Install SSL Certificate on zPanel

The following is an simplified how to install SSL Certificate on zPanel. You can use a self-signed SSL Certificate or buy.

First create ssl directory to easy maintain:
$ mkdir /var/zpanel/hostdata/zadmin/ssl

Then go to ssl directory:
$ cd /var/zpanel/hostdata/zadmin/ssl

Generate private key. If you use a self signed SSL Certificate, you can use 1024 RSA key, but if you buy a certificate like InstantSSL, most of them need at least 2048 bit RSA key.
$ openssl genrsa -des3 -out server.key 2048

Generate CSR (Certificate Signing Request):
$ openssl req -new -key server.key -out server.csr

Remove Passphrase from Key
$ cp server.key
$ openssl rsa -in -out server.key

If you want to use a self signed, generate a self signed certificate:
$ openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

Or if you want to buy a certificate, please submit server.key to a SSL Provider, then you’ll get .crt and .ca-bundle files.

Install the Private Key and Certificate.
Please make sure mod_ssl was installed on your server. If didn’t installed yet, you can install it.
For CentOS:
# yum install mod_ssl
For Ubuntu:
# apt-get install mod_ssl

Go Server Admin – Module Admin – Override a Virtual Host Setting – Select a domain and click Select Vhost:
On port override field, fill: 443
Check ‘Forward Port 80 to Overriden Port’ if you want to always use HTTPS
Fill IP Override with your Server IP Address.
If you use a self-signed certificate, fill custom entry with:
SSLEngine On
SSLCertificateFile /var/zpanel/hostdata/zadmin/ssl/server.crt
SSLCertificateKeyFile /var/zpanel/hostdata/zadmin/ssl/server.key
DocumentRoot "/var/zpanel/hostdata/zadmin/public_html/yourdirectory"

If you use trusted SSL Certificate, fill custom entry with:
SSLEngine On
SSLCertificateFile /var/zpanel/hostdata/zadmin/ssl/server.crt
SSLCertificateKeyFile /var/zpanel/hostdata/zadmin/ssl/server.key
SSLCertificateChainFile /var/zpanel/hostdata/zadmin/ssl/
DocumentRoot "/var/zpanel/hostdata/zadmin/public_html/yourdirectory"

Click Save VHost

Then final step restart apache:
#/etc/init.d/httpd stop
#/etc/init.d/httpd start

    can i use this tutorial for ubuntu 12.04

    • Arnas Risqianto says:

      yes, it should work for ubuntu

      • Chomps says:

        It will work up as far as “apt-get install mod_ssl”

        Run the command dpkg -S Chances are that it will display something like:

        apache2.2-common: /usr/lib/apache2/modules/
        It means that mod_ssl is already installed on your system, as it does not come in a separate package, but it is bundled in apache2.2-common. Run

        a2enmod ssl
        to enable it, if it is not already enabled.

    Nice to hear that, I would also make a backup of your vhosts file because when you do add a new domain from zpanel in future it seems to overwrite the ssl settings. So if you do have it backed up, you can easily add it again.

    • Arnas Risqianto says:

      Yes right since zpanel read from database then write into config file so when you change directly the config file, it’ll overwrite the config file when you add new domain.
