nginx清理Proxy Cache缓存

1. 编译Nginx

#前提：需要重新编译nginx
./configure  –add-module=/root/ngx_cache_purge-2.3 

Nginx 添加如下配置

cat conf.d/web.conf

#硬盘缓存
#proxy_cache_path /data/A/proxy_cache levels=2:2 keys_zone=music:200m inactive=1d max_size=12h;

#内存缓存
proxy_temp_path /dev/shm/temp;
proxy_cache_path /dev/shm/cache levels=2:2:2 keys_zone=cache_static:200m inactive=1d max_size=8g;

  
server  {
       #clean cache
        location ~ /purge(/.*) {
             allow  all;
             proxy_cache_purge $keys_zone $1$is_args$args;
        }
}

2.清理测试：

清理指定页面的缓存

curl -H "Host:x.x.x.com" http://x.x.x.x:443/purge/a.png

通过请求purge二级目录下的a.png来实现缓存清理目的

注：这里的purge二级目录不需要真是存在

3. Nginx完整配置文件-参考

#使用内存缓存
proxy_temp_path /dev/shm/temp;
proxy_cache_path /dev/shm/cache levels=2:2:2 keys_zone=cache_static:200m inactive=1d max_size=8g;

server {
        listen 8081;
        server_name localhost;
        root /data/A/web/myth; 


        # svg, fonts
        location ~* \.(?:svgz?|ttf|ttc|otf|eot|woff2?)$ {
           add_header Access-Control-Allow-Origin "*";
           expires    7d;
           access_log off;
        }

        # gzip
        gzip            on;
        gzip_vary       on;
        gzip_proxied    any;
        gzip_comp_level 6;
        gzip_types      text/plain text/css text/xml application/json application/javascript application/rss+xml application/atom+xml image/svg+xml image/jpeg image/gif image/png;

        location = /favicon.ico {
           root /data/A/web/myth;
           log_not_found off;
           access_log off;
        }

        location / {
           index main.html;
        }
        
        location ~ \.php$ {  
           fastcgi_pass 127.0.0.1:9000;  
           fastcgi_index index.php;  
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;  
           include fastcgi_params;  
        }

       #clean cache
        location ~ /purge(/.*) {
             allow  all;
             proxy_cache_purge $keys_zone $1$is_args$args;
        }
  
        access_log  /var/log/nginx_access.log  main;
        error_log   /var/log/nginx_access.log;
}

server { 
     listen 8082;
     server_name localhost;

     location / {
         proxy_pass http://localhost:8081;
         proxy_set_header Host $host;
         proxy_cache_valid 200 304 12h;
         proxy_cache_valid any 10m;
         proxy_cache cache_static;
         proxy_cache_key $uri;   
         #memory cache verify
         #add_header X-Cache-Status $upstream_cache_status;
     }
     access_log  /var/log/nginx/proxy_access.log main;
     error_log  /var/log/nginx/proxy_access.log error;
}

前端负载均衡设置后端配置

localhost:8082
