mkdir /backup/ -p ：创建一个备份目录
echo "yangdi" >/etc/rsync.password ：往密码文件输入密码，需要和rsync客户端相同
chmod 600 /etc/rsync.password
chmod 4755 /usr/bin/rsync
rsync -avz --delete /backup/ [email protected]::backup --password-file=/etc/rsync.password 推送语法:rsync -avz 本地备份目录 服务器端主机名@ip：：备份模块 ----》--delete 无差异备份 删除远端文件（本地备份目录没有的，远端目录不能有）
创建一个专用来下载工具的目录:
mkdir -p /home/yangdi/tools
1.下载inotify-tools-3.14.tar.gz
2.解压tar zxf inotify-tools-3.14.tar.gz
3.cd inotify-tools-3.14
4. 命令 ./configure --prefix=/usr/local/inotify-tools-3.14
5.make&&make install
6.ln -s /usr/local/inotify-tools-3.14/ /usr/local/inotify-tools
7.cd ..
8.cd /usr/local/inotify-tools
inotify_rsync.sh脚本命令 在nfs服务器端，rsync客户端
