Linux/nginx/パフォーマンス向上

静的ファイル圧縮

圧縮は個別confでなく全体で設定したほうがわかりやすいと思う。

vi /etc/nginx/nginx.conf

http {
   gzip              on;
   gzip_http_version 1.0;
   gzip_comp_level   6; #(1-9)
   gzip_proxied      any;
   gzip_vary         on;
   gzip_types        text/plain
                     text/xml
                     text/css
                     application/xml
                     application/xhtml+xml
                     application/rss+xml
                     application/atom_xml
                     application/javascript
                     application/x-javascript
                     application/x-httpd-php
                     application/json
                     text/javascript;
   gzip_disable      "MSIE [1-6]\.";
   gzip_disable      "Mozilla/4";
   gzip_buffers      16 8k;
   gzip_min_length   1100;
このさき略
}

gtmatrixの"Specify a Vary: Accept-Encoding header"対応はgzip_varyを追加すればok

ブラウザのキャッシュを活用する方法

vi /etc/nginx/conf.d/sample1.localhost.conf

   location ~* \.(txt|xml)$ {
       fastcgi_pass_header "X-Accel-Expires";
       expires 2d;
   }
   location ~* \.(jpg|gif|png|swf|css|js|inc|ico|pdf|flv|gz|woff)$ {
       fastcgi_pass_header "X-Accel-Expires";
       expires 365d;
   }
   location ~* \.(html|htm)$ {
       fastcgi_pass_header "X-Accel-Expires";
       expires 2h;
   }

ブラウザのキャッシュを活用する方法（apache連携編)

   location ~* \.(txt|xml)$ {
       fastcgi_pass_header "X-Accel-Expires";
       expires 2d;
       root    /var/www/zend/sample1/public;
       index   index.html;
   }
   location ~* \.(jpg|gif|png|swf|css|js|inc|ico|pdf|flv|gz|woff)$ {
       fastcgi_pass_header "X-Accel-Expires";
       expires 365d;
       root    /var/www/zend/sample1/public;
       index   index.html;
   }
   location ~* \.(html|htm)$ {
       fastcgi_pass_header "X-Accel-Expires";
       expires 2h;
       root    /var/www/zend/sample1/public;
       index   index.html;
   }
