                      一、环境
    192.168.10.2上的/data目录下的数据要同步备份到192.168.10.5上/data

二、部署
1、192.168.10.5
    1)、安装rsync并配置
    yum -y install rsync


    vim /etc/xinetd.d/rsync
    service rsync
    {
            disable = no
            flags           = IPv6
            socket_type     = stream
            wait            = no
            user            = root
            server          = /usr/bin/rsync
            server_args     = --daemon
            log_on_failure  += USERID
    }

    vim  /etc/rsync/rsyncd.conf
    uid = root
    gid = root
    use chroot = false
    read only = false
    hosts allow=192.168.10.0/255.255.255.0
    hosts deny=*
    max connections = 8
    pid file = /var/run/rsyncd.pid
    lock file = /var/run/rsync.lock
    log file = /var/log/rsync.log
    transfer logging = yes
    log format = %t %a %m %f %b
    syslog facility = daemon

    timeout = 20
    [data]
    path = /data
    list=no
    comment = backup_data
    auth users = backup
    secrets file = /etc/rsync/rsyncd.passwd
    strict modes = true
    ignore errors = true

    2）、配置密码文件

    echo "backup:backup@123" > /etc/rsync/rsyncd.passwd
    chmod 600 /etc/rsync/rsyncd.passwd

    3）、启动rsync服务

    usr/bin/rsync --daemon --config=/etc/rsync/rsyncd.conf

2、192.168.10.2 配置
    1）、inotify安装
    tar xf inotify-tools-3.14.tar.gz
    cd inotify-tools-3.14
    ./configure --prefix=/usr/local/services/inotify-3.14
    make && make install
    cd /usr/local/services
    ln -sf inotify-3.14 inotify

    2）、监控脚本
    vim inotify.sh
    #!/bin/bash
    host=192.168.10.5  #备份主机ip
    src=/data/        #本地监控目录
    dst=data         #备份主机上rsync的模板
    user=backup      #备份主机的rsync服务的虚拟用户
    rsync_passfile=/usr/local/services/rsyncd.passwd   #本地调用rsync服务的密码文件（只有密码）
    inotify_home=/usr/local/services/inotify    #inotify的安装目录

    if [ ! -e "$src" ] || [ ! -e "${rsync_passfile}" ] \
        || [ ! -e "${inotify_home}/bin/inotifywait" ] || [ ! -e "/usr/bin/rsync" ];then
        echo "Check File and Folder"
    exit 9
    fi
    ${inotify_home}/bin/inotifywait -mrq --timefmt '%y/%m/%d %H:%M' --format '%T %w%f' -e modify,attrib,moved_to,move,create,delete,unmount,close_write,moved_from,delete_self $src \
| while read file
do
    cd $src && rsync -aruz -R --delete ./  --timeout=5  $user@$host::$dst --password-file=${rsync_passfile} >/dev/null 2>&1
    done
    exit 0

    3）、配置密码文件
    echo "backup@123" > /usr/local/services/rsyncd.passwd
    chmod 600 /usr/local/services/rsyncd.passwd

    4)、后台运行脚本
    /usr/local/services/inotify.sh &
