第12章 使用Samba或NFS实现文件共享

12.1 SAMBA文件共享服务

[root@linuxprobe ~ ]# yum install samba

[root@linuxprobe ~]# cat /etc/samba/smb.conf 

[root@linuxprobe ~]# mv /etc/samba/smb.conf /etc/samba/smb.conf.bak
[root@linuxprobe ~]# cat /etc/samba/smb.conf.bak | grep -v "#" | grep -v ";" | grep -v "^$" > /etc/samba/smb.conf
[root@linuxprobe ~]# cat /etc/samba/smb.conf

表12-1 Samba服务程序中的参数以及作用

[global]		#全局参数。
	workgroup = MYGROUP	#工作组名称
	server string = Samba Server Version %v	#服务器介绍信息，参数%v为显示SMB版本号
	log file = /var/log/samba/log.%m	#定义日志文件的存放位置与名称，参数%m为来访的主机名
	max log size = 50	#定义日志文件的最大容量为50KB
	security = user	#安全验证的方式，总共有4种
	#share：来访主机无需验证口令；比较方便，但安全性很差
	#user：需验证来访主机提供的口令后才可以访问；提升了安全性
	#server：使用独立的远程主机验证来访主机提供的口令（集中管理账户）
	#domain：使用域控制器进行身份验证
	passdb backend = tdbsam	#定义用户后台的类型，共有3种
	#smbpasswd：使用smbpasswd命令为系统用户设置Samba服务程序的密码
	#tdbsam：创建数据库文件并使用pdbedit命令建立Samba服务程序的用户
	#ldapsam：基于LDAP服务进行账户验证
	load printers = yes	#设置在Samba服务启动时是否共享打印机设备
	cups options = raw	#打印机的选项
[homes]		#共享参数
	comment = Home Directories	#描述信息
	browseable = no	#指定共享信息是否在“网上邻居”中可见
	writable = yes	#定义是否可以执行写入操作，与“read only”相反
[printers]		#打印机共享参数
	comment = All Printers
	path = /var/spool/samba	#共享文件的实际路径(重要)。
	browseable = no
	guest ok = no	#是否所有人可见，等同于"public"参数。
	writable = no
	printable = yes

[root@linuxprobe ~]# mv /etc/samba/smb.conf /etc/samba/smb.conf.bak
[root@linuxprobe ~]# cat /etc/samba/smb.conf.bak | grep -v "#" | grep -v ";" | grep -v "^$" > /etc/samba/smb.conf
[root@linuxprobe ~]# cat /etc/samba/smb.conf

12.1.1 配置共享资源

表12-2 用于设置Samba服务程序的参数以及作用

参数	作用
[database]	共享名称为database
comment = Do not arbitrarily modify the database file	警告用户不要随意修改数据库
path = /home/database	共享目录为/home/database
public = no	关闭“所有人可见”
writable = yes	允许写入操作

12.3 AutoFs自动挂载服务

[root@linuxprobe ~]# yum install autofs

[root@linuxprobe ~]# vim /etc/auto.master
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#
/media /etc/iso.misc
/misc /etc/auto.misc
#
# NOTE: mounts done from a hosts map will be mounted with the
# "nosuid" and "nodev" options unless the "suid" and "dev"
# options are explicitly given.
#
/net -hosts
#
# Include /etc/auto.master.d/*.autofs
#
+dir:/etc/auto.master.d
#
# Include central master map if it can be found using
# nsswitch sources.
#
# Note that if there are entries for /net or /misc (as
# above) in the included master map any keys that are the
# same will not be seen as the first read key seen takes
# precedence.
#
+auto.master

[root@linuxprobe ~]# vim /etc/iso.misc
iso   -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom
[root@linuxprobe ~]# systemctl start autofs 
[root@linuxprobe ~]# systemctl enable autofs
