2. The following describes the default configuration file of nginx.

 

 
 

  
  
# User nobody; specifies the user and user group that starts nginx
  
  
Worker_processes 1; specify the number of processes that enable nginx and the logical cpu

  
  
 
  
  
# Error_log logs/error. log; location and format of error logs
  
  
# Error_log logs/error. log notice;
  
  
# Error_log logs/error. log info;
  
  
 
  
  
# Pid logs/nginx. pid; location of the process ID file
  
  
 
  
  
 
  
  
Events {
  
  
Worker_connections 1024; Maximum number of concurrent connections of a single backend worker process
  
  
Use epoll; use the epoll mechanism to greatly improve nginx Performance
  
  
}
  
  
 
  
  
 
  
  
Http {
  
  
Include mime. types; the type of html that can be processed.
  
  
Default_type application/octet-stream;
  
  
 
  
  
Custom log format
  
  
# Log_format main '$ remote_addr-$ remote_user [$ time_local] "$ request "'
  
  
# '$ Status $ body_bytes_sent "$ http_referer "'
  
  
# '"$ Http_user_agent" "$ http_x_forwarded_for "';
  
  
 
  
  
# Access_log logs/access. log main;
  
  
The sendfile command specifies whether nginx calls the sendfile function zero copy mode) to output files. For common applications,
It must be set to on. If it is used for application disk I/O heavy load such as downloading, it can be set to off to balance disk and network I/O processing speed and reduce system uptime.
  
  
Sendfile on;

  
  
# Tcp_nopush on;
  
  
 
  
  
# Keepalive_timeout 0;
  
  
Keepalive_timeout 65; keepalive timeout

  
  
 
  
  
# Gzip on; gzip enabled
  
  
 
  
  
Server {
  
  
Listen 80; listening port
  
  
Server_name localhost;
  
  
 
  
  
# Charset koi8-r;
  
  
 
  
  
# Access_log logs/host. access. log main;
  
  
 
  
  
Location /{
  
  
Root html; set the root directory

  
  
Index index.html index.htm; set the index starter File

  
  
}
  
  
 
  
  
# Error_page 404/404 .html;
  
  
 
  
  
# Redirect server error pages to the static page/50x.html
  
  
#
  
  
Error_page 500 502 503 x.html; defines error file redirection
  
  
Location =/50x.html {
  
  
Root html;
  
  
}
  
  
}
  
  
}
