FastDFS_V5.05版本升級說明

gg9654

為了大家避免，在升級FastDFS是碰到問題，分享一下，我升級版本的經(jīng)驗。

一、問題概述

最近從5.02 升級到V5.05 出現(xiàn)了一些編譯上的問題，比如函數(shù)未定義之類的。系統(tǒng)采用的Centos 6.4 X64, 具體編譯錯誤 如下

1. trunk_mgr/trunk_mem.o: In function `storage_trunk_free_node':
   
2. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:639: undefined reference to `fast_mblock_free'
   
3. trunk_mgr/trunk_mem.o: In function `trunk_add_free_block':
   
4. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1192: undefined reference to `fast_mblock_alloc'
   
5. trunk_mgr/trunk_mem.o: In function `trunk_add_space_by_node':

13. trunk_mgr/trunk_mem.o: In function `trunk_delete_space':
    
14. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1345: undefined reference to `fast_mblock_free'
    
15. trunk_mgr/trunk_mem.o: In function `trunk_split':
    
16. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1406: undefined reference to `fast_mblock_alloc'
    
17. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1422: undefined reference to `fast_mblock_free'
    
18. trunk_mgr/trunk_mem.o: In function `trunk_free_space':
    
19. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:1150: undefined reference to `fast_mblock_alloc'
    
20. trunk_mgr/trunk_mem.o: In function `storage_trunk_destroy_ex':
    
21. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:304: undefined reference to `fast_mblock_destroy'
    
22. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:305: undefined reference to `fast_mblock_destroy'
    
23. trunk_mgr/trunk_mem.o: In function `storage_trunk_restore':
    
24. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:760: undefined reference to `fast_mblock_alloc'
    
25. trunk_mgr/trunk_mem.o: In function `storage_trunk_init':
    
26. /usr/local/src/FastDFS/storage/trunk_mgr/trunk_mem.c:200: undefined reference to `fast_mblock_init_ex'

復(fù)制代碼

二、問題原因

這是由于老的libfastcommon無法支持新版的FastDFS。如果只是單純編譯新的libfastcommon，老的lib庫不刪除的話，會導(dǎo)致編譯時鏈接到老的庫，就是出現(xiàn)許多函數(shù)未定義，網(wǎng)上很多說要卸載FastDFS系統(tǒng)在安裝，其實不用，只要將老的libfastcommon庫刪除就可以了。

三、解決方案

下面給出 具體指令，自測通過 僅供參考

1. rm -rf /usr/local/lib/libfdfs*
   
2. rm -rf /usr/local/lib/libfast*
   
3. rm -rf /usr/lib64/libfastcommon.*
   
4. rm -rf /usr/lib64/libfdfsclient.*
   
5. rm -rf /usr/lib/libf*
   
6. 
   
7. vim make.sh  
   
8. TARGET_PREFIX=$DESTDIR/usr/  改成 TARGET_PREFIX=$DESTDIR/usr/local
   
9. 
   
10. 
    
11. ln -s /usr/lib64/libfastcommon.so /usr/local/lib/libfastcommon.so
    
12. ln -s /usr/lib64/libfastcommon.so /usr/lib/libfastcommon.so
    
13. ln -s /usr/local/lib64/libfdfsclient.so /usr/local/lib/libfdfsclient.so
    
14. ln -s /usr/local/lib64/libfdfsclient.so /usr/lib/libfdfsclient.so

復(fù)制代碼

編輯 make.sh是由于 老的FastDFS安裝在/usr/local/bin下，新版改成了/usr/bin 為了兼容老版 特此更改

謝謝，這么快5.05版就出來了。

    5.05 的版本對應(yīng)的java_client 應(yīng)該使用那個？？
