WD MyCloud编译的busybox-1.23.2中增加e2fsprogs-1.43.7

参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)配置编译出来的镜像中缺少mkfs.ext3,mkfs.ext4,无法创建GPT分区，我们在此介绍一下如何增加mkfs.ext3,mkfs.ext4的功能。

首先参考Ubuntu 17.10上使用crosstool-ng-1.23.0建立WD MyCloud修复工具编译环境(uClibc)创建我们需要的编译工具。

Building a minimal RootFS with Busybox, GLIBC and DropBear

Ubuntu 17.10上使用crosstool-ng-1.23.0建立WD MyCloud修复工具编译环境(uClibc)

参考更优雅的(不拆硬盘)拯救死翘翘了的WD MyCloud(Ubuntu 17.10)编译出来的Busybox是只有3MB大小的样子，这样编译出来的东西非常基础，功能有限。如果想要增加其他软件的时候，最少改动的情况下，一般都依赖GLIBC,而GLIBC完整编译出来的库接近50MB，而我们修复系统，是一个纯内存文件系统。直接采用GLIBC会非常浪费不多的内存空间。

因此在低内存的系统上采用uClibc，变成一个不错的选择。下面我们讲一下如何通过crosstool-ng-1.23.0构建一个我们需要的编译系统出来。

首先编译crosstool-ng-1.23.0源代码

$ sudo apt-get update
$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf
$ sudo apt-get -y install gperf
$ sudo apt-get -y install bison
$ sudo apt-get -y install flex
$ sudo apt-get -y install texinfo
$ sudo apt-get -y install help2man
$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get -y install autoconf

$ sudo apt-get -y install gperf

$ sudo apt-get -y install bison

$ sudo apt-get -y install flex

$ sudo apt-get -y install texinfo

$ sudo apt-get -y install help2man

$ sudo apt-get -y install ncurses-dev

$ cd ~

$ git clone https://github.com/crosstool-ng/crosstool-ng

$ cd crosstool-ng

$ ./bootstrap

$ ./configure --prefix=`echo ~`/wd_crosstool

$ make

$ make install

如果下载crosstool-ng源代码存在问题，可以从本站下载一份代码拷贝。点击此处下载。

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

$ cd ~

$ mkdir wd_fix_toolchain

$ cd wd_fix_toolchain

$ export PATH=~/wd_crosstool/bin/:$PATH

$ cp ~/crosstool-ng/samples/arm-unknown-linux-uclibcgnueabihf/crosstool.config .config

$ ct-ng oldconfig

#默认一路回车,只是注意，中间选择Linux内核版本的使用，选择使用Linux 3.2 CT_LINUX_V_3_2=y

$ ct-ng build

最终的.config文件，可以参考下面的配置信息，或者简单的拷贝这个文件到编译目录即可

PTP简介

在通信网络中，许多业务的正常运行都要求网络时钟同步，即整个网络各设备之间的时间或频率差保持在合理的误差水平内。网络时钟同步包括以下两个概念：

时间同步：也叫相位同步（Phase synchronization），是指信号之间的频率和相位都保持一致，即信号之间的相位差恒为零。

频率同步（Frequency synchronization）：也叫时钟同步，是指信号之间在频率或相位上保持某种严格的特定关系，信号在其对应的有效瞬间以同一平均速率出现，以保证通信网络中的所有设备都以相同的速率运行，即信号之间保持恒定的相位差。

继续阅读PTP简介

网络时钟同步协议-- NTP, PTP

这篇文章介绍一下两个时钟同步的网络协议：NTP和PTP。
这里不涉及协议的原理和具体实现(想了解的可自行Google)，重点是如何搭建起这两个服务。

1. NTP及PTP简介

NTP(Network Time Protocol)是用于不同计算机之间同步时钟的网络协议。
它的设计目标是使所有的互连的机器之间的时钟与UTC时间只相差若干毫秒。

目前NTP协议已经是有第4版了，如果不需要了解NTP太多细节的话，看看这个wiki页面应该就足够了。需要注意的就是它有clock strata的概念。

PTP(Precision Time Protocol)看名字就知道是一个比NTP更精确的时钟同步协议了，PTP的设计目标是使机器之间的时钟偏差在sub-microsecond范围—这是wiki页面上提到的，有其他的地方说的是偏差若干微秒，本文搭建的环境中测量到的偏差也在微秒级别，没有到sub-microsecond级别。在使用PTP协议时，需要了解的主要概念点就是它的master/slave机制。

接下来我们就介绍我搭建NTP和PTP环境的过程，所用到的操作系统是CentOS6.5，内核版本是3.10。其他软件的版本会在用到时提及。

2. 搭建NTP服务

配置环境：两台服务器，一台做NTP服务器，一台做NTP的客户端。同时这两台机器都未联网。
NTP服务器地址：192.168.0.11
NTP客户端地址：192.168.0.22

A. 在192.168.0.11中启动NTP服务

$ service iptables stop  // 首先把防火墙关了  
$ yum list |grep ntp     // 看下yum源中是否有ntp软件    
$ yum install -y ntp    
$ ntpd --version  
    ntpd 4.2.6p5  
$ vim /etc/ntp.conf      // 修改配置文件  
    restrict 192.168.0.11 mask 255.255.255.0 nomodify nostrap  // 限制作为局域网NTP服务器
    // 下面两句很关键。含义是如果这台NTP服务器的server地址无法访问，  
    // 则将本地时间作为NTP服务时间，这个IP地址也是固定的，不要修改  
    server 127.127.1.0  
    fudge  127.127.1.0 stratum 10   
$ ntpd -p /var/run/ntpd.pid  // 启动ntpd  
$ service ntpd start          // 第二种启动ntpd服务的方法  
// 等待5分钟  
$ ntpstat // 从这条命令应该能看到NTP时钟同步好了，正常的显示结果应该与下面类似  
    synchronised to local net at stratum 11
        time correct to within 11 ms  
        polling server every 64 s

$ service iptables stop // 首先把防火墙关了

$ yum list |grep ntp // 看下yum源中是否有ntp软件

$ yum install -y ntp

$ ntpd --version

ntpd 4.2.6p5

$ vim /etc/ntp.conf // 修改配置文件

restrict 192.168.0.11 mask 255.255.255.0 nomodify nostrap // 限制作为局域网NTP服务器

// 下面两句很关键。含义是如果这台NTP服务器的server地址无法访问，

// 则将本地时间作为NTP服务时间，这个IP地址也是固定的，不要修改

server 127.127.1.0

fudge 127.127.1.0 stratum 10

$ ntpd -p /var/run/ntpd.pid // 启动ntpd

$ service ntpd start // 第二种启动ntpd服务的方法

// 等待5分钟

$ ntpstat // 从这条命令应该能看到NTP时钟同步好了，正常的显示结果应该与下面类似

synchronised to local net at stratum 11

time correct to within 11 ms

polling server every 64 s

B. 在192.168.0.22上启动NTP服务，选择192.168.0.11为NTP服务器

$ service iptables stop
$ yum install -y ntp
$ vim /etc/ntp.conf  // 添加下面这个server地址，把其他的都注释掉  
    server 192.168.0.11  
$ service ntpd start
$ netstat  // 等待若干时间应该就能够显示同步成功了

$ service iptables stop

$ yum install -y ntp

$ vim /etc/ntp.conf // 添加下面这个server地址，把其他的都注释掉

server 192.168.0.11

$ service ntpd start

$ netstat // 等待若干时间应该就能够显示同步成功了

我的这两台实验机器是在同一个Rack的，结果显示差不多同步的偏差在30ms左右。
每个版本的ntpd配置文件可能有少许的差别，不过好在注释都做的不错，所以别的细节就不啰嗦了。

3. 搭建PTP服务

从List of PTP implementations可以看到PTP的实现有很多很多种，可以是硬件实现的，可以是软件实现的也可以是软硬件结合实现的。本文中搭建的PTP服务是基于软件PTPd。如果没有特殊的硬件的话，这算是一种非常方便的方法了。

$ service iptables stop // 关掉防火墙  
$ yum list |grep ptp    // 检查yum源  
$ yum install -y ptpd
$ ptpd2 --version  
    ptpd2 version 2.3.0  
// 弄一个管理脚本，从serverfault找来的 ：）    
// http://serverfault.com/questions/329127/ptp-time-synchronization-on-centos6-rhel
$ vim ptpd.sh  // 将PTPADRGS 改为 PTPD_EXTRA_OPTIONS  
$ chmod +x ptpd.sh 
$ vim /etc/ptpd2.conf  // 修改配置文件  
    ptpengine:preset=masterslave    // 对于master主机，不要选masteronly，具体原因请查看help  
    ptpengine:preset=slaveonly      // 对于slave主机  
    // 其他选项也可以根据需要进行调整，比如log是否开启，是否绑定CPU。这些看配置文件的注释就好了  
$ vim /etc/sysconfig/ptpd2  // 修改启动命令，主要就是指定PTPD的配置文件  
    PTPD_EXTRA_OPTIONS="-c /etc/ptpd2.conf"  
// 现在就可以使用下面三个命令来启动，查看和关闭ptpd服务了  
$ ./ptpd.sh start  
$ ./ptpd.sh status  
$ ./ptpd.sh stop

$ service iptables stop // 关掉防火墙

$ yum list |grep ptp // 检查yum源

$ yum install -y ptpd

$ ptpd2 --version

ptpd2 version 2.3.0

// 弄一个管理脚本，从serverfault找来的：）

// http://serverfault.com/questions/329127/ptp-time-synchronization-on-centos6-rhel

$ vim ptpd.sh // 将PTPADRGS 改为 PTPD_EXTRA_OPTIONS

$ chmod +x ptpd.sh

$ vim /etc/ptpd2.conf // 修改配置文件

ptpengine:preset=masterslave // 对于master主机，不要选masteronly，具体原因请查看help

ptpengine:preset=slaveonly // 对于slave主机

// 其他选项也可以根据需要进行调整，比如log是否开启，是否绑定CPU。这些看配置文件的注释就好了

$ vim /etc/sysconfig/ptpd2 // 修改启动命令，主要就是指定PTPD的配置文件

PTPD_EXTRA_OPTIONS="-c /etc/ptpd2.conf"

// 现在就可以使用下面三个命令来启动，查看和关闭ptpd服务了

$ ./ptpd.sh start

$ ./ptpd.sh status

$ ./ptpd.sh stop

如果遇到任何问题，首先一定要看看help，使用-H选项的话还能看到非常详细的配置（虽然大多我可看不懂，不过不能不看，理解的越多，遇到的问题就会越少）。
如果log里面的信息看不懂，可以把代码下下来，一个grep搞定。

经测试，在我的机器上使用PTPD软件搭建的服务，时钟偏移的平均值能够达到5us左右。这个粒度基本能满足我们的需求了。

Linux中的时钟准确度

本文来自戴尔软件开发高级工程师Stuart Hayes

一个关于计时的问题最近引起了我的关注。有用户在 Dell 服务器上运行 Linux，并且发现时钟时间（Linux 所报告的）每天误差五秒以上，偏差比较明显。

我们首先想到的也许是运行 NTP，定期与真实世界同步操作系统的时钟。

但是这样的误差最初是如何产生的？

在Linux运行时，Linux 系统未使用实时时钟(real time clock - RTC) 硬件来计时。 Linux 通常在启动时从RTC 读取时间，然后从该点开始，Linux 使用另一个时钟来源（系统中的另一个计时器/计数器）来计时。

自第 2.6.18 版起，Linux 的内核就使用 CPU 时间戳计数器 (TSC) 作为首选的时钟来源（假设 TSC 以恒定频率运行，以新款的 Intel 服务器 CPU为例）。但是，尽管读取速度很快且解析度很高，TSC 却不是一个已知的频率。当内核使启动时，它需要使用频率已知的另一个计时器，对其进行校准。这样的校准并非天衣无缝（即使用于校准的计时器也是如此），因此把 TSC 作为时钟来源会造成时间误差。

如果减少时间误差对您非常重要，而非若干微秒的调度延迟，则最好使用频率已知的计时器，如大多数 x86 服务器上提供的 HPET（高精度事件计时器）。借助新内核上的参数"clocksource=hpet"可实现这一目标。 HPET 计时器以已知、固定的频率运行，Linux 内核可直接从计时器读取时间。

话说回来，尽管 HPET 的精度高于 TSC，运行 NTP 以在 Linux 中实现长期的时钟精度始终是很好的想法。
上述讨论仅适用于运行于裸机的 Linux。在虚拟机中的问题略微复杂。
