Windows访问Linux共享文件(夹)，Linux中Samba的安装

samba安装：
检查安装了samba：rpm -qa | grep samba

在光盘(redhat系统安装盘)中查找samba的rpm文件路径：[root@yangfan /]# find -name samba*

按顺序安装samba的rpm文件：
[root@yangfan Packages]# rpm -ivh samba-3.5.10-125.el6.x86_64.rpm
warning: samba-3.5.10-125.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY

启动samba：service smb start

重行运行Linux Samba：终端运行命令 service smb restart

关闭samba：
[root@yangfan /]# service smb stop
Shutting down SMB services:                                [  OK  ]

关闭防火墙：iptables -F

添加一个samba账号：//注意bill必须是已经存在的linux账号
[root@yangfan /]# smbpasswd -a bill
New SMB password:billsmb
Retype new SMB password:billsmb
Added user bill.

不能在共享目录创建文件解决方法：
/etc/selinux/config中修改
#SELINUX=enforcing
SELINUX=disabled
