rsync + inotify 实现单向数据同步

单向实时同步,主节点做的同步,备节点实时同步,但备节点的有变更的话主节点不会变

主节点:

10.0.0.10    controller

备节点:

10.0.0.31    compute1

在compute1上面,安装rsync,配置rsync.conf

在controller上面,安装rsync+inotify,启动rsync.sh这个脚本

---

1.配置compute1节点,

yum -y install rsync

vim /etc/rsyncd.conf

在写入下面的内容

---

uid = root

gid = root

read only = no

use chroot = no

max connections = 512

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log

log format = %t %a %m %f %b

[rsync]

path = /home/

list = no

ignore errors

auth users = rsync_user

hosts allow = 10.0.0.10

hosts deny = *

secrets file = /etc/rsyncd.pwd

---

vim /etc/rsyncd.pwd

写入下面的内容

---

rsync_user:rsync@2010

---

chmod 600 /etc/rsyncd.conf

chmod 600 /etc/rsyncd.pwd

rsync --daemon

echo "rsync --daemon" >> /etc/rc.local

2.配置controller节点,

yum -y install inotify-tools rsync

vim /usr/local/sbin/rsync.sh

写入下面的内容

---

#!/bin/bash
src=/home/rsync
[email protected]::rsync
inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src |while read files
do
rsync -vzrtopg --delete --progress --password-file=/etc/rsyncd.pwd $src $dst  >/dev/null 2>&1
done

---

chmod 700 /usr/local/sbin/rsync.sh

sh /usr/local/sbin/rsync.sh &

echo "/usr/local/sbin/rsync.sh" >> /etc/rc.local
