A Brand New Tomcat is Here!

In cPanel & WHM version 76, we implemented a new version of Apache Tomcat® for users that run EasyApache 4. This iteration represents a complete overhaul of our implementation and provides substantial differences from the EasyApache 3 version.

This utilization increases security and allows the user to manage their Tomcat services, but increases memory use on the server. A Glimpse into the Process

Cloud-Based Hostname Workaround

It’s very common these days for hosting providers to offer cloud-based hosting solutions to their customers. In configuring these servers ourselves, and in interactions with our customers’ servers, an issue has come to our attention where the dhclient script does not preserve locally-configured hostnames. This means that hostnames configured on the command line might not remain through a reboot. We wante to provide a workaround solution for this while continuing to investigate a more permanent, long-term solution. What …
