nginx反向代理与负载均衡

1. upstream proxy.test.com {

3.              #ip_hash;

5.              server 192.168.6.119:9090;

7.              server 192.168.6.119:8090;

10.          }

14. server {

15.         listen 80;

16.         server_name proxy.test.com;

17.         location / {

18.           proxy_set_header Host $host;

20.           proxy_set_header X-Real-IP $remote_addr;

22.           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

24.  

26.              #禁用缓存

28.              proxy_buffering off;

30.  

32.              #反向代理的地址

34.              proxy_pass http://proxy.test.com;

35.         }

37.     }

[root@node3 vhost]# curl proxy.test.com
119
[root@node3 vhost]# curl proxy.test.com
nginx2
[root@node3 vhost]# curl proxy.test.com
119
[root@node3 vhost]# curl proxy.test.com
nginx2

线上某机器举例：反向代理和负载均衡

1. upstream oc_haodai_com {

2.         server 192.168.1.37:8080 weight=2 max_fails=2 fail_timeout=30s;

3.       # server 192.168.1.38:8080 weight=2 max_fails=2 fail_timeout=30s;

4.       #server 192.168.1.39:8080 weight=2 max_fails=2 fail_timeout=30s;

5. }

7. server {

8.         listen 443;    ###https的默认端口  http是80

9.     

10.         server_name oc.haodai.com;

11.         ssl on;

12.          ssl_certificate /usr/local/nginx1.8/conf/haodai.com.crt;

13.          ssl_certificate_key /usr/local/nginx1.8/conf/haodai.com.key;

14.         location / {

15.                 proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;

16.                 proxy_set_header Host $host;

17.                 proxy_set_header X-Real-IP $remote_addr;

18.                 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

19.                 #session_sticky_hide_cookie upstream=account.free4lab.com;

20.                 proxy_pass http://oc_haodai_com;

21.         }

23.     access_log /home/wwwlogs/oc.haodai.com.proxy.log access;

24. }

29. server {

30.         listen 80;

32.         server_name oc.haodai.com;

33.         location / {

34.                 proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;

35.                 proxy_set_header Host $host;

36.                 proxy_set_header X-Real-IP $remote_addr;

37.                 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

38.                 #session_sticky_hide_cookie upstream=account.free4lab.com;

39.                 proxy_pass http://oc_haodai_com;

40.         }

42. }

37.38.39上配置文件

1. [root@order_web04 vhost]# more oc.haodai.com.conf

2. server {

3.         listen       8080;

4.         server_name  oc.haodai.com;

5.         index index.html index.htm index.php;

6.         root  /home/wwwroot/order_center;

8.         location / {

9.             index index.php;

10.             if ( !-e $request_filename){

11.                 rewrite ^/(.*)$ /index.php?s=$1 last;

12.                 break;

13.             }

14.         }

17.         location ^~ /.git {

18.             return 403;

19.         }

22.         location ~ /Common/sh/.*\.(php|php5|sh|py|pl)$ {

30.         if ($request_uri ~* "/Common/sh") {

31.                 return 403;

32.         }

34.         location ~ .*\.(php|php5)?$ {

35.             try_files $uri =404;

36.             fastcgi_pass  127.0.0.1:9000;

42.         if ( $fastcgi_script_name ~ \..*\/.*php ) {

43.             return 403;
