Editor's note: Cluster SSH is a tool that can be used to manage multiple remote computers simultaneously through the SSH protocol. It is ideal for quickly configuring all computer nodes in a cluster that run the same service and have the same configuration. There are a large number of open-source management tools available for such management, such as dsh and SUSE Manager. The following describes how to use ClusterSSH to manage multiple Linux servers.

Many enterprises run multiple servers due to historical reasons or other factors, such as multiple Netware servers and multiple Windows NT servers in the telecom department. In many education departments, run multiple Netware servers to save files. After years of use, these servers
1. Using DNS Forwarders
DNS forwarders are for other DNS servers
The DNS server that completes the DNS query. The primary purpose of using DNS forwarders is to mitigate the pressure of DNS processing, to transfer query requests from DNS servers to forwarders and to benefit from DNS forwarders potentially larger DNS caches.
Another benefit of using DNS forwarders is that it prevents DNS
With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load
