3.4.1.	405 Not Allowed?
	靜態頁面POST會提示405 Not Allowed錯誤. # curl -d name=neo http://www.mydoamin.com/index.html <html> <head><title>405 Not Allowed</title></head> <body bgcolor="white"> <center><h1>405 Not Allowed</h1></center> <hr><center>nginx</center> </body> </html> server { listen 80 default; server_name myid.mydomain.com; charset utf-8; access_log /var/log/nginx/myid.mydomain.com.access.log main; if ($http_user_agent ~* ^$){ return 412; } ########################### location / { root /www/mydomain.com/myid.mydomain.com; index index.html index.php; #error_page 405 =200 $request_filename; } #error_page 404 /404.html; # error_page 405 =200 @405; location @405 { #proxy_set_header Host $host; proxy_method GET; proxy_pass http://myid.mydomain.com; } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/html; } }
3.4.2.	nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except" block in /etc/nginx/conf.d/info.mydomain.com.conf:112? nginx: configuration file /etc/nginx/nginx.conf test failed
	使用$request_uri變數可以解決上述問題. if ( $request_uri ~ "^/\w+\.xml$") { proxy_pass http://www.mydomain.com/xml$request_uri; break; } if ( $request_uri ~ "^/public/datas/\w+\.xml$") { proxy_pass http://www.mydomain.com/$request_uri; break; }
3.4.3.	502 Bad Gateway error.log 提示： upstream sent too big header while reading response header from upstream?
	修改fastcgi配置 location ~ \.php$ { fastcgi_buffers 8 16k; fastcgi_buffer_size 32k; 。。。。。。 }

3.4.1. proxy_pass

nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except" block in /etc/nginx/conf.d/www.mydomain.com.conf:25
nginx: configuration file /etc/nginx/nginx.conf test failed

在location,if中使用證則匹配proxy_pass末尾不能寫/

	if ($request_uri ~* "^/info/{cn|tw}/{news|info}/\d\.html") {
		proxy_pass http://info.example.com/;
		break;
	}

    location ~ ^/info/ {
                proxy_pass http://info.example.com/;
                break;
    }

proxy_pass http://info.example.com/; 改為 proxy_pass http://info.example.com; 可以解決
