by virtual machines to run multiple "virtual servers" on a high-end server at the same time. These virtual servers are no different from the real servers. The use of the partitioning server has multiple advantages: first, the many machines formed by the partitioning system are in the same physical server, rather than scattered around, so it is much easier to man

As we all know, network security is a very important topic, and servers are the most critical link in network security. Linux is considered to be a safer Internet server. As an open-source operating system, once a security vulnerability is found in Linux, volunteers from around the world on the Internet will actively fix it. However, system administrators often cannot obtain and correct information in a timely manner, which gives hackers an opportunit
