centos8部署Django

-------------------linux环境设置------------------

#防火墙开放端口
firewall-cmd --list-all
firewall-cmd --zone=public --add-port=9621/tcp --permanent
firewall-cmd --reload

#防火墙删除端口
firewall-cmd --zone=public --remove-port=8888/tcp --permanent
firewall-cmd --reload

#开放http端口
semanage port -a -t http_port_t -p tcp 9621

#关闭http端口
semanage port -d -t http_port_t -p tcp 9621

#查看http端口状态
semanage port -l | grep http

#selinux允许http连接
setsebool -P httpd_can_network_connect 1

#暂时关闭selinux
setenforce 0

#开启selinux
setenforce 1

#按端口查询进程
lsof -i :9621

-------------------Django项目------------------

#新建Django项目
django-admin startproject myweb

#selinux允许访问项目路径
chcon -R -t httpd_sys_content_t '/root/myweb'

#重建表结构
cd /root/myweb
python3 manage.py migrate

#修改settings.py
vim /root/myweb/myweb/settings.py
ALLOWED_HOSTS = ['*']
STATIC_ROOT = '/root/myweb/static'

#测试项目是否正常运行
python3 /root/myweb/manage.py runserver 0.0.0.0:9621

#新建样式目录static
cd /root/myweb
mkdir static
python3 manage.py collectstatic

#若使用mysql，在项目的__init__.py文件添加如下内容
import pymysql
pymysql.install_as_MySQLdb()

#settings文件中修改
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', # 数据库引擎
        'NAME': 'djangodb', # 数据库名
        'USER': 'root', # 账号
        'PASSWORD': 'root', # 密码
        'HOST': '127.0.0.1', # HOST
        'POST': 3306, # 端口
    }
}

#创建管理员
python3 /root/myweb/manage.py createsuperuser


-------------------uwsgi项目------------------

#安装uwsgi
#apt install gcc
yum install gcc
pip3 install uwsgi --upgrade

#启动wsgi
uwsgi --http :9621 --chdir /root/myweb --static-map /static=/root/myweb/static --module myweb.wsgi

#使用uwsgi.ini启动
#uwsgi --ini /root/myweb/uwsgi.ini

#项目目录下新建uwsgi.ini，后续使用WinSCP配置文件
vim /root/myweb/uwsgi.ini

#添加并保存

#http = :9622

#uwsgi任务开机自启
vim /lib/systemd/system/uwsgi.service
#添加并保存
[Unit]
