1. ssh

1.1. 安装

sudo apt install openssh-server # 服务端sudo apt install openssh-client # 客户端

1.2. 使用

# 启动ssh服务
sudo /etc/init.d/ssh start# 设置开机自启动
sudo systemctl enable ssh# 关闭ssh开机自动启动命令
sudo systemctl disable ssh# 单次开启ssh
sudo systemctl start ssh# 单次关闭ssh
sudo systemctl stop ssh

1.3. 远程文件夹挂载到本地

 sshfs administrator@310.20.222.46:~/administrator/ admin

1.4. 远程连接

ssh administrator@310.25.210.17

1.5. 快捷使用

在~/.ssh/config中添加

Host PCHostName 110.15.126.45User hehe

使用

ssh PC

2. scp

远程文件传送到本地

传文件
scp administrator@310.25.210.17:~/test.txt . 传文件夹
scp -r administrator@310.25.210.17:~/test .

本地文件传送到远程

传文件
scp test.txt administrator@310.25.210.17:~/传文件夹
scp -r test administrator@310.25.210.17:~/

如果警告中间人攻击则使用下面命令

ssh-keygen -R 310.25.218.17

3. rsync

3.1. 介绍

rsync（remote synchronize）是一个远程数据同步工具，可通过LAN/WAN快速同步多台主机间的文件。rsync使用所谓的“rsync算法”来使本地和远程两个主机之间的文件达到同步，这个算法只传送两个文件的不同部分，而不是每次都整份传送，因此速度相当快。rsync支持大多数的类Unix系统，无论是Linux、Solaris还是BSD上都经过了良好的测试。此外，它在windows平台下也有相应的版本，如cwRsync和Sync2NAS等工具。

rsync本来是用于替代rcp的一个工具，目前由rsync.samba.org维护，所以rsync.conf文件的格式类似于samba的主配置文件；rsync可以通过rsh或ssh使用，也能以daemon模式去运行。

在以daemon方式运行时Rsync server会打开一个873 端口，等待客户端去连接。连接时，rsync server会检查口令是否相符，若通过口令查核，则可以开始进行文件传输。第一次连通完成时，会把整份文件传输一次，以后则就只需进行增量备份。

rsync 具有以下特点

可以镜像保存整个目录树和文件系统；

可以很容易做到保持原来文件的权限、时间、软硬链接等；

无须特殊权限即可安装；

优化的流程，文件传输效率高；

可以使用rsh、ssh等方式来传输文件，当然也可以通过直接的socket连接；

支持匿名传输

3.2. 使用

Usage:
rsync [OPTION]... SRC [SRC]... DEST
rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
rsync [OPTION]... [USER@]HOST:SRC [DEST]
rsync [OPTION]... [USER@]HOST::SRC [DEST]
rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.

例如

rsync -av /backup/ -e ssh root@192.168.1.110:/bak
#-a: archive归档模式，表示以递归方式传输文件，并保持所有文件属性，链接等,等于-rlptgoD
#-v: 显示详细信息

3.4. 与SCP的区别

rsycn强调的是同步，scp强调的是传输

sync和scp在文件夹均不存在时，执行时间相差不大，但是文件夹存在的情况下差异很大。原因是scp是复制：若mas2文件不存在则新建，若存在则覆盖，若mas2上有而Dashboard主机没有，则不改变。可以理解为scp为“复制”。而rsync则在文件在存在于两主机时，比较两文件是够相同，相同的话，就什么都不做，若存在差异就直接更新。

简单的说rsync只对差异文件做更新。
