【集群架构中的故障集合】_nfs connection reset by peer

3.Connection refused 连接拒绝

检查是否能ping通对应服务器

[12:41 root@backup ~]# rsync -avz /etc 176.16.1.31:/tmp
ssh: connect to host 176.16.1.31 port 22: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: unexplained error (code 255) at io.c(226) [sender=3.1.2]

4.auth failed on module data

data模块认证错误（密码）

原因：
1.密码写错
2.密码文件不存在
3.密码文件权限不对
4.没有创建data这个目录

[root 16:15 @ backup ~]# rsync -avz /etc/hosts [email protected]::data
Password: 
@ERROR: auth failed on module data
rsync error: error starting client-server protocol (code 5) at main.c(1648) [sender=3.1.2]
原因：密码文件权限没有更改为600
[root 16:25 @ backup ~]# ll /etc/rsync.password 
-rw-r--r-- 1 root root 20 May 20 16:05 /etc/rsync.password

解决办法：更改文件权限位600
[root 16:25 @ backup ~]# chmod 600  /etc/rsync.password 
[root 16:25 @ backup ~]# ll /etc/rsync.password 
-rw------- 1 root root 20 May 20 16:05 /etc/rsync.password

5.Unknown module ‘data’ 未知的设备模块

没有权限

[17:45 root@nfs01 ~]# rsync -avz /etc/hostname [email protected]::data --password-file=/etc/rsync.password
@ERROR: Unknown module 'data'
rsync error: error starting client-server protocol (code 5) at main.c(1648) [sender=3.1.2]

服务端查看rsyncd.conf ，准许哪些主机可以访问

hosts allow = 172.16.1.0/24
#hosts deny = 0.0.0.0/32

6.秘密文件

日志中
密码文件问题
查看日志的提示：

019/05/20 16:52:32 [15755] secrets file must be owned by root when running as root (see strict modes)
