This document describes how to change the instance network type and modify the instance access address.
Note:
Modifying the network configurations of an instance is highly risky. Please do so only during off-peak hours. After modification, unless assigned to another service, the original IP will remain valid for another 24 hours. We recommend modifying your business configuration accordingly as soon as possible.
Modifying the Private IP
You can modify the private IP of a TencentDB instance in VPC.
1. Log in to the TencentDB for MariaDB console, click an instance ID in the instance list, and enter the instance details page.
2. In the Basic Info section, click
next to Private IP to modify it. You can do so only when the current subnet has available IPs.
3. In the pop-up dialog box, modify the private IP and click Confirm.
Switching between VPC Subnets
You can switch an instance between VPC subnets.
1. Log in to the TencentDB for MariaDB console, click an instance ID in the instance list, and enter the instance details page.
2. In the Basic Info section, click Change Subnet next to Network.
3. In the pop-up dialog box, select a subnet, select Auto-assign IP or Specify IP, and click Comfirm.
Note:
The original VIP address remains valid for another 24 hours after the VPC is modified. Please modify your business IP address accordingly within 24 hours.
Because the product supports an intra-city active-active architecture, you are recommended to choose a VPC subnet in the same region as your business server or primary node.
Switching between VPCs
1. Log in to the TencentDB for MariaDB console, click an instance ID in the instance list, and enter the instance details page.
2. In the Basic Info section, click Change Subnet next to Network.
3. In the pop-up dialog box, select a VPC, select Auto-assign IP or Specify IP, and click Comfirm.
Note:
The original VIP address remains valid for another 24 hours after the VPC is modified. Please modify your business IP address accordingly within 24 hours.
Because the product supports an intra-city active-active architecture, you are recommended to choose a VPC subnet in the same region as your business server or primary node.
Switching from a Classic Network to a VPC
You can switch an instance from classic network to VPC.
1. Log in to the TencentDB for MariaDB console, click an instance ID in the instance list, and enter the instance details page.
2. In the Basic Info section, click Switch to VPC next to Network.
3. In the pop-up dialog box, select a VPC, select Auto-assign IP or Specify IP, and click Comfirm.
Note:
The switch from classic network to VPC is irreversible.
After the switch, VPC access will take effect immediately. The original classic network access will be retained for 24 hours; therefore, other instances associated to the TencentDB for MySQL instance should be migrated to VPC within 24 hours so as to guarantee uninterrupted access.
Because the product supports an intra-city active-active architecture, you are recommended to choose a VPC subnet in the same region as your business server or primary node.
