今天安装MySQLmtop的时候报错，发现没有安装python的MySQLdb模块，手动运行报如下错：
[root@test1 mysqlmtop]# python
Python 2.6.6 (r266:84292, Aug 18 2016, 15:13:37)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-17)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
Traceback (most recent call last):
File "

ImportError: libmysqlclient.so.18: cannot open shared object file: No such file or directory
>>> quit
Use quit() or Ctrl-D (i.e. EOF) to exit

解决方法:
root@test1 mysqlmtop]# ln -s /usr/local/mysql/lib/libmysqlclient.so.18 /usr/lib64/
[root@test1 mysqlmtop]#
再次运行测试：
[root@test1 mysqlmtop]# python
