我正在使用python3.6，mysql-community-server-8.0.11-1和fedora28，我正在尝试为我的django应用程序设置mysql，但是我收到了一个错误

(myblogvenv) [saurabhkumar@localhost myblog]$ python manage.py runserver
Performing system checks...
Segmentation fault (core dumped)

如果我使用默认的sqlite3数据库，服务器就会出现。
当我跑的时候 django-admin dbshell 我得到以下错误：

(myblogvenv) [saurabhkumar@localhost myblog]$ django-admin dbshell

这是我的项目结构：

(myblogvenv) [saurabhkumar@localhost myblog]$ ls
db.sqlite3  manage.py  myblogvenv  mysite
(myblogvenv) [saurabhkumar@localhost myblog]$ cd mysite
(myblogvenv) [saurabhkumar@localhost mysite]$ ls
__init__.py  __pycache__  settings.py  urls.py  wsgi.py

settings.py中的数据库部分

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'blog',
        'USER': 'bloguser',
        'PASSWORD': 'Blog#user1',
        'HOST': '/var/lib/mysql',
        'PORT': '3306',
    }
}

使用以下软件包

(myblogvenv) [saurabhkumar@localhost mysite]$ pip list
Package     Version
----------- -------
Django      2.0.6  
mysqlclient 1.3.12

pytz        2018.4

任何关于如何调试/修复问题的指针都将帮助我继续。
