| − | IMPORTANT NOTES:
| |
| − | - Congratulations! Your certificate and chain have been saved at:
| |
| − | /etc/letsencrypt/live/asmith15.ops345.ca/fullchain.pem
| |
| − | Your key file has been saved at:
| |
| − | /etc/letsencrypt/live/asmith15.ops345.ca/privkey.pem
| |
| − | Your cert will expire on 2022-02-16. To obtain a new or tweaked
| |
| − | version of this certificate in the future, simply run certbot
| |
| − | again. To non-interactively renew *all* of your certificates, run
| |
| − | "certbot renew"
| |
| − | - Your account credentials have been saved in your Certbot
| |
| − | configuration directory at /etc/letsencrypt. You should make a
| |
| − | secure backup of this folder now. This configuration directory will
| |
| − | also contain certificates and private keys obtained by Certbot so
| |
| − | making regular backups of this folder is ideal.
| |
| − | - If you like Certbot, please consider supporting our work by:
| |
| − | | |
| − | Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate
| |
| − | Donating to EFF: https://eff.org/donate-le
| |
| − | | |
| − | You have new mail in /var/mail/root
| |
| − | | |
| − | root@p51:/home/andrew# cp /etc/letsencrypt/live/asmith15.ops345.ca/cert.pem ~andrew/prog/seneca/ops345/new/keys/asmith15.ops345.ca.cert.pem
| |
| − | root@p51:/home/andrew# cp /etc/letsencrypt/live/asmith15.ops345.ca/privkey.pem ~andrew/prog/seneca/ops345/new/keys/asmith15.ops345.ca.key.pem
| |
| − | root@p51:/home/andrew# chown andrew ~andrew/prog/seneca/ops345/new/keys/asmith15.ops345.ca.*
| |
| − | root@p51:/home/andrew# exit
| |
| − | </source>
| |
| − | * The file in /etc/letsencrypt/live/asmith15.ops345.ca/cert.pem is what a CA would send you after you paid them. This one is free but it expires in 90 days, which is good enough for this course.
| |
| − | * Get Apache to use the key:
| |
| − | ** /etc/httpd/conf/httpd.conf ServerName asmith15.ops345.ca:80
| |
| − | ** yum install mod_ssl
| |
| − | ** scp -P 2211 -i keys/ssh/ops345-all-aws-machines.pem keys/asmith15.ops345.ca.* andrew@34.202.103.43:~
| |
| − | ** [root@www andrew]# cp asmith15.ops345.ca.cert.pem /etc/pki/tls/certs/
| |
| − | ** [root@www andrew]# cp asmith15.ops345.ca.key.pem /etc/pki/tls/private/
| |
| − | ** /etc/httpd/conf.d/ssl.conf
| |
| − | *** SSLCertificateFile /etc/pki/tls/certs/asmith15.ops345.ca.cert.pem
| |
| − | *** SSLCertificateKeyFile /etc/pki/tls/private/asmith15.ops345.ca.key.pem
| |
| − | ** restart apache, confirm no errors
| |
| − | * Edit ops345sgprivate, add https
| |
| − | * Edit ops345sg, add https
| |
| − | * On router: iptables -t nat -I PREROUTING 2 -p tcp --dport 443 -j DNAT --to 10.3.45.11:443
| |
| − | * On www: iptables -I INPUT 4 -p tcp --dport 443 -j ACCEPT
| |
| − | * Test with firefox https. www gives a warning because the certificate is not for that FQDN. fix it for homework.
