背景

Mac的TimeMachine要求储存设备实现AFP，即Apple Filing Protocol，才能给Mac进行备份。所以自建一个AFP Server做备份。

目标

  • 在Ubuntu上搭建AFP实现使用Mac TimeMachine备份

过程

先尝试一下用apt安装

1

$ sudo apt install netatalk
# 安装完成以后查看一下版本号
$ afpd -v
afpd 2.2.5 - Apple Filing Protocol (AFP) daemon of Netatalk

只有2.2.5，而官网上最新的是3.1.10，所以果断卸载去从源码安装最新版。

依照官方教程安装必要的依赖

$ sudo apt install build-essential libevent-dev libssl-dev libgcrypt20-dev libkrb5-dev \
libpam0g-dev libwrap0-dev libdb-dev libtdb-dev libmysqlclient-dev avahi-daemon \
libavahi-client-dev libacl1-dev libldap2-dev libcrack2-dev systemtap-sdt-dev libdbus-1-dev \
libdbus-glib-1-dev libglib2.0-dev libio-socket-inet6-perl tracker libtracker-sparql-1.0-dev \
libtracker-miner-1.0-dev

一共23个包，官方居然没有写成一条命令，看得眼睛痛。

然后下载源码，这里选择netatalk-3.1.10.tar.bz2。

# 解压缩
$ tar xvf netatalk-3.1.10.tar.bz2

$ cd netatalk-3.1.10

# 列出帮助，看看如何配置，列在最后，方便以后复习
$ ./configure --help

配置之前需要查看一下刚刚安装的tracker的版本，1.0无误。

$ pkg-config --list-all | grep tracker
tracker-sparql-1.0 tracker-sparql - Tracker : A library to perform SPARQL queries and updates in the Tracker Store
tracker-miner-1.0 tracker-miner - A library to develop tracker data miners

开始配置，程序会自动检测，但是下面这些是不会的，所以需要自己根据情况指定，

$ ./configure \
    --with-init-style=debian-systemd \ #使用系统的初始化配置，16.04使用这个就行
    --without-libevent \ #不使用bundle，不知道什么用，虽然刚刚好像下了这个包，既然是官网的先做个看
    --without-tdb \ #同上
    --with-cracklib \
    --enable-krbV-uam \
    --with-pam-confdir=/etc/pam.d \
    --with-dbus-daemon=/usr/bin/dbus-daemon \
    --with-dbus-sysconf-dir=/etc/dbus-1/system.d \
    --with-tracker-pkgconfig-version=1.0

如果上面的输出没有什么错误的，那就可以开始安装了

# 这一步我有多个warning，只要不是错误应该就行了
$ make

# 输出和上一步居然差不多，还以为有错
$ sudo make install

afpd has been compiled with support for these features:

    AFP versions: 2.2 3.0 3.1 3.2 3.3 3.4
    CNID backends: dbd last tdb mysql

    afp.conf: /usr/local/etc/afp.conf

    UAM search path: /usr/local/lib/netatalk//
    Server messages path: /usr/local/var/netatalk/msg/

这样就没有问题了。

然后按照上面的AFP配置路径设置一下AFP Server：

1
$ sudo vi /usr/local/etc/afp.conf

这里给出我自己的配置

[Global]
; Global server settings
hosts allow = 192.168.1.0/24

[My Time Machine Volume]
path = /mnt/timemachine/storage
time machine = yes
vol size limit = 170000

hosts allow是可以访问的列表，我这样配置就只有接入了我的路由器的设备可以访问，上面中括号的里面的My Time Machine Volume其实就是之后会显示出来的文件名，用time machine = yes来告诉服务器，这个path需要启用time machine，vol size limit可以用来限制使用多少空间，然后重启一下服务

1
$ sudo service avahi-daemon restart

接下来就可以看到Mac里面会有一个以自己的服务器命名的设备了，连接以后即可，结果如下

连接成功
