配置HTTPS

環境為CentOS 7.3、httpd2.4.6

一 搭建證書

CA 主機為192.168.29.3

client主機為 192.168.29.100

1 生成私鑰

[root@centos7 ~]# (umask 077 ; openssl genrsa -out /etc/pki/CA/private/cakey.pem 4096)
Generating RSA private key, 4096 bit long modulus
.....................++
...........................................................................................................................................................................................++
e is 65537 (0x10001)

2 生成自簽證書

[root@centos7 ~]# openssl req -new -x509 -key /etc/pki/CA/private/cakey.pem -out /etc/pki/CA/cacert.pem -days 365
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) [XX]:CN
State or Province Name (full name) []:BeiJing
Locality Name (eg, city) [Default City]:BeiJing
Organization Name (eg, company) [Default Company Ltd]:Company
Organizational Unit Name (eg, section) []:OPS
Common Name (eg, your name or your server's hostname) []:www.test.com
Email Address []:
[root@centos7 ~]#

3 為CA提供所需的目錄及文件

（1）所需目錄，如果無，則創建

/etc/pki/CA/certs/

/etc/pki/CA/crl/

/etc/pki/CA/newcerts/

（2）所需文件

[root@centos7 ~]# touch /etc/pki/CA/serial #序列號文件

[root@centos7 ~]# touch /etc/pki/CA/index.txt #數據庫文件

（3）

[root@centos7 ~]# echo 01 > /etc/pki/CA/serial #維護ca的序列號

4 在client上進行如下操作

（1）創建放置公鑰私鑰的文件夾

[root@CentOS7 ~]# mkdir /etc/httpd/ssl

（2）生成自己的私鑰

[root@CentOS7 ~]# (umask 077; openssl genrsa -out /etc/httpd/ssl/httpd.key 2048)

Generating RSA private key, 2048 bit long modulus

…………………………………+++

……………………………..+++

e is 65537 (0x10001)

[root@CentOS7 ~]#

（3）請CA為自己生成公鑰

[root@CentOS7 ~]# openssl req -new -key /etc/httpd/ssl/httpd.key -out /etc/httpd/ssl/httpd.csr -days 365
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.

-----
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:BeiJing
Locality Name (eg, city) [Default City]:BeiJing
Organization Name (eg, company) [Default Company Ltd]:Company
Organizational Unit Name (eg, section) []:OPS
Common Name (eg, your name or your server's hostname) []:www.test.com
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

（4）把生成的公鑰發送給CA

[root@CentOS7 ~]# scp /etc/httpd/ssl/httpd.csr root@192.168.29.3:/tmp/
The authenticity of host '192.168.29.3 (192.168.29.3)' can't be established.
ECDSA key fingerprint is f2:2e:89:a2:8d:22:22:9c:a9:f8:c9:19:18:d3:b6:c4.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.29.3' (ECDSA) to the list of known hosts.
root@192.168.29.3's password:
httpd.csr 100% 1005 1.0KB/s 00:00

5 在CA主機上為client簽證

[root@centos7 ~]# openssl ca -in /tmp/httpd.csr -out /etc/pki/CA/certs/httpd.crt -days 365
Using configuration from /etc/pki/tls/openssl.cnf
Check that the request matches the signature
Signature ok

6 把簽署的證書發給client

[root@centos7 ~]# scp /etc/pki/CA/certs/httpd.crt root@192.168.29.100:/etc/httpd/ssl/
The authenticity of host '192.168.29.100 (192.168.29.100)' can't be established.
ECDSA key fingerprint is 32:16:f3:2d:78:65:9f:a0:31:6c:dc:b9:24:e7:5a:8f.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.29.100' (ECDSA) to the list of known hosts.
root@192.168.29.100's password:
httpd.crt 100% 5711 5.6KB/s 00:00

二 HTTPS配置

7 安裝mod_ssl模塊

[root@CentOS7 ~]# yum install mod_ssl -y

8 修改配置文件/etc/httpd/conf.d/ssl.conf

DocumentRoot "/data/https"
ServerName www.test.com:443
<Directory "data/https">
AllowOverride None
Require all granted
</Directory>
SSLCertificateFile /etc/httpd/ssl/httpd.crt

SSLCertificateKeyFile /etc/httpd/ssl/httpd.crt

注意：

并修該/etc/httpd/ssl/httpd.crt、/etc/httpd/ssl/httpd.crt兩個文件的屬性，確保apach為可讀就行，當然也可放在默認文件夾下，就不需要修改權限了。

[root@CentOS7 ~]#chmod +r /etc/httpd/ssl/httpd.key

9 檢查語法

[root@CentOS7 ~]# httpd -t

Syntax OK

10 修給默認頁面

[root@CentOS7 ~]# echo “www.test.com” > /data/https/index.html

11 啟動http服務

[root@CentOS7 ~]# systemctl start httpd.service

12 把CA 的自簽證書傳到桌面

[root@centos7 ~]# sz /etc/pki/CA/cacert.pem

改名為cacert.crt

雙擊導入IE瀏覽器

13 配置DNS解析

www.test.com 為192.168.29.100

或者 修改windows 下的C:WindowsSysteme32driversetchosts文件

192.168.29.100    www.test.com

14 打開IE瀏覽器測試

輸入https://www.test.com

好了 成功了 好用成就感呀?。?
