Rsync服務常見問題匯總
rsync服務端開啟的iptables防火墻
客戶端的錯誤現象：No route to host
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup
rsync: failed to connect to 172.16.1.41: No route to host (113)
rsync error: error in socket IO (code 10) at clientserver.c(124) [sender=3.0.6]
異常問題解決：
關閉rsync服務端的防火墻服務（iptables）
[root@backup mnt]# /etc/init.d/iptables stop
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@backup mnt]# /etc/init.d/iptables status
iptables: Firewall is not running.
rsync客戶端執行rsync命令錯誤：
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::/backup
ERROR: The remote path must start with a module name not a /
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
異常問題解決：
rsync命令語法理解錯誤，::/backup是錯誤的語法，應該為::backup(rsync模塊)
@ERROR: auth failed on module oldboy
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup
Password:
@ERROR: auth failed on module backup
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
異常問題解決：
- 密碼真的輸入錯誤，用戶名真的錯誤
- secrets file = /etc/rsync.password指定的密碼文件和實際密碼文件名稱不一致
- /etc/rsync.password文件權限不是600
- rsync_backup:123456密碼配置文件後面註意不要有空格
- rsync客戶端密碼文件中只輸入密碼信息即可，不要輸入虛擬認證用戶名稱
Unknown module ‘backup‘
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup
@ERROR: Unknown module ‘backup‘
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
異常問題解決：
- /etc/rsyncd.conf配置文件模塊名稱書寫錯誤
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup
Password:

hosts
rsync: mkstemp ".hosts.5z3AOA" (in backup) failed: Permission denied (13)
sent 196 bytes received 27 bytes 63.71 bytes/sec
total size is 349 speedup is 1.57
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1039) [sender=3.0.6]
異常問題解決：
- 共享目錄的屬主和屬組不正確，不是rsync
- 共享目錄的權限不正確，不是755
-
chdir failed
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup
Password:
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
異常問題解決：- 備份存儲目錄沒有建立
- 建立的備份存儲目錄和配置文件定義不一致
[root@backup backup]# /etc/init.d/xinetd restart
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Stopping xinetd: [ OK ]
Starting xinetd: shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
[ OK ]
說明：如果沒有備份存儲目錄，xinetd服務都不能正確啟動
-
invalid uid rsync
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup
Password:
@ERROR: invalid uid rsync
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
異常問題解決：
rsync服務對應rsync虛擬用戶不存在了 - 客戶端已經配置了密碼文件，但免秘鑰登錄方式，依舊需要輸入密碼
password file must not be other-accessible
[root@nfs01 tmp]# rsync -avz /etc/hosts [email protected]::backup --password-file=/etc/rsync.password
password file must not be other-accessible
continuing without password file

sent 26 bytes received 8 bytes 5.23 bytes/sec
total size is 349 speedup is 10.26
異常問題解決：
rsync客戶端的秘鑰文件也必須是600權限
- rsync客戶端連接慢問題
