Pengantar

TLS, atau transport layer security, dan pendahulunya SSL, secure socket layer, adalah protokol keamanan yang dibuat untuk menempatkan lalu lintas normal dalam bungkus terenkripsi yang dilindungi.

Protokol ini memungkinkan lalu lintas dikirim dengan aman di antara pihak-pihak yang berjauhan tanpa kemungkinan lalu lintas dicegat dan dibaca oleh seseorang di tengahnya. Mereka juga berperan dalam memvalidasi identitas domain dan server di seluruh internet dengan membuat server sebagai terpercaya dan asli oleh otoritas sertifikat.

Dalam panduan ini, kami akan membahas cara membuat sertifikat SSL yang ditandatangani sendiri untuk Apache di server Ubuntu terbaru, yang memungkinkan Anda mengenkripsi lalu lintas ke server Anda. Meskipun ini tidak memberikan manfaat validasi pihak ketiga terhadap identitas server Anda, namun ini memenuhi persyaratan orang-orang yang hanya ingin mentransfer informasi dengan aman.

Catatan: Anda mungkin ingin mempertimbangkan untuk menggunakan Let's Encrypt daripada self-signed certificatei. Let's Encrypt adalah otoritas sertifikat baru yang mengeluarkan sertifikat SSL / TLS gratis yang dipercaya di kebanyakan browser web.

Kebutuhan

Install apache

sudo apt-get update
sudo apt-get install apache2

Step 1 - Aktifkan SSL Module

Aktifkan SSL & restart apache

sudo a2enmod ssl
sudo service apache2 restart

Step 2 - buat self-sign SSL certificate

Buat folder SSL & buat self-signed certificate

sudo mkdir /etc/apache2/ssl
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt

Artinya

openssl - perintah untuk operasi SSL
req - X.509 certificate signing request (CSR)
X.509 - self-signed
nodes - key file tidak perlu di amankan dengan passphrase
days 365 - valid untuk 1 tahun
newkey rsa:2048: buat CSR dan private key bersamaan. RSA key panjangnya 2048 bit.
keyout: nama outfile dari private key yang dibuat.
out: nama certificate file yang dibuat.

Setelah tekan "ENTER", ada beberapa pertanyaan / jawaban yang perlu dilakukan dalam proses adalah,

Country Name (2 letter code) [AU]:US
State or Province Name (full name) [Some-State]:New York
Locality Name (eg, city) []:New York City
Organization Name (eg, company) [Internet Widgits Pty Ltd]:Your Company
Organizational Unit Name (eg, section) []:Department of Kittens
Common Name (e.g. server FQDN or YOUR name) []:your_domain.com
Email Address []:your_email@domain.com

Sertificate & key akan di letakan di directory /etc/apache2/ssl

Step Three — Configure Apache to Use SSL

Now that we have our certificate and key available, we can configure Apache to use these files in a virtual host file. You can learn more about how to set up Apache virtual hosts here.

Instead of basing our configuration file off of the 000-default.conf file in the sites-available subdirectory, we're going to base this configuration on the default-ssl.conf file that contains some default SSL configuration.

Open the file with root privileges now:

sudo nano /etc/apache2/sites-available/default-ssl.conf

With the comments removed, the file looks something like this:

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        SSLEngine on
        SSLCertificateFile /etc/ssl/certs/ssl-cert-snakeoil.pem
        SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
        <FilesMatch "\.(cgi|shtml|phtml|php)$">
                        SSLOptions +StdEnvVars
        </FilesMatch>
        <Directory /usr/lib/cgi-bin>
                        SSLOptions +StdEnvVars
        </Directory>
        BrowserMatch "MSIE [2-6]" \
                        nokeepalive ssl-unclean-shutdown \
                        downgrade-1.0 force-response-1.0
        BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
    </VirtualHost>
</IfModule>

This may look a bit complicated, but luckily, we don't need to worry about most of the options here.

We want to set the normal things we'd configure for a virtual host (ServerAdmin, ServerName, ServerAlias, DocumentRoot, etc.) as well as change the location where Apache looks for the SSL certificate and key.

In the end, it will look something like this. The entries in red were modified from the original file:

<IfModule mod_ssl.c>
    <VirtualHost _default_:443>
        ServerAdmin admin@example.com
        ServerName your_domain.com
        ServerAlias www.your_domain.com
        DocumentRoot /var/www/html
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined
        SSLEngine on
        SSLCertificateFile /etc/apache2/ssl/apache.crt
        SSLCertificateKeyFile /etc/apache2/ssl/apache.key
        <FilesMatch "\.(cgi|shtml|phtml|php)$">
                        SSLOptions +StdEnvVars
        </FilesMatch>
        <Directory /usr/lib/cgi-bin>
                        SSLOptions +StdEnvVars
        </Directory>
        BrowserMatch "MSIE [2-6]" \
                        nokeepalive ssl-unclean-shutdown \
                        downgrade-1.0 force-response-1.0
        BrowserMatch "MSIE [17-9]" ssl-unclean-shutdown
    </VirtualHost>
</IfModule>

Save and exit the file when you are finished.

Step Four — Activate the SSL Virtual Host

Now that we have configured our SSL-enabled virtual host, we need to enable it.

We can do this by typing:

sudo a2ensite default-ssl.conf

We then need to restart Apache to load our new virtual host file:

sudo service apache2 restart

This should enable your new virtual host, which will serve encrypted content using the SSL certificate you created.

Step Five — Test your Setup

Now that you have everything prepared, you can test your configuration by visiting your server's domain name or public IP address after specifying the https:// protocol, like this:

https://server_domain_name_or_IP

You will get a warning that your browser cannot verify the identity of your server because it has not been signed by one of the certificate authorities that it trusts.

apache ssl warning

This is expected since we have self-signed our certificate. While our certificate will not validate our server for our users because it has had no interaction with a trusted certificate authority, it will still be able to encrypt communication.

Since this is expected, you can hit the "Proceed anyway" button or whatever similar option you have in your browser.

You will now be taken to content in the DocumentRoot that you configured for your SSL virtual host. This time your traffic is encrypted. You can check this by clicking on the lock icon in the menu bar:

apache ssl encrypted

You can see in the middle green section that the connection is encrypted. Conclusion

You should now have SSL enabled on your website. This will help to secure communication between visitors and your site, but it will warn each user that the browser cannot verify the validity of the certificate.

If you are planning on launching a public site and need SSL, you will be better off purchasing an SSL certificate from a trusted certificate authority.

derek June 9, 2014 I have purchased SSL from GeoTrust. Now is there any tutorial to configure it? or what can I do to install it?

hnwebdesign5 June 10, 2014 This is a great tutorial, but could you do one on how to install a ssl certificate that was actually purchased? Please!

asb MOD June 10, 2014 @hnwebdesign5: It will be more or less the same using a cert that you purchased from a CA. The only difference is that you should replace:

SSLCertificateFile /etc/apache2/ssl/apache.crt
SSLCertificateKeyFile /etc/apache2/ssl/apache.key

with the cert provided by you CA:

SSLCertificateFile /path/to/your/ssl.crt                           
SSLCertificateKeyFile /path/to/your/private.key                        
SSLCertificateChainFile /path/to/your/bundle.pem

@derek: GeoTrust also has their own documentation:

-Prerequisites
-Before you begin, you should have some configuration already taken care of.
+==Kebutuhan==
-We will be operating as a non-root user with sudo privileges in this guide. You can set one up by following steps 1-4 in our Ubuntu 14.04 initial server setup guide.
+Install apache
-You are also going to need to have Apache installed. If you don't already have that up and running, you can quickly fix that by typing:
   sudo apt-get update
   sudo apt-get install apache2
-Step One — Activate the SSL Module
+==Step 1 - Aktifkan SSL Module==
-SSL support actually comes standard in the Ubuntu 14.04 Apache package. We simply need to enable it to take advantage of SSL on our system.
+Aktifkan SSL & restart apache
-Enable the module by typing:
   sudo a2enmod ssl
-After you have enabled SSL, you'll have to restart the web server for the change to be recognized:
   sudo service apache2 restart
-With that, our web server is now able to handle SSL if we configure it to do so.
+==Step 2 - buat self-sign SSL certificate==
-Step Two — Create a Self-Signed SSL Certificate
+Buat folder SSL & buat self-signed certificate
-Let's start off by creating a subdirectory within Apache's configuration hierarchy to place the certificate files that we will be making:
   sudo mkdir /etc/apache2/ssl
-Now that we have a location to place our key and certificate, we can create them both in one step by typing:
   sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt
-Let's go over exactly what this means.
+Artinya
-    openssl: This is the basic command line tool provided by OpenSSL to create and manage certificates, keys, signing requests, etc.
-    req: This specifies a subcommand for X.509 certificate signing request (CSR) management. X.509 is a public key infrastructure standard that SSL adheres to for its key and certificate managment. Since we are wanting to create a new X.509 certificate, this is what we want.
-    -x509: This option specifies that we want to make a self-signed certificate file instead of generating a certificate request.
-    -nodes: This option tells OpenSSL that we do not wish to secure our key file with a passphrase. Having a password protected key file would get in the way of Apache starting automatically as we would have to enter the password every time the service restarts.
-    -days 365: This specifies that the certificate we are creating will be valid for one year.
-    -newkey rsa:2048: This option will create the certificate request and a new private key at the same time. This is necessary since we didn't create a private key in advance. The rsa:2048 tells OpenSSL to generate an RSA key that is 2048 bits long.
-    -keyout: This parameter names the output file for the private key file that is being created.
-    -out: This option names the output file for the certificate that we are generating.
-When you hit "ENTER", you will be asked a number of questions.
-The most important item that is requested is the line that reads "Common Name (e.g. server FQDN or YOUR name)". You should enter the domain name you want to associate with the certificate, or the server's public IP address if you do not have a domain name.
