To guarantee database security and stability, ApsaraDB for MongoDB automatically adds the IP address 127.0.0.1 to the whitelist after an instance is created. Therefore, after you create an instance, add the IP addresses or segments that need to access the database to the whitelist. Otherwise, you cannot view the instance connection address on the Basic Information page of the instance. MongoDB allows you to add up to 1,000 IP addresses.
Note: Before using a target instance, you must modify the whitelist.
Log on to the MongoDB console and locate the target instance.
Click the instance ID or Manage to go to the Basic Information page.
Click Security Control to go to the Security Control page.
You can select Manually Modify or Import ECS Intranet IP to set the IP whitelist.
Click Manually Modify to manually enter IP addresses or segments, and click OK.
Click Import ECS Intranet IP. The system displays the ECS intranet IP addresses under the same account. You can select an ECS intranet IP address, add it to the whitelist, and click OK.
Separate the IP addresses by commas (,). You can add up to 1,000 unique IP addresses/segments. Supported IP address formats include 0.0.0.0/0, 10.23.12.24 (IP), and 10.23.12.24/24 (CIDR mode; classless inter-domain routing; /24 indicates the length of the prefix in the IP address; the prefix length ranges from 1 to 32).
0.0.0.0/0 and a blank field indicates that no IP access limits are in place. In this case, the database may have a high security risk. We recommend that you set the access permission only for the Internet IP addresses/segments of your Web server.
Using the whitelist correctly can enhance access security protection for MongoDB. We recommend that you regularly maintain the whitelist.
In the future, you can select Manually Modify or Import ECS Intranet IP to set the IP whitelist.
