Apache之deflate

1. 高级配置
   
   1. 使用mod_deflate模块压缩页面优化传输速度
      
      1. 适用场景：

(1) 节约带宽，额外消耗CPU；同时，可能有些较老浏览器不支持；

(2) 压缩适于压缩的资源，例如文件文件；

SetOutputFilter DEFLATE

# mod_deflate configuration

# Restrict compression to these MIME types

AddOutputFilterByType DEFLATE text/plain

AddOutputFilterByType DEFLATE text/html

AddOutputFilterByType DEFLATE application/xhtml+xml

AddOutputFilterByType DEFLATE text/xml

AddOutputFilterByType DEFLATE application/xml

AddOutputFilterByType DEFLATE application/x-javascript

AddOutputFilterByType DEFLATE text/javascript

AddOutputFilterByType DEFLATE text/css

# Level of compression (Highest 9 – Lowest 1)

DeflateCompressionLevel 9

# Netscape 4.x has some problems.

BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems

BrowserMatch ^Mozilla/4\.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine

BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

1. 配置方法
   1. 编辑配置文件

保证加载压缩模块

[root@repo conf.d]# vim /etc/httpd/conf.d/vritualhost.conf

LoadModule deflate_module modules/mod_deflate.so

添加压缩模板

SetOutputFilter DEFLATE

# mod_deflate configuration

# Restrict compression to these MIME types

AddOutputFilterByType DEFLATE text/plain

AddOutputFilterByType DEFLATE text/html

AddOutputFilterByType DEFLATE application/xhtml+xml

AddOutputFilterByType DEFLATE text/xml

AddOutputFilterByType DEFLATE application/xml

AddOutputFilterByType DEFLATE application/x-javascript

AddOutputFilterByType DEFLATE text/javascript

AddOutputFilterByType DEFLATE text/css

# Level of compression (Highest 9 – Lowest 1)

DeflateCompressionLevel 9

# Netscape 4.x has some problems.

BrowserMatch ^Mozilla/4 gzip-only-text/html

# Netscape 4.06-4.08 have some more problems

BrowserMatch ^Mozilla/4\.0[678] no-gzip

# MSIE masquerades as Netscape, but it is fine

BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

1. 测试

   压缩前

查看模块是否添加

[root@repo conf.d]# httpd -M | grep deflate

[root@mx2 samba]# curl -I www.cpe.com:8080/test.html

[root@mx2 samba]# curl -I –compressed www.cpe.com:8080/test.html
