Wherein, the process is completed in the program structure: a command object in a TCP (Transmission Control Protocol ) message defining delivery, for example, a process ID of a sending command, indicates a sequence number of the sending command between ngx _process process arrays, and generates a socket handle for communication. After the socket handle is obtained, a channel is opened, a command is sent before channel mode communication is used, the opened channel is closed, and the purpose of closing the socket to release resources is achieved, wherein Nginx defines the following commands for members: ngx_cmd_open_channel, ngx_cmd_close_channel, ngx_cmd_quench, ngx_cmd_cmd_wait, ngx_cmd_ TERMINATE, NGX _cmd_reopen.
