rsync combined with inotify real-time synchronization configuration

System environment: 192.168.121.128 (source) 192.168.121.129 (Purpose)

192.168.121.129 (Purpose) to install the Rsync service:

Yum install rsync or wget rsync website rsync-3.1.2.tar.gz compiled installation, no parameters required./configure--prefix=/usr/local/rsync

cat /etc/rsyncd.confuid=root//rsync daemon user git=root//// The group use chroot = no // //running the rsync daemon does not use chrootmax connections = 10   //Maximum number of connections limit strict modes = yes//If true, the password file can only be accessed by a user running the rsync server, and no other user can access the file. The default value is true. Pid file = /var/run/rsyncd.pid lock file = /var/run/rsync.lock log  file = /var/log/rsyncd.log [tmp] path = /tmp//directories that need to be synchronized comment =  rsync from 192.168.121.128read only = no write only = no  hosts allow = 192.168.121.128hosts deny = * list = falseuid  = root gid = root auth users = webuser//This user is independent of the system user Secrets file  = /etc/rsync.passwd//defines the authenticated user password file 

cat/etc/rsync.passwd

webuser:password//user and password separated by semicolons

and set the 600 file properties:

chmod 600/etc/rsync.passwd

To start the Rsync service:

/usr/local/rsync/bin/rsync--port=873--address=192.168.121.129--daemon

To do a push test on the 192.168.121.128 (source) Host:

RSYNC-AVH--delete--password-file=/etc/rsync.passwd/tmp/[email protected]::tmp

#注意:/tmp directory default system is already there, if synchronization of other directories, the source host must have, but the destination host may not have, need to manually create, otherwise will error, cannot find the directory, synchronization failed.

Download installation

# wget http://nchc.dl.sourceforge.net/project/inotify-tools/inotify-tools/3.13/inotify-tools-3.13.tar.gz# Tar xzvf inotify-tools-3.14.tar.gz# CD inotify-tools-3.13#./configure--prefix=/usr/local/inotify# make# make install

To create a inotify_rsync.sh script:

cat inotify_rsync.sh#!/bin/sh#function:rysnc 192.168.121.128  to   192.168.121.129if [ ! -f /etc/rsync.passwd ];then         echo  "Password" >/etc/rsync.passwd        /bin/ Chmod 600 /etc/rsync.passwdfilog=/usr/local/inotify/logs/rsync.logsrc= "/tmp/" #注意src如果为/tmp, The TMP directory will be synchronized to the target host, the/tmp/tmp recursive directory appears, so you need to synchronize the files in that directory, need to/end. Host= "192.168.121.129" module= "tmp"/usr/local/inotify/bin/inotifywait -mr --timefmt  '%d/%m/%y  %h:%m '  --format  '%t %w %f '  -e close_write,modify,delete,create,attrib   $SRC  |  while read date time dir file; dofilechange=${dir}$ {FILE}/USR/BIN/RSYNC -AVH --DELETE  --PROGRESS --PASSWORD-FILE=/ETC/RSYNC.PASSWD   $SRC   --exclude-from= "/usr/local/inotify/logs/rules.txt"  [email protected] $host:: $module &echo  "at ${time} on ${date}, file  $FILECHANGE  was  Backed up via rsync " >>  $logdone

#脚本中有delete参数, the test environment can come casually, the production environment is recommended to prohibit the delete parameter.

mkdir/usr/local/inotify/logs//if no directories or files need to be created manually touch/usr/local/inotify/logs/rules.txt

The relevant notes are as follows:

/usr/local/bin/inotifywait-mrq-e Modify,delete,create,attrib ${SRC}

-M is to keep listening

-R is a recursive view directory

-Q is the print out event

-e Close_write,modify,delete,create,attrib refers to the "Listen for create mobile Delete Write permission" event

/USR/BIN/RSYNC-AVH--delete--progress--password-file

-A archive mode

-H Save Hard Connection

-delete deletion of redundant files

--password-file Password file

Today's parameters can be man rsync

To exclude synchronizing a directory, add the--exculde=pattern parameter to rsync, and note that the path is a relative path, specifically to view man rsync.

To exclude the processing of an event listener for a directory, add the--exclude or--excludei parameter to inotifywait to see the man inotifywait.

--exclude-from= "/usr/local/inotify/logs/rules.txt" can match filter files:

If you exclude files that include. SVN:

#cat/usr/local/inotify/logs/rules.txt

-*.svn*

The inotifywait command produces three return values, namely "date, time, file", which are passed as parameters to read, so that the "while read D E F" in the script refines the return value.

Give script permission to execute

#chmod +x inotify_rsync.sh

Run

#sh iotify_rsync.sh &
