Django在云服務器部署打開數據庫失敗

sudo vi /etc/apache2/envvars
將下面2行改成普通能夠登陸系統的賬戶就可以了，比如
export APACHE_RUN_USER=www-data #設置用戶為qunero
export APACHE_RUN_GROUP=www-data #設置組為 www-data

export LANG='en_US.UTF-8'export LC_ALL='en_US.UTF-8' #圖片上傳中文出錯解決方法

重啟服務：sudo service apache2 restart

【1】/etc/apache2/sites-available目錄新建配置文件：Djang2019.conf

【6】權限--https://code.ziqiangxuetang.com/django/django-deploy.html

一般目錄權限設置為 755，文件權限設置為 644

假如項目位置在 /home/tu/XXX （在XXX 下面有一個 manage.py，XXX 是項目名稱）

sudo chmod -R 644 XXX
sudo find zqxt -type d | xargs chmod 755
 
假如上傳目錄為 zqxt/media/uploads 文件夾,進入media文件夾，將 uploads 用戶組改為www-data，并且賦予該組寫權限:
cd media/ # 進入media文件夾
sudo chgrp -R www-data uploads
sudo chmod -R g+w uploads
 
sudo chgrp www-data blog
sudo chmod g+w blog
sudo chgrp www-data blog/db.sqlite3  # 更改為你的數據庫名稱
sudo chmod g+w blog/db.sqlite3
 
python manage.py collectstatic 收集靜態文件
