Construction of Samba File Sharing server in centos Linux

Preface

When we use Windows as the client, we usually need to share files and print files. As one of Windows network functions, these requirements can usually be achieved between Windows clients through the features inherent in Windows network. However, with Samba, we can also enable a centos host to be compatible with the Windows Network and achieve the same functionality, so as to make full use of the availability of the centos host.

This document describes how to share files in a Windows Network by building a Samba server.

Install samba

First, install Samba online through yum.

[Root @ sample ~] # Yum-y install Samba plugin install samba

Configure samba

Then, configure Samba as needed by editing/etc/samba/smb. conf. Here, the principle of this article is to only apply file sharing to the Intranet and give the directory to be shared full read/write permissions.
[Root @ sample ~] # Vi/etc/samba/smb. conf configure edit the samba configuration file

#====================================== Global settings ==================== ======================================
[Global] locate this line (Global Setting label) and add the following lines below this line:

DOS charset = gb2312 character sets the Windows client text encoding to simplified Chinese gb2312
UNIX charset = gb2312 bytes indicates that the code for creating a file or directory on the centos server where Samba is located is gb2312.
Display charset = gb2312 character specifies the default text encoding of the page when SWAT (a tool that controls Samba through a browser) is used.
Directory mask = 0777 catalog specifies the attributes of the new directory (the following four rows)
Force directories mode = 0777
Directory Security mask = 0777
Force Directory Security mode = 0777
Create mask = 0777 objects specifies the attributes of the new file (the following four rows)
Force create mode = 0777
Security mask = 0777
Force security mode = 0777

Workgroup = mygroup groups find this row and change the workgroup name to the workgroup name defined in windows.
Bytes
Workgroup = workgroup worker changes to this State. Here, the default "workgroup" of Windows XP is used as an example.

; Hosts allow = 192.168.1. 192.168.2. 127. Empty find this row, remove the ";" at the beginning of the line, and set access restrictions.
Bytes
Hosts allow = 192.168.0. 127. The access status changes to this status. The intranet IP address and local IP address are specified. Only access in these two cases is allowed.

Enter the following lines at the end of the configuration file to define the public shared directory:

[Public]
Comment = Public stuff
Path =/home/samba folder specify the location of the shared directory
Public = Yes
Writable = Yes others attributes that grant write permission to the shared directory

Next, create a dedicated directory that will be shared to the Windows Network through Samba.
[Root @ sample ~] # Mkdir/home/samba plugin create a dedicated directory for shared files

[Root @ sample ~] # Chown-r nobody./home/samba secrets set the private directory to nobody

[Root @ sample ~] # Chmod 777/home/samba connector set the dedicated Directory attribute to 777

Before connecting to the server, you must set the user used to log on to Samba in advance. Here, we use the samba standard Samba user database management tool "smbpasswd" in centos as an example to create user data for logging on to Samba. Note: The premise of using smbpasswd to create a user is that the user exists in the System user-the information of the user in the samba user database can be created based on the System user.

[Root @ sample ~] # Smbpasswd-A centospub plugin adds the System user centospub (example) to the samba user database

New smb password: Login enter the password used by the user to log on to Samba
Retype new smb password: Confirm again to enter the password
Added user centospub.

Start the samba Service

Before starting the samba service, open the port used by Samba in the firewall settings.
[Root @ sample ~] # Vi/etc/sysconfig/iptables configure edit the iptables configuration file

-A RH-Firewall-1-INPUT-M state -- state new-m tcp-p tcp -- dport 25-J accept rows find this row and add the following lines below:
-A RH-Firewall-1-INPUT-M state -- state new-m tcp-p tcp -- dport 139-J accept
-A RH-Firewall-1-INPUT-M state -- state new-m tcp-p tcp -- dport 445-J accept
-A RH-Firewall-1-INPUT-p udp-m udp -- dport 137-J accept
-A RH-Firewall-1-INPUT-p udp-m udp -- dport 138-J accept

[Root @ sample ~] #/Etc/rc. d/init. d/iptables restart iptables to bring the new rule into effect
Flushing firewall rules: [OK]
Setting chains to policy accept: Filter [OK]
Unloading iptables modules: [OK]
Applying iptables firewall rules: [OK]

Finally, start the samba service.
[Root @ sample ~] # Chkconfig SMB on startup

[Root @ sample ~] # Chkconfig -- list SMB restart confirm the samba startup tag and check that 2-5 is in the on status
SMB 0: off 1: off 2: On 3: On 4: On 5: on 6: Off

[Root @ sample ~] #/Etc/rc. d/init. d/SMB start restart start the samba Service
Starting SMB services: [OK]
Starting nmb services: [OK]

Connect to the Samba server from a Windows Client

After the samba service is started on the server end, we can connect to Samba from a Windows client over a Windows network. Windows XP is used as an example to describe the connection process as follows:

1. Open "Network neighbors" from the desktop and click "view workgroup computers;

2. Confirm the connection to the Samba server and double-click the connection. (The host name in this document is sample)

3. Enter the username and password of the samba user pre-set on the server. (The username is the same as the system username. The password must be the samba-specific password set for the System user through smbpasswd .)

4. Then confirm that you can connect to the Samba server and the root directory and the samba dedicated shared directory appear.

Finally, create, modify, and delete files in the corresponding directory to test the operability of the corresponding permissions.
