在CentOS上配置Nginx缓存策略主要涉及HTTP缓存和FastCGI缓存。以下是详细的配置步骤和策略解析:

HTTP缓存配置

  1. 配置缓存路径和参数
http {
    proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=my_cache:10m max_size=1g inactive=60m use_temp_path off;
}
  1. 在server块中配置缓存
server {
    listen 80;
    server_name example.com;

    location / {
        proxy_pass http://backend_server;
        proxy_cache my_cache;
        proxy_cache_valid 200 302 10m;
        proxy_cache_valid 404 1m;
        add_header X-Proxy-Cache $upstream_cache_status;
    }
}

FastCGI缓存配置

  1. 配置FastCGI缓存路径和参数
http {
    fastcgi_cache_path /var/cache/nginx levels=1:2 keys_zone=fcgi_cache:10m max_size=1g inactive=60m use_temp_path off;
}
  1. 在location块中配置FastCGI缓存
server {
    listen 80;
    server_name example.com;

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php-fpm/php-fpm.sock;
        fastcgi_index index.php;
        include fastcgi.conf;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        fastcgi_cache fcgi_cache;
        fastcgi_cache_valid 200 302 10m;
        fastcgi_cache_valid 404 1m;
        add_header X-FastCGI-Cache $upstream_cache_status;
    }
}

缓存策略解析

  1. 缓存类型
  1. 缓存控制
  1. 缓存优化建议

通过以上配置和策略,可以在CentOS上实现Nginx的高效缓存功能,从而提高网站性能和响应速度。
