Install and configure the Samba server in CentOS 7

Notes on the installation and configuration process of the Samba server in CentOS 7.

Suppose we have such a scenario

Share Name	Path	Permission
SHAREDOC	/Smb/docs	All personnel, including guests, can access
RDDOCS	/Smb/tech	Allow read/write access only to users in a specific group

The group name is RD. Currently, Alice, Jack, and Tom are three people.

Summary:
Server and Client software to interoperate with Windows machines
Description:
Samba is the standard Windows interoperability
Suite of programs for Linux and Unix.
Tips: Also the previous major change in SAMBA 3 is:
Security no longer supports share
WARNING: Ignoring invalid value 'share 'forparameter 'security'

Configure the Samba server

Create a shared directory (assuming files under the shared/smb directory)
# Mkdir-p/smb/docs
# Mkdir-p/smb/tech

Configure Kernel Parameters
# Ulimit-n 16384
# Vi/etc/security/limits. conf
# Add the following content at the end
*-Nofile 16384

Tip: This mainly prevents the following warning information when starting Samba:
Rlimit_max: increasing rlimit_max (1024) tominimum Windows limit (16384)


# Cd/etc/samba/
// Back up the original configuration file
# Cp smb. conf smb. conf. origin

# Vi/etc/samba/smb. conf
Delete all original content and add the following content:
[Global]
Workgroup = BIGCLOUD
Netbios name = ZZSRV2
Server string = Samba Server
# Security = share
Security = user
Map to guest = Bad User
[Mongodocs]
Path =/smb/docs
Readonly = yes
Browseable = yes
Guest OK = yes
[RDDOCS]
Path =/smb/tech/
Public = no
Writable = yes
Write list = @ RD
Validusers = @ RD

Create a user and assign Permissions

// Create an operating system user
# Useraddalice
# Useraddjack
# Useradd tom
# Useradd RD

// Modify the user group
# Usermod-a-g rd alice
# Usermod-a-g rd jack
# Usermod-a-g rd tom
# Id alice
Uid = 1000 (alice) gid = 1000 (alice) groups = 1000 (alice), 1003 (RD)

// Create a SAMBA user
# Smbpasswd-a alice
# Smbpasswd-a jack
# Smbpasswd-a tom
