Scenario

This section describes how to connect to a Linux instance on a mobile device to easily connect and manage your Linux cloud server.

· In this section, taking iTerminal-SSH Telnet as an example, we will introduce how to connect to Linux instance on the iOS device. For details, see Login to Linux Cloud Server on iOS Device.

· In this section, taking JuiceSSH as an example, we will introduce how to connect to Linux instance on the Android device. For details, see Login to Linux Cloud Server on Android Device.

Prerequisites

· The Linux cloud server is in the Running state.

· Usually, the default username for Linux OS is "root", while the default username for CoreOS is "core".

· Port 22 has been opened to the inbound security group where the Linux cloud server is located.

· Linux cloud server firewall is not enabled or port 22 is released after it is enabled.

· Ensure that the login terminal used has network connectivity with the Linux cloud server. If you use a terminal on the public network to log in, you need to bind an elastic IP address to your Linux cloud server. If you use this method to log in over the Intranet, you do not need to bind the Elastic IP, such as VPN or Cloud Dedicated Access.

Login to Linux cloud server on iOS device

If you are using an iOS device, make sure that the SSH client tool is installed, let's use Termius as an example. In this example, CentOS 7.6 operating system is used, which authenticates with username and password.

1. Launch the Termius app on iOS device and click New Host.

2. On the SSH page, enter the connection information and click Save. The following connection information is required:

· Alias: Set a name for the connection, for example, ecs01.

· Hostname: Enter the public IP address of the Linux instance to which you want to connect.

· Use SSH: Ensure that the SSH login configuration is enabled.

· Host: Enter the fixed public IP or elastic IP of the Linux instance to which you want to connect.

· Port: Enter the port number "22".

· User name: Enter the username "root".

· Password: Enter the login password for the instance.

1. Click the Save button in the upper right corner to save the login information. On the Hosts page, click the name of the connection to connect to the server remotely.

2. When the Welcome Login prompt appears, you have successfully connected to the Linux cloud server.

Login to Linux cloud server on Android device

If you use an Android device, please make sure that JuiceSSH is installed. In this example, CentOS 7.6 operating system is Passed, which authenticates with username and password.

1. Start the JuiceSSH application and click Connection.

2. On the Connection page, click the Add button in the lower right corner.

3. On the New Connection page, fill in the basic and advanced settings information and save. The following information is required:

· Nickname: Specify a name for the login session, for example linux_test.

· Type: Use the default SSH.

· Address: Enter the elastic IP address of the Linux instance you want to log in to.

· Authentication: Follow the steps below to set up authentication:

o Click Authentication and then click New in the drop-down list.

o On the New Authentication page, fill in the following information and click the Confirm button in the upper right corner.

· Port: Enter the port number "22".

1. On the Connection page, click the created connection.

2. After confirming the prompt message, click Accept.

3. (Optional) When you connect for the first time, JuiceSSH may prompt you on how to set options such as font size and pop-up keyboard. Please confirm the relevant information and click Ok, I got it! .
