samba
一定义
提供cifs协议，可实现linux和windows的共享
二 Samba服务的组成部分
1. 软件包:
Samba-common – Samba的支持文件
Samba-client – 客户端应用程序
Samba – 服务器应用程序
2. 服务名称:smb nmb
3. 服务端口: 通常使用TCP/445进行所有连接。还使用UDP137、UDP138和TCP/139进行向后兼容
4. 主配置文件:/etc/samba/smb.conf
5 samba开启的端口：
smb：445，139
nmb：137，138
过程如下：
[root@localhost ~]# netstat -antlupe | grep smb
tcp 0 0 0.0.0.0:445 0.0.0.0:* LISTEN 0 204147 5723/smbd
tcp 0 0 0.0.0.0:139 0.0.0.0:* LISTEN 0 204148 5723/smbd
tcp6 0 0 :::445 :::* LISTEN 0 204145 5723/smbd
tcp6 0 0 :::139 :::* LISTEN 0 204146 5723/smbd
[root@localhost ~]# netstat -antlupe | grep nmb

udp 0 0 172.25.254.112:138 0.0.0.0:* 0 204097 5722/nmbd
udp 0 0 0.0.0.0:138 0.0.0.0:* 0 204093 5722/nmbd
三 samba配置
1）
1 systemctl stop firewalld.service
2 yum install samba samba-common samba-client -y
3 systemctl start smb nmb
4 systemctl enable smb.service nmb.service
在客户端，可以用smbclient -L //172.25.254.112 查看能否访问共享目录
2）samba用户的添加，必须是本地用户###
1 smbpasswd -a student
2 pdbedit-L###查看samba用户###
3 pdbedit-xsamba用户###删除samba用户###
4 getsebool -a | grep samba###查看samba的selinux###
5 setsebool -P samba_enable_home_dirs 1###开启samba用户登入自己家目录的功能###
测试：
smbclient -L //172.25.254.112 -U student###看能否访问共享目录###
smbclient //172.25.254.112/student -U student###访问samba用户的家目录###
过程如下：
samba服务端：
[root@localhost ~]# yum install samba samba-common -y
[root@localhost ~]# systemctl start smb nmb
[root@localhost ~]# systemctl enable smb.service nmb.service
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'
[root@localhost ~]# netstat -antlupe | grep smb

三 samba共享目录
samba服务端：
1)共享自己建立的目录
1 mkdir /smbshare
2 touch /smbshare/westoslinux...
3 vim /etc/samba/smb.conf###编辑samba的配置文件###
内容：
[westos]###共享名称###
comment = local directory###共享目录的描述###
path = /smbshare###共享目录的绝对路径###
4 systemctl restart smb.service###重启samba服务###
5 semanage fcontext -a -t samba_share_t '/smbshare(/.*)?'###修改安全上下文，使得所建立的目录的安全上下文与samba一致，能够访问###
6 restorecon -RvvF /smbshare/###刷新###
测试：
samba客户端：
smbclient //172.25.254.112/westos -U student
过程如下：
samba服务端：
[root@localhost ~]# mkdir /smbshare
[root@localhost ~]# touch /smbshare/westoslinux...
[root@localhost ~]# vim /etc/samba/smb.conf
[root@localhost ~]# systemctl restart smb.service
[root@localhost ~]# vim /etc/samba/smb.conf
[root@localhost ~]# systemctl restart smb.service
[root@localhost ~]# semanage fcontext -a -t samba_share_t '/smbshare(/.*)?'
[root@localhost ~]# restorecon -RvvF /smbshare/
restorecon reset /smbshare context unconfined_u:object_r:default_t:s0->system_u:object_r:samba_share_t:s0
restorecon reset /smbshare/westoslinux... context
测试：
samba客户端：
[root@foundation12 Desktop]# smbclient //172.25.254.178/westos -U student

smb: \>
2)共享系统目录
共享系统目录的时候不能将系统目录的安全上下文修改，不然系统目录的其他文件就看不到了，因此，要将selinux的samba只读功能开启
samba服务端：
1 touch /mnt/file{1..6}###建立共享目录下的文件###
2 vim /etc/samba/smb.conf
内容：
[westos]
comment = local directory
path = /mnt
3 systemctl restart smb.service###重启服务###
4 setsebool -P samba_export_all_ro 1###开启samba只读功能###
测试：
smbclient //172.25.254.112/westos -U student
过程如下：
[root@localhost mnt]# touch /mnt/file{1..6}
[root@localhost mnt]# ls
file1 file2 file3 file4 file5 file6
[root@localhost mnt]# vim /etc/samba/smb.conf
[root@localhost mnt]# systemctl restart smb.service
[root@localhost mnt]# getsebool -a | grep samba
samba_create_home_dirs --> off
samba_domain_controller --> off
samba_enable_home_dirs --> on
samba_export_all_ro --> off
samba_export_all_rw --> off
samba_portmapper --> off
samba_run_unconfined --> off
samba_share_fusefs --> off
samba_share_nfs --> off
sanlock_use_samba --> off
use_samba_home_dirs --> off
virt_sandbox_use_samba --> off
virt_use_samba --> off
[root@localhost mnt]# setsebool -P samba_export_all_ro 1
测试：
[root@foundation12 Desktop]# smbclient //172.25.254.112/westos -U student
Enter student's password:
Domain=[WESTOS] OS=[Windows 6.1] Server=[Samba 4.2.3]
smb: \> ls

八 读写控制
一般情况下，是不允许往共享目录内进行写操作，如下：
[root@localhost ~]# mount -o username=westos,password=westos //172.25.254.112/westos /mnt/将共享目录westos以samba用户westos挂载到/mnt下###
[root@localhost ~]# cd /mnt/
[root@localhost mnt]# ll
total 0
-rw-r--r--. 1 root root 0 Jun 4 21:52 file1
-rw-r--r--. 1 root root 0 Jun 4 21:52 file2
-rw-r--r--. 1 root root 0 Jun 4 21:52 file3
[root@localhost mnt]# touch file10###进行写操作###
touch: cannot touch ‘file10’: Permission denied
[root@localhost mnt]#
1)所有用户均可以写：
samba服务器：
1 vim /etc/samba/smb.conf
内容：
[westos]
comment = local directory
path = /mnt
writable = yes###允许写操作###
2 chmod o+w /mnt/###当访问共享目录的时候，用户身份发生了改变,因此要使/mnt对其他用户有权限###
3 systemctl restart smb
4 setsebool -P samba_export_all_rw on###开启读写共享功能###
测试：
客户端：
mount -o username=westos,password=westos //172.25.254.112/westos /mnt/
过程如下：
[root@localhost ~]# vim /etc/samba/smb.conf
[root@localhost ~]# ll /mnt/
total 0
-rw-r--r--. 1 root root 0 Jun 3 02:38 file1
-rw-r--r--. 1 root root 0 Jun 3 02:38 file2
-rw-r--r--. 1 root root 0 Jun 3 02:38 file3
-rw-r--r--. 1 root root 0 Jun 3 02:38 file4
-rw-r--r--. 1 root root 0 Jun 3 02:38 file5
-rw-r--r--. 1 root root 0 Jun 3 02:38 file6
[root@localhost ~]# chmod o+w /mnt/
[root@localhost ~]# setsebool -P samba_export_all_rw on
[root@localhost ~]#
测试:
[root@foundation12 ~]# mount -o username=westos,password=westos //172.25.254.112/westos /mnt/
[root@foundation12 ~]# cd /mnt/
[root@foundation12 mnt]# ls
file1 file2 file3 file4 file5 file6
[root@foundation12 mnt]# touch file7
[root@foundation12 mnt]# ls
file1 file2 file3 file4 file5 file6 file7
[root@foundation12 mnt]# ls -l file7
-rw-r--r-- 1 1001 1001 0 Jun 3 15:51 file7
[root@foundation12 mnt]# ll file7
-rw-r--r-- 1 1001 1001 0 Jun 3 15:51 file7
[root@foundation12 mnt]#
2）指定用户可以写：
samba服务端：
1 vim /etc/samba/smb.conf
内容：
[westos]
comment=local directory
path = /mnt
writable = no
write list = student###指定只有samba的student用户可以写，若是@（+）student则是指指定用户组可以写###
2 systemctl restart smb
测试:
mount -o username=westos,password=westos //172.25.254.178/westos /mnt/###查看westos用户是否可写###
mount -o username=student,password=student //172.25.254.178/westos /mnt/###查看student用户是否可写###
过程如下：
[root@desktop ~]# vim /etc/samba/smb.conf
[root@desktop ~]# systemctl restart smb
图
测试：
[root@localhost ~]# mount -o username=westos,password=westos //172.25.254.178/westos /mnt/
[root@localhost ~]# cd /mnt/
[root@localhost mnt]# ls

[root@localhost mnt]# cd
[root@localhost ~]# umount /mnt/
[root@localhost ~]# mount -o username=student,password=student //172.25.254.178/westos /mnt/

九 共享的超级用户指定
在客户端访问共目录并且进行写操作时，用户身份发生了变化，变成了当前的登入的samba用户，当共享目录的超级用户指定时，用该samba用户进行写操作时，就变成了超级用户的操作
samba服务端：
1 vim /etc/samba/smb.conf
内容：
[westos]
comment = local directory
path = /mnt
writable = yes
admin users = westos
2 systemctl restart smb
测试：
客户端：
1 chmod o-w /mnt/###使共享目录只对超级用户有写权限###
2 mount -o username=westos,password=westos //172.25.254.112/westos /mnt/###挂载共享目录到/mnt下###
过程如下：
samba服务端：
[root@desktop ~]# vim /etc/samba/smb.conf
[root@desktop ~]# systemctl restart smb
[root@desktop ~]# chmod o-w /mnt/
测试：
[root@localhost ~]# mount -o username=westos,password=westos //172.25.254.178/westos /mnt/
[root@localhost ~]# cd /mnt/

十 多用户挂载
当把共享目录挂载到本机的目录上的时侯，普通用户也可以访文该共享目录，因此，要进行多用户挂载，只有smb认证的才能访问smb共享目录
在客户端进行操作：
1 vim /root/westos###编写用户文件，文件名任意，指定挂载时要用###
内容：
username=westos###samba用户名###
password=westos###samba用户的密码###
2 chmod 600 /root/westos###只有超级用户可以读取该文件###
3 yum install cifs-utils -y
4 mount -o credentials=/root/westos,multiuser,sec=ntlmssp //172.25.254.112/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
测试：
过程如下：
[root@foundation12 Desktop]# mount -o credentials=/root/westos,multiuser,sec=ntlmssp //172.25.254.112/westos /mnt/
[root@foundation12 Desktop]# cd /mnt/
[root@foundation12 mnt]# ls
file1 file10 file2 file3 file4 file5 file6 file7 file8 file9
[root@foundation12 mnt]# su - kiosk

[kiosk@foundation12 mnt]$ ls
ls: reading directory .: Permission denied###没有smb认证无法访问共享目录###
[kiosk@foundation12 mnt]$ cifscreds add -u student 172.25.254.112###使得该普通用户kiosk能够以samba用户student的身份去访问samba共享目录###
Password:
[kiosk@foundation12 mnt]$ ls

[kiosk@foundation12 mnt]$
