The configuration of rsync under Linux for folder synchronization

The configuration of rsync under Linux for folder synchronization

http://blog.csdn.net/cymm_liu/article/details/31347531

Objective: to [88]_a of the host /data/home/web sync to [27]_b of the host /data/home/qy Catalogue

B Host as rsync Server

# Check if the system has rsync packages installed
[Email protected] home]# Rpm-qa |greprsync
rsync-2.6.9
if not, go to yum or apt-get install or go to the website server

1. custom boot mode, configured as follows:

new or configured rsyncd.conf
[Email protected] etc]# vim rsyncd.conf

UID = www

GID = www

Use chroot = no

Port = 873

Max connections = 10

PID file =/var/run/rsyncd.pid

#log file =/var/log/rsyncd.log

Hosts allow = 110.163.200.119

Hosts deny = *

## The above section is a global configuration, the following module can have multiple

[web]

Path =/data/home/qy/

Ignore errors = yes

Read Only = no

Write only = no

List = no

Auth users = www

Secrets file =/etc/rsync.pass

# # above configuration instructions:

#port can not add, because the default is 873 port, can be changed to another port

#auth Users What account is used for synchronization verification, this user and /etc/password It 's no matter.

#secrets file holds rsync plaintext password files, for security purposes, this file permissions modified to :wei:huashuo_rsync, the middle of the space is not separated by a colon.

# "[QY]" is a custom module name, here is equivalent to a delimiter, if you want to synchronize multiple folders here to differentiate , English name is called module, note the directory permissions

Configuring Auto-start vi/etc/rc.d/rc.local
/usr/bin/rsync--daemon--config/etc/rsyncd.conf

system default boot mode:

AddRsyncService Scripts
Vi/etc/xinetd.d/rsync
#will beDisable=yesinsteadNo

Service rsync
{
Disable = no
Socket_type =stream
Wait =no
User =root
Server =/usr/bin/rsync
Server_args =--daemon
Log_on_failure +=userid
}
RHELinstallation is defaultrsync,Edit/etc/xinetd.d/rsyncafter useService xinetd Restartto start.

Ahost as client, configure

2. web.rsync.sh File script:

#!/bin/sh

# # Defining conditions

Hosts= "110.144.80.16"

Src= "/data/home/web/"

Exclude_files= "/usr/mybin/qy.exclude.ini"

Module=web

User=www

# # to synchronize the local src directory to the path of the Rsync server module,the INI file specifies where filtering is not synchronized, the "Web" module is ysync Name of the server-side definition

/usr/local/inotify/bin/inotifywait-mrq--timefmt '%y-%m-%d%h:%m:%s '--format '%T%w%f%e ' \

-E Close_write,delete,create,attrib $src | While read files

Do

For I in $hosts

Do

/USR/BIN/RSYNC-VZRTOPG--exclude-from= $exclude _files--delete--progress--password-file=/etc/client.rsync.pass $ src [email protected] $i:: $module

Exitcode=$?

if [$EXITCODE! = 0]; Then

echo "${files} rsync Error:" $EXITCODE >>/var/log/inotify.log 2>&1

Break

Fi

Done

Done

Only the rsync server password is in the #/etc/client.rsync.pass file .

Create a file that filters out of sync

Vi/usr/mybin/qy.exclude.ini

*.zip

*.gz

*.tar.gz

*.sql

*.tgz

*.rar

log/*

i/tmp/*

blog/

memcached/

system/conf_main.php

Start the automatic synchronization script

nohup/root/web.rsync.sh >>/dev/null 2>&1 &
