Install OAT

This topic describes how to deploy OAT using Docker.

Prerequisites

Before you deploy OAT, confirm the following information:

• Your operating system meets the following requirements:

  Server type	Operating system	Supported version
  x86_64/ARM aarch64	RHEL (and compatible RockyLinux, CentOS, etc.)	7.2 and later
  x86_64/ARM aarch64	Anolis (and compatible Alibaba Cloud Linux, Kylin V10, Unity Operating System (UOS), China Mobile BC-Linux, NeoKylin OS, Zhongke Fangde OS, etc.)	8.4 and later
  x86_64/ARM aarch64	Debian (and compatible Ubuntu, etc.)	11 and later
  x86_64/ARM aarch64	openSUSE	12 SP3 and later
  x86_64/ARM aarch64	openSUSE	12 SP3 and later
  x86_64/ARM aarch64	NeoKylin OS	V6.0.99 and later

• If you use an OAT image package for installation, you must have already installed and started Docker. Docker Community Edition 18.09.9 or later is recommended.

  Notice

  If you deploy OAT using the oat-all-in-one installation package, the install.sh script in oat-all-in-one will automatically install Docker. You do not need to install Docker separately.

• The default OAT port 7000 is not occupied.

Install OAT using the oat-all-in-one installation package

To install OAT, perform the following steps:

1. Contact technical support to obtain the oat-all-in-one installation package for OAT.

2. Extract the oat-all-in-one installation package.

   Example:

   tar -xf oat-all-in-one-arm-xxx.tar
   

3. Run the installation script install.sh.

   Example:

   sh oat-all-in-one-arm/install.sh
   

   Running this command automatically installs Docker (if it is not already present in your environment), deploys OAT, and scans the images and tool software packages included in oat-all-in-one.

4. As prompted, confirm the following information:

   1. Enter the root directory of Docker (it is recommended to set it as a separately mounted directory). The default value is /docker. You can customize this. If Docker is already installed, this step is skipped.
   2. Enter the path for the OAT data directory. The default value is /oat_data. You can customize this.
   3. Enter the OAT HTTP listening port. The default value is 7000. You can customize this.
   4. Enter the OAT database port. The default value is 3306. You can customize this.
   5. Enter the password for the OAT administrator account (set an initial login password). You can customize this.
   6. Access OAT using the returned URL to verify the availability of the OAT service.

   Example:

   Note

   Docker is already installed on the server, so the Docker installation step is skipped this time.

   1. Change the OAT data directory path to /data/oat_data and press Enter.

      Input the OAT data dir: /data/oat_data
      

   2. Use the default value for the OAT HTTP listening port and press Enter directly.

      Input the OAT HTTP listen port: 7000
      

   3. Use the default value for the OAT database port and press Enter directly.

      Input the OAT database port: 3306
      

   4. After modifying the password for the OAT administrator admin user (initial login password), press Enter.

      Input the OAT admin user password(login password): ******
      

   5. Access OAT using the returned URL to verify the availability of the OAT service.

      The return result is as follows:

      Start prepare docker
      Docker is already exists, start check...
      Already installed docker check healthy, skip install docker
      Start prepare OAT

Install OAT using the OAT Docker image

1. Obtain the OAT installation package.

   Notice

   Contact OAT technical support to obtain the installation package.

2. Use the scp command to upload the OAT installation package to the server.

   Here, oat_server is the IP address of the server where OAT is to be deployed.

   scp oat.tgz <oat_server_user>@<oat_server_ip>:~/
   

   Example:

   scp oat_x.x.x_20241025_arm.tgz root@xxx.xxx.xxx.xxx:/home/admin/oat_rpm
   

3. Mount the OAT directory.

   Create a /data_dir directory on the server (the path can be customized; this example uses /data_dir) to store persistent data for OAT.

   After the /data_dir directory is mounted to the OAT container, OAT automatically creates the /data_dir/logs, /data_dir/images, and /data_dir/db directories to store OAT system logs, Docker images for components and products, and OAT database files, respectively.

   mkdir -p /data_dir
   

4. Load the OAT installation package as a Docker image.

   docker load -i oat_xxx_xxxxxxxx_xxx.tgz
   

   Here, oat_xxx_xxxxxxxx_xxx.tgz is the name of the installation package.

   Example:

   docker load -i oat_x.x.x_20241025_arm.tgz
   

   The return result is as follows:

   Loaded image: xxx/oceanbase/oat:x.x.x_20241025_arm
   

5. Run the docker images command to obtain the tag of the OAT image.

   Note

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

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

6. Run the docker run command to start OAT.

   Here, $oat_image is the tag of the OAT image.

   docker run -d --net host --name oat  -v /data_dir:/data -e OAT_INITIAL_ADMIN_PASSWORD=xxx --restart on-failure:5 $oat_image
   

   Note

   • The HTTP service of OAT listens on port 7000 by default. You can specify the -e HTTP_PORT=7001 parameter to change it to another port.
   • You can specify the -e OAT_INITIAL_ADMIN_PASSWORD=xxx parameter to change the password of OAT.
   • OAT uses MariaDB as its data store by default. It listens on port 3306 by default. You can specify the -e DB_PORT=3307 parameter to change it to another port.
   • We recommend that you use the --net host parameter to start OAT, because a container started in bridge network mode may be affected by docker0 bridge failures or the operating system parameter ip_forward.

   Here is an example:

   docker run -d --net host --name oat -v /data_dir:/data -e OAT_INITIAL_ADMIN_PASSWORD=****** --restart on-failure:5 $oat_image
   

   The return result is as follows:

   490344724bfcb2801da271196ebc38b5c15547b796178dc7660553ae62b668c2
   

7. After OAT starts successfully, enter http://<oat_server_ip>:7000 in the browser address bar.

   Replace <oat_server_ip> with the IP address of the server where OAT is deployed.

   If the login page appears in the browser window, OAT has been installed and started successfully.
