Recommendations and Considerations for Optimizing Nginx Web Services

The following are some suggestions and considerations for optimizing Nginx web services:

1. Enable gzip compression: Enabling gzip compression can reduce HTTP response size, increase page loading speed, and reduce server load. Enable the gzip compression module in nginx.conf(enabled by default) and set appropriate parameters.

2. Use HTTP cache: Properly configured cache can reduce server load and improve user access speed. Different caching strategies can be configured based on response type, request type, request header and other conditions, and the caching time can be set according to business needs.

3. Limit the request rate: Malicious requests may consume a lot of server resources. You can use Nginx's limit_reqand limit_connmodules to limit the request rate and the number of concurrent connections to prevent abuse and attacks.

4. Avoid redundant modules: Select the required modules when compiling Nginx to avoid unnecessary modules occupying system resources and also reduce potential security risks.

5. Configure reverse proxy: Use Nginx's reverse proxy function to distribute requests to different servers to achieve load balancing and high availability. Different reverse proxy strategies can be implemented according to different businesses.

6. Support HTTP/2: HTTP/2 has significant advantages over HTTP/1.1 in terms of performance and security. Nginx supports HTTP/2, which can be enabled through the following steps:

   • nginx.confEnable the HTTP/2 module in :

     plaintextCopy code

     listen 443 ssl http2;

   • Configure SSL/TLS because HTTP/2 must use the HTTPS protocol.

7. Avoid long single requests: Long single requests may occupy too many server resources. It is recommended to set a reasonable timeout, for example proxy_read_timeout.

8. Use CDN: Using CDN can speed up the loading of images, static resources, etc. and reduce server load. Static resources can be hosted on a CDN platform and appropriate reverse proxy rules set in Nginx.

9. Set appropriate log levels: Properly recording access logs and error logs can facilitate subsequent analysis and troubleshooting, and will also generate a certain system IO load. It is recommended to set an appropriate log level to avoid unnecessary logging.

The above are some suggestions and precautions for optimizing Nginx web services. The specific optimization plan needs to be adjusted according to different business needs and server configuration.
