Step 1: Make sure ownCloud server 5 is installed correctly, you can see guide how to install ownCloud 5 here, Login to ubuntu server via ssh then switch to root mode.
sudo -i
Step 2: Editing file /etc/apache2/sites-enabled/000-default, change “AllowOverride None” to “AllowOverride All”
nano /etc/apache2/sites-enabled/000-default
Step 3. you need to enable apache module mod_rewrite, mod_headers and mod_ssl, to enable both module use following command:
a2enmod rewrite && a2enmod headers && a2enmod ssl
Restart apache2 daemon:
service apache2 restart
Step 4. On this step you need to editing file configuration /etc/ssl/openssl.cnf,
nano /etc/ssl/openssl.cnf
Find and change the following line:
dir = /root/SSLCertAuth default_days = 3650 # 10 years default_bits = 2048 # recommended by NSA until 2030 countryName_default = US 0.organizationName_default = Ubuntu Contrib
Step 5. Create Directory for save all file SSL Certificate Authority, on this case I will make directory name “SSLCertAuth”
mkdir /root/SSLCertAuth
chmod 700 /root/SSLCertAuth
cd /root/SSLCertAuth
mkdir certs private newcerts
echo 1000 > serial
touch index.txt
Step 6. Run the following command to generating Certificate Authority (CA)
openssl req -new -x509 -days 3650 -extensions v3_ca \ -keyout private/cakey.pem -out cacert.pem \ -config /etc/ssl/openssl.cnf
Output:
If you want to keep the default value, Hit [enter]
Step 7. Creating Certificate Signing Request
openssl req -new -nodes \ -out apache-req.pem \ -keyout private/apache-key.pem \ -config /etc/ssl/openssl.cnf
Output:
Step 8. Generate the certificate then copy the files to directory /etc/ssl :
openssl ca \ -config /etc/ssl/openssl.cnf \ -out apache-cert.pem \ -infiles apache-req.pem
output:
mkdir /etc/ssl/crt mkdir /etc/ssl/key cp /root/SSLCertAuth/apache-cert.pem /etc/ssl/crt cp /root/SSLCertAuth/private/apache-key.pem /etc/ssl/key
Step 9. This final step W’ll to Configure HTTPS apache2 web server, create directory SSL log and create new file /etc/apache2/conf.d/owncloud5-ssl.conf to add the SSL virtualhost.
mkdir/var/www/logs
nano /etc/apache2/conf.d/owncloud5-ssl.conf
copy and paste this configuration:
<VirtualHost *:443> ServerName 192.168.1.5 SSLEngine on SSLCertificateFile /etc/ssl/crt/apache-cert.pem SSLCertificateKeyFile /etc/ssl/key/apache-key.pem DocumentRoot /var/www/owncloud CustomLog /var/www/logs/ssl-access_log combined ErrorLog /var/www/logs/ssl-error_log </VirtualHost>
Note: on this case my IP server 192.168.1.5, you can replace IP with your server hostname or domain
service apache2 restart
you now have secured, access owncloud using your favorite browser by typing on addressbar https://192.168.1.5 , it will appear like following screenshot
