Creating a User Account

Run the following commands on the node where the corresponding component is installed to create a user account:

Ubuntu OS

useradd -d /home/hwMindX -u 9000 -m -s /usr/sbin/nologin hwMindX
usermod -a -G HwHiAiUser hwMindX

CentOS OS

useradd -d /home/hwMindX -u 9000 -m -s /sbin/nologin hwMindX
usermod -a -G HwHiAiUser hwMindX

For other OSs:
- For OSs developed based on Ubuntu, see Ubuntu OS.
- For OSs developed based on CentOS, see CentOS OS.
HwHiAiUser is the software running user required by the driver or CANN package.
Run the getent passwd command to check whether the UIDs and GIDs of HwHiAiUser on all physical machines (storage nodes, management nodes, and compute nodes) and containers are the same and are 1000. If the UIDs and GIDs are occupied, services may be unavailable, see User UID or GID Is Occupied.
