Rsync synchronizes two servers

Requirement: two servers (a and B) store a large number of images on server a and need to be synchronized to server B at three o'clock every night. Both the source and target directories are/Image

Enable program: rsync

Configuration on server:

1./etc/rsyncd. conf

Uid = nobody

Gid = nobody

Use chroot = No

Max connectionts = 6

Read Only = Yes

Hosts allow = 192.168.95.0/24

PID file =/var/run/rsyncd. PID

Lock file =/var/run/rsyncd. Lock

Log File =/var/log/rsyncd. Log

[Image]

Comment = image

Path =/image/

Ignore errors

List = No

Auth users = root

Secrets file =/etc/rsyncd. passwd

2./etc/rsyncd. passwd

Root: Test

After completing the preceding configuration, run

# Rsync -- daemon

If the system prompts that the rsyncd. passwd file is not found, it indicates that the file is not in the default/etc/path or is not created. You just need to move the file.

Configuration on server B:

/Etc/rsync. passwd

Dongpi2014

Note that the password file on server a and server B is written differently. The password file on server a needs to record the user name, while the password file on server B does not need to record the user name.

Then execute the command

Rsync-ARV -- password-file =/etc/rsyncd. passwd rsync: // [email protected]/test/image/

In this way, synchronization starts.

Note:

If the following error is reported:

@ Error: Unknown module 'xxx'

Rsync error: Error starting client-server protocol (Code 5) at main. C (1503) [runner ER = 3.0.6]

ThisAn error indicates that the Password File Permission is incorrect. The normal password file permission should be 600

The -- password-file option may only be used when accessing an rsync daemon.

This error indicates that the server has not executed the rsync -- daemon command (the service has not been started)

@ Error: AUTH failed on module XXXXX

This error indicates that there is a problem with the username and password in server a and server B, which may be caused by the format of username and password in server B.

In addition to the above methods, you can also use the automated notebook CT script to complete

#! /Usr/bin/CT

Set timeout 3000

Spawn rsync-avcz -- delete [email protected]:/image // Image

Reset CT "Password :"

Send "dongpi2014 \ r"

CT "] *"

Exit
