Check Nginx's nginx.conf file, and you can see such a message
#access_log logs/access.log main;
This indicates that the file of the server access log is logs/host.access.log in the format of "main".

In addition to the main format, you can customize other formats by recombining the above parameters.
The default log of nginx is stored in logs/access.log, but different logs are allowed for different servers. Only the following statements need to be added under the corresponding server
access_log logs/access_8080.log mylog; #Declare alog #logStorage directory and name #logformat(Customizable)
After modifying nginx.conf, you need to restart Nginx for the configuration to take effect
