資料權限設定

SSL => chmod 755 

private => chmod 710 private

檔案:

The .crt file  (chown root:root and chmod 644)

private key location; (chown root:ssl-cert and chmod 640)

---------------------------------------------------------

Note:
chmod 710 supports ssl-cert group under Ubuntu. (See comments)
Setting permission to 700 on /etc/apache2/ssl/private will also work fine.

Place SSL files:

Put public www ssl certificate(s) along with intermediate certificate(s) in /etc/apache2/ssl
Put private ssl key(s) in /etc/apache2/ssl/private

Set owner:

sudo chown -R root:root /etc/apache2/ssl/
sudo chown -R root:ssl-cert /etc/apache2/ssl/private/

Note:
If you do not have ssl-cert group, just use 'root:root' on line above or skip 2nd line.

Set permissions:

Public Certificate(s)

sudo chmod 644 /etc/apache2/ssl/*.crt

Private Key(s)

sudo chmod 640 /etc/apache2/ssl/private/*.key

Note:
The group permission is set to READ (640) due to Ubuntu ssl-cert group. '600' is fine as well.

Enable the Apache SSL module

sudo a2enmod ssl

Edit any Apache site files and enable

(see last paragraph) *

sudo nano /etc/apache/sites-available/mysiteexample-ssl.conf
sudo a2ensite mysiteexample-ssl
#             ^^^^^^^^^^^^^^^^^ <-Substitute your ".conf" filename(s)

Restart Apache2 service

sudo service apache2 restart

or

sudo systemctl restart apache2.service
