Windows环境下Nginx缓存优化配置指南

### Nginx配置文件

#### 主配置文件：nginx.conf

```nginx
worker_processes 1;
events {
worker_connections 1024;
}

http {
include mime.types;
include proxy.conf;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}

# 缓存路径配置
proxy_cache_path /nginx/temp/existo levels=1:2 keys_zOne=EXISTO:10m inactive=5m max_size=2m;
proxy_cache_path /nginx/temp/blog levels=1:2 keys_zOne=BLOG:10m inactive=5m max_size=2m;
proxy_cache_path /nginx/temp/yafan levels=1:2 keys_zOne=YAFAN:10m inactive=5m max_size=2m;
proxy_cache_path /nginx/temp/safe levels=1:2 keys_zOne=SAFE:10m inactive=5m max_size=2m;
proxy_cache_path /nginx/temp/atimg levels=1:2 keys_zOne=ATIMG:100m inactive=5m max_size=2m;
proxy_cache_path /nginx/temp/zhuatu levels=1:2 keys_zOne=ZHUATU:10m inactive=5m max_size=2m;

# 各域名服务器配置
server {
listen 80;
server_name existo.cn www.existo.cn;
location / {
proxy_pass http://218.28.188.230:81;
proxy_cache EXISTO;
proxy_cache_key $uri;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
proxy_cache_min_uses 1;
}
}

server {
listen 80;
server_name blog.atimg.com;
location / {
proxy_pass http://218.28.188.230:81;
proxy_cache BLOG;
proxy_cache_key $uri;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
proxy_cache_min_uses 1;
}
}

server {
listen 80;
server_name yafan.atimg.com;
location / {
proxy_pass http://218.28.188.230:81;
proxy_cache YAFAN;
proxy_cache_key $uri;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
proxy_cache_min_uses 1;
}
}

server {
listen 80;
server_name safe.atimg.com;
location / {
proxy_pass http://218.28.188.230:81;
proxy_cache SAFE;
proxy_cache_key $uri;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
proxy_cache_min_uses 1;
}
}

server {
listen 80;
server_name atimg.com www.atimg.com;
location ~*\.(htm|html|shtml|swf|png|jpg|gif|jpeg|rar|css|js)$ {
index index.php;
proxy_pass http://218.28.188.230:81;
proxy_temp_path /nginx/temp/cache;
proxy_cache ATIMG;
proxy_cache_key $uri;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
proxy_cache_min_uses 1;
}
}

server {
listen 80;
server_name zhuatu.atimg.com;
location / {
proxy_pass http://218.28.188.230:81;
proxy_cache ZHUATU;
proxy_cache_key $uri;
proxy_cache_valid 200 302 1h;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
proxy_cache_min_uses 1;
}
}
}
```

#### 代理配置文件：proxy.conf

```nginx
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
# client_body_temp_path /var/nginx/client_body_temp;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
#proxy_send_lowat 12000;
proxy_buffer_size 32k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
# proxy_temp_path /var/nginx/proxy_temp;
proxy_ignore_client_abort on;
proxy_next_upstream error timeout invalid_header http_500 http_503 http_404;
proxy_max_temp_file_size 128m;
```

以上配置示例展示了如何在Windows环境中为多个子域名配置Nginx的缓存功能，通过合理设置缓存路径、缓存策略等参数，可以显著提升网站的响应速度和用户体验。
