Nginx 限流笔记

Nginx采用的是漏桶算法

官方文档

http://nginx.org/en/docs/http/ngx_http_limit_req_module.html

http://hopestar.github.io/2013/06/08/nginx-limit-moule-note/

配置文件如下：

#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;



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;



sendfile on;

#tcp_nopush on;



#keepalive_timeout 0;

keepalive_timeout 65;



#rate limit

limit_conn_zone $binary_remote_addr zone=one:10m; #容器共使用10M的内存来对于IP传输开销

limit_req_zone $binary_remote_addr zone=req_one:20m rate=5r/s;



limit_conn one 1; #限制每个IP只能发起一个并发连接

limit_req zone=req_one burst=120;#请求排队



upstream hctp {

server 127.0.0.1:9090;

}

#gzip on;



server {

listen 8080;

server_name localhost;



#charset koi8-r;



#access_log logs/host.access.log main;





#location / {

# root html;

# index index.html index.htm;

#}





location / {

proxy_pass http://hctp/;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}



}

include servers/*;

}

 

使用jmeter 并发12请求，有拒绝请求
