部署redis集群
注意：master和slave不能是同一台服务器的两个端口
环境：
三台服务器：A、B、C
6379：master
6380：slave
A：IP：192.168.100.11，port：6379、6380
B：IP：192.168.100.12，port：6379、6380
C：IP：192.168.100.11，port：6379、6380

可以看到memcached高可用正常
安装 Vmware esxi
基于vmware workstation虚拟机运行vmware esxi，安装两台esxi服务器，IP地址分为是192.168.126.128/129
稍后指定操作系统
选择esxi版本（因为我们装的是7.0没有，所以就选择了6.x）
选择保存的位置
选择磁盘容量
自定义硬件
配置内存
配置处理器数量，开启虚拟化（不开启后期会报错）
选择镜像
开始安装esxi节点
加载内核
加载驱动
确认安装
同意协议，按F11
扫描可用硬盘
选择硬盘并安装
设置管理员密码
开始安装
安装过程中
安装完成
配置IP地址：将服务器配置为静态IP地址，当前为DHCP获取的IP地址。
配置界面进程登录，按F2进行登录
登录服务器
输入安装过程中管理员密码，管理员账号为root，密码为安装过程中设置的密码
配置静态IP地址：
当前为DHCP获取的IP地址
更改IP地址为静态IP地址、配置DNS并重启网络服务
输入Y保存
至此vmware esxi安装和配置基本完成。
