上学的时候在学校机房见过FTP做的文件分享系统，服务器是Windows的，当时感觉功能真的很强大，不管是哪台机器都可以共享一个文件夹，后来自己在家里通过查阅各种资料，用自己的win7做FTP服务器，做了一个文件服务器，但是真的很鸡肋，操作体验真的不尽人意。

下面介绍的是Linux服务器平台安装的文件分享系统软件Samba,通过Samba部署的文件分享系统可以兼容Mac、Linux和Windows三大主流操作系统，而且操作体验也非常好，自己在家里做了一个小型分享系统，家用服务器的配置：CPU:凌动 D2500，2G内存，32G SSD的一个小型服务器，4m带宽,速度秒杀FTP，文件上传和下载都在11M/s左右。

下面简单介绍一下CentOS下yum安装过程，如果是在公司内部用，一般会编译安装samba,然后会做一些细节的权限验证，我做家用，能用就可以了，如果你想做更细节的权限分配，去度娘，参考资料好几mol。

安装：

\[root@jhq0229 ~\]\# yum install samba samba-client samba-swat

设置smb和nmb在3、5启动级别随系统启动：

\[root@jhq0229 ~\]\# chkconfig --level 35 smb on

\[root@jhq0229 ~\]\# chkconfig --level 35 nmb on

配置Samba：

\[root@jhq0229 ~\]\# vim /etc/samba/smb.conf

进行如下修改：

#======================= Global Settings =====================================
    
    [global]
    
    config file = /usr/local/samba/lib/smb.conf.%m
    
    # ----------------------- Network Related Options -------------------------
    #
    # workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH
    #
    # server string is the equivalent of the NT Description field
    #
    # netbios name can be used to specify a server name not tied to the hostname
    #
    # Interfaces lets you configure Samba to use multiple interfaces
    # If you have multiple network interfaces then you can list the ones
    # you want to listen on (never omit localhost)
    #
    # Hosts Allow/Hosts Deny lets you restrict who can connect, and you can
    # specifiy it as a per share option as well
    #
            workgroup = MYGROUP
            server string = Samba Server Version %v
    
    ;       netbios name = MYSERVER
    
            interfaces = lo eth0 192.168.1.11/24 192.168.1.1/255
    
            hosts allow = 127. 192.168.1. 192.168.0.
    
    # --------------------------- Logging Options -----------------------------
    #
    # Log File let you specify where to put logs and how to split them up.
    #
    # Max Log Size let you specify the max size log files should reach
    
            # logs split per machine
            log file = /var/log/samba/log.%m
            # max 50KB per log file, then rotate
            max log size = 50
    
    # ----------------------- Standalone Server Options ------------------------
    #
    # Scurity can be set to user, share(deprecated) or server(deprecated)
    #
    # Backend to store user information in. New installations should 
    # use either tdbsam or ldapsam. smbpasswd is available for backwards 
    # compatibility. tdbsam requires no further configuration.

    # ----------------------- Domain Members Options ------------------------
    #
    # Security must be set to domain or ads
    #
    # Use the realm option only with security = ads
    # Specifies the Active Directory realm the host is part of
    #
    # Backend to store user information in. New installations should 
    # use either tdbsam or ldapsam. smbpasswd is available for backwards 
    # compatibility. tdbsam requires no further configuration.
    #
    # Use password server option only with security = server or if you can't
    # use the DNS to locate Domain Controllers
    # The argument list may include:
    #   password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]
    # or to auto-locate the domain controller/s
    #   password server = *
    
    
    ;       security = domain
    ;       passdb backend = tdbsam
    ;       realm = MY_REALM
    
    ;       password server = <NT-Server-Name>
    
    # ----------------------- Domain Controller Options ------------------------
    #
    # Security must be set to user for domain controllers
    # use either tdbsam or ldapsam. smbpasswd is available for backwards 
    # compatibility. tdbsam requires no further configuration.
    #
    # Domain Master specifies Samba to be the Domain Master Browser. This
    # allows Samba to collate browse lists between subnets. Don't use this
    # if you already have a Windows NT domain controller doing this job
    #
    # Domain Logons let Samba be a domain logon server for Windows workstations. 
    #
    # Logon Scrpit let yuou specify a script to be run at login time on the client
    # You need to provide it in a share called NETLOGON
    #
    # Logon Path let you specify where user profiles are stored (UNC path)
    #
    # Various scripts can be used on a domain controller or stand-alone
    # machine to add or delete corresponding unix accounts
    #
    ;       security = user

    ;       delete group script = /usr/sbin/groupdel "%g"
    
    
    # ----------------------- Browser Control Options ----------------------------
    #
    # set local master to no if you don't want Samba to become a master
    # browser on your network. Otherwise the normal election rules apply
    #
    # OS Level determines the precedence of this server in master browser
    # elections. The default value should be reasonable
    #
    # Preferred Master causes Samba to force a local browser election on startup
    # and gives it a slightly higher chance of winning the election
    ;       local master = no
    ;       os level = 33
    ;       preferred master = yes
    
    #----------------------------- Name Resolution -------------------------------
    # Windows Internet Name Serving Support Section:
    # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
    #
    # - WINS Support: Tells the NMBD component of Samba to enable it's WINS Server
    #
    # - WINS Server: Tells the NMBD components of Samba to be a WINS Client
    #
    # - WINS Proxy: Tells Samba to answer name resolution queries on
    #   behalf of a non WINS capable client, for this to work there must be
    #   at least one        WINS Server on the network. The default is NO.
    #
    # DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
    # via DNS nslookups.
    
    ;       wins support = yes
    ;       wins server = w.x.y.z
    ;       wins proxy = yes
    
    ;       dns proxy = yes
    
    # --------------------------- Printing Options -----------------------------
    #
    # Load Printers let you load automatically the list of printers rather
    # than setting them up individually
    #
    # Cups Options let you pass the cups libs custom options, setting it to raw
    # for example will let you use drivers on your Windows clients
    #
    # Printcap Name let you specify an alternative printcap file
    #
    # You can choose a non default printing system using the Printing option
    
            load printers = yes
            cups options = raw
    
    ;       printcap name = /etc/printcap
            #obtain list of printers automatically on SystemV
    ;       printcap name = lpstat
    ;       printing = cups
    
    # --------------------------- Filesystem Options ---------------------------
    #
    # The following options can be uncommented if the filesystem supports
    # Extended Attributes and they are enabled (usually by the mount option
    # user_xattr). Thess options will let the admin store the DOS attributes
    # in an EA and make samba not mess with the permission bits.
    #
    # Note: these options can also be set just per share, setting them in global
    # makes them the default for all shares
    
    ;       map archive = no
    ;       map hidden = no
    ;       map read only = no
    ;       map system = no
    ;       store dos attributes = yes
    
    
    #============================ Share Definitions ==============================
    
    [homes]
            comment = Home Directories
            browseable = no
            writable = yes
    ;       valid users = %S

    [printers]
            comment = All Printers
            path = /var/spool/samba
            browseable = no
            guest ok = no
            writable = no
            printable = yes
    
    # Un-comment the following and create the netlogon directory for Domain Logons
    ;       [netlogon]
    ;       comment = Network Logon Service
    ;       path = /var/lib/samba/netlogon
    ;       guest ok = yes
    ;       writable = no
    ;       share modes = no
    
    
    # Un-comment the following to provide a specific roving profile share
    # the default is to use the user's home directory
    ;       [Profiles]
    ;       path = /var/lib/samba/profiles
    ;       browseable = no
    ;       guest ok = yes
    
    
    # A publicly accessible directory, but read only, except for people in
    # the "staff" group
            [public]
            comment = Public Stuff
            path = /share
            public = yes
            writable = yes
            printable = no
            write list = +staff

建立共享文件夹并分配nobody权限：

\[root@jhq0229 ~\]\# mkdir /share

\[root@jhq0229 ~\]\# chown -R nobody:nobody /share

关闭防火墙：

\[root@jhq0229 ~\]\# chkconfig iptables off

关闭selinux:

\[root@jhq0229 ~\]\# vim /etc/sysconfig/selinux

修改为：

#SELINUX=enforcing
    SELINUX=disabled

重启：

\[root@jhq0229 ~\]\# init 6

重启完成后，就可以通过局域网内的电脑连接共享目录了，如Windows:
