NginX + PostgreSQL + uWSGI + Django

1.Install PostgreSQL

rpm -Uvh https://yum.postgresql.org/10/redhat/rhel-7-x86_64/pgdg-centos10-10-2.noarch.rpm
yum install postgresql10-server postgresql10
/usr/pgsql-10/bin/postgresql-10-setup initdb

edit the following two conf files, configure who can access the site and what address the site listens to.

/var/lib/pgsql/10/data/postgresql.conf
/var/lib/pgsql/10/data/pg_hba.conf

CREATE DATABASE azendb;
CREATE USER azen WITH ENCRYPTED PASSWORD ‘password’;
GRANT ALL PRIVILEGES ON DATABASE azendb TO azen;

$ python manage.py migrate  
$ python manage.py makemigrations blogs  
$ python manage.py migrate  

pg_dump azendb > azendb.bak
psql azendb < azendb.bak

crontab to back up data regularly:
59 23 * * * /usr/bin/pg_dump “host=localhost hostaddr=127.0.0.1 port=5432 user=azen password=azen dbname=azendb” > azendb.bak

2.Install Python3.6

sudo yum install -y https://centos7.iuscommunity.org/ius-release.rpm

sudo yum update

sudo yum install -y python36u python36u-libs python36u-devel python36u-pip

Remember that yum, firewall-cmd, urlgrabber use python 2.7. Modify python files’ first line when necessary.

3.Django project folder

Pull codes

cd /var/www

git clone [e-mail]:xxx/xx.git (pull codes through ssh)

set up venv

python -m venv venv4zen

activate the virtual environment

source ./venv4azen/bin/activate

pip3 install Django  

pip3 install Django-Markdownx

deactivate

pip3 install psycopg2-binary

pip3 install uwsgi

4.Configure

make uwsgi.service file so that uWSGI can work as a deamon

touch /etc/systemd/system/uwsgi.service

[Unit]
Description = uWSGI Emperor
After = syslog.target

[Service]
ExecStart=/usr/local/bin/uwsgi --ini /etc/uwsgi/emperor.ini
ExecStop = kill -INT `cat /run/uwsgi.pid`
ExecReload = kill -TERM `cat /run/uwsgi.pid`
Restart = always
Type = notify
NitifyAccess = main
PIDFile = /run/uwsgi.pid

[Install]
Wantedby=multi-user.target

create uwsgi user.

useradd uwsgi -s /bin/false

create file /etc/uwsgi/emperor.ini

[uwsgi]
emperor = /etc/uwsgi/vassals
uid = uwsgi
gid = nginx
logto = /etc/uwsgi/log

create file azen.ini under /etc/uwsgi/vassals

[uwsgi]
socket = 127.0.0.1:3030
chdir = /var/www/azen
venv = /var/www/venv4azen
wsgi-file = azen/wsgi.py
uid = uwsgi
gid = nginx

#uwsgi --socket 127.0.0.1:3030  --chdir /var/www/azen --venv /var/www/azen/venv4azen --wsgi-file azen/wsgi.py --master --processes 4 --threads 2 --logto /etc/uwsgi/log

configure a file azen.conf under /etc/nginx/conf.d/

server{
	listen       80 default_server;
	listen       [::]:80 default_server;
	server_name  192.168.56.101;
	error_log    /var/www/azen/log/error_log;
	access_log   /var/www/azen/log/access_log;
	charset      utf-8;
	location /static/ {
		alias /var/www/azen/static/;
	}

	location / {
		include uwsgi_params;
		uwsgi_pass 127.0.0.1:3030;
	}
	}
