CentOS 7 – allowing port 80 & 443 httpd

Easy!

Run

firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --zone=public --add-port=443/tcp --permanent

and then…

firewall-cmd --reload

 

How to check the zones?

firewall-cmd --get-zones

 

If you can’t connect to the server/page…

or with curl…

hell:~ pjrfigueiredo$ curl https://www.domain.com
curl: (7) Failed to connect to www.domain.com port 443: Connection refused

Check if anything is listening to 443

sudo netstat -lnp | grep 443

If nothing show up… try to edit the domain httpd configuration file… and make it so, that httpd is listening to it… like for example

<VirtualHost *:80 *:443>

+John Mueller Hi John, does the rating of the SSL certificate impact the ranking boost? For example does a A rating HTTPS SSL certificate give a bigger ranking boost than a B rating SSL certificate? Or as long as the SSL certificate is valid and comes from a good authority (green locker) there is no ranking boost difference on class A, A-, B, C certificates?
