MinIO fails to start as systemctl service but manual start using command line works

Question

I am trying to setup MinIO cluster (4 VMs) using the guide here https://min.io/docs/minio/linux/operations/install-deploy-manage/deploy-minio-multi-node-multi-drive.html All the VMs are identical in configuration. All the VMs have one drive mounted at /data/minio. OS: Rocky Linux release 8.7 (Green Obsidian). Firewall is open for ports 8080 and 8081. Trying to setup minio without TLS certificate.

1. Installed the MinIO Binary on Each Node
   wget https://dl.min.io/server/minio/release/linux-amd64/archive/minio-20230407052858.0.0.x86_64.rpm -O minio.rpm
sudo dnf install minio.rpm

2. systemd Service File
   I have not edited the service file (/etc/systemd/system/minio.service) that was created by the above RPM installation and left it as such.

3. Create the Service Environment File
   As root, I created this file /etc/default/minio with the following contents

MINIO_VOLUMES="http://minio{1...4}.domain.com:8080/data/minio"
MINIO_OPTS="--address :8080 --console-address :8081"
MINIO_ROOT_USER=minioadmin
MINIO_ROOT_PASSWORD=admin
MINIO_SERVER_URL="http://minio1.domain.com:8080"

4. Tried to start the service
   systemctl start minio.service

Journalctl does not give any error message apart from the following:
minio.service: Main process exited, code=exited, status=1/FAILURE
minio.service: Failed with result 'exit-code'.

Manual start: when i source the above env file and start the server '/usr/local/bin/minio server $MINIO_OPTS $MINIO_VOLUMES', it worked as i can access the minio console and can login.

Without any error messages in the journalctl, i have no clue where to start the troubleshooting. Can anyone see if i am missing something obvious please?

Answer 1

Solved it. For the benefit of others: if the password is not at least 8 characters, then the MinIO service does not start. After changing the password to longer string, the service started as expected.
