专职DBA-Linux实验环境安装部署

建立新的虚拟机
自定义（高级）配置
虚拟机硬件兼容性：Workstation 10.0
稍后安装操做系统
操做系统类型：Linux CentOS 7 64位
虚拟机名称：db01
虚拟机存放位置：D:\VM\db01
处理器数量：1
每一个处理器的核心数量：1
总处理器核心数量：1
虚拟机内存：2048 MB
第一块网卡eth0：使用网络地址转换NAT模式
第一块网卡eth1：使用网络地址转换NAT模式
第一块网卡eth2：使用网络地址转换仅主机模式
第一块网卡eth3：使用网络地址转换仅主机模式
I/O控制器类型：SCSI控制器-LSI Logic (推荐)
虚拟机磁盘类型：SCSI (推荐)
建立新的虚拟磁盘
磁盘大小：50GB  将虚拟磁盘存储为单个文件
磁盘文件命名：db01-OS-DISK-50GB-sda.vmdk
再加2块硬盘
db01-OS-DISK-50GB-sdb.vmdk  500GB    data-500GB.vmdk
db01-OS-DISK-50GB-sdc.vmdk  200GB  backup-200GB.vmdk
完成后编辑虚拟机设置
移除：USB控制器、声卡、打印机
添加一块网卡：选择网络适配器---》仅主机模式---》启动时链接---》完成
点击CD/DVD：把CentOS-7.6的iso镜像扔进去---》肯定
开机启动


鼠标点击去选中第一行，按Tab键
输入：net.ifnames=0 biosdevname=0
回车


系统的安装语言：English

时区：Asia/Shanghai

键盘：English (US)

语言支持：English、简体中文(中国)

SOFTWARE SELECTION选项：最小化安装Minimal Install（右边选项全选也行，或者就选择下面这三个也能够）
        Debugging Tools  调试工具
        Compatibility libraries  兼容性库
        Development tools  开发工具

sda分区：
选择标准分区类型
/boot  200M
/      剩余所有空间都给/

Kdump：禁用disabled

主机名设置：db01  点击应用

网卡只配置eth0
    ip:10.0.0.51
    子网掩码:255.255.255.0
    网关:10.0.0.2

安全：取消

root密码：mysql

安装完成点击：reboot


[root@db01 ~]# poweroff
编辑虚拟机设置---》CD/DVD---》取消启动时链接---》肯定
