https://www.cnblogs.com/ance/p/10265962.html#i4 自制u盘镜像并安装
证书签名过程：1、网页服务器生成证书请求文件；2、认证中心确认申请者的身份真实性；3、认证中心使用根证书的私钥加密证书请求文件，生成证书；4、把证书传给申请者。
一、实验环境
node1 192.168.40.132 CA认证中心（也要给自己颁发根证书）
node2 192.168.40.211 网页服务器
由于没有真实域名，所以自己搭建一个CA认证中心，实际只要去申请一个就好了。

二.Apache实现https
备一个httpd，需要包含ssl模块
[[email protected] ~]# yum -y install httpd mod_ssl
[[email protected] ~]# vim /etc/httpd/conf/httpd.conf
ServerName 192.168.5.102:80 //第95行
[[email protected] ~]# systemctl start httpd.service
[[email protected] ~]firewall-cmd --permanent --zone=public --add-port=80/tcp
[[email protected] ~]firewall-cmd --reload
生成证书请求文件，并发给CA认证中心node1
