  3.              server 192.168.6.119:9090;

  4.              server 192.168.6.119:8090;

  5.          }

  6. server {

  7.         listen 80;

  8.         server_name proxy.test.com;

  9.         location / {

  10.           proxy_set_header Host $host;

  11.           proxy_set_header X-Real-IP $remote_addr;

  12.           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

  13.  

  14.              #禁用缓存

  15.              proxy_buffering off;

  16.  

  17.              #反向代理的地址

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

  19.         }

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

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. server {

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

  8.     

  9.         server_name oc.haodai.com;

  10.         ssl on;

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

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

  13.         location / {

  14.                 proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;

  15.                 proxy_set_header Host $host;

  16.                 proxy_set_header X-Real-IP $remote_addr;

  17.                 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

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

  19.                 proxy_pass http://oc_haodai_com;

  20.         }

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

  22. }

  23. server {

  24.         listen 80;

  25.         server_name oc.haodai.com;

  26.         location / {

  27.                 proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;

  28.                 proxy_set_header Host $host;

  29.                 proxy_set_header X-Real-IP $remote_addr;
