Invalid command ‘RewriteEngine’, perhaps mis-spelled or defined by a module not included in the server configuration的解决办法

apache error log上显示：

Invalid command ‘RewriteEngine’, perhaps mis-spelled or defined by a module not included in the server configuration

解决办法：

打开httpd.conf ，取消 LoadModule rewrite_module modules/mod_rewrite.so前的注释

这种错误容易导致网页显示500 internal server erro错误。
