安装配置Apache服务器的mod_deflate模块

Thinkpad R60

RHEL 5

Apache 2.2.6

1>编译mod_deflate模块

#/usr/local/apache2/bin/apxs -i -c -a /home/sense/software/server/httpd-2.2.6/modules/filters/mod_deflate.c

apxs命令参数说明：

-i  此选项表示需要执行安装操作，以安装一个或多个动态共享对象到服务器的modules目录中。

-a  此选项自动增加一个LoadModule行到httpd.conf文件中，以激活此模块，或者，如果此行已经存在，则启用之。

-A  与 -a 选项类似，但是它增加的LoadModule命令有一个井号前缀(#)，即此模块已经准备就绪但尚未启用。

-c  此选项表示需要执行编译操作。它首先会编译C源程序(.c)files为对应的目标代码文件(.o)，然后连接这些目标代码和files中其余的目标代码文件(.o和.a)，以生成动态共享对象dsofile 。如果没有指定 -o 选项，则此输出文件名由files中的第一个文件名推测得到，也就是默认为mod_name.so 。

# Dynamic Shared Object (DSO) Support

#

# To be able to use the functionality of a module which was built as a DSO you

# have to place corresponding `LoadModule’ lines at this location so the

# directives contained in it are actually available _before_ they are used.

# Statically compiled modules (those listed by `httpd -l’) do not need

# to be loaded here.

#

# Example:

# LoadModule foo_module modules/mod_foo.so

LoadModule php5_module        modules/libphp5.so

LoadModule deflate_module     modules/mod_deflate.so

#

2>配置apache使用deflate模块

设置php.ini，关闭其自身的压缩机制:

#vi /usr/local/php/lib/php.ini

=================================================

output_buffering = Off

output_handler =

zlib.output_compression = Off

=================================================

设置http.conf:

#vi /usr/local/apache2/conf/httpd.conf

=============================================================================

LoadModule php5_module        modules/libphp5.so

LoadModule deflate_module     modules/mod_deflate.so

3>错误处理：

# /usr/local/apache2/bin/apachectl -t

Syntax error on line 423 of /usr/local/apache2/conf/httpd.conf:

Invalid command ’Header’, perhaps misspelled or defined by a module not included in the server configuration

解决方案：安装mod_headers.c模块

/usr/local/apache2/bin/apxs -i -c -a /home/sense/software/server/httpd-2.2.6/modules/metadata/mod_headers.c

重新测试：

# /usr/local/apache2/bin/apachectl -t

httpd: Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName

Syntax OK

4>日志检测
