There are a number of very useful tools available for Linux administrators to choose from. Here, I'm just enumerating 5 of the tools that Linux administrators need to use in their day-to-day operations. I think that the most powerful tools may not be appropriate for your use, and there are certain tools I forgot to count them in, and if so, I implore you to write down the tools I didn't include in the comments.

Earlier, we were already running Hadoop on a single machine, but we know that Hadoop supports distributed, and its advantage is that it is distributed, so let's take a look at the environment. Here we use a strategy to simulate the environment. We use three Ubuntu machines, one for the master and the other two for the slaver. At the same time, this host, we use the first chapter to build a good environment. We use the steps similar to the first chapter to operate: 1, the operating environment to take ...
