indicates the maximum number of handles that a process (such as a worker process) can open at the same time, which limits the maximum number of concurrent connections and is configured according to the actual situation. Net.ipv4.tcp_tw_reuse = 1: This parameter is set to 1, which means that the socket of the time-wait state is allowed to be re-used for new TCP connections, which makes sense for the server

in worker. Some important global data will be set during process startup, and the most important is the ngx_processes. Each time the master creates a worker, it puts a set ngx_process_t structure variable into ngx_processes, the length of the process is 1024. The newly created process is stored in the ngx_process_slot position. ngx_last_process is the next position of the last existing process in the Process Table. ngx_process_t is the process abstraction in
