哦，记一篇rsync的烦事

就是两台服务器同步数据，一上午都没事，就这个目录同步不了，

首先发，服务肯定是没问题了，那么就是权限问题。然后将源文件及所属目录的属主、属组、权限改为777和同步的用户，仍旧报错，内容如下：

rsync -avP Shost::user/opt/hahaha/ .

receiving incremental file list
rsync: change_dir "/~" (in user) failed: No such file or directory (2)

sent 8 bytes  received 94 bytes  204.00 bytes/sec
total size is 0  speedup is 0.00
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1650) [Receiver=3.1.2]

反向复制报错

rsync -avP /opt/hahaha/ Dhost::user/opt/hahaha/

sending incremental file list
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(759) [sender=3.0.6]

最终解决办法: 

将opt目录授权给同步用户
