文件共享之samba

1.samba作用：
  提供cifs協議實現共享文件，

2.安裝
[root@desktop ~]# yum install samba samba-common samba-client -y
samba 主服務
samba-common   命令
samba-client   客戶測試
[root@desktop ~]# systemctl start smb nmb                   ##啓動服務
[root@desktop ~]# systemctl enable smb nmb
ln -s '/usr/lib/systemd/system/smb.service' '/etc/systemd/system/multi-user.target.wants/smb.service'
ln -s '/usr/lib/systemd/system/nmb.service' '/etc/systemd/system/multi-user.target.wants/nmb.service'


3.添加samba用戶
smb用戶必須是本地用戶
[root@desktop ~]# smbpasswd -a student                ##添加student用戶（該用戶在本地用戶中）
New SMB password:
Retype new SMB password:
Added user student.
[root@desktop ~]# pdbedit -L                                   ##查詢用戶是否建立成功
student:1000:Student User

4.文件共享
****共享用戶家目錄****
[root@desktop ~]# setsebool -P samba_enable_home_dirs on  ##在selinux中設定smb用戶可以訪問自己家目錄
[root@desktop ~]# smbclient //172.25.254.140/student -U student  ##登錄smb用戶student
Enter student's password:
Domain=[MYGROUP] OS=[Unix] Server=[Samba 4.1.1]
smb: \> ls

****共享新建目錄時****
[root@desktop ~]# mkdir /biubiubiu
[root@desktop ~]# touch /biubiubiu/lilili
[root@desktop ~]# vim /etc/samba/smb.conf                      ##編寫主配置文件，在末尾添加
    [haha]
    comment = local
    path = /biubiubiu
[root@desktop ~]# setsebool -P samba_enable_home_dirs 0        ##關閉smb用戶對用戶家目錄的訪問
[root@desktop ~]# smbclient //172.25.254.140/haha -U student
Enter student's password:
