29.frontend test.com #定义前端服务器(haproxy)
30. bind *:80 #监听地址
31. acl web-client path_beg -i /vsphere-client
32. acl bbs hdr_reg(host) -i ^(bbs.test.com|shequ.test.com|forum)
33. acl monitor hdr_beg(host) -i monitor.test.com #定义ACL名称,对应的请求的主机头是monitor.test.com
34. acl www hdr_beg(host) -i www.test.com
35. use_backend cache.test.com if static
36. use_backend monitor.test.com if bbs or monitor
37. use_backend www.test.com if www
38. use_backend vsphere-client if web-client
39.
40. default_backend www.test.com #指定默认的后端服务器
41.
42.
43.backend monitor.test.com #定义后端服务器群(web server/apache/nginx/iis..)
44. mode http
45. option forwardfor #后端服务器(apache/nginx/iis/*),从Http Header中获得客户端IP
46. balance leastconn #负载均衡的方式,最小连接
47. cookie SERVERID #插入serverid到cookie中,serverid后面可以定义
48. option httpchk HEAD /check.html #用来做健康检查html文档
49. #option httpchk HEAD /index.php HTTP/1.1\r\nHost:monitor.test.com #HTTP && Host
50. server server1 10.0.100.70:80 cookie server1 check inter 2000 rise 3 fall 3 weight 3
51. #服务器定义:
52. #cookie server1表示serverid为server1;
53. #check inter 2000 是检测心跳频率(check 默认 );
54. #rise 3 表示 3次正确认为服务器可用;
55. #fall 3 表示 3次失败认为服务器不可用;
56. #weight 表示权重。

85. stats auth admin:admin #统计页面用户名和密码设置
86. stats hide-version #隐藏统计页面上HAProxy的版本信息
87. stats admin if TRUE #手工启用/禁用,后端服务器
2 其它acl 规则
1. ###########acl 开始了############
2. acl bbs hdr_reg(host) -i ^(bbs.test.com|forum.test.com) #使用正则匹配
3. acl bbs_path path_beg -i /bbs #url 目录
4. acl youxi path_beg -i /youxi
5. acl static path_end -i .html .css .js #url 结尾文件
6. acl php path_end -i .php
7. acl jsp path_end -i .jsp .do
8.
9. use_backend bbs_pool if bbs or bbs_path #注意 "or"
10.use_backend youxi_pool if youxi
11.use_backend static_pool if static
12.use_backend php_pool if php
13.use_backend jsp_pool if jsp
14.default_backend www.test.com
15.###########acl 结束了############
#acl 参数
acl(关键字) 定义acl(名称) 方法 -i (忽略大小写) [匹配的路径或文件]
hdr_beg(host)
hdr_reg(host)
path_beg
path_end
3 use_backend 参数
1. or 用于匹配多个acl 名称
2. default_backend 没有满足条件的时候使用默认的后端服务器
#20120610
haproxy 重定向url (301)
1. acl web-client path_beg -i /vsphere-client
2.
3. use_backend vsphere-client if web-client
4.
5. backend vsphere-client
6. mode http
7. option forwardfor header ORIG_CLIENT_IP
8. balance roundrobin
9. option httpchk HEAD /check.html
10. server server1 10.0.100.81:80 redir https://192.168.57.81:443 check inter 2000 rise 3 fall 3 weight 3
