多域名共用80埠配置

配置檔案為nginx.conf, 一般安裝完，根據系統不同，可能存放位置(/usr/local/nginx/conf, /etc/nginx, or /usr/local/etc/nginx.) ^[5]

#應用一
server {
   listen 80;
   server_name app1.domain.com;
   location / {
      proxy_pass        http://app1/;
      proxy_redirect    off;
      proxy_set_header  Host  $host;
      proxy_set_header  X-Real-IP  $remote_addr;
      proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}
#應用二
server {
   listen 80;
   server_name app2.domain.com;
   location / {
      proxy_pass        http://app2/;
      proxy_redirect    off;
      proxy_set_header  Host  $host;
      proxy_set_header  X-Real-IP  $remote_addr;
      proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}

#負載均衡節點配置
upstream app1 {
     server 192.168.1.1;
     server 192.168.1.2;
     ip_hash;
 }
upstream app2 {
     server 192.168.1.3;
     server 192.168.1.4;
     ip_hash;
}
 

Nginx操作幫助

$ sudo nginx -h
nginx version: nginx/1.18.0 (Ubuntu)
Usage: nginx [-?hvVtTq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
  -?,-h         : this help
  -v            : show version and exit
  -V            : show version and configure options then exit
  -t            : test configuration and exit
  -T            : test configuration, dump it and exit
  -q            : suppress non-error messages during configuration testing
  -s signal     : send signal to a master process: stop, quit, reopen, reload
  -p prefix     : set prefix path (default: /usr/share/nginx/)
  -c filename   : set configuration file (default: /etc/nginx/nginx.conf)
  -g directives : set global directives out of configuration file
