访问网络文件共享服务

1.访问网络共享的三个基本步骤

   1）识别要访问的远程共享

   2）确定挂载点 ( 应该将共享挂载到的位置 ), 并创建挂载点的空目录

   3）通过相应的名利或配置更改挂载网络文件系统

2.CIFS( Comon Internet File System ) 协议


   是针对 MicrosoftWindows 系统的标准网络文件系统

   **需要下载服务客户端：yum install samba-client -y

   [root@localhost mnt]# smbclient -L //172.25.254.250                          ##列出已分享的文件系统

Enter root's password:

3.NFS ( Network File System )  协议


   可看作是 Linux 、UNIX 及其它类似操作系统的标准文件系统

   **需要下载服务客户端：yum install nfs-utils -y

[root@localhost ~]# showmount -e 172.25.254.250                                ##显示已识别的文件系统

Export list for 172.25.254.250:

/content       172.25.0.0/255.255.0.0

[root@localhost ~]# mount 172.25.254.250:/nfsshare/nfs1 /mnt           ##挂载文件系统
