Centos minio installation permissions issues

Permissions and solutions for MinIO installation under CentOS system

Permission issues are common problems when deploying MinIO in CentOS environments. This article will introduce several common permission problems and their solutions to help you complete the installation and configuration of MinIO smoothly.

1. Modify the default account and password:

   You can modify the default username and password by setting the environment variables MINIO_ROOT_USER and MINIO_ROOT_PASSWORD . After modification, restarting the MinIO service will take effect.

2. Configure bucket access permissions:

   Setting the bucket to public will cause the directory to be traversed, which poses a security risk. It is recommended to customize the bucket access policy. You can modify the bucket policy through the MinIO management interface, such as setting it to "Custom" and filling in the corresponding JSON configuration to fine-grained control of access permissions.

3. Firewall configuration:

   Make sure the firewall allows the ports used by MinIO (for example, port 9000). You can open the port using the following command:

   sudo firewall-cmd --zone=public --add-port=9000/tcp --permanent
   sudo firewall-cmd --reload

4. File and directory permissions:

   MinIO's data storage path and log files require correct permission settings. Create data directories and log files and set permissions:

   sudo mkdir -p /data/minio
   sudo touch /var/log/minio.log
   sudo chown -R minio:minio /data/mino
   sudo chmod -R 777 /data/minio # Note: 777 is not recommended in the production environment. Strict permissions should be set according to actual needs sudo chown -R minio:minio /var/log/minio.log

   Important tip: In the production environment, chmod -R 777 /data/minio is too loose and poses a security risk. It is recommended to set stricter permissions based on security policies, such as chmod -R 755 /data/minio .

5. Use sudo to escalate permissions:

   If the permissions are insufficient when installing or starting MinIO, you can use sudo command to temporarily elevate the permissions:

   sudo ./minio server /data

6. Create and configure the startup script:

   Create a startup script and set execution permissions to enable the MinIO service to start automatically with the system startup.

   sudo vim /etc/init.d/minio

   Add MinIO startup command to the script and give execution permissions:

   sudo chmod x /etc/init.d/minio
   sudo systemctl enable minio # Use systemctl to manage services (recommended)
   sudo systemctl start minio

   It is recommended to use systemctl management services instead of service because it is more modern and more powerful.

Through the above steps, you can effectively solve the permissions problem during the MinIO installation process in CentOS system. Be sure to double-check all path and file permission settings and use the correct commands to manage permissions and start the service. Pay special attention to the security of permission settings in the production environment to avoid security vulnerabilities caused by excessively loose permissions.
