nginx怎麼配置 目錄別名phpmyadmin 到 localhost/phpmyadmin/

nginx如何配置 目錄別名phpmyadmin 到 localhost/phpmyadmin/
需求要求
在nginx中實現 類似Apache的 alias功能，將目錄 /phpmyadmin 指向 D:/wamp/apps/phpmyadmin4.1.14

#Apache寫法
Alias /phpmyadmin "d:/wamp/apps/phpmyadmin4.1.14/"

自己寫法

server {
listen       80;
server_name  localhost 127.0.0.1;
root   d:/localhost;
index  index.html index.htm index.php;
autoindex on; 
autoindex_exact_size off;
autoindex_localtime on;

location /phpmyadmin/ {
alias D:/wamp/apps/phpmyadmin4.1.14;
index index.php;
}

location ~ \.php$ {
try_files $uri =404;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index.php;
fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
include        fastcgi_params;    
}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
#

error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   html;
}

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

結果 訪問 http://localhost/phpmyadmin 提示 404 Not Found。

日誌資訊：

失敗，如何才可以實現nginx 的alias 指向phpmyadmin目錄（如果是所有的server一起指向更好）。

------解決思路----------------------
將phpmyadmin放在root 對應的根目錄下。
