Sendfile on

The # sendfile instruction specifies whether nginx calls the sendfile function (zero copy mode) to output files. For ordinary applications, it must be set to on. If it is used for downloading and other application disk IO heavy-load applications, it can be set to off to balance the processing speed of disk and network Ion O and reduce the system uptime.

Server 192.168.8.3:80 max_fails=1 fail_timeout=10s weight=10

The # weigth parameter represents the weight. The higher the weight, the greater the probability of being assigned.

The # max_fails parameter sets the number of failed attempts by Nginx to communicate with the server.

The # fail_timeout parameter sets the time period during which the server is considered unavailable and the time period for counting the number of failed attempts. The default is 10 seconds.
