sudo vi /etc/apache2/envvars
将下面2行改成普通能够登陆系统的账户就可以了,比如
export APACHE_RUN_USER=www-data #设置用户为qunero
export APACHE_RUN_GROUP=www-data #设置组为 www-data
重启服务:sudo service apache2 restart
【1】/etc/apache2/sites-available目录新建配置文件:Djang2019.conf
Listen 8008 WSGIPythonPath /home/ubuntu/.VENV/Django2019:/home/ubuntu/.VENV/Django2019/lib/python3.5/site-packages/ WSGIPythonHome /home/ubuntu/.VENV/Django2019 <VirtualHost 0.0.0.0:8008> ServerName 0.0.0.0 ServerAlias 0.0.0.0 ServerAdmin [email protected] DocumentRoot /var/www/html WSGIScriptAlias / /home/ubuntu/workspace/Django2019/Django2019/wsgi.py <Directory /home/ubuntu/workspace/Django2019> Require all granted </Directory> <Directory /home/ubuntu/workspace/Django2019/Django2019> <Files wsgi.py> Require all granted </Files> </Directory> Alias /media/ /home/ubuntu/workspace/Django2019/media/ Alias /static/ /home/ubuntu/workspace/Django2019/static/ <Directory /home/ubuntu/workspace/Django2019/media/> Require all granted </Directory> <Directory /home/ubuntu/workspace/Django2019/static/> Require all granted </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined </VirtualHost>
【2】加载模块
# Python 2
sudo
apt-get
install
libapache2-mod-wsgi
# Python 3
sudo
apt-get
install
libapache2-mod-wsgi-py3
LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so
<Directory />
Options FollowSymLinks
AllowOverride None
#Require all denied
</Directory>
【3】mysqldb(python3)----pip install mysqlclient 或者PyMySQL
项目文件__init__.py
import pymysql
pymysql.install_as_MySQLdb()
【4】wsgi.py
import os import sys from os.path import join,dirname,abspath PROJECT_DIR = dirname(dirname(abspath(__file__))) sys.path.insert(0,PROJECT_DIR) os.environ[‘DJANGO_SETTINGS_MODULE‘] = ‘Django2019.settings‘ from django.core.wsgi import get_wsgi_application application = get_wsgi_application()
【5】setting.py
import os import sys BASE_DIR=os.path.dirname(os.path.dirname(os.path.abspath(__file__))) sys.path.insert(0,os.path.join(BASE_DIR,‘apps‘)) sys.path.insert(1,os.path.join(BASE_DIR,‘extra_apps‘)) ALLOWED_HOSTS = [‘*‘] # Application definition INSTALLED_APPS = [ ‘django.contrib.admin‘, ‘django.contrib.auth‘, ‘django.contrib.contenttypes‘, ‘django.contrib.sessions‘, ‘django.contrib.messages‘, ‘django.contrib.staticfiles‘, ‘xadmin‘, ‘crispy_forms‘, ‘index‘, ] MIDDLEWARE_CLASSES = [ ‘django.middleware.security.SecurityMiddleware‘, ‘django.contrib.sessions.middleware.SessionMiddleware‘, ‘django.middleware.common.CommonMiddleware‘, ‘django.middleware.csrf.CsrfViewMiddleware‘, ‘django.contrib.auth.middleware.AuthenticationMiddleware‘, ‘django.contrib.auth.middleware.SessionAuthenticationMiddleware‘, ‘django.contrib.messages.middleware.MessageMiddleware‘, ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘, ] ROOT_URLCONF = ‘Django2019.urls‘ TEMPLATES = [ { ‘BACKEND‘: ‘django.template.backends.django.DjangoTemplates‘, ‘DIRS‘: [os.path.join(BASE_DIR,‘templates‘)], ‘APP_DIRS‘: True, ‘OPTIONS‘: { ‘context_processors‘: [ ‘django.template.context_processors.debug‘, ‘django.template.context_processors.request‘, ‘django.contrib.auth.context_processors.auth‘, ‘django.contrib.messages.context_processors.messages‘, ‘django.core.context_processors.media‘, ], }, }, ] WSGI_APPLICATION = ‘Django2019.wsgi.application‘ DATABASES = { ‘default‘: { ‘ENGINE‘: ‘django.db.backends.mysql‘, ‘NAME‘: ‘‘, ‘USER‘: ‘root‘, ‘PASSWORD‘: ‘‘, ‘HOST‘: ‘127.0.0.1‘, ‘PORT‘: ‘3306‘, } } AUTH_PASSWORD_VALIDATORS = [ { ‘NAME‘: ‘django.contrib.auth.password_validation.UserAttributeSimilarityValidator‘, }, { ‘NAME‘: ‘django.contrib.auth.password_validation.MinimumLengthValidator‘, }, { ‘NAME‘: ‘django.contrib.auth.password_validation.CommonPasswordValidator‘, }, { ‘NAME‘: ‘django.contrib.auth.password_validation.NumericPasswordValidator‘, }, ] LANGUAGE_CODE = ‘zh-Hans‘ TIME_ZONE = ‘Asia/Shanghai‘ USE_I18N = True USE_L10N = True USE_TZ = False STATIC_URL = ‘/static/‘ STATIC_ROOT = os.path.join(BASE_DIR, ‘static‘) STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), os.path.join(BASE_DIR,"xadmin") ] MEDIA_URL = ‘/media/‘ MEDIA_ROOT = os.path.join(BASE_DIR, ‘media‘)
【6】权限--https://code.ziqiangxuetang.com/django/django-deploy.html
一般目录权限设置为 755,文件权限设置为 644
假如项目位置在 /home/tu/XXX (在XXX 下面有一个 manage.py,XXX 是项目名称)
sudo
chmod
-R 644 XXX
sudo
find
zqxt -
type
d |
xargs
chmod
755
假如上传目录为 zqxt/media/uploads 文件夹,进入media文件夹,将 uploads 用户组改为www-data,并且赋予该组写权限:
cd
media/
# 进入media文件夹
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
# 更改为你的数据库名称
sudo
chmod
g+w blog
/db
.sqlite3
python manage.py collectstatic 收集静态文件
