####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
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

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

6smb多用户挂载
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 ~]$
