By now you probably know how important running your websites or blogs over HTTPS is… Google and other search engine providers are ranking sites using SSL/TLS or HTTPS better than those that are not.
Even today, most website providers are making all their customers’ websites HTTPS compliant by default… So if you’re still running your WordPress websites or blogs not using HTTPS, then you’re probably doing it wrong.
This brief tutorial is going to show students and new users how to convert existing WordPress websites from HTTP to HTTPS easily without losing your audience.
When you’re done, all traffic to your sites will be redirected to the HTTPS version of your content.
To get started with migrating your WordPress sites to HTTPS, continue with the steps below:
Step 1: Setup Let’s Encrypt Free SSL / TLS
The first step going all HTTPS is obtaining SSL/TLS certificates for your domain or site. Since Let’s Encrypt is free, continue below to obtain your free certificates to use.
Before obtaining Let’s Encrypt certificates, make sure your Apache2 configuration is setup correctly… for your site config file, make sure the ServerName and ServerAlias are defined.
<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/wordpress/
ServerName example.com
ServerAlias www.example.com
.............
.............
When those settings are confirmed, continue below to get the certificate for your domain name.
To get the Let’s Encrypt SSL/TLS client installed on Ubuntu, run the commands below
sudo apt-get install python-certbot-apache
After that run the commands below to obtain your free Let’s Encrypt SSL/TLS certificate for your site.
sudo certbot --apache -m admin@example.com -d example.com -d www.example.com
After running the above commands, you should get prompted to accept the licensing terms. If everything is checked, the client should automatically install the free SSL/TLS certificate and configure the Nginx site to use the certs.
Please read the Terms of Service at

agree in order to register with the ACME server at

This is how easy is it to obtain your free SSL/TLS certificate for your Nginx powered website.
Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access. ------------------------------------------------------------------------------- 1: No redirect - Make no further changes to the webserver configuration. 2: Redirect - Make all requests redirect to secure HTTPS access. Choose this for new sites, or if you're confident your site works on HTTPS. You can undo this change by editing your web server's configuration. ------------------------------------------------------------------------------- Select the appropriate number [1-2] then [enter] (press 'c' to cancel): 2
Pick option 2 to redirect all traffic over HTTPS. This is important!
After that, the SSL client should install the cert and configure your website to redirect all traffic over HTTPS.
Congratulations! You have successfully enabled https://example.com and https://www.example.com You should test your configuration at: https://www.ssllabs.com/ssltest/analyze.html?d=example.com https://www.ssllabs.com/ssltest/analyze.html?d=www.example.com ------------------------------------------------------------------------------- IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at: /etc/letsencrypt/live/example.com/fullchain.pem Your key file has been saved at: /etc/letsencrypt/live/example.com/privkey.pem Your cert will expire on 2018-02-24. To obtain a new or tweaked version of this certificate in the future, simply run certbot again with the "certonly" option. To non-interactively renew *all* of your certificates, run "certbot renew" - If you like Certbot, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le
The highlighted code block should be added to your Apache2 WordPress configuration file automatically by Let’s Encrypt certbot. Your WordPress site is ready to be used over HTTPS.
<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/wordpress/
ServerName example.com
ServerAlias www.example.com
<Directory /var/www/html/wordpress/>
Options +FollowSymlinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =example.com [OR]
RewriteCond %{SERVER_NAME} =www.example.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>
A new configuration file for the domain should also be created named /etc/apache2/sites-available/example-le-ssl.conf. This is Apache2 SSL module configuration file and should contain the certificate definitions defined in it.
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/wordpress/
ServerName example.com
ServerAlias www.example.com
<Directory /var/www/html/wordpress/>
Options +FollowSymlinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLCertificateFile /etc/letsencrypt/live/example.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/example.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>
Step 2: Change WordPress Site URL
After configuring Apache2 to use HTTPS above, change WordPress site URL to use HTTPS… this can be done by editing wp-config.php file in your WordPress root directory.
sudo nano /var/www/html/example.com/wp-config.php
Open WordPress wp-config.php file in your WordPress root directory and add the lines below:
?php
//Use HTTPS for WordPress
define('WP_HOME','https://example.com');
define('WP_SITEURL','https://example.com');
define('FORCE_SSL_ADMIN', true);
Save the file
Now you should be able to logon to WordPress admin dashboard via HTTPS…
Step 3: Install Search & Replace Plugin
Finally, logon to WordPress dashboard and install Search & Replace plugin to switch all HTTP references in the database to HTTPS
After installing and activating the plugin, go to Tools –> Search & Replace… then as shown in the image below, search and replace the non http URL with the https version for all tables.
This should do it.
After that, your site should be HTTPS compliant.
Congratulations! You’ve successfully converted from HTTP to HTTPS
To setup a process to automatically renew the certificates, add a cron job to execute the renewal process.
sudo crontab -e
Then add the line below and save.
0 1 * * * /usr/bin/certbot renew & > /dev/null
The cron job will attempt to renew 30 days before expiring
