10.28 rsync 工具介绍

rsync -av /etc/passwd /tmp/1.txt
rsync -av /tmp/1.txt 192.168.188.128:/tmp/2.txt
rsync 格式
rsync [OPTION] ...SRC DEST
rsync [OPTION] ...SRC [[email protected]]host:DEST
rsync [OPTION] ...[[email protected]]host:SRC DEST
rsync [OPTION] ...SRC [[email protected]]host::DEST
rsync [OPTION] ...[[email protected]]host::SRC DEST

    [[email protected] system]# rsync -av /etc/passwd /tmp/1.txt
    sending incremental file list
    passwd

10.29 rsync 常用选项 上

rsync 常用选项
    -a   包含-rtplgoD
    -r   同步目录时要加上，类似cp时的-r选项
    -v   同步时显示一些信息，让我知道同步的过程
    -l   保留软链接
    -L   加上该选项后，同步软链接时会把源文件给同步
    -p   保持文件的权限属性
    -o   保持稳健的属主
    -g   保持文件的属组
    -D   保持设备文件信息
    -t   保持文件的时间属性
    --delete   删除DEST中SRC没有的文件
    --exclude   过滤指定文件，如 --exclude "logs" 会把文件名包含 logs 的文件或者目录过滤掉，不同步
    -P   显示同步过程，比如速率，比 -v 更加详细
    -u   加上该选项后，如果DEST中的文件比SRC新，则不同步
    -z   传输时压缩

10.31 Linux文件同步工具 rsync

rsync 通过ssh方式同步
rsync -av test1/ 192.168.133.132:/tmp/test2
rsync -avP -e "ssh -p 22" test/ 192.168.133.132:/tmp/test2/

rsync 通过服务的方式同步
要编辑配置文件 /etc/rsyncd.conf
启动服务 rsync --daemon
格式： rsync -av test1/ 192.168.133.130::module/dir/

    [[email protected] ~]# rsync -av /etc/passwd 192.168.104.165:/tmp/aming.txt
