This topic describes how to purchase and use Linux KEC instances, including purchase, login, and data disk mounting.
Log in to the KEC instance console.
On the Instance page that appears, click Create Instance.
In the Basic Configuration step, select a Linux image, complete relevant configuration, and then click Next.
In the Network Configuration step, set Bind EIP to Buy New EIP or Purchase EIP Later in the EIP Console. Note that the number of EIPs to be purchased must be the same as the number of KEC instances.

A Linux KEC instance supports WebVNC login and SSH login.
The default username is ubuntu for the Ubuntu operating system and root for all other Linux operating systems. If you forget the password, you can reset the password in the console.
Log in to the KEC instance console.
On the Instance page that appears, find the instance that you want to log in, and click Connect Instance in the Operation column. Note that the instance must be in the Running state.
Before you log in to an instance by using SSH, add an inbound rule in which port 22 is enabled to the security group to which the instance belongs. For more information about how to configure a security group, see Configure a security group.
This example uses the PuTTY tool in Windows as the SSH client.
Start the PuTTY tool.
Set the following parameters in the PuTTY Configuration dialog box:
Click Open.
Run the fdisk -l command to view the data disks mounted to the KEC instance.

b. Enter n to create partitions.
c. Enter p to create a single partition or e to create multiple partitions.
d. Enter the partition number. Value values: 1 to 4.
e. Select the first sector of the partition. If you press the Enter key, the value 2048 is used by default.
f. Select the last sector of the partition. If you press the Enter key, the maximum value is used by default.
g. Enter w to complete partitioning and exit.

Run the mount /dev/vdb1 /data command to manually mount the data disk vdb to the mount point data.
