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,并且后面有两个基于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),但它一直说错误404未找到.我错过了一些明显的东西吗？

Answer 1

这里的问题是只按location顺序获取"最佳" 指令:

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$" location指令打败,因此前者将被完全忽略.此外,您的php fastcgi指令已硬连接到您的/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;
}

Answer 2

直接设置'root'.更少的指令,更少的计算需要设置更多的变量.还有其他一些东西(如fastcgi_param DOCUMENT_ROOT)在当前接受的答案中无法正确设置.这个方法将处理所有这些:

location ~ \.php$ {
    if ($request_uri ~* /phpmyadmin) {
        root /var/www/nginx-default/phpMyAdmin;
    }

    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    include /etc/nginx/fastcgi_params;
}
