20.Generate the SSL private keys required for each of your hostnames:
mkdir -p /root/certificates/2023
cd /root/certificates/2023
openssl genrsa -out elentra.med.university.edu.key 2048
openssl genrsa -out staging.med.university.edu.key 2048
21.Generate the SSL certificate signing requests (CSRs) for your certificate authority for each of your hostnames.
openssl req -new -key elentra.med.university.edu.key -out elentra.med.university.edu.csr
openssl req -new -key staging.med.university.edu.key -out staging.med.university.edu.csr
You will be asked a number of questions, answer accordingly, but do not answer enter anything for "Email Address", "A challenge password", or "An optional company name:
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) [XX]:CA
State or Province Name (full name) []:Ontario
Locality Name (eg, city) [Default City]:Kingston
Organization Name (eg, company) [Default Company Ltd]:Queen's University
Organizational Unit Name (eg, section) []:Health Sciences Education Technology Unit
Common Name (eg, your name or your server's hostname) []:elentra.med.university.edu
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
22.If you have a valid Certificate Authority certificate, you should create a .crt file foreach hostname and paste in the certificate text:
vim /root/certificates/2023/elentra.med.university.edu.crt
vim /root/certificates/2023/staging.med.university.edu.crt
You will also likely have a certificate authority root chain certificate. Also paste this into a file called ca-certificate.crt
23.If you are only creating self-signed certificates, you should do this for each hostname:
openssl x509 -req -days 365 -in elentra.med.university.edu.csr -signkey elentra.med.university.edu.key -out elentra.med.university.edu.crt
openssl x509 -req -days 365 -in staging.med.university.edu.csr -signkey staging.med.university.edu.key -out staging.med.university.edu.crt
24.Install the certificates in the Apache virtual host directory:
mkdir /var/www/vhosts/elentra.med.university.edu/cert/
cp /root/certificates/2023/elentra.med.university.edu.crt /var/www/vhosts/elentra.med.university.edu/cert/
cp /root/certificates/2023/elentra.med.university.edu.key /var/www/vhosts/elentra.med.university.edu/cert/
mkdir /var/www/vhosts/staging.med.university.edu/cert/
cp /root/certificates/2023/staging.med.university.edu.crt /var/www/vhosts/staging.med.university.edu/cert/
cp /root/certificates/2023/staging.med.university.edu.key /var/www/vhosts/staging.med.university.edu/cert/
25.Create the Apache VirtualHosts by creating a file named 000-elentra.conf and placing it /etc/httpd/conf.d/.
For configurations where the web server is directly accessible from the internet, the file should contain the following:
# This will limit what information Apache reveals about itself.
ServerTokens Prod
ServerSignature Off
TraceEnable Off
​

20.Generate the SSL private keys required for each of your hostnames:
mkdir -p /root/certificates/2023
cd /root/certificates/2023
openssl genrsa -out elentra.med.university.edu.key 2048
openssl genrsa -out staging.med.university.edu.key 2048
21.Generate the SSL certificate signing requests (CSRs) for your certificate authority for each of your hostnames:
openssl req -new -key elentra.med.university.edu.key -out elentra.med.university.edu.csr
openssl req -new -key staging.med.university.edu.key -out staging.med.university.edu.csr
You will be asked a number of questions, answer accordingly, but do not answer enter anything for "Email Address", "A challenge password", or "An optional company name":
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) [XX]:CA
State or Province Name (full name) []:Ontario
Locality Name (eg, city) [Default City]:Kingston
Organization Name (eg, company) [Default Company Ltd]:Queen's University
Organizational Unit Name (eg, section) []:Health Sciences Education Technology Unit
Common Name (eg, your name or your server's hostname) []:elentra.med.university.edu
Email Address []:
Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
22.If you have a valid Certificate Authority certificate, you should create a .crt file foreach hostname and paste in the certificate text:
vim /root/certificates/2023/elentra.med.university.edu.crt
vim /root/certificates/2023/staging.med.university.edu.crt
You will also likely have a certificate authority root chain certificate. Also paste this into a file called ca-certificate.crt.\
23.If you are only creating self-signed certificates, you should do this for each hostname:
openssl x509 -req -days 365 -in elentra.med.university.edu.csr -signkey elentra.med.university.edu.key -out elentra.med.university.edu.crt
openssl x509 -req -days 365 -in staging.med.university.edu.csr -signkey staging.med.university.edu.key -out staging.med.university.edu.crt
24.Install the certificates in the Apache virtual host directory:
mkdir /var/www/vhosts/elentra.med.university.edu/cert/
cp /root/certificates/2023/elentra.med.university.edu.crt /var/www/vhosts/elentra.med.university.edu/cert/
cp /root/certificates/2023/elentra.med.university.edu.key /var/www/vhosts/elentra.med.university.edu/cert/
mkdir /var/www/vhosts/staging.med.university.edu/cert/
cp /root/certificates/2023/staging.med.university.edu.crt /var/www/vhosts/staging.med.university.edu/cert/
cp /root/certificates/2023/staging.med.university.edu.key /var/www/vhosts/staging.med.university.edu/cert/
25.Create the Apache VirtualHosts by creating a file named 000-elentra.conf and placing it /etc/httpd/conf.d/.

This file should contain the following:
# This will limit what information Apache reveals about itself.
ServerTokens Prod
ServerSignature Off

22.If you have a valid Certificate Authority certificate, you should create a .crt file foreach hostname and paste in the certificate text:
vim /root/certificates/2023/elentra.med.university.edu.crt
vim /root/certificates/2023/staging.med.university.edu.crt
You will also likely have a certificate authority root chain certificate. Also paste this into a file called ca-certificate.crt.\
23.If you are only creating self-signed certificates, you should do this for each hostname:
openssl x509 -req -days 365 -in elentra.med.university.edu.csr -signkey elentra.med.university.edu.key -out elentra.med.university.edu.crt
openssl x509 -req -days 365 -in staging.med.university.edu.csr -signkey staging.med.university.edu.key -out staging.med.university.edu.crt
24.Install the certificates in the Apache virtual host directory:
mkdir /var/www/vhosts/elentra.med.university.edu/cert/
cp /root/certificates/2023/elentra.med.university.edu.crt /var/www/vhosts/elentra.med.university.edu/cert/
cp /root/certificates/2023/elentra.med.university.edu.key /var/www/vhosts/elentra.med.university.edu/cert/
mkdir /var/www/vhosts/staging.med.university.edu/cert/
cp /root/certificates/2023/staging.med.university.edu.crt /var/www/vhosts/staging.med.university.edu/cert/
cp /root/certificates/2023/staging.med.university.edu.key /var/www/vhosts/staging.med.university.edu/cert/
25.Create the Apache VirtualHosts by creating a file named 000-elentra.conf and placing it /etc/apache2/sites-available/.

This file should contain the following:
# This will limit what information Apache reveals about itself.
ServerTokens Prod
ServerSignature Off
TraceEnable Off
​
SSLStaplingCache "shmcb:logs/stapling-cache(150000)"
​
