2)安装mysql-python

sudo apt-get install libmysqlclient-dev
sudo apt-get install python-dev
sudo pip install mysql-python

若不安装，CTFd中运行serve.py会报错（ImportError: No module named MySQLdb）

3)安装gunicorn

sudo pip install gunicorn

安装CTFd
下载&安装&运行CTFd
sudo git clone https://github.com/isislab/CTFd.git
cd CTFd
sudo ./prepare.sh
sudo python serve.py

配置数据库
修改CTFd目录下的config.py

HOST = "47.76.**.**"
SQLALCHEMY_DATABASE_URI = 'mysql://root:<mysql_passwd>@localhost/CTFd?charset=utf8'

然后进入数据库

mysql -u root -p

新建一个数据库

CREATE DATABASE CTFd;

退出数据库返回CTFd目录运行一下serve.py，ctrl+c退出再进入数据库

use CTFd;
