lsyncd简介

Lysncd 实际上是lua语言封装了 inotify 和 rsync 工具，采用了 Linux 内核（2.6.13 及以后）里的 inotify 触发机制，然后通过rsync去差异同步，达到实时的效果。我认为它最令人称道的特性是，完美解决了 `inotify + rsync`海量文件同步带来的文件频繁发送文件列表的问题 —— 通过时间延迟或累计触发事件次数实现。另外，它的配置方式很简单，lua本身就是一种配置语言，可读性非常强。lsyncd也有多种工作模式可以选择，本地目录cp，本地目录rsync，远程目录rsyncssh。
实现简单高效的本地目录同步备份（网络存储挂载也当作本地目录），一个命令搞定。

3.安装

[root@nfs01 ~]# yum install lsyncd -y

4.创建配置文件

[root@nfs01 ~]# cat /etc/lsyncd.conf
settings {
  logfile = "/var/log/lsyncd/lsyncd.log",
  statusFile = "/var/log/lsyncd/lsyncd.status",
  inotifyMode = "CloseWrite",
  maxProcesses = 8,
}
sync {
  default.rsync,
  source = "/data",
  target = "rsync_backup@172.16.1.41::data",
  delete = true,
  exclude = { ".*" },
  delay = 1,
  rsync = {
    binary = "/usr/bin/rsync",
    archive = true,
    compress = true,
    verbose = true,
    password_file = "/etc/rsync.passwd",
    _extra = {"--bwlimit=200"}
  }
}

sync {
  default.rsync,
  source = "/backup",
  target = "rsync_backup@172.16.1.41::backup",
  delete = true,
  exclude = { ".*" },
  delay = 1,
  rsync = {
    binary = "/usr/bin/rsync",
    archive = true,
    compress = true,
    verbose = true,
    password_file = "/etc/rsync.passwd",
    _extra = {"--bwlimit=200"}
  }
}
