sort_buffer_size– If you only have a few simple queries, then you don't need to increase the value of it, although you have 64GB of RAM. Bad luck may degrade performance.Query_cache_size-query buffering is often used to buffer the results of a SELECT and to no longer perform direct return results the next time the same query is made. Opening query buffering can greatly improve server speed if you have a large number of the same queries and rarely m
purposes of this article, we'll only be using a single server to keep things simple (though redundancy wowould always call for a second or a backup server ). we will utilize the following hardware configuration:

Suddenly receiving requirements from the boss, we need to deploy KVM on the servers of the existing data center so that the internal network testing machine can reach the Internet for testing. To be honest, it is a headache because our hardware resources are too short (small companies ...), there is only GB of space left, so I have to run two virtual machines on top, and I have to deal with the increasing data at the moment. This makes me speechless... hadoop is on
