Install OAT

Last Updated：2024-03-22 09:34:35 Updated

You can deploy OceanBase Cloud Platform (OCP) on the GUI of OceanBase Admin Toolkit (OAT), a tool used to automatically deploy products in the OceanBase ecosystem. Before you deploy OCP, install OAT first.

For more information, see Install OAT.

Prerequisites

Before you deploy OAT, make sure that:

Your operating system meets conditions listed in the following table.

Architecture	Operating system	Supported version
x86_64	Red Hat Enterprise Linux (RHEL)	7.2 and later
x86_64	CentOS	7.2 and later
x86_64	AliOS	7.2 and later
x86_64	openSUSE	12 SP3 and later
ARM AArch64	AliOS	7.2 and later
ARM AArch64	NeoKylin	7.6
ARM AArch64	Huawei EulerOS	2.0 SP8

You have installed and started Docker. Docker Community Edition 17.03 or later is recommended.
The default port 7000 for OAT is not occupied.

Procedure

Download the installation package of OAT.

For more information, see Prepare installation media.
Run the scp command to upload the OAT installation package to the server.

In the following command, oat_server indicates the IP address of the server where OAT is to be deployed.
```
scp <oat_directory> <oat_server_user>@:<oat_server_ip>
```
Mount the OAT directory.

Create a directory named /data_dir on the server to save persistent data of OAT.

After the /data_dir directory is mounted to the OAT container, OAT will automatically create the /data_dir/logs, /data_dir/images, and /data_dir/db directories respectively for storing OAT system logs, component and product Docker images in OAT, as well as database files of OAT.
```
mkdir -p /data_dir
```
Load the OAT installation package as an image.
```
docker load -i oat.tar
```
Run the docker images command to obtain the tag of the OAT image.

Note

If only one OAT installation package is loaded, just run the following command. If multiple installation packages are loaded, run the docker images command to view the loaded images and then concatenate the first two columns with a colon ( : ) in the command output.

oat_image=`docker images | grep oat | awk '{printf $1":"$2"\n"}'`

Run the docker run command to start OAT.

docker run -d -v /data_dir:/data -p 7000:7000 --restart on-failure:5 $oat_image

After OAT is started, enter http://<<oat_server_ip>:7000 in the address bar of the browser.

If the logon page appears, OAT is successfully installed and started.

Note

The default logon username and password of OAT are admin and aaAA11__. You must change the password upon initial logon.
