專職DBA-Linux實驗環境安裝部署

專職DBA-Linux實驗環境安裝部署

建立新的虛擬機
自定義（高級）配置
虛擬機硬件兼容性：Workstation 10.0
稍後安裝操做系統
操做系統類型：Linux CentOS 7 64位
虛擬機名稱：db01
虛擬機存放位置：D:\VM\db01
處理器數量：1
每一個處理器的核心數量：1
總處理器核心數量：1
虛擬機內存：2048 MB
第一塊網卡eth0：使用網絡地址轉換NAT模式
第一塊網卡eth1：使用網絡地址轉換NAT模式
第一塊網卡eth2：使用網絡地址轉換僅主機模式
第一塊網卡eth3：使用網絡地址轉換僅主機模式
I/O控制器類型：SCSI控制器-LSI Logic (推薦)
虛擬機磁盤類型：SCSI (推薦)
建立新的虛擬磁盤
磁盤大小：50GB  將虛擬磁盤存儲爲單個文件
磁盤文件命名：db01-OS-DISK-50GB-sda.vmdk
再加2塊硬盤
db01-OS-DISK-50GB-sdb.vmdk  500GB    data-500GB.vmdk
db01-OS-DISK-50GB-sdc.vmdk  200GB  backup-200GB.vmdk
完成後編輯虛擬機設置
移除：USB控制器、聲卡、打印機
添加一塊網卡：選擇網絡適配器---》僅主機模式---》啓動時鏈接---》完成
點擊CD/DVD：把CentOS-7.6的iso鏡像扔進去---》肯定
開機啓動


鼠標點擊去選中第一行，按Tab鍵
輸入：net.ifnames=0 biosdevname=0
回車


系統的安裝語言：English

時區：Asia/Shanghai

鍵盤：English (US)

語言支持：English、簡體中文(中國)

SOFTWARE SELECTION選項：最小化安裝Minimal Install（右邊選項全選也行，或者就選擇下面這三個也能夠）
        Debugging Tools  調試工具
        Compatibility libraries  兼容性庫
        Development tools  開發工具

sda分區：
選擇標準分區類型
/boot  200M
/      剩餘所有空間都給/

Kdump：禁用disabled

主機名設置：db01  點擊應用

網卡只配置eth0
    ip:10.0.0.51
    子網掩碼:255.255.255.0
    網關:10.0.0.2

安全：取消

root密碼：mysql

安裝完成點擊：reboot


[root@db01 ~]# poweroff
編輯虛擬機設置---》CD/DVD---》取消啓動時鏈接---》肯定
