近期在使用ESXI的过程中，发现了一个现象：CPU占用越来越高。
ESXI刚启动时，开启10个左右的linux和一个windows10，windows10在不工作的情况下CPU占用10%左右，工作下20%左右。然而每当使用了几天便会发现，明明没有程序在工作，CPU占用高达50%左右，并且无法降下来，只能重启ESXI。
一番查阅后得知，原来是要给系统装上VMware-Tools。windows系统由于是可视化界面，就不介绍了，记录一下linux系统安装过程。
挂载VMware Tools
在esxi虚拟机界面，勾选虚拟机，点击【操作-客户机操作系统-安装VMware Tools】
安装VMware Tools
1、ssh登录linux
2、挂载VMware Tools光盘
mkdir /cdrom
sudo mount /dev/cdrom /cdrom/
3、复制光盘内容
mkdir vmware-tools && cp -Rf /cdrom/* vmware-tools
4、解压里面的安装包
cd vmware-tools
#不同版本文件名不一样
tar -zxvf VMwareTools-10.3.21-14772444.tar.gz
5、执行安装脚本
./vmware-tools-distrib/vmware-install.pl
执行后会提示是否安装，输入【y】进行安装
而后直接一路按回车，使用默认设置即可。
以下是安装过程完整输出
