It's time for a big holy lecture. I believe that the network is essential for every operator and developer to get in touch today, we're talking about the three virtual machines in VM virtual machines divide two LAN to realize the interconnection of different local area networks that is, the AC through the B host is communicating with each other instead of through the network. Here are the requirements and topics
Routing Configuration Practices:
01. Network Information for the server needs to be configured according to the topology
02. Need to have Linux server 01 access to Linux Server 03, via Linux server 02
Transform Linux server 02 into a single router
03. Implement test methods that linux01 and linux03 can access each other, and prove that the host is interoperable through traceroute
Description: Implement the route configuration project practice according to the route command above
Let's take a look at this diagram to get the following information
A machine: 10.0.0.10/2
Gateway: 10.0.0.254
Machine B: 10.0.0.11/24
Gateway: 10.0.0.254
10.0.1.11/24
Gateway: 10.0.1.254
C Machine: 10.0.1.11/24
Gateway: 10.0.1.254
The first idea to do this question is
First processing of the source host we need a small white machine to avoid conflicts such as Mac if you directly clone your current machine you will be in the clone of the network card after the restart to find Mac error specific errors you can try
Do three ABC three virtual machines here to connect clones
modifying virtual networks for VMS
Networks for ABC, respectively
Make a Xshell connection
Renamed
Perform test processing
One: processing the source host
Before cloning in
Use the following command
Vim/etc/sysconfig/network-scripts/ifcfg-eth0
The two lines of the MAK address and UUID are removed from the
The effect after deletion
[Email protected] ~]# >/etc/udev/rules.d/70-persistent-net.rules
Immediately after emptying this file to execute the above command without an error is correct
This is a network rule configuration file
[[email protected] ~]# echo ' >/etc/udev/rules.d/70-persistent-net.rules ' >>/etc/s ' >>/etc/rc.local
Then write this command to
This is to write the above command to boot from
[Email protected] ~]# shutdown-h now
Shutdown for cloning
The operation on the source host is here.
Two VM handling 1 we're cloning.
Right-click the server you want to clone select Manage clones
2 operations on the Virtual network editor
The arrows are not the same place please follow my instructions
Operation on B
Operation on C machine
Operations on Virtual machines 1 to a host
For b Operations
New eth1
3 to C machine
Three-to-whole network optimization
The establishment of a network segment for a host
Network segment effective
Modify B to make the second NIC effective
Here's the command.
Vim/etc/sysctl.conf
This file is changed from 9 lines 0 to 1
Let's make the changes take effect now
Set the C
If this does not set it will produce a to C send data but no reply so to set
Network segment effective
Five successes of the horn
Thank you for reading this studio's documentation for your understanding of this document please contact this studio staff
This document has a pit attentive little buddy will find so please check carefully
Here's a question for you. Whether the UUID and Mac that you just started removing will be considered in the post-generation
