1samba作用

提供cifs协议实现共享文件

2安装

yum install samba samba-common samba-client -y

systemctl start smb nmb

systemctl enable smb nmb

systemctl stop firewalld.service

3添加smb用户

smb用户必须是本地用户

smbpasswd -a student

New SMB password:                   #输入smb当前用户密码

Retype new SMB password:#确认密码

Added user student.

pdbedit -L#查看smb用户信息

student:1000:Student User  

pdbedit -x student#删除smb用户

setsebool -P samba_enable_home_dirs on  ##在selinux中设定smb用户可以访问自己的家目录

4共享目录的基本设定

117

mkdir /smbshare

touch /smbshare/123

vim /etc/samba/smb.conf

321         [westos]      ##共享名称

322         comment = local directory   ##对共享目录的描述

323         path = /smbshare     ##共享目录的绝对路径

当共享目录为用户自建目录时

semanage fcontext -a -t samba_share_t '/smbshare(/.*)?'

restorecon -Rvvf /smbshare/

systemctl restart smb.service

测试

[root@DNS-server 桌面]# smbclient //172.25.254.117/westos -U student

Enter student's password:

Domain=[MYGROUP] OS=[Unix] Server=[Samba 4.1.1]

smb: \> ls

10473900 blocks of size 1024. 7316272 blocks available

smb: \> SMBecho failed (NT_STATUS_CONNECTION_DISCONNECTED). The connection is disconnected now

当共享目录为系统建立目录

setsebool -P samba_export_all_ro on#只读共享

setsebool -P samba_export_all_rw on#读写共享

systemctl restart smb.service

在client(客户端)上

vim /root/haha

username=student

password=123     ##密码为smb密码

chmod 600 /root/haha

yum install cifs-utils.x86_64  -y

mount -o credentials=/root/haha,multiuser,sec=ntlmssp //172.25.254.117/westos /mnt/

#credentials=/root/haha  指定挂载时所用到的用户文件

#multiuser        支持多用户认证

#sec=ntlmssp认证方式为标准smb认证方式

[root@localhost ~]# su - westos

[westos@localhost ~]$ ls /mnt

ls: cannot access /mnt: Permission denied   #因为没有作smb的认证所以无法访问smb的共享

[westos@localhost ~]$ cifscreds add -u westos 172.25.254.117

Password:##smb用户westos的密码

[westos@localhost ~]$ ls /mnt

123  1234fref  file3  file5  file6

[westos@localhost ~]$
