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：

B：IP：192.168.100.12，port：6379、6380
C：IP：192.168.100.11，port：6379、6380编译安装

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。
redis集群、memcached高可用、vmware esxi
