1.使用此模块
LoadModule deflate_module modules/mod_deflate.so

2.在conf文件底下加上

<ifmodule mod_deflate.c>  
    AddOutputFilterByType DEFLATE text/html text/plain text/css    #压缩类型
    DeflateCompressionLevel 9   #将输出内容压缩的程度
    SetOutputFilter DEFLATE   
    #DeflateFilterNote Input instream   
    #DeflateFilterNote Output outstream   
    #DeflateFilterNote Ratio ratio   
    #LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate   
    #CustomLog logs/deflate_log.log deflate   
</ifmodule>
