Editor to share with you how to build a Hadoop pseudo-distributed system. I hope you will get something after reading this article. Let's discuss it together.

I.

Network connection mode of virtual machine and static IP setting of Linux

1. Introduction of Network connection Mode

1) Host mode only

The virtual machine is networked separately with the host, and the virtual machine cannot communicate with other machines in the host network because the network segment is different.

2) bridging mode

The virtual machine will use the network segment of the host's network, and other machines on the host's network can communicate with the virtual machine because they are in the same network segment

two。 Configure host-only mode

1) Host-side configuration: when using host-only mode, you need to configure the VMware Network Adapter VMnet1 of the host, which is the IP address and gateway

3) restart the virtual machine network card

[root@localhost Desktop] # service network restart

Shutting down loopback interface: [OK]

Bringing up loopback interface: [OK]

Bringing up interface Wired_connection_1: Active connection state: activated

Active connection path: / org/freedesktop/NetworkManager/ActiveConnection/3

[OK]

4) View virtual machine network information

[root@localhost Desktop] # ifconfig

Eth2 Link encap:Ethernet HWaddr 00:50:56:2F:E5:3A

Inet addr:192.168.80.100 Bcast:192.168.80.255 Mask:255.255.255.0

Inet6 addr: fe80::250:56ff:fe2f:e53a/64 Scope:Link

5) use virtual machines to access hosts

[root@localhost Desktop] # ping 192.168.80.1

PING 192.168.80.1 (192.168.80.1) 56 (84) bytes of data.

64 bytes from 192.168.80.1: icmp_seq=1 ttl=64 time=0.468 ms

64 bytes from 192.168.80.1: icmp_seq=2 ttl=64 time=0.277 ms

64 bytes from 192.168.80.1: icmp_seq=3 ttl=64 time=0.316 ms

64 bytes from 192.168.80.1: icmp_seq=4 ttl=64 time=0.279 ms

^ Z

[2] + Stopped ping 192.168.80.1

6) use hosts to access virtual machines

C:\ Users\ thinkpad > ping 192.168.80.100

Ping 192.168.80.100 has 32 bytes of data:

Reply from 192.168.80.100: byte = 32 time = 1ms TTL=64

Reply from 192.168.80.100: bytes = 32 time
