rsync文件同步工具介紹

rsync工具能夠用來同步文件，好比a目錄到b目錄，a機器到b機器，（屢次同步，能夠只同步變更的文件）

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

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

root@可省略，默認是當前登陸用戶

經常使用選項

[root@g_linux01 ~]# rsync -av /root/soft/ /tmp/test_dest/
sending incremental file list
./
1.txt
2.txt
3.txt

sent 180 bytes  received 72 bytes  504.00 bytes/sec
total size is 0  speedup is 0.00
[root@g_linux01 ~]# ls /tmp/test_dest/
1.txt  2.txt  3.txt

--delete 刪除原目錄中沒有的文件

[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.txt

sent 63 bytes  received 15 bytes  156.00 bytes/sec
total size is 0  speedup is 0.00

 --exclude 過濾掉log類型文件

[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/sec
total size is 0  speedup is 0.00
[root@g_linux01 soft]# ls /tmp/test_dest/
1.txt  2.txt  3.txt

 經過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/
