Nginx 位置指令似乎不起作用。我错过了什么吗？

Question

我已经将 Nginx 设置为我的主要 Web 服务器，并在其后面有两个基于 Mochiweb 的服务器。某些请求被反向代理到这两个服务器。现在，我想使用nginx访问phpmyadmin(位于/var/www/nginx-default/phpMyAdmin)，但它一直显示错误404未找到。我在这里遗漏了一些明显的东西吗？

这里的问题是，只有“最佳”location 指令被采用，按以下顺序:

location =  <path>  (longest match wins)
location ^~ <path>  (longest match wins)
location ~  <path>  (first defined match wins)
location    <path>  (longest match wins)

使用此规则集，您的 /phpmyadmin location 指令将被正则表达式“.php$”击败location 指令，因此前者被完全忽略。此外，您的 php fastcgi 指令硬连接到您的 /home/me/dev 目录，这意味着 phpMyAdmin 完全无法访问。您可以使用重写来获取 phpMyAdmin 脚本的正确根目录:

location ~ \.php$ {
    set $php_root /home/me/dev;
    if ($request_uri ~* /phpmyadmin) {
        set $php_root /var/www/nginx-default/phpMyAdmin;
    }

    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $php_root$fastcgi_script_name;
    include /etc/nginx/fastcgi_params;
}
