Using CLI to Connect to a FlexusRDS Instance
Scenarios
You can connect to your DB instance using the MySQL command-line interface (CLI) from a FlexusX instance with a MySQL client installed.
FlexusX instances and FlexusRDS instances in the same region are in the same VPC, subnet, and security group by default and can communicate with each other.
Procedure
- Log in to the FlexusX instance in the same region as your FlexusRDS DB instance.
- Download the MySQL client installation package for Linux to the FlexusX instance. The package mysql-community-client-5.7.38-1.el6.x86_64.rpm is used as an example.
wget https://dev.mysql.com/get/mysql-community-client-5.7.38-1.el6.x86_64.rpm
NOTE:A MySQL client running a version later than that of the FlexusRDS DB instance is recommended.
- Install the MySQL client.
rpm -ivh --nodeps mysql-community-client-5.7.38-1.el6.x86_64.rpm
NOTE:- If any conflicts occur during the installation, add the replacefiles parameter to the command and install the client again.
rpm -ivh --replacefiles mysql-community-client-5.7.38-1.el6.x86_64.rpm
- If a message is displayed prompting you to install a dependent package during the installation, add the nodeps parameter to the command and install the client again.
rpm -ivh --nodeps mysql-community-client-5.7.38-1.el6.x86_64.rpm
- If any conflicts occur during the installation, add the replacefiles parameter to the command and install the client again.
- Run the following command on the FlexusX instance to connect to the FlexusRDS DB instance:
mysql -h <host> -P <port> -u <userName> -p
Example:
mysql -h 192.168.0.1 -P 3306 -u root -p
Table 1 Parameter description Parameter
Description
<host>
The DB instance to be connected. You can connect to your DB instance over a private network or public network. For higher security, private network connection is recommended.
- Private network connection (recommended): Click the DB instance name and obtain the private domain name on the Overview page.
- Public network connection: Click the DB instance name and obtain the EIP on the Overview page. For details about how to bind an EIP to a DB instance, see Binding an EIP to a FlexusRDS Instance or Unbinding an EIP from a FlexusRDS Instance.
Figure 1 Network information
To connect to your DB instance through an EIP, add the EIP and port 3306 to an inbound rule of security group sg-default-smb. For details, see Adding a Security Group Rule.
