1.安装动态库

gzip需要mod_deflate.so和mod_headers.so， 但是不像系统自带的apache，后来安装的apache是没有带这些库的。如果自带库，请直接跳到第二步。

[hubery@localhost ~]$ ls -l /etc/httpd/modules/

-rwxr-xr-x 1 root root 3699056 8月  12 04:36 libphp5.so

[hubery@localhost ~]$ ls /usr/local/apache2/modules/

Libraries have been installed in:
   /usr/local/apache2/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

2.配置支持

去掉注释或添加下面两段。

[hubery@localhost ~]$ cat /usr/local/apache2/conf/httpd.conf
#...
LoadModule deflate_module     modules/mod_deflate.so
LoadModule headers_module     modules/mod_headers.so
