Nginx 位置指令似乎不起作用.我错过了什么吗? [英] Nginx location directive doesn't seem to be working. Am I missing something?

问题描述

我已将 Nginx 设置为我的主要 Web 服务器，并在其背后有两个基于 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)，但它一直说找不到错误 404.我在这里遗漏了一些明显的东西吗?

I've set up Nginx as my main web server and have two Mochiweb based servers behind it. Certain requests are reverse-proxied to these two servers. now, I want to access phpmyadmin (located at /var/www/nginx-default/phpMyAdmin) using nginx, but it keeps saying Error 404 not found. Am I missing something obvious here?

推荐答案

这里的问题是只有最佳"location 指令被采用，顺序如下:

The problem here is that only the "best" location directive gets taken, in this order:

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 指令被正则表达式.php$"location<击败/code> 指令，所以前者被完全忽略.此外，您的 php fastcgi 指令硬连接到您的 /home/me/dev 目录，这意味着 phpMyAdmin 是完全无法访问的.您可以使用重写为您的 phpMyAdmin 脚本获取正确的根目录:

Using this ruleset, your /phpmyadmin location directive is beaten out by the regular expression ".php$" location directive, so the former is ignored entirely. Additionally, your php fastcgi directive is hard-wired to your /home/me/dev directory, which means that phpMyAdmin is totally inaccessible. You can use a rewrite to get the correct root for your phpMyAdmin scripts:

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;
}
