Nginx服务器10000 并发优化测试(ab测试工具)

1.nginx监控模块

1)编译nginx,加上参数 --with-http_stub_status_module

#/usr/local/nginx/sbin/nginx -V
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module

#配置指令
  ./configure --prefix=/usr/local
    --user=nginx 
    --group=nginx
    --with-http_ssl_module
    --with-http_realip_module
    --http-client-body-temp-path=/usr/local/var/tmp/nginx/client 
    --http-proxy-temp-path=/usr/local/var/tmp/nginx/proxy --http-fastcgi-temp-path=/usr/local/var/tmp/nginx/fcgi --http-scgi-temp-path=/usr/local/var/tmp/nginx/scgi --http-uwsgi-temp-path=/usr/local/var/tmp/nginx/uwsgi --with-http_geoip_module --with-http_stub_status_module

2)修改nginx配置文件，添加监控状态配置

在nginx.conf的server块中添加如下代码

location /nginx_status {
    # Turn on nginx stats
    stub_status on;
    # I do not need logs for stats
    access_log off; # Security: Only allow access from 192.168.1.100 IP # #allow 192.168.1.100; # Send rest of the world to /dev/null # #deny all; }

解释:
 Active connections：对后端发起的活动连接数。
 Server accepts handled requests：Nginx总共处理了655个连接，成功创建655次握手(证明中间没有失败的)，总共处理了1985个请求。
 Reading：Nginx 读取到客户端的Header信息数。
 Writing：Nginx 返回给客户端的Header信息数。
 Waiting：开启keep-alive的情况下，这个值等于 active – (reading + writing)，意思就是Nginx已经处理完成，正在等候下一次请求指令的驻留连接。

/usr/local/nginx/sbin/nginx -t //测试配置是否正确 /usr/local/nginx/sbin/nginx -s reload

2.设置最大连接数（50000）/加快tcp连接数的回收/让空的tcp允许回收利用/关闭洪水攻击抵御

echo 50000 > /proc/sys/net/core/somaxconn

echo 1 > /proc/sys/net/ipv4/tcp_tw/recycle

echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse

echo 0 > /proc/sys/net/ipv4/tcp_syncookies 

3.设置打开更多文件数

ulimit -n 50000

vim /etc/nginx/nginx.conf

worker_rlimit_nofile 10000;    //nginx允许打开最大文件数10000-->写在全局 不是在events

events{

   worker_connections 10240;

}

/usr/sbin/nginx -t

/usr/sbin/nginx -s reload
