rsync错误
rsync error：No route to host
rsync服務端開啟的iptables防火墻 [root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::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: Setting chains to policy ACCEPT: filter [ OK ] iptables: Flushing firewall rules: [ OK ] iptables: Unloading modules: [ OK ] [root@backup mnt]# /etc/init.d/iptables status iptables: Firewall is not running.
ERROR: The remote path must start with a module name not a /
rsync客戶端執行rsync命令錯誤：
客戶端的錯誤現象：
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::/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 backup
@ERROR: auth failed on module oldboy
客戶端的錯誤現象：
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::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：
1. 密碼真的輸入錯誤，用戶名真的錯誤
2. secrets file = /etc/rsync.password指定的密碼文件和實際密碼文件名稱不一致
3. /etc/rsync.password文件權限不是600
4. rsync_backup:123456密碼配置文件后面注意不要有空格
5. 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
@ERROR: Unknown module 'backup'
Unknown module 'backup' [root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::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：
1. /etc/rsyncd.conf配置文件模塊名稱書寫錯誤
2.配置文件中網段限制不對

異常問題解決：
1. 備份存儲目錄沒有建立
2. 建立的備份存儲目錄和配置文件定義不一致

說明：如果沒有備份存儲目錄，xinetd服務都不能正確啟動

異常問題解決：
rsync服務對應rsync虛擬用戶不存在了
continuing without password file
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

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
