How to Install SSL Certificate on NGINX
1. Generate file .key and .csr
Don’t miss to set
Common Nameas*.mydomain.combecause we use GlobalSign Wildcard AlphaSSL.
$ openssl req -new -newkey rsa:2048 -nodes -keyout mydomain.com.key -out mydomain.com.csr
Generating a 2048 bit RSA private key
...............................................................+++
.....................+++
writing new private key to 'mydomain.com.key'
-----
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:ID
State or Province Name (full name) [Some-State]:Jakarta
Locality Name (eg, city) []:North Jakarta
Organization Name (eg, company) [Internet Widgits Pty Ltd]:PT. Wong Fang Chai
Organizational Unit Name (eg, section) []:Logistic
Common Name (e.g. server FQDN or YOUR name) []:*.mydomain.com
Email Address []:[email protected]
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:MyPassword123
An optional company name []:My Company Name
And the result of it, is look like this:
$ cat mydomain.com.csr

2. Put that BEGIN CERTIFICATE REQUEST into your SSL Provider
- For example, I using rumahweb provider.
- Choose domain validation (in this method, you can using email, domain, dns, or etc).
3. Configure domain validation in your vps server.
Put this meta tag below into your
/.well-known/pki-validation/gsdv.txtYou can usingsshto login into your server, makesure the port 22 (for ssh) is opened.
<meta name="_globalsign-domain-verification" content="xxxxxxx-xxx-xxxx" />
ubuntu@ip-xxx-xx-x-xxx:~$ cd /var/www/html/
ubuntu@ip-xxx-xx-x-xxx:/var/www/html$ ls
index.nginx-debian.html
ubuntu@ip-xxx-xx-x-xxx:/var/www/html$ sudo mkdir -p .well-known/pki-validation
ubuntu@ip-xxx-xx-x-xxx:/var/www/html$
ubuntu@ip-xxx-xx-x-xxx:/var/www/html$ sudo nano .well-known/pki-validation/gsdv.txt
ubuntu@ip-xxx-xx-x-xxx:/var/www/html$
4. Setup the .crt and .key in the server.
Finally, after domain validation was configured after waiting a configuration,
the SSL Provider will provide you the some keys, eg: rootCert, interCert, X509Cert and etc.
Combine that X509Cert and interCert as mydomain.com.crt file.
NOTE: Please put it in order (1:X509Cert, 2:interCert)
ubuntu@ip-xxx-xx-x-xxx:/etc/ssl$ cat mydomain.com.crt

5. Setup Nginx
$ sudo nano /etc/nginx/sites-available/mydomain.com
Inside file of mydomain.com, add your /etc/ssl/mydomain.com.crt
and /etc/ssl/mydomain.com.key into this file.
server {
listen 80;
server_name mydomain.com www.mydomain.com;
return 301 https://$server_name$request_uri;
}
server {
# Install SSL
listen 443 ssl;
ssl_certificate /etc/ssl/mydomain.com.crt;
ssl_certificate_key /etc/ssl/mydomain.com.key;
root /var/www/html;
# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;
server_name mydomain.com www.mydomain.com;
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
}
# add Strict-Transport-Security to prevent man in the middle attacks
add_header Strict-Transport-Security "max-age=31536000" always;
}
Don’t miss to create a symlink file.
$ sudo ln -s /etc/nginx/sites-available/mydomain.com /etc/nginx/sites-enabled/
And then you can test it using sudo service nginx -t, if it passed you can restart the nginx server.
ubuntu@ip-xxx-xx-x-xxx:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
ubuntu@ip-xxx-xx-x-xxx:~$ sudo systemctl restart nginx
ubuntu@ip-xxx-xx-x-xxx:~$ sudo systemctl restart gunicorn # if you have gunicorn
6. Finally
Finally, you can checkout your domain mydomain.com, it will automaticly redirect as https mode.
To check your keys chain is correct or not, you can checkout at https://whatsmychaincert.com/?mydomain.com
