# enable-nodes-autostart

## Description

For Linux versions that support `systemd`, use `systemd` to restart all nodes on the specified hosts on startup.

To run `systemctl`, the user must have `sudo` privileges on the specified hosts. 

To run `memsqlctl`, the user must have `sudo` privileges on the specified hosts. The `sudo` privileges can be revoked after running the command.

This command may require additional steps for systems running SE Linux in `enforcing` mode.
