In-depth study of the underlying development principles of PHP: server deployment and performance monitoring

With the rapid development of the Internet, PHP, as an efficient and convenient server-side scripting language, has been It is widely used in the field of web development. As a PHP developer, understanding the underlying development principles of PHP, especially knowledge of server deployment and performance monitoring, is crucial to improving the performance and stability of applications.

1. Server deployment

1. Hardware environment selection

Before deploying the server, you must first select the appropriate hardware environment. Based on the size and load of the application, select appropriate server hardware, including the server's processor, memory size, hard disk space, etc. In addition, the server's network environment also needs to be considered to ensure that the network connection is stable and high-speed.

2. Operating system selection

Selecting the appropriate operating system is also a key step in server deployment. For PHP projects, the common operating systems on the market are Linux and Windows Server. The Linux operating system is often considered the preferred operating system for PHP because it is not only open source and free, but also has better compatibility and performance advantages with PHP. Although the Windows Server operating system can also be used as a server environment for PHP, its performance and stability may not be as good as Linux.

3. Web server selection

Selecting an appropriate Web server is also an important part of server deployment. Currently, commonly used web servers include Apache, Nginx, IIS, etc. Among them, Apache is one of the most popular web servers. It supports the modular architecture of PHP and can parse and execute PHP by loading the corresponding modules. Nginx is a high-performance asynchronous event-driven web server. It is usually used in conjunction with PHP-FPM (FastCGI Process Manager) to better handle high concurrent requests. IIS is a web server developed by Microsoft, which is a more ideal choice for the Windows Server operating system.

4. PHP version selection

When deploying the server, you also need to select the appropriate PHP version. There may be some different features and performance optimizations between different PHP versions. Usually, choosing the latest stable version is a better choice. The latest version is available for download on the PHP official website, and can be compiled and installed as needed.

5. Configuration file optimization

After the server deployment is completed, the relevant configuration files need to be optimized. For example, adjust parameters in the php.ini configuration file, such as memory limits, execution time limits, and file upload limits, to adapt to the actual needs of the project. In addition, you can also perform some performance optimization on the server through the Apache or Nginx configuration file, such as enabling compression, turning on caching, etc.

2. Performance Monitoring

After the server deployment is completed, we also need to monitor the performance of the application to ensure stable and efficient operation.

1. System monitoring tools

You can use some system monitoring tools to collect server performance data, such as CPU usage, memory usage, disk space, etc. Commonly used system monitoring tools include Zabbix, Nagios, etc. Through these tools, the running status of the server can be monitored in real time and problems can be discovered and solved in a timely manner.

2. Database optimization

For applications that use databases, database performance optimization is particularly important. The response speed and concurrency performance of the database can be improved through index optimization, query optimization, cache optimization, etc. MySQL provides some tools and guides to help optimize database performance, such as Explain statements, Slow Query Log, etc.

3. Code Optimization

In addition to server and database optimization, application performance can also be improved by optimizing PHP code. For example, use more efficient algorithms, avoid repeated queries, reduce database operations, etc. In addition, you can also reduce the load on the server by using caching technology, such as using Redis, Memcached, etc.

Summary:

In-depth study of the underlying development principles of PHP, especially knowledge of server deployment and performance monitoring, is very important to improve the performance and stability of applications. By understanding server deployment related knowledge such as hardware environment selection, operating system selection, Web server selection, PHP version selection, etc., as well as performance monitoring related knowledge such as system monitoring tools, database optimization, code optimization, etc., we can better optimize applications and improve users experience to maintain stable and efficient operation in high-concurrency environments.
