实际上日常使用中，经常用\ip地址目录来访问局域网的共享文件，这都归功于smb协议
SMB（Server Message Block）通信协议是微软（Microsoft）和英特尔(Intel)在1987年制定的协议，主要是作为Microsoft网络的通讯协议。SMB 是在会话层（session layer）和表示层（presentation layer）以及小部分应用层（application layer）的协议。

samba是linux对smb协议的一种实现
Samba是在Linux和UNIX系统上实现SMB协议的一个免费软件，由服务器及客户端程序构成。SMB（Server Messages Block，信息服务块）是一种在局域网上共享文件和打印机的一种通信协议，它为局域网内的不同计算机之间提供文件及打印机等资源的共享服务。SMB协议是客户机/服务器型协议，客户机通过该协议可以访问服务器上的共享文件系统、打印机及其他资源。通过设置“NetBIOS over TCP/IP”使得Samba不但能与局域网络主机分享资源，还能与全世界的电脑分享资源。

安装samba
yum install samba samba-client -y
安装完后就可以在/etc/samba下找到samba的配置，详细的配置可以参考smb.conf.example
# This is the main Samba configuration file. For detailed information about the # options listed here, refer to the smb.conf(5) manual page. Samba has a huge # number of configurable options, most of which are not shown in this example. # # The Samba Wiki contains a lot of step-by-step guides installing, configuring, # and using Samba: # https://wiki.samba.org/index.php/User_Documentation # # In this file, lines starting with a semicolon (;) or a hash (#) are # comments and are ignored. This file uses hashes to denote commentary and # semicolons for parts of the file you may wish to configure. # # NOTE: Run the "testparm" command after modifying this file to check for basic # syntax errors. # #--------------- # Security-Enhanced Linux (SELinux) Notes: # # Turn the samba_domain_controller Boolean on to allow a Samba PDC to use the # useradd and groupadd family of binaries. Run the following command as the # root user to turn this Boolean on: # setsebool -P samba_domain_controller on # # Turn the samba_enable_home_dirs Boolean on if you want to share home # directories via Samba. Run the following command as the root user to turn this # Boolean on: # setsebool -P samba_enable_home_dirs on # # If you create a new directory, such as a new top-level directory, label it # with samba_share_t so that SELinux allows Samba to read and write to it. Do # not label system directories, such as /etc/ and /home/, with samba_share_t, as # such directories should already have an SELinux label. # # Run the "ls -ldZ /path/to/directory" command to view the current SELinux # label for a given directory. # # Set SELinux labels only on files and directories you have created. Use the # chcon command to temporarily change a label: # chcon -t samba_share_t /path/to/directory # # Changes made via chcon are lost when the file system is relabeled or commands # such as restorecon are run. # # Use the samba_export_all_ro or samba_export_all_rw Boolean to share system # directories. To share such directories and only allow read-only permissions: # setsebool -P samba_export_all_ro on # To share such directories and allow read and write permissions: # setsebool -P samba_export_all_rw on # # To run scripts (preexec/root prexec/print command/...), copy them to the # /var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them. # Note that if you move the scripts to /var/lib/samba/scripts/, they retain # their existing SELinux labels, which may be labels that SELinux does not allow # smbd to run. Copying the scripts will result in the correct SELinux labels. # Run the "restorecon -R -v /var/lib/samba/scripts" command as the root user to # apply the correct SELinux labels to these files. # #-------------- # #======================= Global Settings ===================================== [global] # ----------------------- Network-Related Options ------------------------- # # workgroup = the Windows NT domain name or workgroup name, for example, MYGROUP. # # server string = the equivalent of the Windows NT Description field. # # netbios name = used to specify a server name that is not tied to the hostname, # maximum is 15 characters. # # interfaces = used to configure Samba to listen on multiple network interfaces. # If you have multiple interfaces, you can use the "interfaces =" option to # configure which of those interfaces Samba listens on.

简单的用起来，实际上就是能访问共享文件夹，控制用户可读可写就可以了
针对用户，此处就不赘述，只提供一个简单的demo，编辑配置文件
vim smb.conf
中括号：共享目录名
comment：描述
path：共享目录的绝对路径
read only：是否只读
添加好保存就可以在用了
