- PBS Pro Server Configuration – A Comprehensive Guide
This article provides a detailed overview of the PBS Pro server configuration, aimed at newcomers to our system. The PBS Pro is a dedicated server solution optimized for running demanding MediaWiki installations, particularly those with high traffic or complex extensions. This guide covers the hardware specifications, software stack, and crucial configuration settings.
Overview
The PBS Pro server is designed for performance and reliability. It utilizes high-end components and a carefully tuned software stack to ensure a smooth and responsive experience for all users. It’s ideal for wikis with a large number of pages, frequent edits, and a substantial user base. Understanding the underlying architecture is key to maximizing its potential and troubleshooting any issues that may arise. This setup differs significantly from a standard LAMP stack configuration and is intended for experienced administrators or those willing to learn. Understanding Server administration is highly recommended.
Hardware Specifications
The PBS Pro server boasts significant hardware resources. Below is a detailed breakdown of the specifications:
| Component | Specification |
|---|---|
| Processor | Dual Intel Xeon Gold 6248R (24 cores / 48 threads per CPU) |
| RAM | 256 GB DDR4 ECC Registered RAM |
| Storage (OS/Software) | 2 x 480GB NVMe SSD (RAID 1) |
| Storage (Wiki Data) | 8 x 4TB SAS HDD (RAID 6) |
| Network Interface | Dual 10 Gigabit Ethernet |
| Power Supply | Redundant 1600W Platinum Power Supplies |
These specifications ensure ample processing power, memory, and storage capacity to handle even the most demanding wiki environments. The use of RAID configurations provides data redundancy and improves read/write performance. Refer to the RAID article for more details.
Software Stack
The PBS Pro server utilizes a specific software stack optimized for MediaWiki performance. This includes the operating system, web server, database server, and PHP version.
| Software | Version |
|---|---|
| Operating System | Ubuntu Server 22.04 LTS |
| Web Server | Apache 2.4 |
| Database Server | MariaDB 10.6 |
| PHP | PHP 8.2 (with FPM) |
| PHP Extensions | intl, mbstring, json, pdo_mysql, xml, zip, gd, curl |
The choice of Ubuntu Server 22.04 LTS provides a stable and well-supported platform. Apache 2.4, configured with PHP-FPM, delivers excellent performance. MariaDB 10.6 is a robust and scalable database solution. The specified PHP extensions are essential for MediaWiki functionality. For more information on these components, see Apache configuration, MariaDB setup, and PHP extensions. Proper configuration of Firewall rules is also crucial.
Key Configuration Settings
Several key configuration settings are crucial for optimal PBS Pro performance. These settings are adjusted during the initial server setup and may require periodic review and adjustment based on usage patterns.
| Setting | Value | Description |
|---|---|---|
| `php.ini` - `memory_limit` | 8G | Sets the maximum amount of memory a script may consume. |
| `php.ini` - `max_execution_time` | 300 | Sets the maximum time in seconds a script is allowed to run. |
| Apache - `MaxRequestWorkers` | 256 | Controls the maximum number of concurrent requests Apache can handle. |
| MariaDB - `innodb_buffer_pool_size` | 128G | Allocates memory to the InnoDB buffer pool for caching data and indexes. |
| MariaDB - `query_cache_size` | 512M | Allocates memory for caching query results. |
These settings are carefully chosen to balance performance and resource utilization. Monitoring server resources using tools like System monitoring is essential for identifying potential bottlenecks and adjusting these settings accordingly. Regular Database maintenance is also vital. Understanding Caching strategies can drastically improve performance.
Security Considerations
Security is paramount. The PBS Pro server is configured with several security measures by default, but ongoing attention is required.
- **Firewall:** A robust firewall is enabled to restrict access to necessary ports only.
- **Regular Updates:** The operating system and software stack are regularly updated with the latest security patches.
- **SSL/TLS:** All traffic is encrypted using SSL/TLS.
- **User Permissions:** Strict user permissions are enforced to limit access to sensitive files and directories.
- **Intrusion Detection:** An intrusion detection system (IDS) is implemented to monitor for malicious activity. See Security best practices for more details.
Monitoring and Maintenance
Continuous monitoring and regular maintenance are essential for ensuring the long-term health and performance of the PBS Pro server. This includes:
- **Resource Monitoring:** Tracking CPU usage, memory consumption, disk I/O, and network traffic.
- **Log Analysis:** Regularly reviewing server logs for errors and warnings.
- **Database Backups:** Performing regular database backups to protect against data loss.
- **Software Updates:** Applying the latest software updates and security patches. Consult the Backup strategies article.
