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。

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>

</VirtualHost>

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;

    }

}
