Getting Started

(Optional) Modifying Security Group Rules

• This solution uses port 22 to remotely log in to the ECS. By default, the VPC subnet created in this solution allows access from port 22. To configure an IP address whitelist, see Modifying a Security Group Rule.

A security group is a collection of access control rules for cloud resources, such as cloud servers, containers, and databases, to control inbound and outbound traffic. Cloud resources associated with the same security group have the same security requirements and are mutually trusted within a VPC.

You can modify the security group policy, for example, by adding, modifying, or deleting a TCP port, as follows:

• Adding a security group rule: Add an inbound rule and enable a TCP port if needed.
• Modifying a security group rule: Inappropriate security group settings can be a serious security risk. You can modify security group rules to ensure the network security of your ECSs.
• Deleting a security group rule: If the source or destination IP address of an inbound or outbound security group rule changes, or a port does not need to be enabled, you can delete the security group rule.

(Optional) Changing the MySQL Database Password

1. Log in to the ECS console, locate the created ECS, and click Remote Login to log in to the Linux ECS.

2. On the Linux ECS, enter the username and password and press Enter.

3. Run the mysql -u root -p command to log in to the MySQL database as user root. Then, press Enter and enter the password. Then run the SET PASSWORD command to change the password: set password for root @localhost= password ('new password').

4. To change the password of the MySQL user database, log in to the MySQL database, enter grant all on wordpress.* to wordpressuser@localhost identified by 'new password';, and press Enter. Then run the exit command to exit the MySQL database.
