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：

[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=enforcingSELINUX=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:
连接分享目录：Win键+R，然后键入\\IP地址\,如：\\192.168.1.18\,结果如下图：
唯有斯人面上簌簌流下的，是点点无声无行的热泪。
