五、Rsync案例排错
5.1 案例1
[root@linuxidc ming]# rsync -avz /ming/ tang@172.16.1.41::luo/ --password-file=/etc/tang
@ERROR: auth failed on module luo
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
[root@linuxidc luo]# tail -3 /var/log/rsyncd.log
2016/12/02 19:46:18 [3601] secrets file must not be other-accessible (see strict modes option)
2016/12/02 19:46:18 [3601] continuing without secrets file
2016/12/02 19:46:18 [3601] auth failed on module luo from unknown (172.16.1.31): missing secret for user "tang"
报错的原因是服务器端的/etc/tang的权限问题没有设置为600，我们查看一下。
[root@linuxidc luo]# ls -ld /etc/tang
-rwxr-xr-x 1 root root 13 12月 2 19:34 /etc/tang
权限改为600就可以了
5.2 案例2
[root@linuxidc ~]# rsync -avz /ming/ tang@172.16.1.41::luo/ --password-file=/etc/tang
@ERROR: auth failed on module luo
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
查看日志
[root@linuxidc luo]# tail -3 /var/log/rsyncd.log
2016/12/02 19:52:12 [3614] name lookup failed for 172.16.1.31: Name or service not known
2016/12/02 19:52:12 [3614] connect from UNKNOWN (172.16.1.31)
2016/12/02 19:52:12 [3614] auth failed on module luo from unknown (172.16.1.31): password mismatch
password mismatch，密码错误，客户端和服务器端的密码不一致导致的问题。
【注意】有的客户端和服务器端密码看起来一样，实际里面有空格，也能报错，注意一下
5.3 案例3
[root@linuxidc ~]# rsync -avz /backup/ rsync://rsync_backup@172.16.1.41/backup/ --password-file=/etc/rsync.password
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
原因：服务端的backup目录不存在
5.4 案例4
[root@linuxidc ~]# rsync -avz /backup/ rsync://rsync_backup@172.16.1.41/backup/ --password-file=/etc/rsync.password
sending incremental file list
./
rsync: failed to set times on "." (in backup): Operation not permitted (1)
1
sent 4325 bytes received 1911 bytes 12472.00 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(1039) [sender=3.0.6]
原因：服务端backup的属组和属主问题
