1. 安装基础环境
2. 初始化 Python 项目
3. 配置 uwsgi

1、安装基础环境

安装 Nginx 

这里使用 Nginx 作为 web 服务器.

yum install nginx

安装结束执行命令启动 Nginx

systemctl start nginx.service
systemctl enable nginx.service

安装 Python 环境<版本可以自由调换>

安装python3.6

yum install https://centos7.iuscommunity.org/ius-release.rpm -y 
yum install python36u  -y
yum install python36u-pip python36u-devel  -y

为了pip速度更快一些,这里教大家配置一下 pip 的清华镜像

先创建文件夹用来放配置文件

mkdir ~/.config/pip/

接着在文件内添加代码   /.config/pip/pip.conf

[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple

 安装MySQL

这里使用 --------MariaDB

yum install mariadb mariadb-server -y 
systemctl start mariadb.service
systemctl enable mariadb.service

完成后 输入如下命令执行数据库初始化 并设置 root 密码 <密码默认为空>

mysql_secure_installation

2、初始化python项目

first 创建虚拟环境
cd /home/
mkdir django
cd django
python3.6 -m venv venv

next 激活环境
source venv/bin/activate

next 安装 Django 初始化 项目
pip install django
django-admin startproject my
cd my 
python manage.py startapp mine

3、创建App之后 需要修改settings.py的配置

ALLOWED_HOSTS = ['*']

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',

STATIC_URL = '/static/'

4、运行 

python /home/django/my/manage.py runserver 0.0.0.0:80

在无报错的情况下 在浏览器地址栏输入ip地址会出现相对于的界面

5、配置 uwsgi

deactivate
这条命令指的是退出虚拟环境

安装 uwsgi
yum install gcc -y
python3.6 -m pip install uwsgi

安装成功后 执行下行代码 目的是用 uwsgi 来启动 Django
uwsgi --http :80 --chdir /home/django/my --home=/home/django/venv --module my.wsgi

这个时候 浏览器输入 ip 地址 看看是否显示 django 的测试页面

配置 uwsgi
创建一个目录来放置 django 的配置文件,并且在此目录下创建一个文件 uwsgi.ini
mkdir -p /home/django_conf

[uwsgi]
socket = /home/django_conf/my.sock
chdir = /home/django/my
wsgi-file = my/wsgi.py
plugins = python
virtualenv = /home/django/venv/
processes = 2
threads = 4
chmod-socket = 664
chown-socket = nginx:nginx
vacuum = true

6、配置 Nginx

接下来 创建 配置 Nginx 的配置文件

进入nginx/conf.d/my.conf

server {
    listen      80;
    server_name < IP 地址>;
    charset     utf-8;

    client_max_body_size 75M;

    location /media  {
        alias /home/django/my/media;
    }

    location /static {
        alias /home/django/my/static;
    }

    location / {
        uwsgi_pass  unix:///home/django_conf/my.sock;
        include     /etc/nginx/uwsgi_params;
    }
}

完毕后 重启 Nginx

systemctl restart nginx.service

 

7、最后一步 <持久运行 Django>

配置 Supervisord ，确保 django 可以持久运行

安装 Supervisord

yum install python-pip -y
安装完成后，使用 pip 来安装 supervisord，并输出配置文件

python -m pip install supervisor
echo_supervisord_conf > /etc/supervisord.conf
并在配置文件(/etc/supervisord.conf)底部添加如下代码

[program:my]
command=/usr/bin/uwsgi --ini /home/django_conf/uwsgi.ini
directory=/home/django/my
startsecs=0
stopwaitsecs=0
autostart=true
autorestart=true
添加完成后，执行如下命令来启动 supervisord

supervisord -c /etc/supervisord.conf
