nginx反向代理与负载均衡

1. upstream proxy.test.com {
   

2. 
   

3.              #ip_hash;
   

4. 
   

5.              server 192.168.6.119:9090;
   

6. 
   

7.              server 192.168.6.119:8090;
   

8. 
   

9. 
   

10.          }
    

11. 
    

12. 
    

13. 
    

14. server {
    

15.         listen 80;
    

16.         server_name proxy.test.com;
    

17.         location / {
    

18.           proxy_set_header Host $host;
    

19. 
    

20.           proxy_set_header X-Real-IP $remote_addr;
    

21. 
    

22.           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    

23. 
    

24.  
    

25. 
    

26.              #禁用缓存
    

27. 
    

28.              proxy_buffering off;
    

29. 
    

30.  
    

31. 
    

32.              #反向代理的地址
    

33. 
    

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

35.         }
    

36. 
    

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. }
   

6. 
   

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.         }
    

22. 
    

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

24. }
    

25. 
    

26. 
    

27. 
    

28. 
    

29. server {
    

30.         listen 80;
    

31. 
    

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.         }
    

41. 
    

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;

10.             if ( !-e $request_filename){
    

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

12.                 break;
    

13.             }
    

14.         }
    

15. 
    

16. 
    

17.         location ^~ /.git {
    

18.             return 403;
    

19.         }
    

20. 
    

21. 
    

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

23.             deny all;

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

43.             return 403;
