Deploying MinIO

Perform the following operations on all the four nodes.

Create an installation directory.

mkdir -p /opt/minio/{run,data} && mkdir -p /etc/minio

Download the MinIO installation package to /opt/minio/run.

cd /opt/minio/run
wget https://dl.min.io/server/minio/release/linux-arm64/archive/minio.RELEASE.2020-12-12T08-39-07Z

Configure the startup file.
```
vim /opt/minio/run/run.sh
```
Add the following content to the script:
```
#!/bin/bash
export MINIO_ACCESS_KEY=admin
export MINIO_SECRET_KEY=hpc8912011
/opt/minio/run/minio.RELEASE.2020-12-12T08-39-07Z server --config-dir /etc/minio \
http://192.168.122.2/opt/minio/data \
http://192.168.122.3/opt/minio/data \
http://192.168.122.4/opt/minio/data \
http://192.168.122.5/opt/minio/data
```
- The default MinIO port is 9000.
- MINIO_ACCESS_KEY: user name, which contains at least five characters.
- MINIO_SECRET_KEY: password, which contains at least eight characters. A simple password will cause MinIO startup failure.
- –config-dir: specifies the directory for storing cluster configuration files.
- Set the IP address based on the site requirements.

Create a minio.server file.

vim /usr/lib/systemd/system/minio.service

Add the following content to the script:

[Unit]
Description=Minio service
Documentation=https://docs.minio.io/

[Service]
WorkingDirectory=/opt/minio/run/
ExecStart=/opt/minio/run/run.sh

Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

Modify the permission.

chmod +x /usr/lib/systemd/system/minio.service && chmod +x /opt/minio/run/minio.RELEASE.2020-12-12T08-39-07Z && chmod +x /opt/minio/run/run.sh

Start the MinIO cluster.

systemctl daemon-reload
systemctl start minio
systemctl enable minio

Check the cluster status.
```
systemctl status minio.service
```
If active (running) is displayed, the startup is successful.
