Linux - Nginx 配置优化

本文主要是介绍Linux - Nginx 配置优化，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

# 主要配置文件

#user  nobody;
worker_processes  auto;     #自动根据cpu分配多少个worker进程
worker_rlimit_nofile 65535;        #worker进程打开的最大值，同ulimit或者/etc/security/limits一起取最小值，如果service启动，需要注意LimitNOFILE的取值，反正取之间最小值
worker_priority -20;    #进程优先级，-20最高
worker_cpu_affinity auto; # CPU亲缘性，避免CPU来回切换，自动绑定CPU

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  100000;    #最大worker链接数，同上面limits文件一样取值
    accept_mutex  on; #惊群，高并发off，低并发on
    multi_accept on;    #开启时，每个worker接收多个网络链接
}


http {
    include       mime.types;    #支持的文件类型
    default_type  application/octet-stream;     #在mime.types找不到,用这个默认类似

    #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;
    server_tokens off;    #不显示nginx版本，也可自己源码编译，nginx.h更改自己的版本

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  60 65; # 保持链接时间，前者是实际时间，后者是用户看到的时间

#访问日志格式改为json格式，为后面ELK配合使用
    log_format access_json '{"@timestamp":"$time_iso8601",'
    '"host":"$server_addr",'    
    '"clientip":"$remote_addr",'
    '"size":$body_bytes_sent,'
    '"responsetime":$request_time,' #总的处理时间
    '"upstreamtime":"$upstream_response_time",'
    '"upstreamhost":"$upstream_addr",'   #后端应用服务器处理时间
    '"http_host":"$host",'
    '"uri":"$uri",'
    '"xff":"$http_x_forwarded_for",'
    '"referer":"$http_referer",'
    '"tcp_xff":"$proxy_protocol_addr",'
    '"http_user_agent":"$http_user_agent",'
    '"status":"$status"}';
