Rsync+inotify configuration of automatic backup server

Rsync+inotify configuration of automatic backup server

1 Backing up the server ip:192.168.1.106

Client ip:192.168.1.107

2.

#yum-y install rsync xinetd gcc gcc-c++

Install both of these services, as well as the C + + compiler (if not in advance, to avoid the compiler when compiling binary files)

3. Create a rsyncd.conf on the server side (192.168.1.106)/etc

#service iptables Stop shuts down the firewall with SELinux

#vi/etc/selinux/config will selinux=disabled

#vi/etc/rsyncd.conf

UID = nobody

GID = Nobody

Max connections = 200

Timeout = 600

Use chroot = no

Hosts allow = *

PID File=/var/run/rsyncd.pid

#syslog facility = Local7

Log File=/var/log/rsyncd.log

#rsync con**

#The ' Standard ' things

[Backup]

Path =/backup//Create a directory under the root of the server to back up the files of the client

Ignore errors//Ignore some errors

Read Only = no

List = no

Auth users = test//authenticated user

Secrets file =/etc/rsyncd.secrets Authenticated user's username and password location

4. Compile/etc/xinetd.d/rsync on the server side (192.168.1.106)

#vi/etc/xinetd.d/rsync

Service rsync

{

Disable = no//Change the original yes to no OK

Flags = IPV6

Socket_type = Stream

wait = no

user = root

Server =/usr/bin/rsync

Server_args =--daemon

Log_on_failure + = USERID

}

3 h Create authenticated user and password files on the server side

#vi/etc/rsyncd.secrets

Test:test

: Wq

Save exit

6. Start the Rsync service

#service xinetd Restart

#/usr/bin/rsync--daemon--config=/etc/rsyncd.conf

7. Note The issue of permissions causes the client to be unable to connect

#chmod 777/backup

#chmod 600/etc/rsyncd.secrets

Password file must be changed to 600 permissions, or the client will be connected when the error

Configuration of the client (192.168.1.107)

#yum install gcc gcc-c++ rsync xinetd

#service xinetd Restart

#service iptables Stop

#netstat-TNL |grep 873

1. Vi/etc/rsyncd.secrets

testpasswd

: Wq

Save exit

2. Modify Permissions

#chmod 600/etc/rsyncd.secrets

3. On the client

#rsync-VZRTOPG--password-file=/etc/rsyncd.secrets/aaa [email protected]::backup

Where AAA is the directory to be backed up locally to the server

This is for manual synchronization, the command is also very cumbersome to write it to a shell corner of the book through the crontab call for automatic synchronization

But there is one more efficient way to do this is to say the rsync+inotify combination

Http://inotify-tools.sourceforge.net download the appropriate installation package

# TAR-ZXVF Inotify-tools-3.14.tar.gz

#cd inotify-tools-3.14

#./configure && make && make install

Write a shell corner book after the installation is complete

#vi rsync.sh

#!/bin/bash

Src=/aaa

Des=backup

ip=192.168.1.106

/usr/local/bin/inotifywait-mrq--timefmt '%d/%m/%y%h:%m '--format '%T%w%f '-E modify,delete,create,attrib $src | While read file

Do

RSYNC-VZRTOPG--delete--progress $src [email protected] $ip:: $des--password-file=/etc/rsyncd.secrets &&

echo "$src was rsynced"

Done

: Wq

#nohup sh/root/rsync.sh & Note the middle space

This ensures that when you modify the files inside the client's/aaa, it is immediately updated to the server side to achieve fast data consistency.
