rsync 備份報錯總結

1）密碼檔案不能被其他人訪問

[root@web01 ~]# rsync -avz ./dir [email protected]::backup --password-file=/etc/rsyncd.passwd
ERROR: password file must not be other-accessible
rsync error: syntax or usage error (code 1) at authenticate.c(196) [sender=3.1.2]

解決：給密碼檔案賦予許可權（rsync在上傳檔案的時候是以當前使用者的許可權執行檔案的相關操作）
[root@web01 ~]# chmod 600 /etc/rsyncd.passwd 
 

2）上傳失敗 上傳的檔案不存在

[root@web01 ~]# rsync -avz ./dir [email protected]::backup --password-file=/etc/rsyncd.passwd
sending incremental file list
rsync: link_stat "/root/dir" failed: No such file or directory (2)

sent 22 bytes  received 20 bytes  84.00 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(1179) [sender=3.1.2]

解決：
檢查上傳的檔案是否存在 檔名是否寫錯
 

3） 連結超時 連結地址失敗

[root@web01 ~]# rsync -avz ./dir15 [email protected]::backup --password-file=/etc/rsyncd.passwd
rsync: failed to connect to 172.16.1.41 (172.16.1.41): Connection timed out (110)
rsync error: error in socket IO (code 10) at clientserver.c(125) [sender=3.1.2]

# 解決 首先ping下網址否能通
地址是否寫對



 

4）連結失敗 沒有路由訪問到主機

[root@web01 ~]# rsync -avz ./dir15 [email protected]::backup --password-file=/etc/rsyncd.passwd
rsync: failed to connect to 172.16.1.41 (172.16.1.41): No route to host (113)
rsync error: error in socket IO (code 10) at clientserver.c(125) [sender=3.1.2]


# 解決 由於服務端的防火牆沒有關和安全策略組 導致客服端連結不上路由訪問服務端
[root@backup ~]# vim /etc/selinux/config    SELINUX enforcing 改成 SELINUX disabled
[root@backup ~]# systemctl stop firewalld
[root@backup ~]# source /etc/selinux/config
