Try to use centos nginx + uwsgi to deploy a previous django project. The process of solving the problem is long and arduous, but it turns out to be worthwhile. If you are deploying a Django project, I hope it can help you
Prerequisites
What I use: python3.6 mysql5.7 django project 3.2
First, download python and pip in centos, and use git to download the django project in the gitee warehouse.
Text
Install virtualenv
pip install virtualenv
Create an aa — virtual environment
mkdir /env virtualenv /env/aa --python=python3.6.8
Activate the virtual environment
source /env/aa/bin/activate
Exit the virtual environment is deactivate
Enter the virtual environment as shown in the figure
mysql installation and remote connection
The higher version of mysql is compatible with the lower version
Install mysql yum install mysql-server start mysql sudo systemctl start mysqld state sudo systemctl status mysqld
The status after the installation is started is as follows
Connect to local mysql remotely
mysql -uroot -p
The first time I installed it, I directly entered the mysql interface (and…remember to add port 3306 to your security group). At this time, there was a problem about permissions in the remote connection, which made it impossible to connect to the database—>mysql– ->user needs to be changed
update user set host="%" where user = "root";
Open the local navacat mysql
Connection name: any
Host/ip address: your Alibaba Cloud virtual machine public network IP/virtual machine address
Don’t fill in others for the time being because no password is set for the first time
The connection test is completed. After creating the connection, directly create a db dier with the same name in navacat mysql to replace the previous database
Dump to the current database with the same name, and then try to query it in linux
Local operation of django project
Go to the directory of your project and run manage.py
cd /home/www/day1
python manage.py runserver if python manage.py runserver 0.0.0.1:8000 You can try public network ip:8000 to visit (security group plus port)
Pictures of successful local operations
If not successful, such as the question: Did you install mysqlclient? You need to install the corresponding dependency package
pip install Django pip install pillow pip install mysqlclient or yum install mysql-devel .....
Attachment: If your django project setting.py connects to the database with a password, you need to change the password. I won’t go into details here
Install uwsgi + nginx
In fact, the important thing is to modify the two files
pip install libpcre3 libpcre3-dev pip install uwsgi pip install nginx
Enter /etc/nginx to modify nginx.conf (here is written and copied directly)
Modify the server_name domain name in http—“server
Must change location /static {alias /home/www/day1/app02/static; }
It is the static file of the django project that has no style and these cannot be loaded

systemctl start nginx starts the service or restarts the service in the sbin directory ./nginx -s reload
Then verify in the nginx directory
cd /etc/nginx nginx -t
The following code appears to indicate that the configuration is complete
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful
At this time, access the public network ip:80 as shown in the figure
Next configure uwsgi
Create a new file aa_uwsgi.ini in the django—“manage.py directory with content
chdir the project directory under the virtual environment
module = where wsgi.py in the project is located
virtualenv= about independent python environment
[uwsgi] socket=127.0.0.1:8000 chdir=/home/www/day1 module = djago2jie.wsgi virtualenv=/env/aa/ processes=1 master = true vacuum = true buffer-size=65535
Finish saving and then run this file uwsgi –ini aa_uwsgi.ini in the django project directory
Web page public network ip:80/home page access, mobile terminal can also access
And the port configured in the security group
Stay: domain name resolution
