![]() This directory will be accessible by all authenticated users. To user sadmin and group sambashare: sudo chown sadmin:sambashare /samba/users Next, create the Users share directory: sudo mkdir /samba/users Set a password and enable the user: sudo smbpasswd -a sadmin sudo smbpasswd -e sadmin The command above will also create a group sadmin and add the user to both sadmin and sambashare groups. Later if you want to grant administrative permissions to another user simply add that user to the sadmin groupĬreate the administrative user by typing: sudo useradd -M -d /samba/users -s /usr/sbin/nologin -G sambashare sadmin All members of this group will have administrative permissions. Next, let’s create a user and group sadmin. To create another user repeat the same process as when creating the user josh. Once the password is set, enable the Samba account by typing: sudo smbpasswd -e josh Enabled user josh. You will be prompted to enter and confirm the user password. sudo chmod 2770 /samba/joshĪdd the josh user account to the Samba database by setting the user password: sudo smbpasswd -a josh To 2770 and the sadmin user creates a new file the user josh will not be able to read/write to this file. For example, if you don’t set the directory’s permissions This way, no matter which user creates a new file, the file will have group-owner of sambashare. The following command will add the setgid bit to the /samba/josh directory so the newly created files in this directory will inherit the group of the parent directory. -G sambashare - add the user to the sambashare group.Īnd set the directory ownership to user josh and group sambashare: sudo mkdir /samba/josh sudo chown josh:sambashare /samba/josh.-s /usr/sbin/nologin - disable shell access for this user.-d /samba/josh - set the user’s home directory to /samba/josh.-M -do not create the user’s home directory.The useradd options have the following meanings: To create a new user named josh, use the following command: sudo useradd -M -d /samba/josh -s /usr/sbin/nologin -G sambashare josh ![]() That will have access to its private file share and one administrative account with read and write access to all shares on the Samba server. ![]() We will create the users using the standard Linux useradd tool and then set the user password with the smbpasswd utility.Īs we mentioned in the introduction, we’ll create a regular user Samba uses Linux users and group permission system but it has its own authentication mechanism separate from the standard Linux authentication. To sambashare: sudo chgrp sambashare /samba ![]() Later we will add all Samba users to this group. Start by creating the /samba directory: sudo mkdir /samba To do so, run the following commands: firewall-cmd -permanent -zone=public -add-service=samba firewall-cmd -zone=public -add-service=samba Creating Samba Users and Directory Structure #įor easier maintainability and flexibility instead of using the standard home directories ( /home/user) all Samba directories and data will be located in the /samba directory. Now that Samba is installed and running on your CentOS machine, you’ll need to configure your firewallĪnd open the necessary ports. The nmbd service provides NetBIOS over IP naming services to clients and listens on UDP port 137. The smbd service provides file sharing and printing services and listens on TCP ports 139 and 445. Once the installation is completed, start the Samba services and enable them to start automatically on system boot: sudo systemctl start smb.service sudo systemctl start nmb.service sudo systemctl enable smb.service sudo systemctl enable nmb.service To install it on your CentOS system run the following command: sudo yum install samba samba-client Samba is available from the standard CentOS repositories. Prerequisites #īefore you begin, make sure you are logged in to your CentOS 7 system as a user with sudo privileges Later in the tutorial, we will also provide detailed instructions on how to connect to the Samba server from Linux, Windows and macOS clients. The file shares will be accessible from all devices on your network. josh - This share will be accessible with read/write permissions only by users josh and sadmin.users - This share will be accessible with read/write permissions by all users.josh - A regular user with its own private file share.sadmin - An administrative user with read and write access to all shares.We’ll create the following Samba shares and users. In this tutorial, we will show how to install Samba on CentOS 7 and configure it as a standalone server to provide file sharing across different operating systems over a network. Samba is a free and open-source re-implementation of the SMB/CIFS network file sharing protocolĪllows end users to access files, printers, and other shared resources.
