- CentOS 版本：CentOS-7-x86_64-DVD-1804.iso
ifconfig 命令問題
[root@localhost ~]# ifconfig
-bash: ifconfig: command not found
若 CentOS 里邊是沒有安裝 ifconfig
解決辦法：yum安裝ifconfig這個(gè)命令包
# 需要保證虛擬機(jī)能連接外網(wǎng)
yum search ifconfig
yum install net-tools.x86_64
通信問題
| NAT | Bridged Adapter | Internal | Host-only Adapter | |
|---|---|---|---|---|
| 虛擬機(jī)->主機(jī) | ?? | ?? | ? | 默認(rèn)不需要設(shè)置 |
| 主機(jī)->虛擬機(jī) | ? | ?? | ? | 默認(rèn)不需要設(shè)置 |
| 虛擬機(jī)->其他主機(jī) | ?? | ?? | ? | 默認(rèn)不需要設(shè)置 |
| 其他主機(jī)->虛擬機(jī) | ? | ?? | ? | 默認(rèn)不需要設(shè)置 |
| 虛擬機(jī)之間 | ? | ?? | 同網(wǎng)絡(luò)名下可以 | ?? |
需要的條件：主機(jī)能 ssh 連接虛擬機(jī)，虛擬機(jī)能連接外網(wǎng)
- 網(wǎng)卡1：橋接網(wǎng)絡(luò)
- 網(wǎng)卡2：網(wǎng)絡(luò)地址轉(zhuǎn)換(NAT)
