How to enable SSL on Apache Fedora 26

Fedora Tutorial – Hello Linux users, today we will learn how to secure our web server by enable SSL on Apache Fedora 26. On my previous tutorial, we have learned how to install and configure LAMP Server on Fedora 26. If you follow that guide, it would be easier for you to continue to secure your web server with this tutorial. There are several steps to enable SSL on web server Fedora 26.

Steps to enable SSL on Apache Fedora 26

Step 1. Create Certificate

First, we need to create a new SSL certificate. Log in to the server and execute these commands below.

cd /etc/pki/tls/certs
make server.key

Output example

[root@fedora certs]# make server.key
umask 77 ; \
/usr/bin/openssl genrsa -aes128 2048 > server.key
Generating RSA private key, 2048 bit long modulus
.....................................+++
...+++
e is 65537 (0x010001)
Enter pass phrase:
Verifying - Enter pass phrase:

Now we need to remove pass phrase from the private key

[root@fedora certs]# openssl rsa -in server.key -out server.key
Enter pass phrase for server.key:
writing RSA key

Create server.csr

make server.csr

Output Example

[root@fedora certs]# make server.csr
umask 77 ; \
/usr/bin/openssl req -utf8 -new -key server.key -out server.csr
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]:ID
State or Province Name (full name) []:Solo
Locality Name (eg, city) [Default City]:Solo
Organization Name (eg, company) [Default Company Ltd]:manjaro.site
Organizational Unit Name (eg, section) []:IT
Common Name (eg, your name or your server's hostname) []:manjaro.site
Email Address []:admin@manjaro.site

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:  #Press Enter
An optional company name []:   #Press Enter

Followed by the last command

openssl x509 -in server.csr -out server.crt -req -signkey server.key -days 3650

Output

[root@fedora certs]# openssl x509 -in server.csr -out server.crt -req -signkey server.key -days 3650
Signature ok
subject=C = ID, ST = Solo, L = Solo, O = manjaro.site, OU = IT, CN = manjaro.site, emailAddress = admin@manjaro.site
Getting Private key

Now we have completed to create SSL certificate.

Step 2. Configure HTTPD for SSL

Install mod_ssl

dnf install mod_ssl

Output

[root@fedora certs]# dnf install mod_ssl

Is this ok [y/N]:

Edit /etc/httpd/conf.d/ssl.conf

nano /etc/httpd/conf.d/ssl.conf

Now find and uncomment line 59 and 60 and change them to the following. Off course you need to modify the server name with your own.

DocumentRoot "/var/www/html"
ServerName www.manjaro.site:443

On Line 76 and 77, change them to:

SSLProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2
SSLProxyProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2

On line 98 change to the following

SSLCertificateFile /etc/pki/tls/certs/server.crt

Also on line 105 change it to the following

SSLCertificateKeyFile /etc/pki/tls/certs/server.key

Close and save the file. Finally restart httpd

systemctl restart httpd

Now try accessing the web server using https

https://ip-server

You will see such error above. It is normal since we use self signed certificate on the system. Thank you for reading this post on How to enable SSL on Apache Fedora 26. See you on the next tutorial.
