Nginx static file access configuration to accelerate website response speed

Nginx is a high-performance web server software. Its power lies not only in processing dynamic content, but also in its ability to quickly process static files. In the traditional LAMP (Linux, Apache, MySQL, PHP) architecture, static files are often processed by Apache. However, because Apache's processing mechanism is different from Nginx, its response speed is relatively slow when processing a large number of static files. Therefore, by properly configuring Nginx's static file access method, the response speed of the website can be significantly improved.

Nginx static file access configuration is mainly implemented through the location directive. The following will introduce several common static file access configuration methods to speed up the response speed of the website.

1. Configure the root directory of static files

First, in the Nginx configuration file, we need to configure the root directory of static files. By setting the root directive, we can specify the directory where static files are stored.

location /static/ {
    root /var/www/html;
}

In the above example, /static/ is the URL path we use to access static files, and /var/www/html/ is the storage directory for static files. Such a configuration means that when the accessed URL starts with /static/, Nginx will search for the corresponding static file in the /var/www/html directory.

2. Configuring cache

In order to further speed up the response speed of the website, we can configure the cache to reduce access to disk IO. Through the expires directive, we can set the expiration time of static files, thereby telling the browser that static files can be loaded directly from the local cache during this time period.

location /static/ {
    root /var/www/html;
    expires 7d;
}

In the above example, expires 7d means that the expiration time of the static file is 7 days, so that if the static file does not change, the user can load it directly from the local when accessing the file again without having to Request to the server again.

3. Enable gzip compression

In addition to caching, enabling gzip compression is also an effective way to speed up website response. Through the gzip command, we can enable the gzip compression function of Nginx.

location /static/ {
    root /var/www/html;
    expires 7d;
    gzip on;
    gzip_types text/plain text/css application/javascript image/jpeg image/png;
}

In the above example, gzip on means enabling gzip compression function, and gzip_types specifies the file type that needs to be compressed. In this way, when the browser requests a file from the server, Nginx will compress the file and return it to the browser, thereby reducing the file size and increasing the transmission speed.

Through the above Nginx static file access configuration method, we can speed up the response speed of the website, thus improving the user experience. Of course, depending on the specific conditions of the website, we can also perform more in-depth configurations as needed, such as using CDN, load balancing and other technologies to further optimize the performance of the website.
