普通
首先确认apache2配置
1. 开启 apache 的 mod_rewrite 模块
去掉LoadModule rewrite_module modules/mod_rewrite.so前的“#”符号；
2. 修改 apache 的 AllowOverride
把 AllowOverride None 修改为 AllowOverride All；
在/config/web.php中 ’components‘=>[] 中添加如下代码：
‘urlManager‘ => [ ???????????‘enablePrettyUrl‘ => true, ????????????‘showScriptName‘ => false,//隐藏index.php ?????????????//‘enableStrictParsing‘ => false, ????????????‘suffix‘ => ‘.html‘,//后缀，如果设置了此项，那么浏览器地址栏就必须带上.html后缀，否则会报404错误 ????????????‘rules‘ => [ ????????????????//‘<controller:\w+>/<action:\w+>‘=>‘<controller>/<action>‘, ????????????], ????????],
我们还需在index.php同级的目录下添加.htaccess文件：
打开记事本，输入以下代码：
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然后保存在与入口文件index.php同级的目录下，也就是/web目录下，文件名自己填.htaccess，文件类型选择 所有文件 (*.*) ，然后保存即可。
最后测试OK了
高级
修改 advanced/backend/config/main.php 文件如下:
return [ ???‘homeUrl‘ => ‘/admin‘, ???‘components‘ => [ ???????‘request‘ => [ ???????????‘baseUrl‘ => ‘/admin‘, ???????], ???????‘urlManager‘ => [ ???????????‘enablePrettyUrl‘ => true, ???????????‘showScriptName‘ => false, ???????], ???],];
同样修改 advanced/frontend/config/main.php 文件:
return [ ???‘homeUrl‘ => ‘/‘, ???‘components‘ => [ ???????‘request‘ => [ ???????????‘baseUrl‘ => ‘‘, ???????], ???????‘urlManager‘ => [ ???????????‘enablePrettyUrl‘ => true, ???????????‘showScriptName‘ => false, ???????], ???],];
然后在 advanced/backend/web 目录中创建 .htaccess 文件,advanced/frontend/web 相同.htaccess 文件 内容如下:
# use mod_rewrite for pretty URL supportRewriteEngine on# if a directory or a file exists, use the request directlyRewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-d# otherwise forward the request to index.phpRewriteRule . index.php至此,配置完毕.
Yii2掉index.php?r=
