FastCGI

发布于 2014年10月15日

Nginx 莫名不能用了，直接无法解析 php 文件，打开就空白。不会是配置出错，因为之前一直没问题，可能是最近更新软件升级了 nginx 或是 php-cgi / php-fpm（不确定），然后就不能用了。翻 log 说的是 FastCGI 这个出错，

[error] 7132#0: *3 connect() failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: www.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "www.com"
[error] 7165#0: *10 upstream sent unsupported FastCGI protocol version: 60 while reading response header from upstream, client: 127.0.0.1, server: www.com, request: “GET / HTTP/1.1”, upstream: “fastcgi://127.0.0.1:80”, host: “www.com”

[error] 7832#0: *83 FastCGI sent in stderr: “Primary script unknown” while reading response header from upstream, client: 127.0.0.1, server: www.com, request: “GET /test.php HTTP/1.1”, upstream: “fastcgi://unix:/var/run/php5-fpm.sock:”, host: “www.com”

改了好几次，确定是 site 配置问题，关键是以前能用现在不能了。真是莫名其妙。

把 nginx 默认的配置

	#location ~ \.php$ {
	#	fastcgi_split_path_info ^(.+\.php)(/.+)$;
	#	# NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
	#
	#	# With php5-cgi alone:
	#	fastcgi_pass 127.0.0.1:9000;
	#	# With php5-fpm:
	#	fastcgi_pass unix:/var/run/php5-fpm.sock;
	#	fastcgi_index index.php;
	#	include fastcgi_params;
	#}

最下面

include fastcgi_params;

下再加上一行

fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;

然后就好了。。。话说 nginx 里边都没这个。。
