在linux上运行程序的时候，发现有这个异常：

Traceback (most recent call last):
  File "rcctestsuite.py", line 13, in <module>
    from validator.db.processor import Processor as DBProcessor
  File "/usr/RAT/src/validator/db/processor.py", line 9, in <module>

  File "build/bdist.linux-x86_64/egg/_mysql.py", line 6, in __bootstrap__
ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory

解决如下：

1. 通过命令   find / -name libmysqlclient_r.so.16，查找libmysqlclient_r.so.16 在什么地方，一般是在/usr/lib64/mysql/下面

2. 做一个链接到/usr/lib64 下： ln -s /usr/lib64/mysql/libmysqlclient_r.so.16 /usr/lib64/libmysqlclient_r.so.16

问题解决。

出现这个问题的原因是mysqldb无法找到libmysqlclient_r.so.16，所以就给它一个。这个文件是mysqldb用来链接到mysql数据库的。
