smb服务
用途
实现 类unix与windows之间的文件共享
实现 打印机共享
工作原理
smb与nfs 局域网内的共享
smbd 负责文件传输与发布共享资源 TCP 139 445
nmbd 负责名称解析NetBios UDP 137 138
1.安装软件
[root@samba ~]# yum -y install samba samba-client
[root@samba ~]# yum -y install cifs-utils
2.查询软件列表
[root@samba ~]# rpm -ql samba |grep smbstatus
/usr/bin/smbstatus --smb连接状态
/usr/lib/systemd/system/nmb.service --启动脚本
/usr/lib/systemd/system/smb.service
/usr/sbin/nmbd
/usr/sbin/smbd
[root@samba ~]# rpm -ql samba-common |less
/etc/logrotate.d/samba
/etc/samba/smb.conf --主配置文件
/etc/sysconfig/samba
/usr/bin/pdbedit --查询smb用户 smb存在/etc/passwd
/usr/bin/testparm --检测语法
/var/lib/samba/private --存放smb密码
/var/log/samba --smb日志
[root@samba ~]# rpm -ql samba-client
/usr/bin/smbclient --smb远程登录工具
/usr/bin/smbpasswd --配置smb密码
3.了解samba配置文件的参数
[root@samba ~]# rpm -qd samba-common |grep 5
/usr/share/man/man5/lmhosts.5.gz
/usr/share/man/man5/smb.conf.5.gz
/usr/share/man/man5/smbpasswd.5.gz
[root@samba ~]# cat /etc/samba/smb.conf |grep -v ^# |grep -v ^$ |grep -v ^';'
[global] --全局选项
workgroup = SAMBA --工作组
security = user --认证方式
passdb backend = tdbsam --密码以数据格式存放
printing = cups
printcap name = cups
load printers = yes --默认加载所有的打印机
cups options = raw --打印机选项
[homes] --局部选项
comment = Home Directories --描述信息
valid users = %S, %D%w%S
browseable = No --隐藏
read only = No --可读写 等于 read only = No
inherit acls = Yes
[printers] --共享名称
comment = All Printers --描述信息
path = /data/database/samba --共享目录
printable = Yes --打印选项
create mask = 0600
browseable = No --隐藏
[print$]
comment = Printer Drivers
path = /var/lib/samba/drivers
write list = @printadmin root
force group = @printadmin
create mask = 0664
directory mask = 0775
配置samba服务 新建（授权）
[root@samba ~]# mkdir /data/database/samba -p
[root@samba ~]# chmod 777 /data/database/samba
发布目录
[root@samba ~]# rm -rf /etc/samba/smb.conf
[root@samba ~]# mv /etc/samba/smb.conf.example /etc/samba/smb.conf
[root@samba ~]# vim /etc/samba/smb.conf
=======================================
security = user
passdb backend = tdbsam
map to guest = Bad User （添加）
---------------------------
取消以下注释";"并修改
---------------------------
[public]
comment = This is smb share
path = /data/database/samba
public = yes
writable = yes
=======================================
