1、SMB介绍
Samba可以实现Linux和Windows的文件共享
SMB（Service Message Block）涉及的端口
smb：tcp 139 445
nmbd udp 137 138
samba用户是系统用户但密码是独立的，非/etc/shadow中的密码，使用smbpasswd设置访问smb的密码。
sambclient -L Server -U username检查服务器上的共享
smbclient //Server/Shared -U username以交互式模式连入服务器的某共享
smb配置文件/etc/samba/smb.conf常用选项
[global]
interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24 指定监听的IP、端口
hosts allow = 127. 192.168.12. 192.168.13.指定可以访问SMB的IP
[public]
comment = Public Stuff 共享的备注信息
path = /home/samba 指定共享的目录
write list = +staff 指定只有staff组中的用户有写权限
create mask = 0644 修改文件权限
testparm测试配置文件语法错误，并显示最终生效的配置
linux挂载cifs文件系统
mount -t cifs //Server/Shared /path/to/mount_point -o username=smbuser
2、SMB安装配置
共享名为myshared,仅mygroup组中的用户具有执行权限,所有文件不具有执行权限，不可删除他人上传的文件
yum -y install samba samba-client
[root@localhost ~]# 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
[root@localhost ~]#
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
