1、SMB介紹

Samba可以實現Linux和Windows的檔案共享     

SMB（Service Message Block）涉及的埠

smb：tcp 139 445

nmbd udp 137 138

samba使用者是系統使用者但密碼是獨立的，非/etc/shadow中的密碼，使用smbpasswd設定訪問smb的密碼。

sambclient -L Server -U username檢查伺服器上的共享

smbclient //Server/Shared -U username以互動式模式連入伺服器的某共享

smb配置檔案/etc/samba/smb.conf常用選項

[global]

interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24 指定監聽的IP、埠

hosts allow = 127. 192.168.12. 192.168.13.指定可以訪問SMB的IP

[public]

comment = Public Stuff                         

path = /home/samba         指定共享的目錄

write list = +staff                 指定只有staff組中的使用者有寫許可權

create mask = 0644                                                                修改檔案許可權

testparm測試配置檔案語法錯誤，並顯示最終生效的配置

linux掛載cifs檔案系統

mount -t cifs //Server/Shared /path/to/mount_point -o username=smbuser

2、SMB安裝配置

共享名為myshared,僅mygroup組中的使用者具有執行許可權,所有檔案不具有執行許可權，不可刪除他人上傳的檔案

yum -y install samba samba-client

[[email protected] ~]# testparm

Load smb config files from /etc/samba/smb.conf

rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)

Processing section "[myshared]"

Loaded services file OK.

Server role: ROLE_STANDALONE

Press enter to see a dump of your service definitions

[global]

        workgroup = MYGROUP

        server string = Samba Server Version %v

        log file = /var/log/samba/log.%m

        max log size = 50

        client signing = required

        idmap config * : backend = tdb

        cups options = raw

[myshared]

        comment = myshared

        path = /myshared

        write list = +mygroup

        create mask = 0644

[[email protected] ~]# 

groupadd mygroup

useradd -m userrw

useradd -m userro

usermod -a -G mygroup userrw

smbpasswd -a userrw

smbpasswd -a userro

mkdir /myshared

chown root:mygroup /myshared

chmod +t /myshared

chmod g+w /myshared

service smb start

service nmb start

chkconfig smb on

chkconfig nmb on
