Symptoms
- Billing control panel and online store are not accessible.
The httpd service restart fails with the following message:
Address already in use: make_sock: could not bind to address [::]:443
Cause
One of the reasons can be that when performing the yum update operation on the OA Billing Application node, the mod_ssl package can be updated. This can result in modification of the `/etc/httpd/conf.d/ssl.conf' file, which will break the configuration of the Billing Application.
Resolution
- Connect to the Billing Application node via ssh as root.
Delete the
ssl.conf
file in the/etc/httpd/conf.d/
directory:# rm -f /etc/httpd/conf.d/ssl.conf
Create the
/etc/httpd/conf.d/ssl.conf
directory to prevent such issues in future.# mkdir /etc/httpd/conf.d/ssl.conf
Restart the httpd service:
# service httpd restart
