这样就生成了下面的三个文件：
[root@ha02 haproxy-1.4.26]# tree /etc/ssl/xip.io/ /etc/ssl/xip.io/ ├── xip.io.crt ├── xip.io.csr └── xip.io.key 0 directories, 3 files
在创建了证书之后，我们需要创建pem文件。pem文件本质上只是将证书 密钥及证书中心证书（可有可无）拼接成一个文件。在我们在这里只是简单地将证书及密钥文以这个顺序拼接在起来创建xip.io.pen文件 。这就是HAProxy读取SSL证书首选的方式。
[root@ha02 haproxy-1.4.26]# cat /etc/ssl/xip.io/xip.io.crt /etc/ssl/xip.io/xip.io.key |tree /etc/ssl/xip.io/xip.io.pem /etc/ssl/xip.io/xip.io.pem [error opening dir] 0 directories, 0 files [root@ha02 haproxy-1.4.26]# ls /etc/ssl/xip.io/ xip.io.crt xip.io.csr xip.io.key 有报错，并没有生成.pem结尾的文件
后来细心看一下一个命命看错了应该是tee而不是tree

当购买真正的证书时，你不一定会获取并接后的文件。可能需要自己拼接生成，但也有机构提供拼接好的文件 给你。但可能不是pem文件，而是dundel ，cert， cert， key文件或一些相同概念但名称类似的文件。
pem文件是HAProxy只需简单配置就可以处理SSLL连接了。
要在HAProxy使用SSL连接 ，我们现在就可以添加校准SSL端口443的绑定，并让HAProxy知道SSL证书的位置 ：
stats admin if TRUE | stats admin if TRUE mode http | mode http #server sshd 192.168.1.104:22 check port 22 inter | #server sshd 192.168.1.104:22 check port 22 inter | frontend app01_www.app01.com:8010 | frontend app01_www.app01.com:8010 bind *:8010 | bind *:8010 bind *:443 ssl crt /etc/ssl/xip.io/xip.io.pem | --------------------------------------------------------- timeout client 8h | timeout client 8h mode http | mode http default_backend server_app01 | default_backend server_app01 backend server_app01 | backend server_app01 mode http | mode http timeout server 8h | timeout server 8h cookie SERVERID insert nocache | cookie SERVERID insert nocache server app01 10.100.0.37:8010 check port 8010 rise| server app01 10.100.0.37:8010 check port 8010 ris frontend app02_www.app02.com:8020 | frontend app02_www.app02.com:8020 bind *:8020 | bind *:8020 bind *:443 ssl crt /etc/ssl/xip.io/xip.io.pem | --------------------------------------------------------- timeout client 8h | timeout client 8h mode http | mode http default_backend server_app02 | default_backend server_app02 backend server_app02 | backend server_app02 mode http | mode http timeout server 8h | timeout server 8h + +-- 2 lines: cookie SERVERID insert nocache--------------|+ +-- 2 lines: cookie SERVERID insert nocache-------------
看看下在的改动只是加了一行代码：
bind *:443 ssl crt /etc/ssl/xip.io/xip.io.pem
上面的配置可以支持https也支持http
下面只支持https,看一下这三个文件的不同：

前左边的只支持https右边是支持https和http
