Lesson four: Linux Cloning and server login (ii)

1, the Linux server can clone the virtual machine, so that two convenient operation, the cloning steps are as follows:

Open the virtual machine---Right-click-Manage = = Clone: To the following interface:

Clone the current state of the virtual machine:

Create a complete clone to facilitate later operation:

3. Show cloning Progress:

4. Cloning is complete at this time:

5. After cloning, you need to modify the IP address to log in.

2. Log in between Linux servers: a machine and a B machine, for example.

First run ssh-keygen-t RSA on a machine for three consecutive returns after generating the public and private keys, as follows:

2. Public key and secret key in/root/.ssh/directory:

3, at this time need to put id_rss.pub public key content on the B server, placed in the/root/.ssh/authorized_keys file.

[email protected]. ssh]# scp-p 52588 ~/.ssh/id_rsa.pub [email protected]:.ssh/id_rsa.pub

The command is to replicate the local public key to the remote/root/.ssh directory, but you need to enter the password:

4. Log on to the B machine at this time:

Cat/root/.ssh/id_rsa.pub >>/root/.ssh/authorized_keys

Indicates that the contents of the id_rsa.pub are appended to the redirect file.

Note: In order to not affect the use of the previous key, you must append OH.

650) this.width=650; "Src=" Https://s5.51cto.com/oss/201710/24/db5027874ae519c0be33674f58c9a61c.png-wh_500x0-wm_3 -wmp_4-s_3224763457.png "title=" 8.png "alt=" Db5027874ae519c0be33674f58c9a61c.png-wh_ "/>

5, at this time can use: Return to a machine, directly through ssh-p 52588 [email protected] login.

After testing, you can log in.
