数据库连接池配置应增大：
datasource:
  dynamic:
    #设置默认的数据源或数据源组，默认值为master
    primary: law
    druid:
      initialSize: 20
      minIdle: 20
      maxActive: 3000
      maxWait: 60000
      queryTimeout: 60000
      timeBetweenEvictionRunsMillis: 60000
      minEvictableIdleTimeMillis: 20000
      validationQuery: SELECT 'x'
      testWhileIdle: true
      testOnBorrow: true
      testOnReturn: true
      poolPreparedStatements: true
      maxPoolPreparedStatementPerConnectionSize: 20

mysql数据库配置：

max_connections=1000
max_user_connections=500
net_read_timeout = 2000

jmeter配置：

1、添加线程组

2、线程组下添加http请求

3、线程组下添加http信息头管理器

4、线程组下添加查看结果树

5、线程组下添加汇总报告

nginx配置

user www www;
worker_processes auto;
error_log logs/error.log notice;
pid logs/nginx.pid;
worker_rlimit_nofile 20480;
events {
use epoll;
worker_connections 20480;
}

http {
include mime.types;
default_type application/octet-stream;
resolver 114.114.114.114;
server_names_hash_bucket_size 128;
client_header_buffer_size 64k;
large_client_header_buffers 8 128k;
client_max_body_size 100m;
client_body_buffer_size 30M;
limit_conn_zone $binary_remote_addr zone=one:32k;
sendfile on;
tcp_nopush on;
proxy_read_timeout 240s;
keepalive_timeout 600;
tcp_nodelay on;

gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;

log_format wwwlogs '$remote_addr - $remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for';
#access_log logs/access.log;
#log_format access-upstream '$time_iso8601|$request|$remote_addr|$upstream_response_time|$http_user_agent|$http_x_forwarded_for';
map $time_iso8601 $logdate {
'~^(?<ymd>\d{4}-\d{2}-\d{2})' $ymd;
default 'date-not-found';
}
access_log logs/access-$logdate.log ;
#include default.conf;
include vhost/*.conf;

#upstream配置

upstream springboot{
server 192.168.1.xx:端口;
server 192.168.1.xx:端口;
}

}

代理的location下配置反向代理

   location /boot/ {
       proxy_pass http://springboot;(upstream的命名的名称)
   proxy_set_header Host $host:$server_port;
   proxy_set_header X-Real-IP $host:$remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "upgrade";
}

jmeter可能出现的报错或异常

1、java.net.socketException:socket closed(强制停止线程，连接中断产生的错误，正常压测我们等测试结束就好，不用强制停止。)

2、java.net.SocketTimeoutExpetion:Read timed out(这个错误的导致是由于请求接口设置的请求超时与请求响应超时设置过小所致。)

3、jmeter压测报java.net.SocketException:Connection reset: windows电脑需配置注册表

MaxUserPort：最大动态端口数（Default = 5000, Max = 65534）

TcpTimedWaitDelay：TCP等待延迟时间（30）

TcpNumConnections：TCP最大连接数（Default = 16,777,214）

MaxFreeTcbs：最大TCP控制块（1000-2000）

MaxHashTableSize：最大TCB Hash table数量（64-65536）

解析中值为10进制，下方脚本已全转换为16进制

实际在注册表新增：

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] 新建：
