Haproxy实现多域名证书HTTPS
前面讲到，使用Nginx实现多域名证书HTTPS(http://fengwan.blog.运维网.com/508652/1719708),通过重新编译Nginx实现TLS SNI Support打开，那么使用Haproxy如何实现呢？要求：
Haproxy必须要1.5以上的版本
第一步：openssl的安装
tar zxf openssl-0.9.8zh.tar.gz
cd openssl-0.9.8zh
./config enable-tlsext --prefix=/usr/local/opensslno-shared
make && make install_sw
#以上安装不影响系统中的openssl版本，主要就是打开openssl的TLS SNI功能 第二步:Haproxy的安装
tar zxf haproxy-1.5.15.tar.gz
cd haproxy-1.5.15
make TARGET=linux26 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 ARCH=x86_64 PREFIX=/usr/local/haproxy1.5.15 SSL_INC=/usr/local/openssl/include SSL_LIB=/usr/local/openssl/lib ADDLIB=-ldl
make TARGET=linux26 USE_PCRE=1 USE_OPENSSL=1 USE_ZLIB=1 ARCH=x86_64 PREFIX=/usr/local/haproxy1.5.15 SSL_INC=/usr/local/openssl/include SSL_LIB=/usr/local/openssl/lib ADDLIB=-ldl install
#记得上面要指定openssl的地址，haproxy没有config这步 第三步：生成证书
# mkdir ~/keys
# cd ~/keys
# openssl genrsa -out passport.abc.com.key 2048
# openssl req -new -key passport.abc.com.key -out passport.abc.com.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) :CN #国家
State or Province Name (full name) :GuangDong#省份
Locality Name (eg, city) :ShenZhen #城市
Organization Name (eg, company) :Test.Inc #公司名称
Organizational Unit Name (eg, section) []:passport.abc.com #组织名称
Common Name (eg, your name or your server's hostname) []:passport.abc.com #域名
Email Address []:passport@abc.com
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
# openssl x509 -req -days 3650 -in passport.abc.com.csr -signkey passport.abc.com.key -out passport.abc.com.crt
# cat passport.abc.com.crt passport.abc.com.key |tee passport.abc.com.pem 按照以上方法依次生成www.test.com admin.abc.com的证书文件，每个站点最后会有一个pem文件生成
配置Haproxy的配置文件:
frontend http_server
bind :80
bind :443 ssl crt /etc/haproxy/keys/www.test.com.pem crt /etc/haproxy/keys/admin.test.com.pem crt /etc/haproxy/keys/passport.abc.com.pem
#按照如上规则如果多个站点就可以使用同样的规则 bind :443 ssl crt $filepath crt $file2path crt $file3path
mode http
acl sslhdr_reg(host) -i ^(www.test.com|admin.test.com|passport.abc.com)$
redirect scheme https code 301 if !{ ssl_fc }ssl
#对以上站点进行https跳转
#在某些情况下，在特定页面需要进行跳转，则
acl ssl_site hdr_reg(host) -i ^(
acl ssl_path path_beg -i /Login /Pay/Pay.aspx
redirect scheme https code 301 if !{ ssl_fc }ssl_site ssl_path
redirect scheme http code 301 if { ssl_fc }ssl_site !ssl_path
#只在/loign /Pay/Pay.aspx页面进行跳转，其他页面使用http
acl wwwtest_com hdr_reg(host) -i ^(www.test.com)$
use_backend www_test_com if wwwtest_com { ssl_fc_sni www.test.com }
#这里就是证书的对应部分，如
acl admintest_com hdr_dom(host) -i admin.test.com
use_backend admin_test_com if admintest_com { ssl_fc_sni admin.test.com }
acl passportabc_com hdr_dom(host) -i passport.abc.com
use_backend pasport_abc_com if passport_abc_com { ssl_fc_sni passport.abc.com }
backend www_test_com
server test2 192.168.10.2:80 check port 80 inter 5000 rise 2 fall 3 weight 1
backend admin_test_com
server test4 192.168.10.4:80 check port 80 inter 5000 rise 2 fall 3 weight 1
backend passport_abc_com
server test5 192.168.10.5:80 check port 80 inter 5000 rise 2 fall 3 weight 1 按照以上配置就可以实现多证书的HTTPS，依次访问上面的访问会发现，相关的证书与之配对。
