前言

由于我springboot项目启动了两个docker应用实例 8080和8081端口，我就想做个nginx负载均衡

直接上配置文件nginx.conf（http配置）

#user  nobody;
#worker_processes  1;
 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
 
#pid        logs/nginx.pid;
 
 
events {
    worker_connections  1024;
}
 
 
http {
    include       mime.types;
    default_type  application/octet-stream;
 
    limit_req_zone $binary_remote_addr zone=one:15m rate=3r/s;
    include ip.conf;#封ip的文件
 
 
 
    #tomcat_server是负载均衡器的名字
    upstream tomcat_server {
	server localhost:8080 weight=1;
	server localhost:8081 weight=1;
}
