提醒：千万不能用win电脑去运行web进行压测，win电脑没优化，并发从几百到2000不等，根本达不到上万的qps

gin web代码：https://blog.youkuaiyun.com/cabing2005/article/details/78884138

[root@ycnode2 yc]# cat 1-test.go 
package main

import (
  "time"

  "net/http"

  "github.com/gin-gonic/gin"
)

func main() {
  route := gin.Default()
  route.GET("/ping", func(c *gin.Context) {

    //time.Sleep(time.Millisecond * 1)
    c.String(http.StatusOK, "OK")
  })
  s := &http.Server{
    Addr:      ":8090",
    Handler:    route,
    ReadTimeout:  1 * time.Second,
    WriteTimeout:  1 * time.Second,
    MaxHeaderBytes: 1 << 20,
  }
  s.ListenAndServe()
}

直接压测

[root@ycnode1 tools]# ./wrk -c 1000 -t 10 -d 30 http://192.168.11.81:8090/ping

worker 1

我靠 nginx单核1万

[root@ycnode1 tools]# ./wrk -c 1000 -t 10 -d 30  http://192.168.11.81:8990/ping
Running 30s test @ http://192.168.11.81:8990/ping
 10 threads and 1000 connections
 Thread Stats  Avg   Stdev   Max  +/- Stdev
  Latency  50.67ms  79.71ms  1.99s  97.67%
  Req/Sec   1.12k  412.45   6.65k  79.56%
 332319 requests in 30.06s, 49.74MB read

抓包分析：

tcpdump -i ens33 host 192.168.11.82 and port 8090 -n -O -w package.cap

wireshark分析 http 请求 Connection： 字段如果为close 则为短链接

压测结果：

1、 wrk nginx gin网站代码在同一个服务器和 gin网站代码单独一个服务器区别不大只要套接字 fd句柄够用

2、 nginx配置长链接：https://www.cnblogs.com/liufarui/p/11075630.html

1、保持和client的长链接

http {

keepalive_timeout 60s;

}

2、 保持和server的长链接  https://www.cnblogs.com/liufarui/p/11075630.html
upstream backend {
 server 192.168.0.1：8080 weight=1 max_fails=2 fail_timeout=30s;
 server 192.168.0.2：8080 weight=1 max_fails=2 fail_timeout=30s;
 keepalive 300; // 这个很重要！
}  
server {
  listen 8080 default_server;
  server_name "";
    
  location / {
    proxy_pass http://backend;
    proxy_http_version 1.1;             # 设置http版本为1.1
    proxy_set_header Connection "";   # 设置Connection为长连接（默认为no）
  }
}
 我的知识盲点：
proxy_set_header Connection ""    必须设置这个，默认是close，导致依然是短链接

长链接的血案还可以参考：http://xiaorui.cc/archives/3495

3、 nginx worker 1的时候 qps=1.1万 2的时候 1.7万

4、proxy_set_header Connection ""

压测结果：

              total        used        free      shared  buff/cache   available
Mem:           1823         212         485           8        1125        1390
Swap:             0           0           0
 22:19:30 up  4:47,  3 users,  load average: 1.54, 0.41, 0.17
ESTABLISHED 1009   （tcp链接稳定在1000左右）
1005


5、#proxy_set_header Connection ""注释掉以后
              total        used        free      shared  buff/cache   available
Mem:           1823         207         490           8        1126        1394
Swap:             0           0           0
 22:22:04 up  4:49,  3 users,  load average: 2.32, 0.76, 0.31
CLOSE_WAIT 1
ESTABLISHED 888
FIN_WAIT1 73
FIN_WAIT2 3
TIME_WAIT 6718   （存在大量的TIME_WAIT）
927

观测脚本

[root@ycnode2 script]# cat 1.sh 
#!/bin/sh


while true
do
    free -m && uptime 
    netstat -n | awk '/^tcp/ {++S[$NF]} END {for(a in S) print a, S[a]}'   #查看各种状态的TCP链接
    netstat -ant |grep 8090|grep ESTABLISHED|wc -l    #查看当前存在已建立的TCP链接
    sleep 1
done
