OB2D 架設rsync備份伺服器(方便2台電腦傳資料用)

1. 設定 rsync server: (假設這台主機為163.26.174.5)
   
   規劃建立備份目錄區(/bk)
   
   mkdir /bk
    　
   
2. 
   
   設定: /etc/xinetd.d/rsync
   
   vi /etc/xinetd.d/rsync
   

   # 若要停用rsync,只要把default:off前的#拿掉即可
   # default: off
   # description: The rsync server is a good addition to am ftp server, as it \
   # allows crc checksumming etc.
   service rsync
   {
   disable = no
   socket_type = stream
   wait = no
   user = root
   server = /usr/bin/rsync
   server_args = --daemon
   log_on_failure += USERID
   }

   
   　
3. 設定: /etc/rsyncd.conf
   
   vi /etc/rsyncd.conf
   
   

   [mch1]
   path = /bk
   auth users = user
   uid = root
   gid = root
   secrets file = /etc/rsyncd.secrets
   read only = no

   存檔
    　
4. 設定: 密碼檔
   vi /etc/rsyncd.secrets
   user:12345678
   chown root.root rsyncd.secrets
   chmod 600 rsyncd.secrets
   service xinetd restart
    　 　 　
5. 設定 rsync client　電腦 (假設這台主機 IP 為 : 163.26.174.1)
   vi /root/rsyncd.secrets
   
   12345678
   
   chmod 600 /root/rsyncd.secrets
   　
6. 執行
   
   /usr/bin/rsync -rvlHpogDtS --password-file=/root/rsyncd.secrets /home user@163.26.174.5::mch1
   
   若出現傳輸目錄檔案的畫面, 即表示測試成功.
    　
7. 安全性:(視需要設定)
   vi /etc/rc.local
   
   加入
   
   iptables -A INPUT -p tcp -s ! 163.26.174.1 --dport 873 -j DROP
   
   執行/etc/rc.local
