haproxy nginx tomcat

マシンにhaproxy nginx tomcatを搭載したアーキテクチャモデル
 
haproxyがない場合nginxリスニング80ポートはダイナミックリクエストをバックエンドの8080に転送する
 
 
 
 
haproxyがある後haproxyリスニング80はnginxの8001 nginxに転送して動的な要求を話してtomcatの8080に転送します
 
 
しかし、要求されたurlの後ろに8001ポートが含まれているという問題があります.
 
 
最後に解決策を見つけた
 
nginxでconf
 

server {
          listen       8001;
          server_name  beta.google.com;
        

location / {
             proxy_pass http://tomcat;

                   proxy_redirect off;
                   proxy_set_header Host $host;
                   proxy_set_header X-Real-IP $remote_addr;
                   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

 
 
これで8001はありません
 
haproxy.conf

listen lbserver  *:80
   cookie JSESSIONID prefix
  # - equal weights on all servers
  # - maxconn will queue requests at HAProxy if limit is reached
  # - minconn dynamically scales the connection concurrency (bound my maxconn) depending on size of HAProxy queue
  # - check health every 20000 microseconds
 option httpchk GET /index
  server nginx1  127.0.0.1:8001  weight 1 minconn 3 maxconn 6 check inter 20000
  server tomcat2  127.0.0.1:8082  weight 1 minconn 3 maxconn 6 check inter 20000

 
 
 
その後8001がまた現れました
一つ配られたので
rewrite/mmm /fff  permanent;
 
これで転送後にまた8001が現れた
 
解決策
 
rewrite/mmm  http://beta.google.cn/fff  permanent;
 
 
現象を見るとnginx内部転送すると、あなたが何のポートから来たのか、何のポート8001に転送されたのか、自然に8001に転送されます.
でも外から来たら80来ます

Hi, everyone.

I have a server running a php web forum. User logging into my site
using 'logging.php'.

I had set up a https server using nginx, but consdering server load, I
just want my user using https in only logging.php.

I want to settle this by using url rewrite. When my users click
http://mysite.com/logging.php,
 nginx will automatic change the url to
https://mysite.com/logging.php
. And when my user click any other links
in my site, for example, https://mysite.com/index.php,
 nginx will
change https to http.

Can rewrite work like this?

Thank you!

BTW,changing my forum codes may work, but I didn't know much about php
coding...so, I want to settle this in nginx rewrite...

In your plain http server block:

if ($uri ~* "/logging.php$") {
 rewrite ^/(.*)$ https://$host/$1
 redirect;
}


In your https server block

if ($uri !~* "/logging.php$") {
 rewrite ^/(.*)$ http://$host/$1
 redirect;
}


This is when you are using standard ports (80 for HTTP and 443 for 
HTTPS). If you are using non-standard ports (say 8080 for http, and 8443 
for https, then in this case, you should have in your http block)

if ($uri ~* "/logging.php$") {
 rewrite ^/(.*)$ https://$host:8443/$1
 redirect;
}

and correspondingly, in your https block, you should have:

if ($uri !~* "/logging.php$") {
 rewrite ^/(.*)$ http://$host:8080/$1
 redirect;
}

The $host variable is the host portion of the URL that was used to reach 
your server
