The result configuration is as follows ：

proxy_pass http://127.0.0.1:9000/;
}
}
Pay attention to python In the virtual environment of the project .
Use pip install gunicorn install gunicorn
After installation, you can start and stop the service by command .
Use the following command to start the project
gunicorn -w 5 -b 127.0.0.1:9000 wsgi:application
among 127.0.0.1:9000 yes flask The boot port of the application and IP,wsgi Is a startup project under the root directory of the project. The file name is wsgi.py application yes flask Instance object name .
Or use custom gunicorn.py The configuration file
gunicorn -c app/gunicorn_config.py wsgi:application
among .py It's a custom profile
as follows ：
import multiprocessing
bind = '0.0.0.0:9000' # binding ip And port number
backlog = 512 # Listening to the queue
chdir = '/usr/local/webserver/nginx/software_project' #gunicorn To switch to > working directory
timeout = 40 # Overtime
worker_class = 'gevent' # Use gevent Pattern , You can also use sync Pattern , The default is sync Pattern
workers = multiprocessing.cpu_count() * 2 # Number of processes
threads = 2 # Specify the number of threads to open per process
# Set maximum concurrency
worker_connections = 2000
# Set the process file directory
pidfile = '/var/run/gunicorn.pid'
step ：
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install epel-release
yum list | grep python3 | more
yum install python36
python3
It needs to be installed first python3 Environment .
1、 First , Use pip Command to install virtualenv modular ：
# pip3 install virtualenv
Test for successful installation
# virtualenv --version
Installation successful , The installed virtualenv Version number of
3、 Create a stand-alone operating environment , And name
# virtualenv --no-site-packages venv
venv Is the name of the virtual environment , You can name it according to your needs .
among Direct use command virtualenv You can create an independent Python Running environment , Add parameters **–no-site-packages**, You can install to the system Python The third-party packages in the environment are not controlled in the independent environment , In this way, we can get a without any third-party packages Python The environment .
4、 New Python The environment is placed in the current directory venv Catalog , With venv This Python Environmental Science , We can start using this virtual environment , It needs to be activated ：
# source venv/bin/activate
It should be noted that source In virtual environment bin In the catalog activate , After successful activation , We can see that the name of the virtual environment is added in front of the terminal command prompt
5、 If you don't use this virtual environment for the time being , sign out venv Environmental Science
(venv) # deactivate
6、 Other commands
① View the current virtual machine environment Directory
# worken
② Switch virtual environment
# workon venv2
③ Exit virtual environment
# deactivate
④ Delete virtual environment
# rmvirtualenv venv
Install and configure python A virtual environment virtualenv good after i, Is to install the third-party package required by the project , You can deploy the project to the server .
