How to install Samba server on CentOS 6


Part 1: Configuring anonymous share with samba server
To install the samba package,enter the following command:

sudo yum install samba samba-client samba-common


Check the version of installed samba software by using this command:

smbd --version


Configure the samba service, so that, it will start automatically at boot time:

sudo chkconfig smb on
sudo chkconfig nmb on


Disable the SELinux:

sudo nano /etc/selinux/config


Change SELinux from enforcing to disabled:

SELINUX=disabled


Add these Iptables rules, so that samba will work perfectly:

sudo iptables -I INPUT 4 -m state --state NEW -m udp -p udp --dport 137 -j ACCEPT
sudo iptables -I INPUT 5 -m state --state NEW -m udp -p udp --dport 138 -j ACCEPT
sudo iptables -I INPUT 6 -m state --state NEW -m tcp -p tcp --dport 139 -j ACCEPT
sudo service iptables save


Restart the Server!!!
Go to your Windows machine and use this command in order to check the WORKGROUP name:

net config workstation


It will show the output, something like this:

Backup the smb.conf file, then delete it and create the new one:

sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
sudo rm /etc/samba/smb.conf
sudo touch /etc/samba/smb.conf
sudo nano /etc/samba/smb.conf


Add these lines, in your smb.conf file (or change it according to your requirement):

#======================= Global Settings =====================================
[global]
 workgroup = WORKGROUP
 security = share
 map to guest = bad user
#============================ Share Definitions ==============================
[MyShare]
 path = /samba/share
 browsable =yes
 writable = yes
 guest ok = yes
 read only = no


Save the smb.conf file and restart the service:

sudo service smb restart
sudo service nmb restart


Access the samba share from windows (where centos is the name of my samba server):

wao, we are able to access the samba share successfully :-)

Let’s try to create something, inside the share folder:

Error, we cannot create anything inside the share folder :-(

Check the current permission on the samba share:

cd /samba/
ls -l


Change it, in such a way that everyone can read and write it(Check it, that it is allowed in your environment or not):

sudo chmod -R 0777 share
ls -l


Try to create something again, inside the share folder:

Verify the newly created file on samba server:

cd share/
ls -l


Part 2: Add and manage users and groups
Add a group in your CentOS server (in my case smbgrp):

sudo groupadd smbgrp


Create a new share, set the permission on the share:

cd /samba/
sudo mkdir secure
sudo chown -R arbab:smbgrp secure/
ls -l
sudo chmod -R 0770 secure/
ls -l


Add the user to the samba group and create samba password:

sudo usermod -a -G smbgrp arbab
sudo smbpasswd -a arbab


Edit the smb.conf file:

sudo nano /etc/samba/smb.conf


Add the newly created samba share in smb.conf file:

[Secure]
path = /samba/secure
 valid users = @smbgrp
 guest ok = no
 writable = yes
 browsable = yes


Restart the samba service:

sudo service smb restart
sudo service nmb restart


Check the syntax error with testparm:

sudo testparm


Testing from Windows Machine:


Verification from CentOS server:

cd /samba/secure/
ls -l


Hope this will help you!
