Inotify+rsync multiple Dir-sync

System: centos6.5

IP:10.19.21.241 is synchronized to the end

10.19.21.242 Synchronous End

I. Configuring Rsync (synchronous side)

1. Install rsync

# yum Install-y rsync

2. Write rsync configuration

# vi/etc/rsyncd.confuid = Rootgid = RootUse chroot = Nomax connections = 0 #最大连接数不限制log file =/var/log/rsyncd.logpi d file =/var/run/rsyncd.pidlock File =/var/run/rsyncd.lockhosts allow = * #允许所有主机 [Test1]path =/home/test1/comment = Rsync from Everyoneread only = Nolist = Noauth users = rsyncusersecrets File =/etc/rsync.pas[test2]path =/home/test2/c Omment = rsync from Everyoneread only = Nolist = Noauth users = rsyncusersecrets file =/etc/rsync.pas

3. Create a password file

# echo "rsyncuser:123456" >/etc/rsync.pas

4. Change Password file permissions

# chmod 600/etc/rsync.pas

5. Start the service

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

Two. Configuring the INotify (synced side)

1. Install rsync

# yum Install-y rsync

2. Installing INotify

# wget http://nchc.dl.sourceforge.net/project/inotify-tools/inotify-tools/3.13/inotify-tools-3.13.tar.gz# Tar zxf inotify-tools-3.13.tar.gz# CD inotify-tools-3.13#./configure--preifx=/usr/local/inotify# make && make Install

3. Create a inotify_rsync_dirs.sh script

#!/bin/bashinotify_rsync_fun  () {    dir= ' echo $1 | awk -f ","   ' {print $1} '     ip= ' echo $1 | awk -f ', '   ' {print  $ '     des= ' echo $1 | awk -f ', '   ' {print $3} '      user= ' echo $1 | awk -f ', '   ' {print $4} '     /usr/ local/inotify/bin/inotifywait -mr --timefmt  '%d/%m/%y %h:%m '  --format  '%T % W %f '  -e modify,delete,create,attrib ${dir} |while read date time  DIR FILE        do                 FILECHAGE=${DIR}${FILE}                 /usr/bin/rsync -av -- progress --delete  --password-file=/etc/rsync.pas ${dir} ${user}@${ip}::${des} && echo  "At ${ time} on ${date}, file  $FILECHAGE  was backed up via rsync "  >> /var/log/rsyncd.log        done}count=2# localdir, host,rsync_module,user of rsync_module,sync1= "/home/test1/,10.19.21.242,test1,rsyncuser" sync2= "/Home /test2/,10.19.21.242,test2,rsyncuser "############################################################# #maini = 0while [ ${i} -lt ${count} ]do    i= ' expr ${i} + 1 '     tmp= ' sync ' $i     eval  sync=\$ $tmp      inotify_rsync_fun  "$sync"  &done

The relevant comments are as follows:

/usr/local/inotify/bin/inotifywait-mr

-M is to keep listening

-R is a recursive view directory

-Q is the print out event

-e modify,delete,create,attrib refers to "Listen create move Delete Write permission"

/usr/bin/rsync-av--progress--delete--password-file=/etc/rsync.pas

-A archive mode

-delete Delete redundant files

--password-file Password file

4. Add a password file

# echo 123456 >/etc/rsync.pas

5. Add Permissions

# chmod +x inotify_rsync_dirs.sh

6. Execution of commands

#./inotify_rsync_dirs.sh

Three. Testing
