1.做好ssh 互信
2.安装inotify
查看是否支持inotify ls -lsart /proc/sys/fs/inotify
yum install -y inotify-tools --enablerepo=epel
检测是否成功安装 inotifywait -h
3.配置同步脚本
#!/bin/bash
host=10.xxx
src=/data/test/
log_file=/var/log/rsync_client.log
inotify_fun(){
/usr/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e modify,delete,create,attrib $src | while read files
do
/usr/bin/rsync -auvrtzopgP --delete --progress ${src} ${host}:${src}
done
}
inotify_fun >> ${log_file} 2>&1 &4.脚本开机启动echo "/scripts/rsync.sh" >> /etc/rc.local
两台机器都安装inotify+rsync,修改下脚本里的host地址即可
