How to install and configure samba server in RHEL 7 or redhat linux 7

Login on Samaba server
Check samba rpm installed or not, if not installed please install it,

[root@localhost ~]# rpm -qa | grep samba
[root@localhost ~]# yum install samba*

Create a directory in root file system which is shared with client.

[root@localhost ~]#mkdir -p /home/testuser/test

Add a new group or can use existing group

To provide access on shared directory,Here we are adding new group called samba

[root@localhost ~]#groupadd samba

Change the group and permission of sharing folder

[root@localhost ~]#chgrp -R samba /home/testuser/test
[root@localhost ~]#chmod -R 777 /home/testuser/test

create user, add into group and set samba password

[root@localhost ~]#useradd testuser
[root@localhost ~]#usermod -G samba testuser
[root@localhost ~]#smbpasswd -a testuser

Now Edit /etc/samba/smb.conf file

Note: Please take a backup of origianl file.

[root@localhost ~]#cd /etc/samba/
[root@localhost ~]#cp -p smb.conf smb.conf.orig

And add the below given contents in last line of /etc/samba/smb.conf file.

vi /etc/samba/smb.conf

[test]
comment = shared-directory
path = /home/testuser/test
public = no
valid users = testuser, @samba
writable = yes
browseable = yes
create mask = 0774
directory mask = 4774

##Edit these lines in /etc/samba/smb.conf . To allow network to reach samba server

interfaces = lo ens32 192.168.1.0/24
hosts allow = 127. 192.168.1.

security = user
passdb backend = tdbsam
netbios name = localhost
server string = Samba Server localhost
workgroup = MYGROUP
log file = /var/log/samba/samba.log
max log size = 50
security = server

Add services in /etc/services files

vi /etc/services
 
netbios-ns    137/tcp    # netbios name service
netbios-ns    137/udp    # netbios name service
netbios-dgm    138/tcp    # netbios datagram service
netbios-dgm    138/udp    # netbios datagram service
netbios-ssn    139/tcp    # netbios session service
netbios-ssn    139/udp    # netbios session service

Note: Please check these above ports are open from this samba server to client machine

Now start the smb and nmb services.

systemctl start smb.service
systemctl start nmb.service

Enable smb and nmb service at booting of system

systemctl enable smb.service
systemctl enable nmb.service

Note 1: firewalld service not enable on this server so no need to add any rule.
Note 2: selinux is in permissive state so no need to change the selinux security context.

Now login on window machine

and mount this samba share on the server.

\\localhost.redhat.com\test

Job for smb.service failed because the control process exited with error code. Redhat 7 or RHEL 7

Job for smb.service failed because the control process exited with error code.

I just recently installed the samba server on my Red Hat Linux 7 / RHEL 7 operating system server. After configuration when I have taken restart of samba service, I have got the above error. Due to this samba service not running on my linux machine.

[root@localhost~]# systemctl restart smb.service

I will reveive below error

Job for smb.service failed because the control process exited with error code.
See "systemctl status smb.service" and "journalctl -xe" for details.

So in such case, first I have checked the my samba configuration is ok or not, to do this, please run the below command.

#smbstatus

the above command gives me the below output.

"WARNING: Ignoring invalid value 'share' for parameter 'security'
Can't load /etc/samba/smb.conf - run testparm to debug it"

That's means something wrong in my samba configuration.

So open the /etc/samba/smb.conf file and commented the below line which starts with security.

#security = server

now again run the smbstatus command which gives the new output.

[root@localhost~]# smbstatus

Samba version 4.2.10
PID     Username      Group         Machine            Protocol Version
------------------------------------------------------------------------------

Service      pid     machine       Connected at
-------------------------------------------------------

If you are getting such output that means now your configuration is ok, now please restart the samba service again.

[root@localhost~]# systemctl restart smb.service

[root@localhost~]# systemctl status smb.service
