<p><b>New page</b></p><div>Configuring Certificate for Renewal<br />
-----------------------------------<br />
<br />
<br />
Login to nagios.apoyar<br />
<br />
<br />
Copy b2b.bleckmann.com.key file to nagios from phobos.apoyar<br />
<br />
<br />
• scp neal@phobos:/home/neal/b2b.bleckmann.com.key ./<br />
<br />
<br />
<br />
Note:- If getting error while copying, need to change permission of that file on phobos.apoyar<br />
<br />
<br />
• chmod 444 b2b.bleckmann.com.key<br />
<br />
<br />
then copy same key file to returns server (bleckmann live)<br />
<br />
<br />
• scp b2b.bleckmann.com.key returns@10.208.192.174:/home/returns/<br />
<br />
<br />
After this move crt file from returns server to nagios and then to phobos using below commands<br />
<br />
<br />
• scp returns@10.208.192.174:/home/returns/b2b.bleckmann.com.crt ./<br />
<br />
<br />
• scp b2b.bleckmann.com.crt neal@phobos:/home/neal/<br />
<br />
<br />
<br />
<br />
Login to phobos.apoyar<br />
<br />
<br />
Now, we have crt, csr and key at /home/neal/certs/ on phobos.apoyar<br />
<br />
<br />
Now go to <br />
<br />
<br />
• cd /home/neal/certs/generated/bleckmann<br />
<br />
<br />
move all three files here<br />
<br />
<br />
• mv /home/neal/certs/b2b.blecmann.com* ./<br />
<br />
<br />
and then remove key file from nagios<br />
<br />
<br />
Now, login to returns server<br />
<br />
<br />
Compare crt and key file with below command<br />
<br />
<br />
• openssl x509 -noout -modulus -in b2b.bleckmann.com.crt | openssl md5 && openssl rsa -noout -modulus -in b2b.bleckmann.com.key | openssl md5<br />
<br />
<br />
<br />
Now, move crt & key to below path<br />
<br />
<br />
• mv b2b.blecmann.com.crt /etc/ssl/certs/<br />
<br />
<br />
• mv b2b.blecmann.com.key /etc/ssl/private/<br />
<br />
<br />
<br />
Note:- If getting error while moving either crt or key, check for owner and permission and change if needed with below commands<br />
<br />
<br />
• chown root:root filename<br />
<br />
<br />
• chmod 400 filename<br />
<br />
<br />
<br />
Then go to <br />
<br />
<br />
• Cd /etc/nginx/sites-available <br />
<br />
<br />
Here, search for website configuration file with below command<br />
<br />
<br />
• grep –rmv ‘/etc/nginx/sites-available/’ –e ‘b2b.bleckmann.com’<br />
<br />
<br />
then edit that conf file<br />
<br />
<br />
• vi b2b.conf<br />
<br />
<br />
change crt and key file path in conf file<br />
<br />
save and exit file<br />
<br />
<br />
• :wq!<br />
<br />
<br />
Note:- Repeat above steps of editing .conf file, if we have multiple domains<br />
<br />
<br />
<br />
Then check for any errors with below command<br />
<br />
• nginx –t<br />
<br />
<br />
and then reload nginx (DON’T RESTART)<br />
<br />
• systemctl reload nginx<br />
<br />
<br />
At last, browse websites and verify those padlocks and certificate information</div>
