Some network administrators may use this service more frequently, because the samba service allows us to share a directory on the linux machine, and then let the windows machine access it; it is as convenient as file sharing between windows and windows; it can also configure some user login rights.

Server side

# # installation

[root@wy ~] # yum install-y samba samba-client

Explanation:

Samba server

Samba-client client

# # viewing configuration files

[root@wy ~] # vim / etc/samba/smb.conf

Explanation:

[global] Global Settin

Workgroup = MYGROUP working group

Server string = Samba Server Version% v displayed information (custom)

Security = user security level

User: need to be verified by user name and password before you can log in to our samba shared file

Shell: if anonymous users, do not need users, do not need authentication to directly access shared files, the most insecure

Server: checking accounts and passwords, that is, authentication is done by another server, which is done by a remote console

Domain: this involves the domain controller in windows, which can verify the user's account and password through the domain controller.

Passdb backend = how the user name and password are stored in tdbsam. Default is tdbsam, and the other two are smbpasswd and ldapsam

Smbpasswd is a user who uses a tool smbpasswd to go to the operating system, mapping the user of the system into a virtual user.

Then we set a password for samba.

Tdbsam is similar to smbpasswd, but there are differences (such as the way passwords are stored); tdbsam is more secure

Ldapsam authenticates users based on ldap account management, and needs the help of our ldap service

Load printers = yes cups options = raw these two are about printer settings

[homes] this module is about whether your user's home directory can be shared.

[printers] this module is related to the printer

Do an experiment, the requirement: share a directory out, anyone can access the directory, do not need to enter a user name and password to access, just like ftp anonymous login, but the requirement is read-only, can not write

# # Editing configuration File

[root@wy ~] # vim / etc/samba/smb.conf

Security = share

Workgroup = WORKGROUP / / because windows is workgroup

* add at the end of the file

[wyy]

Comment = share all / / Custom description

Path = / tmp/sambadir / / shared directory

Browseable = yes / / whether it is allowed in our working group

Public = whether yes / / is public or not

Writable = no / / not writable

# # start the service

[root@wy ~] # / etc/init.d/smb start

Start the SMB service: [OK]

# # create a shared directory first

[root@wy ~] # mkdir / tmp/sambadir

[root@wy ~] # cp / etc/passwd / tmp/sambadir/1.txt

# # create a directory under a shared directory to verify whether it is not writable (non-writable is configured in the configuration file)

[root@wy ~] # mkdir / tmp/sambadir/test

[root@wy ~] # chmod 777! $

Chmod 777 / tmp/sambadir/test

Access under windows

# # opening the Operation of windows

# # verify that it is not writable

# # creating a Test account

[root@wy ~] # useradd smbuser1

Explanation:

Its password does not need to be defined, because we do not log in to the samba service with the system user name and password, but it is important to understand that this samba service logs in with the same user name as the system user name, but in fact, our smbuser1 is only a mapping, it is only a mapping of the system user.
