1.开启apache的mode_rewrite模块
去掉LoadModule rewrite_module modules/mod_rewrite.so前的“#”符号
确保<Directory "..."></Directory>中有“AllowOverride All”
2.在项目中的/protected/config/main.php中添加代码：
-----------------------------------------------------------------------------
'components'=>array(
...
'urlManager'=>array(
'urlFormat'=>'path',
'showScriptName'=>false,//注意false不要用引号括上
'urlSuffix'=>'.html',
'rules'=>array(
'sites'=>'site/index',
),
),
...
),
------------------------------------------------------------------------------
3.在与index.php文件同级目录下添加文件“.htaccess”，内容如下：
----------------------------------------------------------------
Options +FollowSymLinks
IndexIgnore */*
RewriteEngine on
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
