在linux上搭建用于mac时间机器备份的server

mac的时间机器备份可以支持外接硬盘和samba，用samba结合ceph存储时间机器的数据比较方便。samba需要4.8以上版本，实际用docker安装samba4.8，虽然mac可以挂载，但时间机器不能识别，fedora29上的samba4.9可以支持时间机器备份。

一、搭建samba用于备份

1、安装fedora29

2、安装samba

dnf install samba

3、配置samba，开启支持时间机器的配置

编辑smb.conf

[global]        workgroup = SAMBA        security = user        passdb backend = tdbsam        printing = cups        printcap name = cups        load printers = yes        cups options = raw[macbackup]     comment = mac backup     path = /opt/share/macbackup     browseable = yes     public = no     writeable = yes     valid users = macbackup    create mask = 0600    directory mask = 0700    # 以下配置用于支持时间机器    spotlight = yes    vfs objects = catia fruit streams_xattr    fruit:aapl = yes    fruit:time machine = yes

4、重启samba，添加用户

systemctl enable smbsystemctl start smbsmbpasswd -a macbackup

5、用finder连接smb，打开时间机器，就可以看到挂载的volume

二、搭建netatalk用于备份

由于samba需要4.9的版本，centos7上无法用fedora29的samba源代码编译成rpm，在centos7可以用netatalk为时间机器提供备份

1、构建netatalkrpm包

yum install mockuseradd -m mock -g mocksu  - mockwget http://www003.upp.so-net.ne.jp/hat/files/netatalk-3.1.11-1.4.fc29.src.rpm mock -r /etc/mock/epel-7-x86_64.cfg --rebuild netatalk-3.1.11-1.4.fc29.src.rpm

编译好的rpm在/var/lib/mock/epel-7-x86_64/result中

2、安装配置netatalk

yum localinstall netatalk-3.1.11-1.4.el7.x86_64.rpmcat /etc/netatalk/afp.conf;; Netatalk 3.x configuration file;[Global]; Global server settings; [Homes]; basedir regex = /home; [My AFP Volume]; path = /path/to/volume; [My Time Machine Volume]; path = /path/to/backup; time machine = yes[Time Machine Voume]    path = /opt/share/macbackup     time machine = yes    spotlight = novalid users = macbackup

3、创建登录用户，netatalk登录时，使用linux用户

# useradd -d /opt/share/macbackup  -s /sbin/nologin macbackup# 不必创建home目录useradd -M   -s /sbin/nologin macbackuppasswd macbackup

4、在finder中连接，afp://youre_ip，以用户macbackup登录，打开时间机器，可以看到挂载的volume

5、有些文章说要安装avahi，avahi不安装也可以，netatalk的端口为548
