Obtain an SSL certificate(Let’s Encrypt)

Make sure you have the latest open ssl installed.

# dnf install openssl-devel

1. Install the certificate

# dnf -y install certbot
# certbot certonly –webroot -w /var/www/html/[Domain Name] -d [Domain Name]
# First time only, you need to register your email address and agree to the terms of use.
# Specify an email address that can be received.

Enter email address (used for urgent notices and lost key recovery)

<Administrator email address>

< OK > <Cancel>

# Agree to the terms of use
Please read the Terms of Service at
You must agree in order to register with the ACME server at

<Agree > <Cancel>

– Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/[Domain Name]/fullchain.pem. Your cert will
expire on 2022-01-27. To obtain a new version of the certificate in
the future, simply run Let’s Encrypt again.

# If you see “Congratulations,” you’ve succeeded.
# The following certificates have been obtained under [/etc/letsencrypt/live/[domain name]/] as described in the message

# cert.pem ⇒ SSL server certificate (including public key)
# chain.pem ⇒ intermediate certificate
# fullchain.pem ⇒ A file containing the concatenation of cert.pem and chain.pem
# privkey.pem ⇒ Private key to public key

2.Automatically renew certificates(Let’s Encrypt)

①Test before registration
Try to test the automatic update using the following –dry-run option.
With this option, the certificate is not renewed, but only checked, so there is no need to worry about being trapped by the limit on the number of times a certificate can be obtained.

# /usr/bin/certbot renew –dry-run

②Register crontab

# crontab -e
00 03 01 * * root /usr/bin/certbot renew && /usr/sbin/service apache2 restart

# make
# make install
# cd /usr/local/src/
# mv /lib/systemd/system/httpd.service /lib/systemd/system/httpd.service_bak2
Create a new httpd.service
# vi  /lib/systemd/system/httpd.service
