 ./configure --prefix=/usr/local/nginx_server  --with-openssl=/usr/local --with-pcre --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-http_image_filter_module --with-http_slice_module --with-mail --with-threads --with-file-aio --with-stream --with-mail_ssl_module --with-stream_ssl_module --with- --with-http_image_filter_module ;

主要配置

location ~* /img/(.+)_(\d+)x(\d+)\.(jpg|jpeg|gif|png)$ {
        set $w $2;
        set $h $3;
        image_filter resize $w $h;
        image_filter_buffer 30M; 
        image_filter_interlace on;
        image_filter_jpeg_quality 80;
        try_files /$1.$4 /notfound.jpg;
        expires 1d;
        add_header 'Access-Control-Allow-Origin' '*';
        add_header 'Access-Control-Allow-Credentials' 'true';
