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;

  10.             if ( !-e $request_filename){

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

  12.                 break;

  13.             }

  14.         }

  17.         location ^~ /.git {

  18.             return 403;

  32.         }

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

  35.             try_files $uri =404;

  36.             fastcgi_pass  127.0.0.1:9000;
