下面来给各位介绍一下linux中mydumper出现libmysqlclient_16 not defined解决办法,希望例子能帮助到各位同学.

昨天在测试mydumper压缩功能（-c）时,出现如下错误:

[root@liufofu backup]# mydumper -h localhost -u root -p tiger -c -o ./liufofu/ -B liufofu

mydumper: relocation error: mydumper: symbol gzopen, version libmysqlclient_16 not defined in file libmysqlclient_r.so.16 with link time reference

定位了下libmysqlclient_16.so在mysql安装目录的lib下有啊,怎么还报错,代码如下:

1. [root@liufofu backup]# ls /usr/local/mysql/lib/ 
2. libdbug.a   libmyisam.a       libmysqlclient.la    libmysqlclient_r.so          
3. libmysqlclient.so         libmysqld.a     libvio.a  plugin 
4. libheap.a   libmyisammrg.a    libmysqlclient_r.a   libmysqlclient_r.so.16      
5. libmysqlclient.so.16      libmystrings.a  libz.a 
6. libmygcc.a  libmysqlclient.a  libmysqlclient_r.la  libmysqlclient_r.so.16.0.0    --phpfensi.com 
7. libmysqlclient.so.16.0.0  libmysys.a      libz.la 

查了下资料应该是系统没有引用这个目录,可以定义下环境变量LD_LIBRARY_PATH,加入/usr/local/mysql/lib这个目录,命令如下.

export LD_LIBRARY_PATH="/usr/local/mysql/lib:$LD_LIBRARY_PATH"

再次执行mydumper压缩功能就没问题了.
