samba
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
3添加smb用户
首先系统中要有用户
[root@westos ~]# id student
uid=1000(student) gid=1000(student) groups=1000(student),10(wheel)
[root@westos ~]# smbpasswd -a student 创建smb用户
New SMB password:
Retype new SMB password:
Added user student.
[root@westos ~]# pdbedit -L 查看smb用户信息
student:1000:Student User
[root@westos ~]# pdbedit -x student 删除smb用户
[root@westos ~]# pdbedit -L
[root@westos ~]# setsebool -P samba_enable_home_dirs on 在selinux中可以访问自己的家目录
测试
[root@westos ~]# smbclient //172.25.254.114/student -U student
Enter student's password:
Domain=[MYGROUP] OS=[Unix] Server=[Samba 4.1.1]
smb: \> ls

4共享目录
[root@westos ~]# vim /etc/samba/smb.conf
[jj] 共享名称
comment = local.public 对共享目录的描述
path = /mnt 共享目录的绝对路径
workgroup = WESTOS 共享目录的组
当共享目录为用户自建目录时
[root@westos mnt]# mkdir /smbshare
[root@westos mnt]# touch /smbshare/westosxxx
[root@westos mnt]# vim /etc/samba/smb.conf
[jj]
comment = local.public
path = /smbshare
[root@westos mnt]# setsebool -P samba_enable_home_dirs 0
[root@westos mnt]# semanage fcontext -a -t samba_share_t '/smbshare(/.*)?'
