Samba 建立服务器基于用户验证方式的共享目录(注意：服务器采用用户验证)
任务说明：
1、服务器采用用户验证的方式
2、建立一个group1的文件夹，并且只有用户group1才有权访问并读写。
3、建立一个gp1的目录，只有group1组的用户可以访问并读写
4、建立一个gp2的目录，group1组和group2组的用户都可以读，但只有group2组的用户有权写
5、建立一个公共的只读文件夹public，所有人只读这个文件夹的内容；
1.添加组，并为组添加用户
#groupadd group1
#groupadd group2
#useradd -g group1 group1
#useradd -g group1 user1
#useradd -g group1 user2
#useradd -g group2 group2
#useradd -g group2 user3
#useradd -g group2 user4
#smbpasswd -a group1
#smbpasswd -a group2
#smbpasswd -a user1
#smbpasswd -a user2
#smbpasswd -a user3
#smbpasswd -a user4
2.修改配置文件:smb.conf
debian:~# vi /etc/samba/smb.conf
[global]
security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd
[homes]
comment = home directories
browseable = no
writeable = yes
valid users = %S
create mode = 0664
directory mode = 0775
[public]
comment = public's directory
path = /home/public
public = yes
writeable = no
[group1]
path = /home/group1
comment = group1's diterctory
public = no
writeable = yes
valid users = group1
[gp1]
path = /home/gp1
comment = gp1's diterctory
public = no
valid users = @group1
write list = @group1
[gp2]
path = /home/gp2
comment = gp2's diterctory
public = no
valid users = @group1,@group2
write list = group2
