请求限制的语法

    limit_conn_zone(连接限制) $binary_remote_addr zone=conn_zone:1m;  
    limit_req_zone(请求限制) $binary_remote_addr(请求ip) zone=req_zone(名称):1m(空间大小) rate=1r/s(一秒一次);
server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;


    location / {
        root /opt/app/code;
        limit_conn conn_zone 1;(一时刻只能处理一下连接请求)
        #limit_req zone=req_zone burst=3(最后3请求个放到下一秒执行) nodelay;
        #limit_req zone=req_zone burst=3;
        #limit_req zone=req_zone; (启动请求限制)
        index  index.html index.htm;
