zend framework invalid command 'rewriteengine'解決辦法

zend framework tutorial時候,運行例子,瀏覽器報錯為:

the server encountered an internal error and was unable to complete your request. either the server is overloaded or there was an error in a cgi script.

apache error.log 中出現如下錯誤：

invalid command 'rewriteengine', perhaps mis-spelled or defined by a module not included in the server configuration

解決辦法:打開httpd.conf,取消 loadmodule rewrite_module modules/mod_rewrite.so前的注釋.
