apache安装完成后，如果没有开启gzip，会因为个别js和css文件较大，影响网站打开速度。

在通过根目录.htaccess文件开启gzip压缩的时候，有apache2.4会报500错误。查看站点错误日志，提示'AddOutputFilterByType', perhaps misspelled or defined by a module not included in the server configuration

这种情况，需要核实apache的配置文件http.conf是否开启了filter_module，如果没有，需要设置载入filter_module。在http.conf文件大概113行，

LoadModule filter_module modules/mod_filter.so

去掉前面的#，重载apache配置

.htaccess配置文件中对应的设置内容为

  AddOutputFilterByType DEFLATE application/javascript
  AddOutputFilterByType DEFLATE application/rss+xml
  AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
  AddOutputFilterByType DEFLATE application/x-font
  AddOutputFilterByType DEFLATE application/x-font-opentype
  AddOutputFilterByType DEFLATE application/x-font-otf
  AddOutputFilterByType DEFLATE application/x-font-truetype
  AddOutputFilterByType DEFLATE application/x-font-ttf
  AddOutputFilterByType DEFLATE application/x-javascript
  AddOutputFilterByType DEFLATE application/xhtml+xml
  AddOutputFilterByType DEFLATE application/xml
  AddOutputFilterByType DEFLATE font/opentype
  AddOutputFilterByType DEFLATE font/otf
  AddOutputFilterByType DEFLATE font/ttf
  AddOutputFilterByType DEFLATE image/svg+xml
  AddOutputFilterByType DEFLATE image/x-icon
  AddOutputFilterByType DEFLATE text/css
  AddOutputFilterByType DEFLATE text/html
  AddOutputFilterByType DEFLATE text/javascript
  AddOutputFilterByType DEFLATE text/plain
  AddOutputFilterByType DEFLATE text/xml

设置完成后，css和js的http响应头可以看出，传输过程都已经开启了gzip压缩传输。
