Nginx.conf详解

一、nginx.conf详解

#运行用户
user nginx;
#启动进程,通常设置成和cpu的数量相等
worker_processes 1;

#全局错误日志及PID文件
error_log /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

#工作模式及连接数上限
events {
    use   epoll;               #epoll是多路复用IO(I/O Multiplexing)中的一种方式,但是仅用于linux2.6以上内核,可以大大提高nginx的性能
    worker_connections 1024; #单个后台worker process进程的最大并发链接数
    #multi_accept on;
}

#设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
    #设定mime类型,类型由mime.type文件定义
    include       /etc/nginx/mime.types;
    default_type application/octet-stream;
    #设定日志格式
    access_log    /var/log/nginx/access.log;

    #sendfile 指令指定 nginx 是否调用 sendfile 函数（zero copy 方式）来输出文件，对于普通应用，
    #必须设为 on,如果用来进行下载等应用磁盘IO重负载应用，可设置为 off，以平衡磁盘与网络I/O处理速度，降低系统的uptime.
    sendfile        on;
    #tcp_nopush     on;

    #连接超时时间
    #keepalive_timeout 0;
    keepalive_timeout 65;
    tcp_nodelay        on;

    #设定请求缓冲
  proxy_connect_timeout 5;
  proxy_read_timeout 60;
  proxy_send_timeout 5;
  proxy_buffer_size 16k;
  proxy_buffers 4 64k;
  proxy_busy_buffers_size 128k;
  proxy_temp_file_write_size 128k;
  server_names_hash_bucket_size 128;
  client_header_buffer_size 32k;
  large_client_header_buffers 4 32K;
  client_max_body_size 8m;
  client_body_buffer_size 512k;



    #开启gzip压缩
    gzip on;
    gzip_disable "MSIE [1-6].(?!.*SV1)";
    gzip_min_length 1k;
  gzip_buffers 4 16k;
  gzip_http_version 1.1;
  gzip_comp_level 2;
  gzip_types text/plain application/x-javascript text/css application/xml;
  gzip_vary on;


  include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;

    #设定负载均衡的服务器列表
    #upstream mysvr {
    #weigth参数表示权值，权值越高被分配到的几率越大
    #本机上的Squid开启3128端口
    #server 192.168.8.1:3128 weight=5;
    #server 192.168.8.2:80 weight=1;
    #server 192.168.8.3:80 weight=6;
    #}
    upstream tomcat_server {
     server 127.0.0.1:8080;
    }


   server {
        #侦听80端口

        #定义使用www.xx.com访问
        server_name 127.0.0.1;

        #设定本虚拟主机的访问日志
        access_log logs/www.xx.com.access.log main;

        #默认请求
      location / {
            root   /www;      #定义服务器的默认网站根目录位置
            index index.html index.htm index.jsp default.jsp index.do default.do index.php default.php; #定义首页索引文件的名称
            fastcgi_pass 127.0.0.1;
            fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
            include /etc/nginx/fastcgi_params;
      }

    #tomcat add start<<
    if (-d $request_filename)
    {
       rewrite ^/(.*)([^/])$http://$host/$1$2/ permanent;
    }

    #jsp请求处理
    location ~ .(jsp|jspx|do)?$ {
      proxy_set_header Host $host;
      proxy_set_header X-Forwarded-For $remote_addr;
      proxy_pass http://tomcat_server;
    }
    #tomcat add end>>

      # 定义错误提示页面
      error_page 404              /404.html;
        location = /404.html {
           root   /www;
        }
      error_page   500 502 503 504 /50x.html;
          location = /50x.html {
          root   /www;
      }

      #静态文件，nginx自己处理
      location ~ ^/(images|javascript|js|css|flash|media|static)/ {
          root /var/www/virtual/htdocs;
          #过期30天，静态文件不怎么更新，过期可以设大一点，如果频繁更新，则可以设置得小一点。
          expires 30d;
      }

      #PHP 脚本请求全部转发到 FastCGI处理. 使用FastCGI默认配置.
      location ~ .php$ {
          root /root;
          fastcgi_pass 127.0.0.1:9000;
          fastcgi_index index.php;
          fastcgi_param SCRIPT_FILENAME /usr/local/apache2/htdocs$fastcgi_script_name;
          include fastcgi_params;
      }

      #设定查看Nginx状态的地址
      location /NginxStatus {
          stub_status            on;
          access_log              on;
          auth_basic              "NginxStatus";
          auth_basic_user_file conf/htpasswd;
      }

      #禁止访问 .htxxx 文件
      location ~ /.ht {
          deny all;
      }
  }#server config end
}#http config end

二、能够运行jsp和php的nginx配置文件

worker_processes 1;

error_log /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections 1024;
}

    include       /etc/nginx/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 /var/log/nginx/access.log main;

    #new 1 start---------------
    server_names_hash_bucket_size 128;
