Connecting to a GeminiDB Influx Instance Using the InfluxDB CLI over a Private Network

Scenarios

This section uses Linux as an example to describe how to connect to a GeminiDB Influx instance using a load balancer address or the private IP address of an ECS.

Usage Notes

The instance and ECS must be in the same VPC and subnet.
The ECS must be allowed by the security group to access the instance.
- If the instance is associated with the default security group, you do not need to set security group rules.
- If the instance is not associated with the default security group, check whether the security group rules allow the ECS to access the instance. For details, see Setting Security Group Rules for a GeminiDB Influx Instance.

Prerequisites

An ECS has been created. The following uses a Linux ECS as an example. For details, see Purchasing an ECS in Getting Started with Elastic Cloud Server.
Download the x86 client or Arm client of InfluxDB. The following uses the Linux 64-bit client as an example.

Log in to the ECS. For details, see Logging In to an ECS in Getting Started with Elastic Cloud Server.
Upload the InfluxDB client installation package to the ECS using file transfer tools like XFTP.
Decompress the client (for example, x86 client) tool package.
```
tar -xzf influxdb-1.8.10_linux_amd64.tar.gz
```

Connect to your instance in the directory where the InfluxDB client is located.

Run the following command to go to the InfluxDB directory:
```
cd influxdb-1.8.10-1/usr/bin
```

Connect to the GeminiDB Influx instance.

./influx -ssl -unsafeSsl -username '<DB_USER>' -password '<DB_PWD>' -host <DB_HOST> -port <DB_PORT>

Example:

./influx -ssl -unsafeSsl -username 'rwuser' -password '<DB_PWD>' -host 192.xx.xx.xx -port 8635

**Table 1** Parameters
Parameter	Description
<DB_USER>	Username of the administrator account. The default value is rwuser. On the Instances page, click the instance name. In the DB Information area on the Basic Information page, you can see the administrator username.
<DB_PWD>	Administrator password
<DB_HOST>	Load balancer address of the instance to be connected. Connecting to an instance using a load balancer address is now in OBT. To use it, choose Service Tickets > Create Service Ticket in the upper right corner of the console and contact the customer service. Scenario 1: If you have obtained a load balancer address before creating an instance, the load balancer address is selected by default on the instance creation page. After the instance is created, click its name to go to the Basic Information page and obtain the load balancer IP address in the Network Information area. Scenario 2: To use a load balancer address after the instance is created, choose Service Tickets > Create Service Ticket in the upper right corner of the console and contact the customer service. Then you can click the instance name to view the load balancer address in the Network Information area on the Basic Information page.
<DB_PORT>	Instance port Click the instance name to go to the Basic Information page. In the Network Information area, you can see the instance port.

Check the results. If information similar to the following is displayed, the connection is successful.
```
Connected to https://host:port version x.x.x
InfluxDB shell version 1.8.10
>
```

Log in to the ECS. For details, see Logging In to an ECS in Getting Started with Elastic Cloud Server.
Upload the InfluxDB client installation package to the ECS using file transfer tools like XFTP.
Decompress the client (for example, x86 client) tool package.
```
tar -xzf influxdb-1.8.10_linux_amd64.tar.gz
```

Connect to your instance in the directory where the InfluxDB client is located.

Run the following command to go to the InfluxDB directory:
```
cd influxdb-1.8.10-1/usr/bin
```

Connect to the GeminiDB Influx instance.

./influx -username '<DB_USER>' -password '<DB_PWD>' -host <DB_HOST> -port <DB_PORT>

Example:

./influx -username 'rwuser' -password '<DB_PWD>' -host 192.xx.xx.xx -port 8635

**Table 2** Parameters
Parameter	Description
<DB_USER>	Username of the administrator account. The default value is rwuser. On the Instances page, click the instance name. In the DB Information area on the Basic Information page, you can see the administrator username.
<DB_PWD>	Administrator password
<DB_HOST>	Load balancer address of the instance to be connected. Connecting to an instance using a load balancer address is now in OBT. To use it, choose Service Tickets > Create Service Ticket in the upper right corner of the console and contact the customer service. If you have enabled the load balancer address before creating an instance, you can view that the load balancer address is selected by default on the instance creation page. After the instance is created, click the instance name to go to the Basic Information page and obtain the load balancer address in the Network Information area. If you have already created an instance and enabled the load balancer address, you can click the instance name and view the address in the Network Information area on the Basic Information page.
<DB_PORT>	Instance port Click the instance name to go to the Basic Information page. In the Network Information area, you can see the instance port.

Check the results. If information similar to the following is displayed, the connection is successful.
```
Connected to https://host:port version x.x.x
InfluxDB shell version: 1.8.10
>
```

Log in to the ECS. For details, see Logging In to an ECS in Getting Started with Elastic Cloud Server.
