nginx 配置文件讲解 （二）

nginx.conf配置文件

Nginx配置文件主要分成四部分

1. main（全局设置）

2. server（主机设置）

3. upstream（上游服务器设置，主要为反向代理、负载均衡相关配置）

4. location（URL匹配特定位置后的设置），每部分包含若干个指令

通用

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 ;
}
  
# 很重要的虚拟主机配置
server {
listen 80;
server_name itoatest.example.com;
root /apps/oaapp;
  
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
}
