1.安装部署lsync实时同步工具

yum   install  -y    lsyncd

2.编写配置文件

 vim /etc/lsyncd.conf

settings {
 logfile = "/var/log/lsyncd/lsyncd.log",                      #日志文件
 statusFile = "/var/log/lsyncd/lsyncd.status",          #状态信息
 inotifyMode = "CloseWrite",
 maxProcesses = 8,
}
sync {
 default.rsync,
 source = "/data",          #监控NFS目录
 target = "rsync_backup@172.16.1.41::backup",   #实时同步到备份服务器 backup目录
 delete= true,                       #无差异同步
 exclude = { ".*" },
 delay = 1,
rsync = {
 binary = "/usr/bin/rsync",
 archive = true,
 compress = true,
 verbose = true,
 password_file = "/etc/rsync.password",        #NFs密码文件
 _extra = {"--bwlimit=200"}
}
}

3.启动服务

systemctl    start  lsyncd
