问nginx+php5.3.3+phpmyadmin总是返回500？

各位大侠，我的服务器总是走不通，单独访问其他php文件就行，访问index就是500，不知道为什么？能给我点指点吗？http://119.29.84.51:8080/test.php 这样可以访问http://119.29.84.51:8080/index.php 这样不行我这里配置是指向phpMyAdmin配置如下，应该没什么问题server { listen 8080; server_name localhost; # server_name 119.29.84.51; #charset koi8-r; root /mydata/web/phpMyAdmin; access_log /mydata/web/host.access.log main; # Load configuration files for the default server block. # include /etc/nginx/default.d/.conf; location / { root /mydata/web/phpMyAdmin;#This dir to //usr/share/nginx/html index index.php index.html index.htm;# if (-f $request_filename) {# expires max;# break;# } } error_page 404 /404.html; location = /404.html { root /usr/share/nginx/html; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 location ~ .php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_split_path_info ^(.+.php)(.)$; fastcgi_param PATH_INFO $fastcgi_path_info; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # #location ~ .php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # # location ~ .php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; # include fastcgi_params; #} 不知道是否php有些函数功能没开放什么的原因没有？
