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 [email protected]:/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.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 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.txt
sent 63 bytes received 15 bytes 156.00 bytes/sec
total 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/sec
total 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/
