Ubuntu下用Rsync+iNotify完成文件单向同步

需求场景：两台ubuntu服务器，从源服务器(代码：src）同步两个目录中内容，到目的服务(代码：dest)的同一目录下。

src 开启rsync

• sudo vi /etc/default/rsync

RSYNC_ENABLE=true

src生成ssh id, 并copy到dest，以打通ssh

• ssh-keygen
• ssh-copy-id -i ~/.ssh/id_rsa.pub dest-user@dest.server

src 安装inotify-tools

• apt-get install inotify-tools

src 监控目录变化+同步脚本1

• sudo vi inotifywait-rsync-dir1.sh

inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e modify,delete,create,moved_to /home/src-user/src-dir1 | while read file
do
rsync -az --progress /home/src-user/src-dir1 dest-user@dest-server:/home/dest-user/dest-dir
echo "${file} was synchronized" >> /home/src-user/rsync_log/rsync.log 2>&1
done

• mkdir /home/src-user/rsync_log

src 监控目录变化+同步脚本2

• sudo vi inotifywait-rsync-dir2.sh

inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e modify,delete,create,moved_to /home/src-user/src-dir2 | while read file
do
rsync -az --progress /home/src-user/src-dir2/ dest-user@dist-server:/home/dest-user/dest-dir/
echo "${file} was synchronized" >> /home/src-user/rsync_log/rsync2.log 2>&1
done

src 加入开机启动

• sudo vi /etc/profile

/bin/bash /home/src-user/inotifywait-rsync-dir1.sh&
/bin/bash /home/src-user/inotifywait-rsync-dir2.sh&

dest 接收端开启rsync

• sudo vi /etc/default/rsync

RSYNC_ENABLE=true
