Django 安装

• 安装python3：apt install python3
• 安装pip3: apt install python3-pip
• 安装django: pip3 install Django
• 检查是否安装成功

root@server_1:/var/HttpTestProject# django-admin.py --version
2.0.4

MySQL 安装

• 安装MySQL Server： apt install mysql-server
• 安装MySQL Client： apt install mysql-client
• 启动MySQL Server： /etc/init.d/mysql start

DB配置 -- Local MySQL

• MySQL创建项目DBCREATE DATABASE IF NOT EXISTS test COLLATE utf8_general_ci;
• 更改项目 settings.py 中的 DB 配置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'test',
        'USER': 'root',
        'PASSWORD': 'root',
        'HOST': '127.0.0.1',
        'PORT': '3306'
    }
}

• 安装MySQLdb python module: apt-get install libmysqld-dev
• 检查是否安装成功

>>> import MySQLdb
>>>

• 如果没有安装成功且提示ImportError: No module named 'MySQLdb', 安装pip3 install MySQL-python
• 如果安装MySQL-python失败，且提示ImportError: No module named 'ConfigParser', 安装：

pip3 install mysqlclient
apt install python3-dev libmysqlclient-dev

• MySQLdb安装成功：

>>> import MySQLdb
>>>

• 检查 Django 与 MySQL 是否绑定成功

• 在项目 HttpTestProject 目录下添加 uwsgi 目录

cd /var/HttpTestProject/
mkdir uwsgi

• 在 uwsgi 目录下添加 uwsgi.ini 文件

# uwsig使用配置文件启动
[uwsgi]

# 项目目录
chdir=/var/HttpTestProject/

# 指定项目的application
module=HttpTestProject.wsgi:application

# 指定sock的文件路径       
socket=/var/HttpTestProject/uwsgi/HttpTestProject.sock

# 进程个数       
workers=4
pidfile=/var/run/HttpTestProject.pid

# 指定IP端口       
http=127.0.0.1:8001

# 指定静态文件
static-map=/static=/var/HttpTestProject/static

# 启动uwsgi的用户名和用户组
uid=root
gid=root

# 启用主进程
master=true

# 自动移除unix Socket和pid文件当服务停止的时候
vacuum=true

# 序列化接受的内容，如果可能的话
thunder-lock=true

# 启用线程
enable-threads=true

# 设置自中断时间
harakiri=30

# 设置缓冲
post-buffering=4096

# 设置日志目录
daemonize=/var/log/HttpTestProject_uwsgi.log

• 启动 uwsgi：uwsgi --ini uwsgi.ini

                # 导入一个Nginx模块他是用来和uWSGI进行通讯的
                include uwsgi_params;   

                # 设置连接uWSGI超时时间
                uwsgi_connect_timeout 30;  

                # 指定uwsgi的sock文件所有动态请求就会直接丢给他
                uwsgi_pass unix:/var/HttpTestProject/uwsgi/HttpTestProject.sock; 
        }

        # 指定静态文件路径
        location /static/ {
