How to Deploy to Ubuntu 18.04 Server [2021.6.20]

1 - 设置服务器

设置新host和user

// 更新Ubuntu
apt-get update && apt-get upgrade 

// 设置 hostname
hostnamectl set-hostname django-server
hostname 

// 在 `nano /etc/hosts` 添加 （中间用tab）
103.     django-server 

// 新建服务器用户并赋予sudo
adduser faradawn
adduser faradawn sudo
exit

重新连接服务器

// 新建
mkdir -p ~/.ssh 

// 苹果电脑
ssh-keygen -b 4096
scp ~/.ssh/id_rsa.pub faradawn@103.000.0.0:~/.ssh/authorized_keys

设置权限

sudo chmod 700 ~/.ssh/
sudo chmod 600 ~/.ssh/*
sudo nano /etc/ssh/sshd_config (设置 PermitRootLogin no 和 #PasswordAuthentications no，未做)
sudo systemctl restart sshd

防火墙

sudo apt-get install ufw
sudo ufw default allow outgoing
sudo ufw default deny incoming
sudo ufw allow ssh
sudo ufw allow 8000
sudo ufw enable
sudo ufw status
// 之后再allow http

2 - 上传Django项目

拷贝到服务器

scp -r django-api faradawn@103:~/
sudo apt-get install python3-pip
sudo apt-get install python3-venv

配置虚拟环境

python3 -m venv django-api/django-env
source django-env/bin/activate
pip install -r requirements.txt
// 出问题就用
sudo apt install python3-dev libpq-dev
pip3 install psycopg2

设置django static

// 在 settings.py
ALLOWED_HOSTS = ['103.']

// static 在MEIDA root 之上
STATIC_ROOT = os.path.join(DASE_DIR, 'static')

// 输入
// python manage.py collectstatic

安装Postgres

// 下载
sudo apt install postgresql postgresql-contrib

// 新建数据库
sudo -u postgres psql
postgres=# create database myapi_db;
postgres=# create user faradawn with encrypted password 'xxx';
postgres=# grant all privileges on database myapi_db to faradawn;
postgres=# ALTER DATABASE myapi_db OWNER TO faradawn;

// 倒入数据
psql -U faradawn letter_db < letter.db

// 开启服务器
source django-api/django-env/bin/activate
python manage.py runserver 0.0.0.0:8000

3 - 安装Apache

下载 apache2

// 下载apache
sudo apt-get install apache2
sudo apt-get install libapache2-mod-wsgi-py3
cd /etc/apache2/sites-available
sudo cp 000-default.conf django-api.conf
sudo nano django-api.conf

在 django-api.conf 里黏贴

Alias /static /home/faradawn/django-api/static
<Directory /home/faradawn/django-api/static>
    Require all granted
</Directory>

Alias /media /home/faradawn/django-api/media
<Directory /home/faradawn/django-api/media>
    Require all granted
</Directory>

<Directory /home/faradawn/django-api/mysite>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

WSGIScriptAlias / /home/faradawn/django-api/mysite/wsgi.py

WSGIDaemonProcess django-process python-path=/home/faradawn/django-api python-home=/home/faradawn/django-api/django-env/

WSGIProcessGroup django-process

WSGIPassAuthorization On

回到home

// 启动配置文件
sudo a2ensite django-api 
sudo a2dissite 000-default.conf

// 给予Apache文件权限
sudo chown -R :www-data /etc/postgresql/10/main (equivalent to db.sqlite)
sudo chmod 664 /etc/postgresql/10/main
sudo chown :www-data django-api/

sudo chown -R :www-data django-api/media (未做)
sudo chmod -R 775 django-api/media (未做)

配置SECRET_KEY

// 在 Home
sudo touch /etc/api-config.json
sudo vi settings
sudo nano /etc/api-config.json

{
        "SECRET_KEY": "django-insecure-rkjkqx"
}

// 在项目 settings.py
import json
with open('/etc/api-config.json') as config_file:
    config = json.load(config_file)

SECRET_KEY = config['SECRET_KEY']
DEBUG = False

最后让防火墙允许http

sudo ufw delete allow 8000
sudo ufw allow http/tcp
sudo service apache2 restart

4 - 用 Git 部署到 VPS

新建gitrepo

mkdir project.git

问题集合

  • 尝试 runserver 如果 port 8000 already in use (只是宝塔问题)
  • 无法写入数据库 (sudo chmod 775 django-api/)
  • Django: no credential found (添加 sudo nano /etc/apache2/sites-avaible/django-api.conf ，然后重启 sudo service apache2 restart

祝成功！
