keepalive_timeout

http has a keepalive mode, which tells the webserver to keep the tcp connection open after processing a request. If it receives other requests from the client, the server will use this unclosed connection without establishing another connection.

http keep-alive, every request for a web page is http (pictures, css, etc.), and to open an http request, you need to establish a tcp connection first, and if a page has to open and close a request for each request TCP connections will cause a waste of resources. keepalive_timeout is the time that when an HTTP request is completed, its TCP connection will remain. If there is another HTTP request at this time, the TCP connection will be reused. If there are no new requests Come over before closing its tcp connection

# Configuration section: http, default 75s

keepalive_timeout 60;

  • send_timeout: Send data to the client Client timeout, default is 60s. If the client does not receive 1 byte within 60 consecutive seconds, the connection is closed

  • proxy_connect_timeout: The connection timeout between nginx and upstream server

  • proxy_read_timeout: nginx receives upstream server data timeout, default is 60s, if 1 byte is not received within 60 consecutive seconds, the connection is closed

  • proxy_send_timeout: nginx sends Timeout for data to upstream server, default is 60s. If 1 byte is not sent within 60 consecutive seconds, the connection is closed

so_timeout:

When the user and server enable tcp connection --> This connection has no traffic for a long time (so_keepalive timeout) --> The server sends a detection packet to see if the user still exists --> If the detection packet is not returned, close the tcp connection

so_keepalive=on|off|[keepidle]:[keepintvl]:[keepcnt]
Copy after login
so_keepalive=30m::10
  will set the idle timeout (tcp_keepidle) to 30 minutes, leave the probe interval (tcp_keepintvl) at its system default, and set the probes count (tcp_keepcnt) to 10 probes.
Copy after login

Only one of the above three parameters can be used, and cannot be used at the same time, such as so_keepalive=on, so_keepalive=off or so_keepalive=30s:: (meaning waiting for 30s without data packets to send detection packets)
