搭建Nginx圖片服務器

搭建Nginx圖片服務器

Part-I 安裝Nginx

1. 安裝PCRE
2. 下載 ngx_cache_purge 並解壓，用來清除緩存
3. 下載Nginx並解壓
4. cd nginx-1.7.7
5. 編譯，--prefix使用默認值，則nginx安裝在/usr/local/nginx

   ./configure    --user=www    --group=www    --add-module=../ngx_cache_purge-1.0 --with-http_stub_status_module --with-http_ssl_module make && make install

Part-II 配置

vim /usr/local/nginx/conf/nginx.conf，並編輯以下：

user www www; worker_processes 8; error_log /data3/nginx/error.log crit; #error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info; pid /usr/local/nginx/nginx.pid; events { use epoll; worker_connections 65535; } http { include mime.types; default_type application/octet-stream; charset utf-8; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 300m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; client_body_buffer_size 512k; proxy_connect_timeout 5; proxy_read_timeout 60; proxy_send_timeout 5; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.1; gzip_comp_level 2; gzip_types text/plainapplication/x-javascript text/css application/xml; gzip_vary on; # proxy_temp_path 和 proxy_cache_path 必須在同一分區 proxy_temp_path /data0/proxy_temp_dir; # 設置web緩存區名稱爲cahche_one，內存緩存空間大小爲200M,1天沒有被訪問的內容自動清除硬盤緩存空間大小爲300G proxy_cache_path /data0/proxy_cache_dir levels=1:2 keys_zone=cache_one:200m inactive=1d max_size=30g; # upstream backend_server{ # server 192.168.1.121:80 weight=1 max_fail=2 fail_timeout=30s; # server 192.168.1.122:80 weight=1 max_fail=2 fail_timeout=30s; # server 192.168.1.123:80 weight=1 max_fail=2 fail_timeout=30s; # } #如下爲緩存服務器 log_format cache '***$time_local \n' ' $upstream_cache_status \n' ' $remote_addr, $http_x_forwarded_for \n' ' Cache-Control: $upstream_http_cache_control \n' ' Expires: $upstream_http_expires \n' ' "$request"($status) \n' ' "$http_user_agent" \n'; server { listen 80; server_name 192.168.1.120; location / { proxy_cache cache_one; # 對不一樣的HTTP狀態碼設置不一樣的緩存時間 proxy_cache_valid 200 304 12h; #以域名、URI、參數組合成web服務器的key值，Ngnix根據key值哈希，存儲緩存內容到二級緩存目錄內 proxy_cache_key $host$uri$is_args$args; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $remote_addr; #此處跳轉到真實圖片服務器 proxy_pass http://192.168.1.120:8080; access_log /data3/nginx/cache.log cache; expires 1d; } location ~ /purge(/.*){ #設置只容許指定的ip或ip段才能夠清除url緩存 #allow 127.0.0.1; #allow 192.168.0.0/16; #deny all; proxy_cache_purge cache_one $host$1$is_args$args; } # #擴展名爲.php、.jsp、.cig結尾的動態應用程序不緩存 # location ~.*\.(php|jsp|cgi)?$ # { # proxy_set_header Host $host; # proxy_set_header X-Forwarded-For $remote_addr; # proxy_pass http://backend_server; # } access_log off; #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} # deny access to .htaccess files, if Apache's document root # concurs with nginx's one # #location ~ /\.ht { # deny all; #} } #真實的圖片服務器 server{ listen 8080; server_name localhost; location /{ root /data0/images/; } #訪問日誌，通常都off掉 access_log /data3/nginx/access.log combined; } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} } 

到此，Nginx圖片服務區搭建完畢。 在/data0/images/下放入一張圖片 200.jpg測試之 訪問 http://192.168.1.120/200.jpg， cache_log記錄以下：
