Cloud Deployment

This document mainly introduces the cloud deployment of TuGraph, and you can also refer to theAlibaba Cloud ComputeNest deployment document.。

1.Introduction

TuGraph (tugraph.antgroup.com) is a high-performance graph database of Alibaba Group. TuGraph provides community version services on ComputeNest, so you can quickly deploy TuGraph services on ComputeNest and achieve operation and maintenance monitoring, thereby building your own graph application. This document introduces how to open TuGraph community version services on ComputeNest, as well as deployment process and usage instructions.

2.Instance Description

TuGraph is deployed as a community open source version, and the source code can be found in the Github Repo. Currently, the available instance specifications are as follows:

Instance Family

vCPU and Memory

System Disk

Public Bandwidth

ecs.r7a.xlarge

AMD Memory r7a, 4vCPU 32GiB

ESSD Cloud Disk 200GiB PL0

Fixed bandwidth of 1Mbps

ecs.r6.xlarge

Memory r6, 4vCPU 32GiB

ESSD Cloud Disk 200GiB PL0

Fixed bandwidth of 1Mbps

Estimated costs can be seen in real time when creating instances (currently free). If you need more specifications or other services (such as cluster high availability requirements, enterprise-level support services, etc.), please contact us at tugraph@service.alipay.com.

3.Deployment Process

3.1.Preparation

Before starting to use, you need an Alibaba Cloud account to access and create resources such as ECS and VPC.

  • If you use a personal account, you can directly create a service instance.

  • If you create a service instance using a RAM user and use Alibaba Cloud ComputeNest for the first time:

    • Before creating a service instance, you need to add permissions for the corresponding resources to the account of the RAM user. For detailed operations on adding RAM permissions, please see Grant RAM user permissions. The required permissions are shown in the following table.

    • Authorization to create associated roles is also required. Refer to the following figure and select Agree to authorize and create associated roles.

Currently supports ecs.r6.xlarge and ecs.r7a.xlarge specifications.

ECS Instance Configuration

Instance Password

**

Set the instance password. Length of 8-30 characters, must include three items (uppercase letters, lowercase letters, numbers, special characters in ()`~!@#$%^&*_-+={}[]:;’<>,.?/).

3.4.2.Specific Steps

The creation of the service is carried out according to the following steps, refer to the figure below:

  • Create an instance name, such as “test” in the figure below

  • Select the region, such as “China East 1 (Hangzhou)” in the figure below

Create Instance

  • Select the instance type, currently supports ecs.r6.xlarge and ecs.r7a.xlarge specifications. If there is no model available in the list, try selecting other deployment areas.

  • Select the model

  • Configure the password for the instance

  • Select the deployment area, such as “Availability Zone I” in the figure below

Select Region

  • Click next to enter the order confirmation page

  • Check the checkboxes for “Permission Confirmation” and “Service Terms”

  • Click the green “Start Free Trial” button in the lower left corner to create a service instance

Confirmation

3.5.Start TuGraph Service

  • View the service instance: After the service instance is created successfully, it takes about 2 minutes for deployment. After the deployment is complete, you can see the corresponding service instance on the page, as shown in the figure below.

View Instance

  • Click the service instance to access TuGraph. After entering the corresponding service instance, you can get 3 ways to use it on the page: web, rpc, ssh. You can also see the password of user admin on the page.

Access Method

  • Click the link of web to jump to the deployed TuGraph Web. It is recommended that novice users first use the demo to quickly get started with TuGraph.

    • First, on the TuGraph Web login page, enter the default username (admin) and the password on the page to log in, as shown in the figure below.

    • After the login is completed, click “New Instance” -> “Create Instance” in sequence, wait for the creation to be completed, and the steps in 3 will change to green in turn, and it will automatically switch to the subgraph MovieDemo1, as shown in the figure below.

4.Common FAQs

No available resources in the selected deployment area

Sometimes, the selected deployment area (such as Availability Zone G) does not have available resources for the selected package, and an error will be reported as shown in the figure below.

Deployment Error

Solution:Try selecting other regions, such as Availability Zone I

Unaccessible to the web port

It takes some time for the server to get ready. Just wait for a few seconds.
