rsync file sync backup from Linux to Linux

rsync file sync backup from Linux to Linux

First, the environment

Server (server side) that needs to back up files: 192.168.1.201 (RHEL 5)

Server (client) receiving backup files: 192.168.1.202 (CENTOS 5)

Second, installation configuration

1. Server-side configuration

A, using the system default installation of Rsync edit/etc/rsyncd.conf file, if not a new one.

Vi/etc/rsyncd.conf

#[globale]

Strict modes= Yes #check passwd file

port= 873 #default Port

Logfile=/var/log/rsyncd.log

Pidfile=/var/run/rsyncd.pid

Max Connections= 4

#[modules]

[Testlink] #备份模块

uid= Root

gid= Root

Path=/usr/local/apache/htdocs/testlink/upload_area #要备份的目录

Read Only= No

Host allow= *

Auth users= wwyhy

Secrets file=/ETC/RSYNCD.SCRT

[Bugfree] #备份模块

uid= Root

gid= Root

Path=/usr/local/apache/htdocs/bugfree/bugfile #要备份的目录

Read Only= No

Host allow= *

Auth users= wwyhy

Secrets file=/ETC/RSYNCD.SCRT

[Redmine] #备份模块

uid= Root

gid= Root

Path=/usr/local/redmine-0.8.1/files #要备份的目录

Read Only= No

Host allow= *

Auth users= wwyhy

Secrets file=/ETC/RSYNCD.SCRT

B. Add a password file

Vi/etc/rsyncd.scrt

The contents are as follows:

wwyhy:123456 # (Set yourself)

C, change the permissions of 600

chmod 600/ETC/RSYNCD.SCRT

D, start the service (if you have a firewall, allow port 873 to pass)

Rsync--daemon--config=/etc/rsyncd.conf &

2. Configure the Client

Client I compiled my own installation of the rsync-3.0.3.tar.gz

A, Installation:

TAR-ZXVF rsync-3.0.3.tar.gz

CD rsync-3.0.3

./configure

Make

Make install

B. Add a password file

VI/ETC/RSYNCD.SCRT (no new)

The contents are as follows:

wwyhy:123456 (file is the same as client file content)

C, change the file permissions to 600

chmod 600/ETC/RSYNCD.SCRT

Third, start the backup

The backup instructions can be viewed on the client via the man rsync command

We use the script to automate the backup.

Column: Rsync-avz--password-file= password file path [email protected] Host IP required for backup:: module name in Backup

Path to receive backup files

Build a script file in/root
