Step 1: Create a BMS¶
Scenarios¶
This section helps you quickly create a BMS that will be used as a web server. For details about all the parameters used for creating a BMS, see Region and AZ. To create a BMS by calling an API, see "Creating a BMS (Native OpenStack API)" in Bare Metal Server API Reference.
Procedure¶
Log in to the Cloud Server Console.
In the navigation pane, choose Bare Metal Server.
In the upper right corner, click Allocate BMS.
Configure parameters.
Specify Region and AZ.
Note
After the BMS is created, you cannot change its region or AZ.
Set Flavor.
Available flavors vary depending on the region and AZ you select. Web servers are mainly used for web page access and do not require strong computing capabilities. In addition, only a small amount of storage is required for recording logs. Therefore, select physical.h2.large.
Set Image.
Select Public image and then CentOS 7.4 64bit for BareMetal.
Set License Type.
Select Use system license. You will be billed for the license. If you have an OS license of your own, select Bring your own license (BYOL).
Specify Disk.
An EVS disk can be attached to a BMS. However, whether an EVS disk can be attached is determined by the flavor and image you select.
Set VPC and NIC.
Retain the default values. When you use cloud services for the first time, the system automatically creates a VPC default-vpc and a subnet default-subnet for you. You can also create VPCs and subnets.
Note
The system creates a security group for you by default. The default security group rule allows all outgoing data packets and blocks incoming data packets. In this way, the default security group rule ensures the security of basic BMS communications.
Set EIP.
BMSs without an EIP cannot be connected to the Internet and are only used for deploying services in a private network or used in a cluster. Select Automatically assign and set Bandwidth.
Set Login Mode.
Select the key pair created in Making Preparations from the drop-down list and select I acknowledge that I have obtained private key file xxx.pem and that without this file I will not be able to log in to my BMS.
Configure Advanced Settings.
Select Do not configure.
Set BMS Name.
The BMS name is in the format bms-four random digits. To easily identify it, you can add the function to its name, for example, bms-7676-nginx.
Set Quantity.
Set the value to 1.
Click Allocate Now. Confirm the specifications and click Submit.
Result¶
The BMS creation process requires about 5 to 30 minutes to complete. Refresh the BMS list. After the BMS status changes from Creating to Running, the BMS is created successfully.
Follow-up Operations¶
A BMS that functions as a web server must allow ICMP traffic on ports 80 and 443. These rules are not configured for the default security group. You need to add the rules after you create the BMS. For details, see Virtual Private Cloud User Guide.
Protocol | Direction | Port Range | Source |
|---|---|---|---|
TCP | Inbound | 80 | 0.0.0.0/0 |
TCP | Inbound | 443 | 0.0.0.0/0 |
ICMP | Inbound | All | 0.0.0.0/0 |
