用于替代rcp的一个工具,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,则可以通过进行文件传输,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; 二、rsync常用参数 ...
Question:When I perform rsync, it asks for my password on the remote server before starting the transfer. I would like to avoid this, and perform rsync without password. Can you explain with an example on how to setup rsync over ssh without password on Linux? Answer:The following steps exp...
在客户机上创建一个rsync.password文件,并写入虚拟账号密码 [root@centos ~]#vim /etc/rsync.password 2. 修改文件权限 [root@centos ~]#chmod 600 /etc/rsync.password 测试 [root@client ~]# mkdir /backup [root@client backup]# touch {1..5} [root@client ~]#rsync -avzP /backup/ rsync_backup@...
2,使用ssh-copy-id将公匙拷贝至远程主机 #ssh-copy-id-i /root/.ssh/id_rsa.pub10.192.23.244root@10.192.23.244's password:Now try logging into the machine, with"ssh '10.192.23.244'", and checkin: .ssh/authorized_keys tomakesure we haven't added extra keys that you weren't expecting. 3...
Well, thats it. Now you can runscp,sshandrsynconhost_srcconnecting tohost_destand it won't prompt for the password. Note that this will still prompt for the password if you are running the commands onhost_destconnecting tohost_src. You can reverse the steps above (generate the public ke...

Rsync是一款不错的文件免费同步软件,可以镜像保存整个目录树和文件系统,同时保持原来文件的权限、时间、软硬链接。第一次同步时 rsync 会复制全部内容,下次只传输修改过的文件部分。传输数据过程中可以实行压缩及解压缩操作,减少带宽流量。支持scp、ssh及直接socket方式连接,支持匿名传输。支持Linux,Window平台。
2、借助rcp,ssh等通道来传输数据(此时类似于 scp 的功能) 3、以守护进程方式传输数据(rsync 自身的重要功能) # 本地数据同步方式 Local: rsync [OPTION...] SRC... [DEST] # 远程数据同步方式 Access via remote shell: Pull: rsync [OPTION...] [USER@]HOST:SRC... [DEST] Push: rsync [OPTION.....
2、scp实现免密码文件同步:此方式采用scp定时复制,实现server和client的文件同步,但需要实现服务器之间的免密码登录服务器,弊端在于需要修改服务器的SSH核心配置项,这在某些场合中是被禁止的。 3、ftp实现文件同步:ftp实现的同步属于弱同步,不能严格意义上实现文件的同步(文件的增加和修改可以实现严格意义的一直,但删除...
