High-performance server architecture: Nginx configuration tips for PHP development

With the development of the Internet, high-performance server architecture has become one of the core issues in the development of various websites and applications. In PHP development technology, Nginx is the most common web server. Its excellent performance design and flexible configuration capabilities make it a powerful tool that can support high-performance server architecture for PHP development.

Among them, the performance of Nginx can be further improved by optimizing the configuration. In this article, we will share some Nginx configuration tips for PHP development to help you build a high-performance server architecture under high traffic.

1. Adjust the number of Nginx worker processes

By default, the number of Nginx worker processes will be automatically adjusted based on the number of server CPU cores. This setting allows Nginx to work properly, but if you want higher performance, it is recommended to manually set the number of worker processes to 2 times the number of server CPU cores.

For example, if your server has 8 CPU cores, you can set the number of workers to 16. This can make full use of server resources and improve Nginx's performance and response speed.

2. Turn on Nginx Gzip compression

Turning on Nginx Gzip compression can reduce the amount of data transmission, thereby improving the website response speed. To do this, you need to add the following line to your Nginx configuration file:

gzip on;
gzip_disable "MSIE [1-6].(?!.*SV1)";
gzip_types text/ plain text/css application/json application/javascript text/xml application/xml application/xml rss text/javascript;

This will enable Gzip compression and define the file types that are allowed to be compressed.

3. Optimize Nginx cache

Nginx cache can greatly improve website response speed and user experience. You can set the cache time to control the cache, for example:

proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=my_cache:10m inactive=60m;
server {
location / {

proxy_pass http://backend;
proxy_cache my_cache;
proxy_cache_valid 200 10m;
proxy_cache_valid 404 1m;

}
}

This configuration will enable a cache called "my_cache" with a cache time of 10 minutes. If the accessed URL does not exist in the cache, it will be Obtained from the backend server.

4. Using Nginx FastCGI Cache

Similar to Nginx cache, FastCGI cache can also greatly improve the performance of PHP applications. You can define the FastCGI cache using the following line in the Nginx configuration file:

fastcgi_cache_path /var/cache/nginx levels=1:2 keys_zone=my_cache:10m inactive=60m;
server {
location / {

try_files $uri =404;
fastcgi_pass unix:/var/run/php-fpm.sock;
fastcgi_cache my_cache;
fastcgi_cache_valid 200 60m;

}
}

This configuration will enable the FastCGI cache named "my_cache" with a cache time of 60 minutes.

5. Using Nginx Lua script

If you need to further customize the Nginx configuration, you can use a Lua script. This scripting language is very flexible and provides access to Nginx’s internal API, allowing you to implement any custom behavior you need.

To do this, in the Nginx configuration file, make sure to enable Nginx’s Lua module. For example:

location /example {
content_by_lua '

ngx.say("Hello, world!")

';
}

This code will enable Lua scripts and output under the /example URL "Hello, world!".

Conclusion

The above techniques are common configuration methods for Nginx server optimization in PHP development. With these tips, you can further improve your web application's performance and responsiveness, thereby improving user experience.
