Dash官网只有付费的部署方式❌ 我的简单理解,uWSGI去运行dash app并且与nginx通讯;nginx处理浏览器传来的请求并把需求给uWSGI
Python enviroment
代码语言:Python
复制
mkdir bioquest
vi ~/bioquest/dash.yaml
micromamba env create -n dash --file dash.yaml
micromamba activate dash
代码语言:YAML
复制
# vi ~/bioquest/dash.yaml
channels:
- conda-forge
dependencies:
- python=3.10
- dash-bootstrap-components
- numpy
- pandas
- plotly
- dash-bootstrap-templates
- scikit-learn
- matplotlib
- seaborn
- uwsgi
directory
app还是上个推文的 03.Python Dash网页开发:多页面网站制作
把app全部文件目录复制到~/bioquest
文件夹下
并且需要再app.py
文件最后一行加上,因为wsgi从app.py
中导入并运行的是server
代码语言:Python
复制
server = app.server
Create wsgi.py
代码语言:Python
复制
# vi ~/bioquest/wsgi.py
from app import server as application
if __name__ == '__main__':
application.run()
Create index.ini
代码语言:Python
复制
# vi ~/bioquest/index.ini
[uwsgi]
module = wsgi
master = true
processes = 2
socket = index.scok
chmod-socket = 770
vacuum = true
die-on-term = true
py-autoreload = 1
Create index.service
代码语言:Python
复制
# sudo vi /etc/systemd/system/index.service
[Unit]
Description=uWSGI instance to serve index
After=network.target
[Service]
User=ubuntu
Group=www-data
WorkingDirectory=/home/ubuntu/bioquest
ExecStart=/home/ubuntu/micromamba/envs/dash/bin/uwsgi --force-cwd /home/ubuntu/bioquest --ini index.ini
StandardError=syslog
[Install]
WantedBy = multi-user.target
start and check
代码语言:Python
复制
sudo systemctl restart index.service
sudo systemctl status index.service
现在的~/bioquest
文件夹
代码语言:YAML
复制
app.py
index.ini
index.sock
pages
__pycache__
static
wsgi.py
dash.yaml
Configure Nginx
修改Nginx默认配置文件default。腾讯云服务器绑定域名需要备案,比较麻烦,所以暂时还是不搞吧。
需要在腾讯云服务器开一个新端口1314,如果用80或433应该就不需要新开端口了,因为一般都会默认开通。
代码语言:shell
复制
sudo apt install nginx
sudo vi /etc/nginx/sites-available/default
代码语言:shell
复制
server {
listen 1314;
server_name 111.230.57.251;
location / {
include uwsgi_params;
uwsgi_pass unix:/home/ubuntu/bioquest/index.sock;
}
}
修改Nginx配置,把user改为启动用户即root
代码语言:YAML
复制
sudo vi /etc/nginx/nginx.conf
代码语言:shell
复制
user root;
启动所有服务
代码语言:shell
复制
sudo systemctl daemon-reload sudo systemctl start index.service sudo systemctl enable index sudo systemctl start nginx sudo systemctl enable nginx sudo systemctl status index sudo service nginx restart
#访问和错误日志
#/var/log/nginx/access.log
#/var/log/nginx/error.log
现在就可以在浏览器中访问到DASH网站了http://111.230.57.251/
