我自己下载了phpMyAdmin，然后登录的时候会跳到根目录。要自己补回目录才能进去，网上查到有一个跟我一样的。他加了在config加了SCRIPT_FILENAME和SCRIPT_NAME就可以了，可是我已经是加了这些东西在fastcgi_params。

server {
listen 80;
server_name localhost;
root /home/wwwroot;
index index.html index.htm index.php;

# location /pma {
# index index.php;
# }
# location ~ ^/pma/.*\.(php|php5)$ {
# fastcgi_pass unix:/var/run/php5-fpm.sock;
# incl美国服务器ude fastcgi_params;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
# fastcgi_split_path_info ^(.+\.php)(.*)$;
# }

if (!-e $request_filename) {
rewrite ^/(.*)$ /index.php/$1 last;
break;
}

location ~ \.php
{
fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_split_path_info ^(.+\.php)(.*)$;
include fastcgi_params;
}
}

可能你用 localhost/phpmyadmin 访问的
试试 localhost/phpmyadmin/ (把后面反斜杠补全)
