之前试过使用一个域名去访问多个yii应用（将域名指向网站根目录，而不是各应用的web目录），结果网址上会默认带上应用路径（比如：首页会变成 koko.vc/frontend/web/site/index）。其实yii可以配置各应用的默认路径，再配合.htaccess文件就可以完美解决这个问题。刚好看到有网友发了教程，就转载如下。

原文内容如下：

yii2的高级模板分为backend和frontend，最开始用yii的时候并没怎么在意，就使用了两个域名分别解析前后台。今天无意间看见
可以使用一个域名指向前后台。在这里记录一下，也可供参考。（注意，这里仅适用nginx和apache服务器）

1.修改 advanced/backend/config/main.PHP 文件如下:

	return [
'homeUrl' => '/admin',
'components' => [
    'request' => [
        'baseUrl' => '/admin',
    ],
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
    ],
],
];

2.同样修改 advanced/frontend/config/main.php 文件:

return [
'homeUrl' => '/',
'components' => [
    'request' => [
        'baseUrl' => '',
    ],
    'urlManager' => [
        'enablePrettyUrl' => true,
        'showScriptName' => false,
    ],
],

];

3.配置域名解析

<VirtualHost *:80>
ServerName advanced.loc
ServerAlias www.advanced.loc

DocumentRoot "/path/to/advanced"
<Directory "/path/to/advanced">
    AllowOverride All
</Directory>

4.新建一个.htaccess文件，写入一下内容。放在项目根目录advacnced下

# prevent directory listings
Options -Indexes
# follow symbolic links
Options FollowSymlinks
RewriteEngine on

RewriteCond %{REQUEST_URI} ^/admin/$
RewriteRule ^(admin)/$ /$1 [R=301,L]
RewriteCond %{REQUEST_URI} ^/admin
RewriteRule ^admin(/.+)?$ /backend/web/$1 [L,PT]

RewriteCond %{REQUEST_URI} ^.*$
RewriteRule ^(.*)$ /frontend/web/$1

5.再次新建一个.htaccess文件，写入一下内容，在frontend和backend分别放一个。

# use mod_rewrite for pretty URL support
RewriteEngine on
# if a directory or a file exists, use the request directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward the request to index.php
RewriteRule . index.php

如果服务器是nginx，则更改nginx.cong文件，写入以下内容，具体路径根据自身实际情况进行修改

server {
charset      utf-8;
client_max_body_size  200M;

listen       80; ## listen for ipv4
#listen       [::]:80 default_server ipv6only=on; ## listen for ipv6

server_name  advanced.loc;
root         /path/to/advanced;

access_log   /path/to/logs/advanced.access.log main buffer=50k;
error_log    /path/to/logs/advanced.error.log warn;

location / {
    root  /path/to/advanced/frontend/web;

    try_files  $uri /frontend/web/index.php?$args;

    # avoiding processing of calls to non-existing static files by Yii
    location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
        access_log  off;
        expires  360d;

        try_files  $uri =404;
    }
}

location /admin {
    alias  /path/to/advanced/backend/web;

    rewrite  ^(/admin)/$ $1 permanent;
    try_files  $uri /backend/web/index.php?$args;
}

# avoiding processing of calls to non-existing static files by Yii
location ~ ^/admin/(.+\.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar))$ {
    access_log  off;
    expires  360d;

    rewrite  ^/admin/(.+)$ /backend/web/$1 break;
    rewrite  ^/admin/(.+)/(.+)$ /backend/web/$1/$2 break;
    try_files  $uri =404;
}

location ~ \.php$ {
    include  fastcgi_params;
    # check your /etc/php5/fpm/pool.d/www.conf to see if PHP-FPM is listening on a socket or port
    fastcgi_pass  unix:/var/run/php5-fpm.sock; ## listen for socket
    #fastcgi_pass  127.0.0.1:9000; ## listen for port
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    try_files  $uri =404;
}
#error_page  404 /404.html;

location = /requirements.php {
    deny all;
}

location ~ \.(ht|svn|git) {
    deny all;
}
}
