Hue 安装问题django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: libmysqlclient.so

问题：

[root@master hue-3.11.0]# build/env/bin/hue syncdb

Traceback (most recent call last):
  File "build/env/bin/hue", line 9, in <module>
    load_entry_point('desktop==3.11.0', 'console_scripts', 'hue')()
  File "/sdc3/hue-3.11.0/desktop/core/src/desktop/manage_entry.py", line 65, in entry
    raise e
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: libmysqlclient.so.20: cannot open shared object file: No such file or directory

解决方法：

根据最后提示，应该是找不着一个交libmysqlclient.so.20的文件，于是到mysql安装目录里找到这个文件并且做一个软连接到/usr/lib：
ln -s /usr/local/mysql/lib/libmysqlclient.so.20 /usr/lib/libmysqlclient.so.20
如果是64系统则：
ln -s /usr/local/mysql/lib/libmysqlclient.so.20 /usr/lib64/libmysqlclient.so.20
