\"SSL<\/p>\n\n\n\n

I’m no webmaster. Any knowledge I have in web hosting, servers, or coding is from self-teaching and alot of trial and error. Along the way, I’ve learned a secure site is important to prevent hacking, database injections, and to increase the site’s presence on the internet (basically its Google ranking). So it’s important to have a SSL\/TLS certifcate installed on your site. Let’s Encrypt offers SSL\/TLS cerficates for free! However, you can support the organization through donations. Here’s how to install a Let’s Encyrpt Certificate in a Sentora \/CentOS environment.<\/p>\n\n\n\n

\n

CAUTION<\/strong> #1<\/strong>: Do NOT <\/strong>use the Let’s Encrypt: Sentora Domains<\/a> instructions found in Sentora’s documentation<\/a>. It’s outdated and doesn’t work.<\/p>\n\n\n\n

How do I know? <\/strong><\/p>\n\n\n\n

One, the link for the github repository for Let’sEncrypt is incorrect. It’s no longer under Let’s Encrypt. It’s under Certbot. <\/p>\n\n\n\n

Two, the code from Sentora’s doesn’t work. I updated the repository link to no avail. <\/p>\n\n\n\n

CAUTION #2: <\/strong>You will get errors when you follow this tutorial after<\/span> following Sentora’s instructions. The two methods do not play together nicely. Trust me! I had to send a SOS to my hosting provider when Sentora locked me out.<\/p>\n<\/div><\/div>\n\n\n\n

SSH into your server<\/h4>\n\n\n\n

I use putty.<\/p>\n\n\n\n

Install Certbot<\/h4>\n\n\n\n
wget https:\/\/dl.eff.org\/certbot-auto\nsudo mv certbot-auto \/usr\/local\/bin\/certbot-auto\nsudo chown root \/usr\/local\/bin\/certbot-auto\nsudo chmod 0755 \/usr\/local\/bin\/certbot-auto<\/code><\/pre>\n\n\n\n
Get a Certificate from Let’s Encrypt and have Certbot automatically edit the Apache configuration for you.<\/h4>\n\n\n\n
sudo \/usr\/local\/bin\/certbot-auto --apache<\/code><\/pre>\n\n\n\n
Setup Automatic Renewal<\/h4>\n\n\n\n
echo \"0 0,12 * * * root python -c 'import random; import time; time.sleep(random.random() * 3600)' && \/usr\/local\/bin\/certbot-auto renew -q\" | sudo tee -a \/etc\/crontab > \/dev\/null<\/code><\/pre>\n\n\n\n
Use SSL Labs<\/a> (recommended by Certbot) to confirm your site’s security and https:\/\/ installation <\/h4>\n\n\n\n
\n\n\n\n
Is SSL3 causing vulnerability on your site?  <\/strong><\/h3>\n\n\n\n
I was disappointed to discover SSL Labs rated my site with a B<\/strong> after all that work!  No worries.  To boost your SSL Labs rating to an A<\/strong>, follow my tutorial How to Disable SSL2 and SSL3 Protocols in a Sentora \/ CentOS \/ Apache Environment<\/a> tutorial.<\/p>\n","protected":false},"excerpt":{"rendered":"
