Solve nginx error message: rewrite or internal redirection cycle while internally redirecting to "/",

Configure nginx+php-fpm, visit the homepage, and an error message appears:

2015/01/14 23:04:39 [error] 10964#2788: *2 rewrite or internal redirection cycle while internally redirecting to "/", client : 127.0.0.1, server: bk, request: "GET / HTTP/1.1", host: "bk"

Error reason: caused by index command, the solution is to change try_files $uri $uri/; to try_files $uri $uri / =404;

Special note: There cannot be any space between the equal sign of =404 and 404.

Complete configuration: bk.conf source code is as follows (if you need to reprint, please mark the original author default.fu@foxmail.com):

server {
	listen       80;
	server_name  bk;
	root d:/website/bk.com/www;
	index index.html index.htm index.php;
	
	location / {				
		try_files $uri $uri/ =404;
	}
	
	location ~ \.php$ {
		fastcgi_pass   127.0.0.1:9000;
		fastcgi_index  index.php;
		fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
		include        fastcgi_params;    
		try_files $uri =404;
	}
	

	#error_page  404              /404.html;

	# redirect server error pages to the static page /50x.html
	#
	
	error_page   500 502 503 504  /50x.html;
	#location = /50x.html {
	#	root   html;
	#}
	
	location ~ /\.(ht|svn|git) {
		deny all;
	}
}
