Nginx 使用小结

1. 80端口公用问题多个域名访问

http {
include mime.types;
#公用80端口//就这里加一行就可以了
include /etc/nginx/vhosts/*.conf;
default_type application/octet-stream;
....
}

  1 #user  nobody;
  2 worker_processes  4; #nginx进程数，建议设置为等于CPU总核心数
  3 
  4 #error_log  logs/error.log;
  5 #error_log  logs/error.log  notice;
  6 #error_log  logs/error.log  info;

2. 数据流转发例如程序部署在 sever 1 ，sever0 做负载均衡，那么直接可以把数据流全量转发 https 好像也能按域名转发（没有实验）
