rsyncd用来同步2台机器上的操作来保证数据的一致，inotify用来检测系统的变化，利用rsync+inotify来实现实时同步
s:192.168.1.234 路径：/usr/local/nginx-1.6.3/html/home/paixian/root
c:192.168.1.136 路径：/data/paixian/root
1.服务器上的操作
yum install rsync xinetd -y ///下载软件
vi /etc/rsyncd.conf ///手动创建rsyncd配置文件
#Global Settings
uid = nobody
gid = nobody
use chroot = yes
max connections = 10
timeout = 300
strict modes = yes
pid file = /var/run/rsync/rsyncd.pid
#lock file = /var/run/rsync/rsyncd.lock
log file = /var/log/rsync/rsyncd.log
[data]
#path =/usr/local/nginx-1.6.3/html/home/paixian/root
path =/usr/local/nginx-1.6.3/html/home/paixian/root
ignore errors = yes
read only = no
write only = no
hosts allow = 192.168.1.0/24
hosts deny = *
list = false
uid = root
gid = root
auth users = min
secrets file = /etc/rsyncd.passwd
vi /etc/rsyncd.passwd ///创建密码文件
min:min
chmod 600 /rsyncd.passwd
service xinetd start ///启动xinetd服务（包括rsyncd服务）
2.客户端配置
先测试rysnc
echo "passwd" > /etc/rsync.passwd ///创建密码文件
[root@min root]# rsync --list-only--password-file=/etc/rsyncd.passwd [email protected]::data
drwxrwxrwx 4096 2015/09/10 17:46:58 .

drwxrwxrwx 4096 2015/09/10 14:50:41 web
利用inotify监控系统的变化
wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
mv inotify-tools-3.14.tar.gz /usr/local
cd /usr/local
tar xf inotify-tools-3.14.tar.gz
mv inotify-3.14 inotify
./configure
make&&make install
写脚本实现同步
[root@min root]# cat/usr/local/inotify/backup.sh
inotifywait -mrq --timefmt'%Y/%m/%d-%H:%M:%S' --format '%T %w %f %e' -e modify,attrib,move,create,delete/data/paixian/root|while read files
do
rsync -vzrtopg --delete --progress--password-file=/etc/rsyncd.passwd /data/paixian/root/ [email protected]::data&& echo "${files} was rsynced" >>/tmp/rsync.log2>&1
echo"--------------------------------------------------------"
done
运行脚本
bash /usr/local/inotify/backup.sh &
[root@min root]# ps -ef |grep backup
root 1670 1 0 16:16 ? 00:00:00 bash/usr/local/inotify/backup.sh
root 1672 1670 0 16:16 ? 00:00:00 bash /usr/local/inotify/backup.sh
root 1782 1729 0 18:32 pts/1 00:00:00 grep backup
