rsync服務(wù)端開(kāi)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(wèn)題解決：

   關(guān)閉rsync服務(wù)端的防火墻服務(wù)（iptables）

   [root@backup mnt]# /etc/init.d/iptables stop

 rsync客戶端執(zhí)行rsync命令錯(cuò)誤：

   客戶端的錯(cuò)誤現(xiàn)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(wèn)題解決：

   rsync命令語(yǔ)法理解錯(cuò)誤，::/backup是錯(cuò)誤的語(yǔ)法，應(yīng)該為::backup(rsync模塊)

rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]

   異常問(wèn)題解決：

   1. 密碼真的輸入錯(cuò)誤，用戶名真的錯(cuò)誤

   2. secrets file = /etc/rsync.password指定的密碼文件和實(shí)際密碼文件名稱不一致

   3. /etc/rsync.password文件權(quán)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(rèn)證用戶名稱

   異常問(wèn)題解決：

   1. 共享目錄的屬主和屬組不正確，不是rsync

   2. 共享目錄的權(quán)限不正確，不是755

    異常問(wèn)題解決：

    1. 備份存儲(chǔ)目錄沒(méi)有建立

    2. 建立的備份存儲(chǔ)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

說(shuō)明：如果沒(méi)有備份存儲(chǔ)目錄，xinetd服務(wù)都不能正確啟動(dòng)
