Provisioning on-premises nodes

How to meet the software prerequisites with fully manual provisioning

This page documents the preview version (v2.23). Preview includes features under active development and is for development and testing only. For production, use the stable version (v2024.1). To learn more, see Versioning.

v2.20 and earlier

For instructions on preparing nodes for on-premises configurations in v2.20 and earlier, see Create on-premises provider configuration.

In this mode, you manually install each prerequisite software component. Use this mode if you disallow SSH login to a root-privileged user at setup time and instead have a local sudo-privileged user with CLI access to the VM.

Your responsibility now (to meet prerequisites) is to provide a VM with the following pre-installed:

Save for later To configure
VM IP addresses On-premises provider

Manually provision a VM

After you have created the VM, use the following instructions to provision the VM for use with an on-premises provider.

For each node VM, perform the following:

After you have provisioned the nodes, you can proceed to Add instances to the on-prem provider.

Root-level systemd or cron

The following instructions use user-level systemd to provide the necessary access to system resources. Versions prior to v2.20 use root-level systemd or cron. If you have previously provisioned nodes for this provider using either root-level systemd or cron, you should use the same steps, as all nodes in a provider need to be provisioned in the same way. For instructions on provisioning using root-level systemd or cron, see the instructions for v2.18.

Verify the python version installed on the node

Verify that Python 3.5-3.8 is installed on the node. v3.6 is recommended.

In case there is more than one Python 3 version installed, ensure that python3 refers to the right one. For example:

sudo alternatives --set python3 /usr/bin/python3.6
sudo alternatives --display python3
python3 -V

If you are using Python later than v3.6, install the selinux package corresponding to your version of python. For example, using pip, you can install as follows:

python3 -m pip install selinux

Refer to Ansible playbook fails with libselinux-python aren't installed on RHEL8 for more information.

If you are using Python later than v3.7, set the Max Python Version (exclusive) Global Configuration option to the python version. Refer to Manage runtime configuration settings. Note that only a Super Admin user can modify Global configuration settings.

Set up time synchronization

A local Network Time Protocol (NTP) server or equivalent must be available.

Ensure an NTP-compatible time service client is installed in the node OS (chrony is installed by default in the standard AlmaLinux 8 instance used in this example). Then, configure the time service client to use the available time server. The procedure includes this step and assumes chrony is the installed client.

Open incoming TCP/IP ports

Database servers need incoming TCP/IP access enabled for communications between themselves and YugabyteDB Anywhere.

Refer to Networking.

Pre-provision nodes manually

This process carries out all provisioning tasks on the database nodes which require elevated privileges. After the database nodes have been prepared in this way, the universe creation process from YugabyteDB Anywhere will connect with the nodes only via the yugabyte user, and not require any elevation of privileges to deploy and operate the YugabyteDB universe.

Physical nodes (or cloud instances) are installed with a standard AlmaLinux 8 server image. The following steps are to be performed on each physical node, prior to universe creation:

  1. Log in to each database node as a user with sudo enabled (for example, the ec2-user user in AWS).

  2. Add the following line to the /etc/chrony.conf file:

    server <your-time-server-IP-address> prefer iburst
    

    Then run the following command:

    sudo chronyc makestep   # (force instant sync to NTP server)
    
  3. Add a new yugabyte:yugabyte user and group with the default login shell /bin/bash that you set via the -s flag, as follows:

    sudo useradd -u <yugabyte_user_uid> -s /bin/bash --create-home --home-dir <yugabyte_home> yugabyte  # (add user yugabyte and create its home directory as specified in <yugabyte_home>)
    sudo passwd yugabyte   # (add a password to the yugabyte user)
    sudo su - yugabyte   # (change to yugabyte user for execution of next steps)
    
    • yugabyte_user_uid is a common UID for the yugabyte user across all nodes. Use the same UID for the yugabyte user on all nodes in the same cluster. If you don't use a common UID, you may run into issues, for example, if you are using NFS for backups.

    • yugabyte_home is the path to the Yugabyte home directory. By default, this is /home/yugabyte. If you set a custom path for the yugabyte user's home in the YugabyteDB Anywhere UI, you must use the same path here. Otherwise, you can omit the --home-dir flag.

    Ensure that the yugabyte user has permissions to SSH into the YugabyteDB nodes (as defined in /etc/ssh/sshd_config).

    If you are using a RHEL CIS hardened image and want SSH access to database nodes, you need to manually add the yugabyte user to sshd_config.

    sudo sed -i '/^AllowUsers / s/$/ yugabyte/' /etc/ssh/sshd_config
    sudo systemctl restart sshd
    
  4. If the node is running SELinux and the home directory is not the default, set the correct SELinux ssh context, as follows:

    chcon -R -t ssh_home_t <yugabyte_home>
    

    The rest of this document assumes a home of /home/yugabyte. If you set a custom path for home, change the path in the examples as appropriate.

  5. Copy the SSH public key to each DB node. This public key should correspond to the private key entered into the YugabyteDB Anywhere provider.

  6. Run the following commands as the yugabyte user, after copying the SSH public key file to the user home directory:

    cd ~yugabyte
    mkdir .ssh
    chmod 700 .ssh
    cat <pubkey_file> >> .ssh/authorized_keys
    chmod 400 .ssh/authorized_keys
    exit   # (exit from the yugabyte user back to previous user)
    
  7. Add the following lines to the /etc/security/limits.conf file (sudo is required):

    *                -       core            unlimited
    *                -       data            unlimited
    *                -       fsize           unlimited
    *                -       sigpending      119934
    *                -       memlock         64
    *                -       rss             unlimited
    *                -       nofile          1048576
    *                -       msgqueue        819200
    *                -       stack           8192
    *                -       cpu             unlimited
    *                -       nproc           12000
    *                -       locks           unlimited
    
  8. Modify the following line in the /etc/security/limits.d/20-nproc.conf file:

    *          soft    nproc     12000
    
  9. Execute the following to tune kernel settings:

    1. Configure the parameter vm.swappiness as follows:

      sudo bash -c 'sysctl vm.swappiness=0 >> /etc/sysctl.conf'
      sudo sysctl kernel.core_pattern=/home/yugabyte/cores/core_%p_%t_%E
      
    2. Configure the parameter vm.max_map_count as follows:

      sudo sysctl -w vm.max_map_count=262144
      sudo bash -c 'sysctl vm.max_map_count=262144 >> /etc/sysctl.conf'
      
    3. Validate the change as follows:

      sysctl vm.max_map_count
      
  10. Perform the following to prepare and mount the data volume (separate partition for database data):

    • List the available storage volumes, as follows:

      lsblk
      
    • Perform the following steps for each available volume (all listed volumes other than the root volume):

      sudo mkdir /data   # (or /data1, /data2 etc)
      sudo mkfs -t xfs /dev/nvme1n1   # (create xfs filesystem over entire volume)
      sudo vi /etc/fstab
      
    • Add the following line to /etc/fstab:

      /dev/nvme1n1   /data   xfs   noatime   0   0
      
    • Exit from vi, and continue, as follows:

      sudo mount -av # (mounts the new volume using the fstab entry, to validate)
      sudo chown yugabyte:yugabyte /data
      sudo chmod 755 /data
      

Custom tmp directory for CIS hardened RHEL 8 or 9

For CIS hardened RHEL 8 or 9, if you use the default /tmp directory, prechecks fail when deploying universes with an access denied error.

To resolve this, create a custom tmp directory called /new_tmp on the database nodes:

sudo mkdir -p /new_tmp; sudo chown yugabyte:yugabyte -R /new_tmp

In addition, after you create the on-premises provider, set the provider runtime configuration flag yb.filepaths.remoteTmpDirectory to /new_tmp.

Finally, when creating universes using the provider, set YB-Master and YB-TServer configuration flag tmp_dir to the custom /new_tmp directory.

Install Prometheus Node Exporter

Download the Prometheus Node Exporter, as follows:

wget https://github.com/prometheus/node_exporter/releases/download/v1.7.0/node_exporter-1.7.0.linux-amd64.tar.gz

If you are doing an airgapped installation, download the Node Exporter using a computer connected to the internet and copy it over to the database nodes.

On each node, perform the following as a user with sudo access:

  1. Copy the node_exporter-1.7.0.linux-amd64.tar.gz package file that you downloaded into the /tmp directory on each of the YugabyteDB nodes. Ensure that this file is readable by the user (for example, ec2-user).

  2. Run the following commands:

    sudo mkdir /opt/prometheus
    sudo mkdir /etc/prometheus
    sudo mkdir /var/log/prometheus
    sudo mkdir /var/run/prometheus
    sudo mkdir -p /tmp/yugabyte/metrics
    sudo mv /tmp/node_exporter-1.7.0.linux-amd64.tar.gz  /opt/prometheus
    sudo adduser --shell /bin/bash prometheus # (also adds group "prometheus")
    sudo chown -R prometheus:prometheus /opt/prometheus
    sudo chown -R prometheus:prometheus /etc/prometheus
    sudo chown -R prometheus:prometheus /var/log/prometheus
    sudo chown -R prometheus:prometheus /var/run/prometheus
    sudo chown -R yugabyte:yugabyte /tmp/yugabyte/metrics
    sudo chmod -R 755 /tmp/yugabyte/metrics
    sudo chmod +r /opt/prometheus/node_exporter-1.7.0.linux-amd64.tar.gz
    sudo su - prometheus (user session is now as user "prometheus")
    
  3. Run the following commands as user prometheus:

    cd /opt/prometheus
    tar zxf node_exporter-1.7.0.linux-amd64.tar.gz
    exit   # (exit from prometheus user back to previous user)
    
  4. Edit the following file:

    sudo vi /etc/systemd/system/node_exporter.service
    

    Add the following to the /etc/systemd/system/node_exporter.service file:

    [Unit]
    Description=node_exporter - Exporter for machine metrics.
    Documentation=https://github.com/William-Yeh/ansible-prometheus
    After=network.target

    ExecStart=/opt/prometheus/node_exporter-1.7.0.linux-amd64/node_exporter  --web.listen-address=:9300 --collector.textfile.directory=/tmp/yugabyte/metrics
    
  5. Exit from vi, and continue, as follows:

    sudo systemctl daemon-reload
    sudo systemctl enable node_exporter
    sudo systemctl start node_exporter
    
  6. Check the status of the node_exporter service with the following command:

    sudo systemctl status node_exporter
    

Enable yugabyte user processes to run after logout

To enable services to run even when the yugabyte user is not logged in, run the following command as the yugabyte user:

loginctl enable-linger yugabyte

Then add the following to /home/yugabyte/.bashrc:

export XDG_RUNTIME_DIR=/run/user/$(id -u yugabyte)

You can install systemd-specific database service unit files, as follows:

  1. Create the directory .config/systemd/user in the yugabyte home directory. For example:

    mkdir /home/yugabyte/.config/systemd/user
    
  2. Add the following service and timer files to the /.config/systemd/user directory you created:

Ulimits on Red Hat Enterprise Linux 8

On Red Hat Enterprise Linux 8-based systems (Red Hat Enterprise Linux 8, Oracle Enterprise Linux 8.x, Amazon Linux 2), additionally, add the following line to /etc/systemd/system.conf and /etc/systemd/user.conf:

DefaultLimitNOFILE=1048576

You must reboot the system for these two settings to take effect.

Install node agent

The YugabyteDB Anywhere node agent is used to manage communication between YugabyteDB Anywhere and the node. When node agent is installed, YugabyteDB Anywhere no longer requires SSH or sudo access to nodes. For more information, refer to Node agent FAQ.

For automated and assisted manual provisioning, node agents are installed onto instances automatically when adding instances, or when running the pre-provisioning script using the --install_node_agent flag.

Use the following procedure to install node agent for fully manual provisioning.

To install the node agent manually, as the yugabyte user, do the following:

  1. If you are re-provisioning the node (for example, you are patching the Linux operating system, where node agent has previously been installed on the node), you need to unregister the node agent before installing node agent.

  2. Download the installer using the YugabyteDB Anywhere API token of the Super Admin. Run the following command from your YugabyteDB nodes:

    curl https://<yugabytedb_anywhere_address>/api/v1/node_agents/download --fail --header 'X-AUTH-YW-API-TOKEN: <api_token>' > installer.sh && chmod +x installer.sh
    

    To create an API token, navigate to your User Profile and click Generate Key.

  3. Run the following command to download the node agent's .tgz file which installs and starts the interactive configuration:

    ./installer.sh -c install -u https://<yba_address> -t <api_token>
    

    For example, if you run the following:

    # To ignore verification of YBA certificate, add --skip_verify_cert.
    ./installer.sh  -c install -u https://10.98.0.42 -t 301fc382-cf06-4a1b-b5ef-0c8c45273aef
    

    You should get output similar to the following:

    * Starting YB Node Agent install
    * Creating Node Agent Directory
    * Changing directory to node agent
    * Creating Sub Directories
    * Downloading YB Node Agent build package

            • Completed Node Agent Configuration
            • Node Agent Registration Successful
    You can install a systemd service on linux machines by running sudo node-agent-installer.sh -c install_service --user yugabyte (Requires sudo access).
    
  4. Run the install_service command as a sudo user:

    sudo node-agent-installer.sh -c install_service --user yugabyte
    

    This installs node agent as a systemd service. This is required so that the node agent can perform self-upgrade, database installation and configuration, and other functions.

When the installation has been completed, the configurations are saved in the config.yml file located in the node-agent/config/ directory. You should refrain from manually changing values in this file.

Preflight check

After the node agent is installed, configured, and connected to YugabyteDB Anywhere, you can perform a series of preflight checks without sudo privileges by using the following command:

node-agent node preflight-check

The result of the check is forwarded to YugabyteDB Anywhere for validation. The validated information is posted in a tabular form on the terminal. If there is a failure against a required check, you can apply a fix and then rerun the preflight check.

Expect an output similar to the following:

Result

If the preflight check is successful, you add the node to the provider (if required) by executing the following:

node-agent node preflight-check --add_node

Reconfigure a node agent

If you want to use a node that has already been provisioned in a different provider, you can reconfigure the node agent.

To reconfigure a node for use in a different provider, do the following:

  1. Remove the node instance from the provider using the following command:

    node-agent node delete-instance
    
  2. Run the configure command to start the interactive configuration. This also registers the node agent with YBA.

    node-agent node configure -t <api_token> -u https://<yba_address>
    

    For example, if you run the following:

    node-agent node configure -t 1ba391bc-b522-4c18-813e-71a0e76b060a -u https://10.98.0.42

    • Completed Node Agent Configuration
    • Node Agent Registration Successful
    

If you are running v2.18.5 or earlier, the node must be unregistered first. Use the following procedure:

  1. If the node instance has been added to a provider, remove the node instance from the provider.

  2. Unregister node agent.

  3. Stop the systemd service as a sudo user.

    sudo systemctl stop yb-node-agent
    
  4. Run the configure command to start the interactive configuration. This also registers the node agent with YBA.

    node-agent node configure -t <api_token> -u https://<yba_address>
    
  5. Start the Systemd service as a sudo user.

    sudo systemctl start yb-node-agent
    
  6. Verify that the service is up.

    sudo systemctl status yb-node-agent
    
  7. Run preflight checks and add the node as yugabyte user.

    node-agent node preflight-check --add_node
    

Unregister node agent

When performing some tasks, you may need to unregister the node agent from a node.

To unregister node agent, run the following command:

node-agent node unregister

After running this command, YBA no longer recognizes the node agent.

If the node agent configuration is corrupted, the command may fail. In this case, unregister the node agent using the API as follows:

  • Obtain the node agent ID:

    curl -k --header 'X-AUTH-YW-API-TOKEN:<api_token>' https://<yba_address>/api/v1/customers/<customer_id>/node_agents?nodeIp=<node_agent_ip>
    

    You should see output similar to the following:

    [{
        "uuid":"ec7654b1-cf5c-4a3b-aee3-b5e240313ed2",

    }]
    
  • Use the value of the field uuid as <node_agent_id> in the following command:

    curl -k -X DELETE --header 'X-AUTH-YW-API-TOKEN:<api_token>' https://<yba_address>/api/v1/customers/<customer_id>/node_agents/<node_agent_id>
