inotifywait+rsync 实时同步脚本

利用 inotifywait 对文件系统事件实时监控, 触发事件调用 rsync 远程同步文件至一台或多台服务器

同步指定目录 (缺点: 每次触发都要扫描整个目录进行文件差异对比, 文件越多越耗时长)

#!/bin/bash

user=root
ip=192.168.0.2
source=/data/
target=/data/
log_path=/var/log/inotifywait.log

inotifywait -mrq ${source} --timefmt '%Y-%m-%d %H:%M:%S' --format '%T %w %f %e' -e create,modify,attrib,move,delete,close_write |
while read files; do
    echo "$files" >> ${log_path}
    INO_EVENT=$(echo $files | awk '{print $5}')
    # 增改查类型
    if [[ $INO_EVENT =~ 'CREATE' ]] || [[ $INO_EVENT =~ 'MODIFY' ]] || [[ $INO_EVENT =~ 'CLOSE_WRITE' ]] || [[ $INO_EVENT =~ 'MOVED_TO' ]] || [[ $INO_EVENT =~ 'ATTRIB' ]]
    then
        rsync -avzc ${source} ${user}@${ip}:${target}
    fi
    # 删除&移出事件
    if [[ $INO_EVENT =~ 'DELETE' ]] || [[ $INO_EVENT =~ 'MOVED_FROM' ]]
    then
        rsync -avz --delete ${source} ${user}@${ip}:${target}
    fi
done

针对性同步, 同步只针对发生改变的文件的目录
ps: 多级目录下, 移动文件或文件夹到上一级目录不会实时同步, 求解决方案

#!/bin/bash

user=root
ip=192.168.0.2
source=/data/
target=/data/
log_path=/var/log/inotifywait.log

inotifywait -mrq ${source} --timefmt '%Y-%m-%d %H:%M:%S' --format '%T %w %f %e' -e create,modify,attrib,move,delete,close_write |
while read files; do
    echo "$files" >> ${log_path}
    INO_EVENT=$(echo $files | awk '{print $5}')
    INO_PATH=$(echo $files | awk '{print $3}')
    # 增改查类型
    if [[ $INO_EVENT =~ 'CREATE' ]] || [[ $INO_EVENT =~ 'MODIFY' ]] || [[ $INO_EVENT =~ 'CLOSE_WRITE' ]] || [[ $INO_EVENT =~ 'MOVED_TO' ]] || [[ $INO_EVENT =~ 'ATTRIB' ]]
    then
        # 同步只针对发生改变的文件的目录
        rsync -avzcR ${INO_PATH} ${user}@${ip}:${target}
    fi
    # 删除&移出事件
    if [[ $INO_EVENT =~ 'DELETE' ]] || [[ $INO_EVENT =~ 'MOVED_FROM' ]]
    then
        rsync -avzR --delete ${INO_PATH} ${user}@${ip}:${target}
    fi
done
