How Can I Obtain the IP Address of an Application?
EIPs obtained through tools are inaccurate. Therefore, applications may fail to be connected to DB instances even though you have added IP addresses to a whitelist. This section describes how to obtain IP addresses of applications.
- Add IP addresses or IP address ranges that are allowed to access DB instances to the RDS whitelist.
- Use the MySQL client to connect to an RDS MySQL DB instance.
mysql -h host_name -P port -u username -p
Enter the password of the database account if the following information is displayed:
For example, run the following command as user root to connect to a DB instance:
mysql -h 172.16.0.31 -P 3306 -u root -p
- Query process information.
Figure 1 shows the query result. The outbound IP address is the host IP address in the "show processlist" row of the Info field.
