rsync文件同步工具介绍

rsync工具可以用来同步文件，比如a目录到b目录，a机器到b机器，（多次同步，可以只同步变动的文件）

例：rsync -av /etc/passwd /tmp/1.txt 同步passwd到1.txt中，-v可视化

rsync -av /etc/passwd  root@192.168.133.130:/tmp/1.txt 远程同步

root@可省略，默认是当前登录用户

常用选项

[root@g_linux01 ~]# rsync -av /root/soft/ /tmp/test_dest/sending incremental file list./1.txt2.txt3.txtsent 180 bytes  received 72 bytes  504.00 bytes/sectotal size is 0  speedup is 0.00[root@g_linux01 ~]# ls /tmp/test_dest/1.txt  2.txt  3.txt

--delete 删除原目录中没有的文件

[root@g_linux01 ~]# touch /tmp/test_dest/4.txt[root@g_linux01 ~]# rsync -av --delete /root/soft/ /tmp/test_dest/sending incremental file list./deleting 4.txtsent 63 bytes  received 15 bytes  156.00 bytes/sectotal size is 0  speedup is 0.00

 --exclude 过滤掉log类型文件

[root@g_linux01 soft]# ls 1.log  1.txt  2.txt  3.txt[root@g_linux01 soft]# rsync -av --exclude "*.log" /root/soft/ /tmp/test_dest/sending incremental file list./sent 67 bytes  received 15 bytes  164.00 bytes/sectotal size is 0  speedup is 0.00[root@g_linux01 soft]# ls /tmp/test_dest/1.txt  2.txt  3.txt

 通过ssh同步 ，-e "ssh -p 22" 指定22端口

[root@g_linux01 soft]# rsync -avP -e "ssh -p 22" /root/soft/ 192.168.198.129:/tmp/1_dest/ root@192.168.198.129's password: Permission denied, please try again.root@192.168.198.129's password: sending incremental file listsent 78 bytes  received 12 bytes  6.67 bytes/sectotal size is 0  speedup is 0.00
