自建Apache的CA证书
（环境：Centos7）
PS：建议实验前把防火墙和SELinux都关掉。
- 安装apache环境依赖
[root@qmfz ~]# yum -y install mod_ssl openssl httpd

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.
