Question

安装

apt-get install munin
apt-get install spawn-fcgi
spawn-fcgi -s /var/run/munin/fcgi-graph.sock -U www-data -u munin -g munin /usr/lib/munin/cgi/munin-cgi-graph

nginx

server {
    listen  80;
    server_name  munin.dynaccount.com;

    root  /var/cache/munin/www;

    location / {
        try_files  $uri $uri/ =404;
    }

    location ^~ /munin-cgi/munin-cgi-graph/ {
        fastcgi_split_path_info  ^(/munin-cgi/munin-cgi-graph)(.*);
        fastcgi_param PATH_INFO  $fastcgi_path_info;
        fastcgi_pass  unix:/var/run/munin/fcgi-graph.sock;
        include  fastcgi_params;
    }
}

我在我的 ubuntu 服务器上遇到了同样的问题。我试过这个https://serverfault.com/a/713408但没有任何反应，然后我删除了

/var/run/munin/fcgi-graph.sock

并再次运行：

spawn-fcgi -s /var/run/munin/fcgi-graph.sock -U www-data -u www-data -g www-data /usr/lib/munin/cgi/munin-cgi-graph

之后一切正常。
