【示例一】
运行用户
user www-data;
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;
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;
开启gzip压缩
gzip on;
gzip_disable “MSIE [1-6].(?!.*SV1)”;
设定请求缓冲
client_header_buffer_size 1k;
large_client_header_buffers 4 4k;
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;
}
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 /root; #定义服务器的默认网站根目录位置
index index.php index.html index.htm; #定义首页索引文件的名称
fastcgi_pass www.xx.com;
fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
include /etc/nginx/fastcgi_params;
}
定义错误提示页面
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /root;
}
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 /home/www/www$fastcgi_script_name;
include fastcgi_params;
}
设定查看Nginx状态的地址
location /NginxStatus {
stub_status on;
access_log on;
auth_basic “NginxStatus”;
auth_basic_user_file conf/htpasswd;
}
禁止访问 .htxxx 文件
location ~ /.ht {
deny all;
}
}
}
【示例二】
下面的nginx.conf简单的实现nginx在前端做反向代理服务器的例子，处理js、png等静态文件，jsp等动态请求转发到其它服务器tomcat：
user www www;
worker_processes 2;
error_log logs/error.log;
error_log logs/error.log notice;
error_log logs/error.log info;
pid logs/nginx.pid;
events {
use epoll;
worker_connections 2048;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr – $remote_user [$time_local] “$request” ‘
‘$status $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” “$http_x_forwarded_for”‘;
access_log logs/access.log main;
sendfile on;
tcp_nopush on;
keepalive_timeout 65;
gzip压缩功能设置
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 6;
gzip_types text/html text/plain text/css text/javascript application/json application/javascript application/x-javascript application/xml;
gzip_vary on;
http_proxy 设置
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 75;
proxy_send_timeout 75;
proxy_read_timeout 75;
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
proxy_temp_path /usr/local/nginx/proxy_temp 1 2;
设定负载均衡后台服务器列表
upstream backend {
ip_hash;
server 192.168.10.100:8080 max_fails=2 fail_timeout=30s ;
server 192.168.10.101:8080 max_fails=2 fail_timeout=30s ;
}
charset utf-8;
access_log logs/host.access.log main;
对 / 所有做负载均衡+反向代理
location / {
root /apps/oaapp;
index index.jsp index.html index.htm;
proxy_pass http://backend;
proxy_redirect off;
后端的Web服务器可以通过X-Forwarded-For获取用户真实IP
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
静态文件，nginx自己处理，不去backend请求tomcat
location ~* /download/ {
root /apps/oa/fs;
}
location ~ .*.(gif|jpg|jpeg|bmp|png|ico|txt|js|css)$
{
root /apps/oaapp;
expires 7d;
}
location /nginx_status {
stub_status on;
access_log off;
allow 192.168.10.0/24;
deny all;
}
location ~ ^/(WEB-INF)/ {
deny all;
}
error_page 404 /404.html;
redirect server error pages to the static page /50x.html
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
其它虚拟主机，server 指令开始
