访问网络文件共享服务

来源：互联网发布：网站源码基地编辑：程序博客网时间：2024/05/16 16:11

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:
Domain=[MYGROUP] OS=[Unix] Server=[Samba 4.1.1]

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

/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
[root@localhost ~]# df
