Failed to start The Apache HTTP Server. (98)Address already in use: AH00072: make_sock: could not bind to address [::]:443
Using netstat command check to find out what is consuming port 443
# netstat -tulpn | grep 443
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 1508/sshd
tcp6 0 0 :::443 :::* LISTEN 1508/sshdNotice the process ID that are assigned
You can restart sshd to verify
# service sshd restart
# netstat -tulpn | grep 443
tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 13748/sshd
tcp6 0 0 :::443 :::* LISTEN 13748/sshd
# ps -ef | grep sshd
root 13748 1 0 14:06 ? 00:00:00 /usr/sbin/sshd -D
root 13763 13248 0 14:06 pts/0 00:00:00 grep --color=auto sshd
Now that we confirmed the process ID that is consuming port 443, kill -9 PID
# netstat -tulpn | grep 443Notice there is nothing consuming port 443, now start httpd
# systemctl restart httpd
# ps -ef | grep http
