### 1.安装下载 VMware ###

Vmware 只需要翻墙在官网注册一个号码就可以有密钥了。

个人免费版下载网址：[https://dl.iplaysoft.com/files/5378.html][https_dl.iplaysoft.com_files_5378.html]  
进去之后一直往下拉，拉到下图位置。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 1]

然后一步一步注册之后，就可以获得一个唯一的密钥。（网站进不去的话你懂得）

### 2.下载镜像 ###

Centos7 阿里云镜像下载：http://mirrors.aliyun.com/centos/7/isos/x86\_64/

### 3.安装镜像 ###

拖动镜像到框中，继续

继续

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 3]

传统的就行，继续

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 4]

自定设置—>改名字–>存储

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 5]

内存和硬盘按自己需要配置，我的电脑是16GB运存 512GB固态的，虚拟机我分别配了1GB和20GB，其他的不需要配置，配置完成关掉点启动

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 6]

键盘上下方向键控制选择第一个，回车

等待安装，出现下边界面，选择语言即可

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 8]

去掉所有黄点，开始安装,软件选择可以选一些常用的开发工具

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 9]

设置root密码之后等待安装完成，提示完成，然后重启就可以了。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 11]

接着一直前进，隐私可以关闭

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 12]

就配置成功并开机了。

### 4.配置网络互通 ###

打开终端，输入：

ifconfig

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 13]

可以看到没有IP地址信息，我们打开网络适配器需要配一下网络，来实现网络互通。

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 14]

改为WI-FI连接后，为了以后虚拟机互通搭建集群，所以需要借助**dhclient**来固定IP地址

su root
    
    dhclient

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 15]

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 16]

这样就有IP地址了，为了防止IP地址变化，配到网卡里去，配成静态地址。

修改文件：

vim /etc/sysconfig/network-scripts/ifcfg-ens33

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 17]

回车

之前的文件：

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM3Nzk2MDE3_size_16_color_FFFFFF_t_70_pic_center 18]

改完之后：

TYPE=Ethernet
    PROXY_METHOD=none
    BROWSER_ONLY=no
    BOOTPROTO=static
    DEFROUTE=yes
    IPV4_FAILURE_FATAL=no
    IPV6INIT=yes
    IPV6_AUTOCONF=yes
    IPV6_DEFROUTE=yes
    IPV6_FAILURE_FATAL=no
    IPV6_ADDR_GEN_MODE=stable-privacy
    NAME=ens33
    UUID=cfba7500-f76d-4cba-b562-deeb9de85a1c
    DEVICE=ens33
    ONBOOT=yes
    IPADDR=192.168.31.236
    NETMASK=255.255.255.0
    GATEWAY=192.168.31.1
    DNS1=119.29.29.29

:wq. //退出并保存

然后重启网卡：

systemctl restart network.service

检查一下是否能ping的通客户机，外网，其他虚拟机等。

到这里就成功配置好一台服务器了，模仿着可以在配置多台不同IP的虚拟机，形成一个小集群。
