Installing Edge for Linux

Preparations

• Prepare a Linux server for installing Edge in the source intranet environment. The Linux server must:
  • Be able to access the Internet and the domain names of MgC and IoTDA. For details about the domain names to be accessed, see Public Domain Names.
  • Allow outbound traffic on 8883 if the server is in a security group.
  • Run CentOS 8.X.
  • Have at least 4 CPUs and 8 GB of memory. If you want to use big data verification, the server must have at least 8 CPUs and 16 GB of memory.
  

  Do not install Edge on a source server to be migrated.

  • High resource consumption: Edge consumes CPU and memory resources during collection and migration. If a large number of migration tasks are performed by Edge, services on the source server may be affected.
  • Port occupation: Edge occupies some ports on the source server, which may affect services on the server.
• Run the following command to check whether rng-tools is installed on the Linux server where the Edge is installed:

  rpm -qa | grep rng-tools

  If no rng-tools-related information is displayed, rng-tools is not installed on the server. Run the following command to install rng-tools:

  yum -y install rng-tools

• Disable any antivirus and protection software on the Linux server where Edge is installed. This type of software may stop Edge from executing migration commands, resulting in migration failures.
• Add an inbound rule to the security group of the Linux server to allow TCP traffic on port 27080. Set the source address to the IP address of the Windows server you use to log in to the Edge console.

  

• Sign up for a HUAWEI ID and enable Huawei Cloud services, and obtain an AK/SK pair for the account.
• Create a migration project on the MgC console.

Procedure

1. Sign in to the MgC console from the Linux server you prepared.
2. In the navigation pane on the left, choose Tools.
3. In the Linux area, click Download Installation Package or Copy Download Command to download the Edge installation program to the Linux server.
4. Decompress the Edge installation package.

   tar zxvf Edge.tar.gz

5. Go to the scripts directory in the decompressed Edge directory.

   cd Edge/scripts/

6. Run the Edge installation script.

   ./install.sh

7. Enter a private IP address of the Linux server, and the IP address will be used for accessing the Edge console. If the entered IP address is not used by the Linux server, the system prompts you whether to use any public IP address of the Linux server as the Edge access address.

   

8. Check if the message shown in the following figure is displayed. If it is, the Edge for Linux has been installed. The port in the following figure is for reference only. Note the actual port returned. Generally, the port is 27080.

   

   Update environment variables.

   source /etc/profile

9. On the Windows server for which an inbound rule is added to the security group of the server where Edge is installed, open a browser and enter https://IP address entered in Step 7:Port obtained in Step 8 in the address box to access the user registration page of Edge. For example, if the IP address entered in step 7 is 192.168.x.x and the port returned in step 8 is 27080, the Edge access address is https://192.168.x.x:27080.
   

   If there are access problems, check the IP address entered in the address box and the inbound rule settings of the security group of the Linux server with Edge installed.

Registering an Account

When you log in to the Edge console for the first time, you must set a username and password. Keep the username and password secure.

1. On the Register page, specify a username and password, confirm the password, and click Privacy Statement.

   

2. Read the privacy statement carefully before selecting I have read and agree to the Privacy Statement, and click Register. Then you need to connect the Edge device to MgC. For details, see Connecting the Edge Device to MgC.
