The purpose of Cloud Linux is to improve the overall stability, reliability and performance of a shared server. Cloud Linux limits each individual account to a set amount of CPU and memory (RAM) resources. This means that rather than a server going under load and becoming slow for all users on it, only the account causing problems will be restricted. As Cloud Linux is becoming more common on shared hosting servers, it is important to know how to troubleshoot common problems that come up when using it to get the most out of your website and hosting environment.
I’ve used Cloud Linux for over a year now and think it’s great when used correctly, this article includes everything I have learned while using it during that time. A lot of users don’t like it because they have experienced it cutting the performance of their websites. With this guide you will be able to pin point issues and then work on resolving them. Although this information is aimed towards the server administrator, users within the Cloud Linux environment will find useful information for checking logs to find problems with their websites.
