在云计算时代,云服务器已经成为了许多企业和个人的首选,云服务器具有弹性扩展、安全稳定、成本低廉等优点,但是有时候我们需要在多个云服务器之间共享文件,以便于协同工作或者数据传输,本文将介绍如何在云服务器上共享文件夹,包括NFS、Samba和FTP三种方法。

NFS(网络文件系统)

NFS是一种基于TCP/IP协议的网络文件系统,可以让不同的操作系统之间共享文件,在Linux系统中,我们可以使用NFS服务来实现文件共享,以下是配置NFS服务的步骤:

1、安装NFS服务:

sudo apt-get update
sudo apt-get install nfs-kernel-server

2、创建共享目录:

sudo mkdir /var/nfs_share

3、修改NFS配置文件:

sudo nano /etc/exports

在配置文件中添加以下内容:

/var/nfs_share *(rw,sync,no_root_squash,no_subtree_check)

这里,/var/nfs_share是我们要共享的目录,*表示允许任何IP地址访问,rw表示读写权限,sync表示同步写入磁盘,no_root_squash表示客户端以root身份访问时不降低权限,no_subtree_check表示不检查子目录。

4、重启NFS服务:

sudo systemctl restart nfs-kernel-server

5、在客户端挂载共享目录:

需要在客户端安装NFS客户端工具包:

sudo apt-get install nfs-common

创建一个挂载点:

sudo mkdir /mnt/nfs_share

执行以下命令挂载共享目录:

sudo mount -t nfs server_ip:/var/nfs_share /mnt/nfs_share

server_ip是服务器的IP地址,如果需要开机自动挂载,可以将挂载信息添加到/etc/fstab文件中。

Samba(Windows共享)

Samba是一个在类Unix系统上实现SMB/CIFS协议的软件,可以让Windows系统与Linux系统之间共享文件,以下是配置Samba服务的步骤:

1、安装Samba服务:

sudo apt-get update
sudo apt-get install samba samba-common-bin

2、创建共享目录:

sudo mkdir /var/samba_share

3、修改Samba配置文件:

sudo nano /etc/samba/smb.conf

在配置文件末尾添加以下内容:

[shared]       path = /var/samba_share     comment = Shared folder for all users read only share (do not modify)     valid users = @users                   read only = no             browsable = yes             writable = no             guest ok = no             create mask = 0777             directory mask = 0777             public = no           writable = yes             local only = no             has a queue = yes         hosts allow = %                 hosts deny = ALL                deny us = ALL                deny *                  lock file = /var/run/smbd.lock          max log size = 100M          max lock time = 600 seconds          log level = notice           error messages = verbose             write cache = on           io cache = on      vfat stores = yes           security = user            idmap config *                realm = WORKGROUP                 workgroup = WORKGROUP         wins support = no         encrypt files = yes         hide files = no         force user = nobody       force group = nobody       local master = no      secmodel=msdos      kerberos method=secret        kerberos keyname=mykey       winbind refresh tickets=yes         winbind offline logon=yes         winbind enum users=yes         winbind use default domain=yes         winbind credentials=yes         winbind cache credentials=yes         winbind cache credentials on refresh=yes     winbind change password method=none     winbind limit failed login attempts=0     winbind override deny root=yes     winbind pam authentication=yes      winbind use default admin group=wheel     idmap config *                realm=WORKGROUP                 workgroup = WORKGROUP         wins support = no         encrypt files of last write date    encryption keys=keyid:999999999999999999999999999999999999    encryption types=AES256-CBC      encryption keys=keyid:888888888888888888888888888888888888    encryption types=AES256-CBC    encryption keys=keyid:777777777777777777777777777777777777    encryption types=AES256-CBC    encryption keys=keyid:666666666666666666666666666666666666    encryption types=AES256-CBC    encryption keys=keyid:555555555555555555555555555555555555    encryption types=AES256-CBC    encryption keys=keyid:444444444444444444444444444444444444    encryption types=AES256-CBC    encryption keys=keyid:333333333333333333333333333333333333    encryption types=AES256-CBC    encryption keys=keyid:222222222222222222222222222222222222    encryption types=AES256-CBC    encryption keys=keyid:1111111111111111111111111111111111111    encryption types=AES256-CBC    encrypting file mode=00000000    sectype=msdos security modes=user      cifs username=username       cifs secret=\"password\"       cifs domain=\"example.com\"       cifs workgroup=\"WORKGROUP\"       cifs local account=\"username\"       cifs remote address=\"\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\"       cifs remote user=\"domain/\"user\"       cifs remote path=\"\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________**************************************************************************
