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.

#生成证书请求，注意我们要签发的是www.mei.com这个域名的证书
[root@foundation CA]# openssl req -new -key /etc/pki/tls/private/server.key -days 365 -out /etc/pki/tls/server.csr

9.2 搭建HTTPS网站

这是使用8008端口作为网站端口，然后做网站重定向到https。

如果要做把PHP作为https发布，可以直接在打完LAMP环境后将PHP相关网页直接拷贝到https所在的站目录下，然后做重定向即可。

9.2.1 安装软件包和配置防火墙

1 [root@foundation CA]# yum install mod_ssl
2 
3 [root@foundation CA]# firewall-cmd --permanent --add-service=https && firewall-cmd --reload   
4  
5 [root@foundation html]# firewall-cmd --permanent --add-port=8008/tcp --add-port=8008/udp
6 success
7 [root@foundation html]# firewall-cmd --reload

9.2.2 创建网站目录和生成相应的网页内容

创建网站目录

至于网站目录SELinux相关的问题由于前面配置时讲过，这里就不赘述了。

下面的index.html中的内容为字串：test

所有有关PHP的文件都是我从以前配置LAMP时的测试文件。如果仅仅是自己搭建一个PHP网站，可以自己写PHP测试文件的内容。

9.2.3 创建虚拟主机并做好配置

[root@foundation /]# cat /etc/httpd/conf.d/httpswww.conf 
<VirtualHost *:443>
    DocumentRoot "/web/www/httpswww/html"
    ServerName www.mei.com
    SSLEngine on
    SSLProtocol all -SSLv2
    SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5
    SSLCertificateFile /etc/pki/tls/certs/server.crt
    SSLCertificateKeyFile /etc/pki/tls/private/server.key
    <Directory /web/www>
        AllowOverride None
        Require all granted
    </Directory>
    <Directory /web/www/httpswww/html>
        AllowOverride None
        Require all granted
    </Directory>
    ErrorLog "logs/httpswww_error.log"
    CustomLog "logs/httpswww_access.log" combined
</VirtualHost>
<VirtualHost *:8008>
    ServerName www.mei.com
    RewriteEngine  On #开启重写引擎
    #RewriteRule ^(/.*)$ https://%{HTTP_POST}$1 [redirect=301]
    RewriteCond %{SERVER_PORT} !^443$  #重写
    RewriteRule ^(.*)?$ https://%{SERVER_NAME}$1 [R=301,L]  #重写的策略
</VirtualHost>

.3 测试

拷贝foundation中的CA证书到rhel7主机，可以把证书放到网站上自由下载，这里就不做了，直接使用scp拷贝。

[root@foundation CA]# scp /etc/pki/CA/cacert.pem foundation@rhel7.mei.com:/home/foundation/

打开Firefox添加证书

选择import后找到刚才拷过来的证书文件双击，来到下面的界面，勾选一下选项。

输入http地址访问

看到下面的效果，并显示是https且证书安全，说明成功！

再测试一下我们的PHP内容：

能够跳到https，并且证书安全。

点击select能够正确查询到数据库中的内容，并显示证书是安全的，同时还是https

最后希望大家提意见、转发、评论和交流！！！
