\#nginx进程,一般设置为和cpu核数一样  
worker\_processes 4;                          
\#错误日志存放目录   
error\_log  /data1/logs/error.log  crit;    
\#运行用户，默认即是nginx，可不设置  
user nginx         
\#进程pid存放位置  
pid        /application/nginx/nginx.pid;          
  
\#Specifies the value for maximum file descriptors that can be opened by this process.   
\#最大文件打开数（连接），可设置为系统优化后的ulimit -HSn的结果  
worker\_rlimit\_nofile 51200;

cpu亲和力配置，让不同的进程使用不同的cpu

worker\_cpu\_affinity 0001 0010 0100 1000 0001 00100100 1000;

\#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  
\}  
\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#  
http   
\{

include mime.types; \#文件扩展名与类型映射表  
default\_type application/octet-stream; \#默认文件类型

\#limit模块，可防范一定量的DDOS攻击  
\#用来存储session会话的状态，如下是为session分配一个名为one的10M的内存存储区，限制了每秒只接受一个ip的一次请求 1r/s  
  limit\_req\_zone $binary\_remote\_addr zone=one:10m rate=1r/s;  
  limit\_conn\_zone $binary\_remote\_addr zone=addr:10m;  
  include       mime.types;  
  default\_type  application/octet-stream;  
  
\#第三方模块lua防火墙  
    lua\_need\_request\_body on;  
    \#lua\_shared\_dict limit 50m;  
    lua\_package\_path "/application/nginx/conf/waf/?.lua";  
    init\_by\_lua\_file "/application/nginx/conf/waf/init.lua";  
    access\_by\_lua\_file "/application/nginx/conf/waf/access.lua";  
  
 \#设定请求缓存      
  server\_names\_hash\_bucket\_size 128;  
  client\_header\_buffer\_size 512k;  
  large\_client\_header\_buffers 4 512k;  
  client\_max\_body\_size 100m;

**\#****隐藏响应header和错误通知中的版本号**  
  server\_tokens off;  
  \#开启高效传输模式     
  sendfile on;

\-------------------------------------------------------------------------------------------------  
  \#激活tcp\_nopush参数可以允许把httpresponse header和文件的开始放在一个文件里发布，  
  积极的作用是减少网络报文段的数量  
  tcp\_nopush     on;  
  \#激活tcp\_nodelay，内核会等待将更多的字节组成一个数据包，从而提高I/O性能  
  tcp\_nodelay on;

## tcp\_nopush ##

 \#FastCGI相关参数：为了改善网站性能：减少资源占用，提高访问速度

fastcgi\_connect\_timeout 300;  
fastcgi\_send\_timeout 300;  
fastcgi\_read\_timeout 300;  
fastcgi\_buffer\_size 64k;  
fastcgi\_buffers 4 64k;  
fastcgi\_busy\_buffers\_size 128k;  
fastcgi\_temp\_file\_write\_size 128k;

\----------------------------------------------

\#连接超时时间，单位是秒  
  keepalive\_timeout 60;

\#开启gzip压缩功能  
    gzip on；  
 **\#****设置允许压缩的页面最小字节数，页面字节数从header头的Content-Length中获取。默认值是0，表示不管页面多大都进行压缩。建议设置成大于1K。如果小于1K可能会越压越大。**  
  gzip\_min\_length  1k;

**\#****压缩缓冲区大小。表示申请4个单位为16K的内存作为压缩结果流缓存，默认值是申请与原始数据大小相同的内存空间来存储gzip压缩结果。**  
  gzip\_buffers     4 16k;

**\#****压缩版本（默认1.1，前端为squid2.5时使用1.0）用于设置识别HTTP协议版本，默认是1.1，目前大部分浏览器已经支持GZIP解压，使用默认即可。**  
  gzip\_http\_version 1.0;

**\#****压缩比率。用来指定GZIP压缩比，1压缩比最小，处理速度最快；9压缩比最大，传输速度快，但处理最慢，也比较消耗cpu资源。**  
  gzip\_comp\_level 9;

**\#****用来指定压缩的类型，“text/html”类型总是会被压缩**  
  gzip\_types       text/plain application/x-javascript text/css application/xml;  
  **\#vary header****支持。该选项可以让前端的缓存服务器缓存经过GZIP压缩的页面，例如用**

**Squid缓存经过Nginx压缩的数据。**

gzip\_vary off;  
\#开启ssi支持，默认是off  
  ssi on;  
  ssi\_silent\_errors on;  
\#设置日志模式  
    log\_format  access  '$remote\_addr - $remote\_user \[$time\_local\] "$request" '  
                        '$status $body\_bytes\_sent "$http\_referer" '  
                        '"$http\_user\_agent" $http\_x\_forwarded\_for';

**\#****反向代理负载均衡设定部分**

**\#upstream****表示负载服务器池，定义名字为backend\_server的服务器池**  
upstream backend\_server \{  
    server   10.254.244.20:81 weight=1 max\_fails=2 fail\_timeout=30s;  
    server   10.254.242.40:81 weight=1 max\_fails=2 fail\_timeout=30s;  
    server   10.254.245.19:81 weight=1 max\_fails=2 fail\_timeout=30s;  
    server   10.254.243.39:81 weight=1 max\_fails=2 fail\_timeout=30s;  
  \#设置由 fail\_timeout 定义的时间段内连接该主机的失败次数，以此来断定 fail\_timeout 定义的时间段内该主机是否可用。默认情况下这个数值设置为 1。零值的话禁用这个数量的尝试。

设置在指定时间内连接到主机的失败次数，超过该次数该主机被认为不可用。

\#这里是在30s内尝试2次失败即认为主机不可用！
