Rsync+inotify synchronizing data in real time

Environment: CentOS 6.6

Web server: 192.168.2.82

Content Publishing point: 192.168.2.39

One, install rsync on the Web server and configure

1. Install rsync

Yum Install Rsync-y

2. Start Configuring Rsync files

MKDIR/ETC/RSYNCD(default without this file, need to create manually)

Touch/etc/rsyncd/rsyncd.conf

Ln-s/etc/rsyncd/rsyncd.conf/etc/rsyncd.conf

Vi/etc/rsyncd.conf

UID = root GID = root Use chroot = no #limit access to private LANs Hosts allow=192.168.2.0/255.255.255.0 Hosts deny=* Max connections = 5 PID file =/var/run/rsyncd.pid Secrets file =/etc/rsyncd/rsyncd.secrets Log file =/var/log/rsync.log #This would log every file transferred-up to 85,000+ per user, per sync Transfer logging = yes Log format =%t%a%m%f%b Syslog facility = Local3 Timeout = 300 # MODULE OPTIONS [Rsync_test] Path =/rsync_test List=yes WriteOnly = False Read Only = False Ignore errors Auth users = Sandy Comment = Test rsync

Chmod-r 755/var/run

Vi/etc/rsyncd/rsyncd.secrets

sandy:123456

For the security of the password, we set the permission to 600:

Chown Root:root/etc/rsyncd/rsyncd.secrets

chmod 600/etc/rsyncd/rsyncd.secrets

To start the Rsync service:

1. Running the Rsync service with XINETD

CentOS runs the Rsync service by default in xinetd mode. Rsync's xinetd configuration file
In/etc/xinetd.d/rsync. To configure the Rsync service to run with xinetd, you need to execute the following command:

# chkconfig rsync on# service xinetd restart

Administrators can modify the/etc/xinetd.d/rsync configuration file to suit your needs. For example, you can modify the configuration line

Server_args =--daemon

Add the service options for rsync later.

2. Running the rsync service independently

The simplest way to run the Rsync service independently is to execute the following command:

#/usr/bin/rsync--daemon

You can write the above command to the/etc/rc.local file to run the Rsync service each time you start the server. Of course, you can also write a script to start the RYSNC service automatically at boot time.

To start the Rsync service:

/etc/init.d/xinetd restart

See if Port 873 is up

Netstat-an | grep 873

If you see that port 873 is already listening, the rsync service has started

Second, client installation rsync,inotify-tools and configuration

1. Install rsync and configure

Yum Install Rsync-y

The client configures Rsync, creates a password file, synchronizes with this file later and does not need to fill in the password:

touch/etc/rsync_passwd

chmod 600/etc/rsync_passwd

echo "123456" >/etc/rsync_passwd(writes the account password of the server user Sandy to the password file)

2, install Inotify-tools (because the centos6.6 system has built-in inotify, so there is no need to install inotify, see/proc/sys/fs/directory under the INotify folder, if there is already installed, If not, Yum installs)

Yum Install Inotify-tools-y

III. Create a content publishing point file directory and write a live synchronization script file

Mkdir/src

vi/crontab/rsync.sh

#!/bin/bash /usr/bin/inotifywait-mrq--timefmt '%d/%m/%y%h:%m '--format '%T%w%f%e '-e modify,delete,create,attrib/src \ |while Read files Do /USR/BIN/RSYNC-VZRTOPG--delete--progress/src/[email protected]::rsync_test--password-file=/etc/rsync_passwd Done

Iv. execute the script file and verify

1. Execute script file in background

SH +x/crontab/rsync.sh>/crontab/rsync.log &

Boot start:

Echo ' sh +x/crontab/rsync.sh>/crontab/rsync.log & ' >>/etc/rc.local

2. Verification

Client-Created files:

Cd/src

Touch Test.txt

See if the server side automatically has the Test.txt file

CD Rsync_test
