haproxy配置基于ssl证书的https负载均衡

本实验全部在haproxy1.5.19版本进行测试通过,经过测试1.7.X及haproxy1.3版本以下haproxy配置参数可能不适用,需要注意版本号。

一、业务要求
现在根据业务的实际需要,有以下几种不同的需求。如下:

1.1 http跳转https

把所有请求http://www.chinasoft.com的地址全部跳转为https//:www.chinasoft.com这个地址

1.2 http与https并存

服务器同时开放http://www.chinasoft.com和https://www.chinasoft.com的访问形式

1.3 服务器环境准备

node1即haproxy所在服务器的处理

安装依赖
yum install -y openssl openssl-devel readline-devel pcre-devel libssl-dev libpcre3

# 下载安装包,
tar zxf haproxy-1.5.19.tar.gz
cd haproxy-1.5.19

useradd -u 188 -r -d /var/lib/haproxy -s /sbin/nologin haproxy
# 加入支持ssl的编译参数

make TARGET=linux2628 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 USE_CRYPT_H=1 USE_LIBCRYPT=1
make install PREFIX=/usr/local/haproxy
cp /usr/local/haproxy/sbin/haproxy /usr/sbin/
cp examples/haproxy.init /etc/init.d/haproxy

  chmod +x /etc/init.d/haproxy

  mkdir /etc/haproxy

  mkdir /var/lib/haproxy

# 修改启动脚本(可能会报错)为如下
vim /etc/init.d/haproxy
26 [[ ${NETWORKING} = "no" ]] && exit 0

后端web01(192.168.3.200)服务器apache配置,需要配置虚拟主机域名为:www.chinasoft.com否则无法正常处理

<VirtualHost *:8080>

</VirtualHost>

 

1.4 证书的处理,需要将网站的根证书和key简单的合并在一起:

cat chinasoft.com.pem chinasoft.com.key | tee chinasoft.pem

 

否则会报错
'bind *:443' : unable to load SSL private key from PEM file

1.5 域名的指向及处理
将www.chinasoft.com指向haproxy负载均衡器所在的服务器IP地址,此处是192.168.3.198

二、配置haproxy并测试业务需求
现在我们根据业务的需求,我们来配置haproxy一一达到其需求。

2.1 http跳转https配置

http跳转https的haproxy配置文件内容,如下:

[root@node1 haproxy]# cat /etc/haproxy/haproxy.cfg
global
log 127.0.0.1 local3 info
chroot /var/lib/haproxy
maxconn 4096
user haproxy
group haproxy
daemon
stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin
stats timeout 2m
tune.ssl.default-dh-param 2048

defaults
log global
mode http
option httplog
option dontlognull
option http-server-close
option forwardfor except 127.0.0.1
option redispatch
retries 3
option redispatch
maxconn 2000
timeout http-request 10s
timeout queue 1m
timeout connect 10s
timeout client 1m
timeout server 1m
timeout http-keep-alive 10s
timeout check 10s

listen admin_stats
bind 0.0.0.0:1080
mode http
option httplog
maxconn 10
stats refresh 30s
stats uri /haproxy?stats
stats auth admin:admin
stats hide-version

frontend weblb
bind *:80
acl is_http hdr_beg(host) www.chinasoft.com
redirect scheme https if !{ ssl_fc }
bind *:443 ssl crt /etc/haproxy/chinasoft.pem
use_backend httpserver if is_http

backend httpserver
balance source
server web1 192.168.3.200:8080 maxconn 1024 weight 3 check inter 2000 rise 2 fall 3

 

# 配置好之后先检查语法是否正确
[root@node1 haproxy]# /etc/init.d/haproxy check
Configuration file is valid

在以上配置文件中,需要注意的选项如下:

tune.ssl.default-dh-param 2048因为我们的SSL密钥使用的是2048bit加密,所以在此进行声明。
acl is_http hdr_beg(host) www.chinasoft.com
redirect scheme https if !{ ssl_fc }
bind *:443 ssl crt /etc/haproxy/chinasoft.pem

这三行表示把所有访问www.chinasoft.com这个域名的请求,全部转发到https://www.chinasoft.com这个连接

管理页面

2.2 测试http跳转https

http跳转https配置完毕后,我们选择来测试其跳转。如下:

你会发现在浏览器中,无论你输入的是www.chinasoft.com,还是http://www.chinasoft.com亦或是https://www.chinasoft.com,都会自动跳转到https://www.chinasoft.com。

这样就达到了,把所有的http请求跳转到https的目的。


2.3 http与https并存配置
haproxy要实现http和https并存的话,配置也很简单,只需要把haproxy分别监控不同的端口就行,配置文件如下:

[root@node1 haproxy]# cat haproxy.cfg
global
log 127.0.0.1 local3 info
chroot /var/lib/haproxy
maxconn 4096
user haproxy
group haproxy
daemon
stats socket /var/lib/haproxy/haproxy.sock mode 600 level admin
stats timeout 2m
tune.ssl.default-dh-param 2048

defaults
log global
mode http
option httplog
option dontlognull
option redispatch
retries 3
option redispatch
maxconn 2000
timeout connect 10s
timeout client 1m
timeout server 1m
timeout check 10s

listen admin_stats
bind 0.0.0.0:1080
mode http
option httplog
maxconn 10
stats refresh 30s
stats uri /haproxy?stats
stats auth admin:admin
stats hide-version

frontend weblb
bind *:80
acl is_http hdr_beg(host) www.chinasoft.com
use_backend httpserver if is_http

backend httpserver
balance source
server web1 192.168.3.200:8080 maxconn 1024 weight 3 check inter 2000 rise 2 fall 3

frontend weblb443
bind *:443 ssl crt /etc/haproxy/chinasoft.pem
acl is_443 hdr_beg(host) www.chinasoft.com
use_backend httpserver443 if is_443

backend httpserver443
balance source
server web1 192.168.3.200:8080 maxconn 1024 weight 3 check inter 2000 rise 2 fall 3

 

在以上配置文件中,我们定义了两个前端,一个前端用于监听80端口,也就是http协议。另外一个前端监听443端口,也就是https协议。

此时haproxy会根据客户端请求的协议进行分发,如果发现客户端请求的是http协议,则把该请求分发到监听80端口的前端。如果发现客户端请求的是https协议,则把该请求分发到监听443端口的前端。如此就达到了haproxy让http和https并存的要求。

2.4 测试http与https并存
http与https并存配置完毕后,我们选择来测试其跳转。如下:

 

通过测试你会发现,在浏览器中如果你输入的是http://www.chinasoft.com或者是www.chinasoft.com都会直接跳转到http://www.chinasoft.com,而输入的是https://www.chinasoft.com,则只会跳转到https://www.chinasoft.com。

如此就到达了,我们业务的要求实现http和https并存。
