PS: I have been using Nginx for two or three years. now I often encounter some basic questions from new users. I have no time to answer them one by one. it took me some time this afternoon, based on your experience, I will share the main configuration parameters of Nginx and some network content. this is the most complete Chinese description of Nginx configuration parameters. For more detailed module parameters, see: http://wiki.nginx.org/Main# Define the number of Nginx processes run by the user and user group www; # set to equal to the total number of CPU cores. Worker_processes 8; # global error log definition type, [debug | info | notice | warn | error | crit] error_log ar/logstores/error. log info; # process file pid ar/runner-up. pid; # the maximum number of file descriptors opened by an nginx process. the theoretical value should be the maximum number of opened files (the system value ulimit-n, however, nginx allocation requests are uneven, so we recommend that you keep them consistent with the ulimit-n value. Worker_rlimit_nofile 65535; # working mode and maximum number of connections events {# refer to the event model, use [kqueue | rtsig | epoll |/dev/poll | select | poll]; the epoll model is a high-performance network I/O model in the kernel of Linux 2.6 or later versions. if you are running on FreeBSD, use the kqueue model. Use epoll; # maximum number of connections (maximum number of connections = number of connections * number of processes) worker_connections 65535;} # set http server http {include mime. types; # default_type application/octet-stream; # default file type # charset UTF-8; # server_names_hash_bucket_size 128; # client_header_buffer_size 32 k for the hash table of the server name; # the size of the uploaded file is limited to large_client_header_buffers 4 64 k; # set client_max_body_size 8 m for request slowdown; # set sendfile on; # enable the efficient file transmission mode. the sendfile command specifies whether nginx calls the sendfile function to output files, For general applications that are set to on, if used for downloading and other application disk I/O heavy load applications, you can set it to off to balance the disk and network I/O processing speed and reduce the system load. Note: If the image is not displayed properly, change it to off. Autoindex on; # enable directory list access, which is suitable for downloading servers. it is disabled by default. Tcp_nopush on; # prevent network congestion tcp_nodelay on; # prevent network congestion keepalive_timeout 120; # Long connection timeout time, in seconds # FastCGI-related parameters are used to improve website performance: reduces resource usage and increases access speed.
