed
|
||
0 4 * * * /home/gameserver/restart.sh
|
||
</code></pre>
|
||
|
||
<h2 id="performance">Performance Optimization</h2>
|
||
|
||
<h3>Server Tuning</h3>
|
||
<ul>
|
||
<li><strong>CPU:</strong> Ensure adequate CPU allocation; most game servers are single-threaded</li>
|
||
<li><strong>RAM:</strong> Allocate sufficient memory; monitor usage and adjust as needed</li>
|
||
<li><strong>Disk:</strong> Use SSD storage for better I/O performance</li>
|
||
<li><strong>Network:</strong> Ensure stable, low-latency connection</li>
|
||
</ul>
|
||
|
||
<h3>Operating System Optimization</h3>
|
||
<pre><code># Increase file descriptor limits
|
||
echo "* soft nofile 65536" >> /etc/security/limits.conf
|
||
echo "* hard nofile 65536" >> /etc/security/limits.conf
|
||
|
||
# Network tuning
|
||
sysctl -w net.core.rmem_max=16777216

sysctl -w net.core.wmem_max=16777216
|

|
||
sysctl -w net.ipv4.tcp_wmem="4096 87380 16777216"
|
||
</code></pre>
|
||
|
||
<h3>Monitoring</h3>
|
||
<p>Set up monitoring to track server health:</p>
|
||
<ul>
|
||
<li>CPU and memory usage</li>
|
||
<li>Network traffic and latency</li>
|
||
<li>Player count and activity</li>
|
||
<li>Error rates and crash logs</li>
|
||
</ul>
|
||
|
||
<h3>Backup Strategy</h3>
|
||
<pre><code>#!/bin/bash
|
||
# backup.sh - Run via cron
|
||
DATE=$(date +%Y%m%d_%H%M%S)
|
||
BACKUP_DIR="/backups/gameserver"
|
||
SERVER_DIR="/home/gameserver/server"
|
||
|
||
# Create backup
|
||
tar -czf $BACKUP_DIR/backup_$DATE.tar.gz -C $SERVER_DIR .
|
||
|
||
# Keep only last 7 days
|
||
find $BACKUP_DIR -name "backup_*.tar.gz" -mtime +7 -delete
