This experiment realizes one-way synchronization and non-two-way synchronization.

Experimental environment: two virtual machines, I have two CentOS5.5

Software deployment:

Server side (IP:192.168.1.104): rsync-3.0.9.tar.gz and inotify-tools-3.14.tar.gz

Client (IP:192.168.1.108): rsync-3.0.9.tar.gz

Steps:

[root@CentOS5smb] # ls

Inotify-tools-3.14.tar.gz rsync-3.0.9.tar.gz

[root@CentOS5smb] # tar zxvf rsync-3.0.9.tar.gz-C / gwq/20130616/

[root@CentOS5smb] # cd / gwq/20130616/rsync-3.0.9

[root@CentOS5rsync-3.0.9] #. / configure-prefix=/usr/local/rsync

[root@CentOS5rsync-3.0.9] # make

[root@CentOS5rsync-3.0.9] # make install

[root@CentOS5rsync-3.0.9] # cd / usr/local/rsync/

[root@CentOS5rsync] # echo "rsync-pwd" > / usr/local/rsync/rsync.passwd

/ rsync-pwd is a password and can be customized

[root@CentOS5rsync] # chmod 600 rsync.passwd

/ / to avoid unnecessary errors, please change the permission to 600

Rsync on this server has been installed, but it hasn't been configured yet. Let's install inotify first, and then configure rsync later.

[root@CentOS5smb] # ls

Inotify-tools-3.14.tar.gz rsync-3.0.9.tar.gz

[root@CentOS5smb] # tar zxvf inotify-tools-3.14.tar.gz-C / gwq/20130616/

[root@CentOS5smb] # cd / gwq/20130616/inotify/

[root@CentOS5inotify-tools-3.14] #. / configure-prefix=/usr/local/inotify

[root@CentOS5inotify-tools-3.14] # make

[root@CentOS5inotify-tools-3.14] # make install

Now configure rsync

Create a new rsync.sh file, and here I create a new rsync.sh under / tmp

[root@CentOS5tmp] # vi rsync.sh

# / bin/bash

Host=192.168.1.108 / / client IP address

Src=/tmp / directories to be monitored by the server in real time

Des=web / certified module name, which needs to be consistent with the client

User=webuser / / establish the authenticated user in the password file

/ usr/local/inotify/bin/inotifywait-mrq--timefmt'%d/%m/%y%H:%M'--format'%T%w%f%e'-emodify,delete,create,attrib$src\

| | whilereadfiles |

Do

/ usr/bin/rsync-vzrtopg--delete--progress--password-file=/usr/local/rsync/rsync.passwd$src$user@$host::$des

Echo "${files} wasrsynced" > > / tmp/rsync.log2 > & 1

Done

[root@CentOS5tmp] # chmod 764 rsync.sh

[root@CentOS5tmp] # sh rsync.sh& / run the script in the background

[root@CentOS5tmp] # echo "/ tmp/rsync.sh" > > / etc/rc.local/rsync.sh / the script is added to the boot entry

[root@CentOS5tmp] # touch / etc/rsyncd.conf / create an empty rsyncd.conf file under etc

Now that the server has been configured, let's configure the client

Client configuration, download and install rsync

[root@CentOS5gwq] # ls

Rsync-3.0.9.tar.gz

[root@CentOS5gwq] # tar zxvf rsync-3.0.9.tar.gz

[root@CentOS5gwq] # ls

Rsync-3.0.9 rsync-3.0.9.tar.gz

[root@CentOS5gwq] # cd rsync-3.0.9

[root@CentOS5rsync-3.0.9] #. / configure-prefix=/usr/local/rsync

[root@CentOS5rsync-3.0.9] # make

[root@CentOS5rsync-3.0.9] # make install

[root@CentOS5rsync-3.0.9] # echo "webuser:rsync-pwd" > / usr/local/rsync/rsync.passwd

/ / the password file established by the server contains only the password and no user name, while the password file established in the client has both user name and password

[root@CentOS5rsync-3.0.9] # cd / usr/local/rsync

[root@CentOS5rsync] # chmod 600 rsync.passwd

Create a new rsync profile

[root@CentOS5rsync] # pwd

/ usr/local/rsync

[root@CentOS5rsync] # vi rsync.conf

Secretsfile=/usr/local/rsync/rsync.passwd

[root@CentOS5rsync] # / usr/local/rsync/bin/rsync-daemon

/ / start the rsync service of the server and client

Create new files and directories under the server tmp directory, and the client will automatically synchronize

Manual synchronization command format:

[root@CentOS5rsync] # / usr/bin/rsync-vzrtopg--delete-progress-- password-file=/usr/local/rsy

Nc/rsync.passwd/tmp/webuser@192.168.1.108::web

Automatic synchronization command format:

Sh rsync.sh&

You can schedule tasks to synchronize rsync for a period of time in the following format:

* / 1****/usr/bin/rsync-Rav-- delete--password-file=/usr/local/rsync/rsync.passwdwebuser@192.168.2.173::web/tmp

In this way, it will be synchronized every minute. The effect of my task plan in this format is to synchronize the files and directories specified by the client, not the server, which means that you create a new file on the server, which will disappear automatically after a minute, because there is no such file in the client, but if you create a new file in the client, it will be synchronized to the server one minute later (cron plan needs to be operated on the server. The operation on the client is unresponsive)

Using sh rsync.sh& synchronizes the server's
