Rsync+inotify-tool of multiple Web server code synchronization

Rsync+inotify

Enterprise Web site synchronization methods have multiple, can be used to mount the shared hard disk, but can also be used Rsync+inotify-tool way.

Rsync: Responsible for pushing data to the server.

INotify: Responsible for monitoring code or file changes in the client, triggering the push.

Environment Description:

centos-6.5

A Server-side (192.168.10.2) B client (192.168.10.1)

650) this.width=650; "title=" QQ picture 20141015125455.jpg "Src=" http://s3.51cto.com/wyfs02/M01/4C/77/wKiom1Q9_kKiUdu_ Aablwnntq0w567.jpg "alt=" Wkiom1q9_kkiudu_aablwnntq0w567.jpg "/>

2: Configure file synchronization

The rsync service is installed first, and rsync plus inotify-tools is installed on master node A .

Yum-y Install Rsync

Download and install Inotify-tools

wget https://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz

Tar zxvf inotify-tools-3.14.tar.gz

CD Inotify-tools

./configure && make && make install

Do link ln-sv/usr/local/lib/libinotify*/usr/lib/ If it is a system ln-sv/usr/local/ lib/libinotify*/usr/lib64

Otherwise the launch will report the error "/usr/local/bin/inotifywait:error while loading shared libraries:libinotifytools.so.0"

Configuring rsync on host B

Establishing a rsyncd.conf configuration file

Cat/etc/rsyncd.conf

uid = Root # Specifies the uid that the daemon should have when the module transfers files

gid = Root # Specifies the GID that the daemon should have when the module transfers files

Use chroot = no

hosts allow =192.168.1 0.1 192.168.10.2 # allows any host connection

Max connections = number of client maximum Connections , default 0 ( No Limit )

PID file =/var/run/rsyncd.pid # where is the ID of the running process written to

Lock file =/var/run/rsync.lock #lock record file

Log file =/var/log/rsyncd.log # logging Files

[web] # Here is the name of the authentication module, which needs to be specified on the client side

Path =/ # You need to make a backup directory . ( preferably the current directory of the backup directory, because he will back up the entire folder, and repeat the long.) )

Comment = dwg file

Ignore errors # can ignore some unrelated IO Errors

Read Only = no #no client can upload file , yes Read only

List = False

Auth users = User1 # Authenticated user name, if not this line, indicates is anonymous

Secrets file =/etc/server.pas # Specifies the location of authentication password files

Establish the Authentication password file

Cat/etc/server.pas

User1 : 123456

chmod 600/etc/server.pas

Start service rsync--daemon

Then build the password file on host A

Cat/etc/server.pas

123456

chmod 600/etc/server.pas

Then create a monitoring script on the primary contact A

Monitor the modify,delete,create,attrib of the /usr/local/nginx/html/ directory and push it directly to B Server up

cat/root/rsync.sh

#!/bin/bash

src=/ Web

/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 --password-file=/etc/server.pas  $src   user1 @192.168.1 0.1 ::               #A watch yourself change. to b push, if you add arguments to the back, such as   192.168.10.1::web /web test push yourself.

Done

Watching

-M is to keep listening

-R is a recursive view directory

-Q is the print out event

--TIMEFMT is the output format for the specified time

--format Specify details of file changes

-e create,move,delete,modify,attrib refers to the " listen for Create mobile delete Write permission " event

）

And then run

Nohup./rsync.sh &
