[2018-09-26 05:18:14] error - file: connection_pool.c, line: 130, connect to 10.15.24.109:23000 fail, errno: 113, error info: no route to host
upload file fail, error no: 113, error info: no route to host
原因：是storage那台機器沒有開啟23000埠。
解決：開啟該埠即可。

[2018-01-04 16:37:54] error - file: tracker_proto.c, line: 48, server: 192.168.146.111:22122, response status 2 != 0
tracker_query_storage fail, error no: 2, error info: no such file or directory
經查詢是
錯誤配置：store_path0=/home/fastdfs/storager
正確配置：store_path0=/home/fastdfs/storage
修改配置重啟後上傳成功
原因為storage磁碟空間不足造成的，storage預設的保留磁碟空間大小為reserved_storage_space = 10% # storage server 上保留的空間，保證系統或其他應用需求空間。可通過 storage.conf 配置。
另外還可以通過水平（增加group和storage節點數）和垂直（增加當前storage的磁碟大小）來解決該問題！

第二台tracker日誌
[2018-09-25 21:58:57] error - file: tracker_proto.c, line: 48, server: 10.15.24.107:22122, response status 5 != 0

[2018-09-25 21:58:57] error - file: tracker_mem.c, line: 4297, get sys files from other trackers fail, errno: 2
原因：因為兩邊的tracker裡面的配置檔案不一致
解決：先兩邊都停掉，然後把全的那邊（或者leader）那邊的配置檔案覆蓋到另外乙個tracker，最後重啟就可以了。
當所有fastdfs伺服器關閉後重啟，最開始的時候，防火牆沒有關閉，這時
關閉防火牆之後，上傳仍然報這個錯
關閉防火牆之後
systemctl status firewalld
systemctl stop firewalld
再重啟所有服務，這個時候

然後再上傳檔案，則報
再關閉 防火牆
~]# service iptables stop
redirecting to /bin/systemctl stop iptables.service
[root@localhost ~]# service iptables status
！暈，乙個伺服器開了兩個防火牆！
然後再上傳，就ok了
