建立文件夹，存放sslkey

mkdir /etc/httpd/ssl/

建立凭证档

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/httpd/ssl/apache.key -out /etc/httpd/ssl/apache.crt

writing new private key to '/etc/httpd/ssl/apache.key'
-----
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]:CHN
string is too long, it needs to be less than  2 bytes long
Country Name (2 letter code) [XX]:CN

需要填写一些内容，我随便填的…

 

apache配置 
/etc/httpd/conf.d/ssl.conf 
我把这下面的内容复制到另外一个文件中配置的

<VirtualHost _default_:443>
*****
</VirtualHost>

需要修改的几项

DocumentRoot "/var/www/example.com/public_html"

ServerName www.example.com:443

SSLCertificateFile /etc/httpd/ssl/apache.crt
SSLCertificateKeyFile /etc/httpd/ssl/apache.key

重启apache

systemctl restart httpd.service

通过以上步骤就能打开网页的https链接了，但是此时的https浏览器会提示不安全的链接，那么就需要到阿里云去申请一个CA证书，目前有免费版的CA证书，下面的链接是我发在百度的申请证书的教程，大家可以参考一下

https变成绿色，说明证书生效！
