1、第一步：打开IIS，启用HTTP压缩服务右击"网站"->"属性"，选择"服务&qu泠贾高框ot;。在"HTTP压缩"框中选中"压缩应用程序文件"和" 压缩静态文件"，按需要设置"临时目录"和"临时目录的最大限制
2、第二步：启用web服务
3、第三步：在服务中停止IIS Admin Service 服务开始 > 运行中输入：services.msc在服务里找到 IIS Admin Service 停止
4、第四步：修改MetaBase.xml开始 > 运行中输入 c:\windows\sy衡痕贤伎stem32\inetsrv，找到 MeteB锾攒揉敫ase.xml，先备份，在修改。（有的服务器不需要修改此文件便可以使用）搜索 Location ="/LM/W3SVC/Filters/Compression/gzip"仔细核对下代码：<IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/deflate" HcCompressionDll="%windir%\system32\inetsrv\gzip.dll" HcCreateFlags="0" HcDoDynamicCompression="TRUE" HcDoOnDemandCompression="TRUE" HcDoStaticCompression="FALSE" HcDynamicCompressionLevel="0" HcFileExtensions="htm html txt" HcOnDemandCompLevel="10" HcPriority="1" HcScriptFileExtensions="asp dll exe" > </IIsCompressionScheme> <IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/gzip" HcCompressionDll="%windir%\system32\inetsrv\gzip.dll" HcCreateFlags="1" HcDoDynamicCompression="TRUE" HcDoOnDemandCompression="TRUE" HcDoStaticCompression="TRUE" HcDynamicCompressionLevel="0" HcFileExtensions="htm html txt" HcOnDemandCompLevel="10" HcPriority="1" HcScriptFileExtensions="asp dll exe" > </IIsCompressionScheme>替换成：<IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/gzip" HcCompressionDll="%windir%\system32\inetsrv\gzip.dll" HcCreateFlags="1" HcDoDynamicCompression="TRUE" HcDoOnDemandCompression="TRUE" HcDoStaticCompression="TRUE" HcDynamicCompressionLevel="10" HcFileExtensions="html css js htm xml txt" HcOnDemandCompLevel="10" HcPriority="1" HcScriptFileExtensions="php dll" > </IIsCompressionScheme> <IIsCompressionScheme Location ="/LM/W3SVC/Filters/Compression/deflate" HcCompressionDll="%windir%\system32\inetsrv\gzip.dll" HcCreateFlags="2" HcDoDynamicCompression="TRUE" HcDoOnDemandCompression="TRUE" HcDoStaticCompression="TRUE" HcDynamicCompressionLevel="10" HcFileExtensions="html css js htm xml txt" HcOnDemandCompLevel="10" HcPriority="1" HcScriptFileExtensions="php dll" > </IIsCompressionScheme>然后在保存MeteBase.xml，保存好后再启动IIS。这样Gzip压缩就启用成功了。
