Nginx virtual host optimization configuration, improve website performance and user experience

Introduction:
Nowadays, with the continuous development of the Internet, the number of visits to the website is also increasing. As the entrance to the website, the optimized configuration of Nginx plays a crucial role in improving website performance and user experience. This article will introduce some methods for optimizing the configuration of Nginx virtual hosts, along with code examples so that you can better understand and apply them.

1. Virtual host configuration
Virtual host is an important concept in Nginx. Through the configuration of virtual host, we can point multiple domain names to the same server and improve the utilization of server resources. The following is a configuration example of a virtual host:

server {
    listen 80;
    server_name example.com;
    root /var/www/example;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}
Copy after login

In the example, we specify a domain name example.com through server_name and bind it to /var/www/example directory, when a user accesses this domain name, it will automatically look for the index.html file under /var/www/example. In addition, the configuration in the location block enables Nginx to search for static files first, improving the efficiency of file search.

2. Enable gzip compression
Enabling gzip compression can compress web page content, reduce the amount of data transmitted, and improve page loading speed. The following is a configuration example to enable gzip compression:

gzip on;
gzip_min_length 1024;
gzip_types text/plain text/css application/javascript;
gzip_comp_level 6;
gzip_vary on;
Copy after login

In the above example, gzip onenables gzip compression, gzip_min_length specifies the minimum compressed file length of 1024 bytes, Files smaller than this length will not be compressed. gzip_types specifies the file types to be compressed as ordinary text, CSS and JavaScript files, gzip_comp_level specifies the compression level as 6, gzip_vary is used to tell the browser whether to use gzip compression.

3. Configure cache
By using cache, you can reduce requests to the server and improve the response speed and user experience of the website. The following is an example of configuring the cache:

proxy_cache_path /var/nginx/cache levels=1:2 keys_zone=my_cache:10m max_size=10g inactive=60m;
proxy_temp_path /var/nginx/tmp;

server {
    ...
    
    location / {
        proxy_cache my_cache;
        proxy_cache_valid 200 302 12h;
        proxy_cache_valid 404 1m;
        proxy_cache_use_stale error timeout updating http_500 http_502 http_503 http_504;
        proxy_cache_bypass $http_cookie;
    }
}
Copy after login

In the example, proxy_cache_path specifies the storage path and related configuration of the cache file, and proxy_cache specifies the cache name used. proxy_cache_valid specifies the validity period of the cache, proxy_cache_use_stale is used to specify the strategy when obtaining data from the cache, proxy_cache_bypass is used to specify the case where the cache is not used, and is judged by Cookie in the request to determine whether to use caching.

Conclusion:
By optimizing the configuration of the Nginx virtual host, we can improve the performance and user experience of the website. This article gives relevant code examples from the aspects of virtual host configuration, enabling gzip compression and configuring cache. I hope the content of this article can be helpful to your Nginx optimization configuration!
