21. Raise network interfaces .md

Ubuntu 无法上网，报错 Raise network interfaces

第一步

执行命令ifconfig 和 ifconfig -a

第二步

对比结果，如果ifconfig里面比ifconfig -a的内容少如下内容，那么代表你的网卡ens33没有开启,此时只需要开启即可

ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.134.128  netmask 255.255.255.0  broadcast 192.168.134.255
        inet6 fe80::20c:29ff:fe13:818e  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:13:81:8e  txqueuelen 1000  (Ethernet)
        RX packets 18249  bytes 24888390 (24.8 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 4305  bytes 293768 (293.7 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

第三步

开启已经关闭的网卡ens33

sudo ifconfig ens33 up //启用网卡，然后再通过 ifconfig -a 看，发现 没有IP

sudo dhclient ens33  // 分配IP

然后就可以开始上网了

31.mount data disk.md

Ubuntu 挂载数据盘

查看磁盘命令

df -h

如果发现有数据盘没有挂载成功，那么继续下面的操作。

查看数据盘是否存在

fdisk -l

数据硬盘分区

fdisk /dev/vdb，依次输入 n, p, 1, 回车, 回车, wq

格式化磁盘

mkfs.ext4 /dev/vdb1

挂载新分区

mount /dev/vdb1 /home/ubuntu/ason

写入fstab, 开机自动挂载

echo '/dev/vdb1 /home/ubuntu/ason ext4 defaults 0 0'  >>  /etc/fstab

检查

df -h
