#做实施同步的时候，主机和备机之间必须已经做好了ssh免密登录
$ vim /etc/lsyncd.conf
settings {
    logfile = "/var/log/lsyncd/lsyncd.log",
    statusFile = "/var/log/lsyncd/lsyncd.status"
}
sync {
    default.rsyncssh,
    source = "/aaa/aaa/aaa", --源目录
    host = "xx.xx.xx.xx", --目的主机
    targetdir = "/bbb/bbb/bbb", --远程目录
    delete = true,
    delay = 1,
    rsync = {
        binary = "/usr/bin/rsync",
        archive = true, --归档
        compress = true, --压缩
        verbose = true, 
        owner = true,   --属主
        perms = true,   --权限
        _extra = {"--bwlimit=2000"},//限制文件同步速度,2mb/s
        },
    ssh = {
        port = 22
    }
}
#重启服务
$ systemctl restart lsyncd
#开机启动
$ systemctl enalbe lsyncd
#查看同步状态
$ systemctl status lsyncd
