一、Linux下搭建smb服务
1、安装服务 # yum install samba samba-common -y # useradd -s /sbin/nologin george --创建samba服务登录用户 # smbpasswd -a george --将用户 george 设置为smb用户，并增加密码；修改密码时不用加 -a 参数，george必须是系统已经拥有的用户 # smbpasswd -x u1 --删除用户 # smbpasswd -d u1 --禁用用户 # smbpasswd -e u1 --启用用户 # pdbedit -L --列出所有用户 # pdbedit -Lv --列出所有用户的详细信息 # pdbedit -Lv george --列出用户 george 的详细信息 2、配置文件 /etc/samba/smb.conf #######在最下端添加 [share] --共享名称 path = /share --共享路径 write list = harry --指定可以读写的用户 3、重启服务 service smb restart
二、smb.conf示例
[global] display charset = UTF8 dos charset = cp950 unix charset = UTF8 log file = /var/log/samba/log.%m max log size = 50 security = user map to guest = Bad User passdb backend = tdbsam load printers = no username map = /etc/samba/smbusers [printers] comment = All Printers path = /var/tmp printable = Yes create mask = 0600 browseable = No [print$] comment = Printer Drivers path = /var/lib/samba/drivers write list = @printadmin root force group = @printadmin create mask = 0664 directory mask = 0775 [v213735532343] comment=export of v213735532343 path=/nfs/v213735532343 writable=yes browseable=no posix locking=no valid users=%U hide unreadable = yes
三、Java开发smb协议相关接口
1.在pom.xml文件夹中添加如下的依赖
<dependency>
<groupId>jcifs</groupId>
<artifactId>jcifs</artifactId>
<version>1.3.17</version>
</dependency>
2.交互代码
import jcifs.smb.*;
import java.io.*;
import java.net.MalformedURLException;
