Network Asset Management

Python Installation

wget https://www.python.org/ftp/python/3.9.10/Python-3.9.10.tgz
tar -xf Python-3.9.10.tgz
cd Python-3.9.10
./configure --prefix=/usr/local/python39
make && make install
ln -s /usr/local/python39/bin/python3 /usr/bin/python3
ln -s /usr/local/python39/bin/pip3 /usr/bin/pip3

Python Virtual Environment Installation

Install virtualenv and virtualenvwrapper:

pip3 install virtualenv virtualenvwrapper
ln -s /usr/local/python39/bin/virtualenvwrapper.sh /usr/bin/virtualenvwrapper.sh
ln -s /usr/local/python39/bin/virtualenv /usr/bin/virtualenv

Add the following lines to ~/.bashrc:

export WORKON_HOME=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3
source /usr/bin/virtualenvwrapper.sh

Create a virtual environment with a specified version:
```
mkvirtualenv -p /usr/bin/python3 network_manage
```
Exit virtual environment:
```
deactivate
```
Delete virtual environment:
```
rmvirtualenv network_manage
```

Postgres Database Initialization

Create a new database directory:
```
mkdir /usr/local/network_manage/
```

Change the directory's owner group:

chown postgres:postgres /usr/local/network_manage/

Initialize the database directory:

su - postgres -c "initdb -D /usr/local/network_manage/"

Based on network detection and switch detection to manage IP assets.

Environment Deployment

Python 3.9+
Django 3.2
React 17.0

Backend Environment Deployment

Install the basic dependency packages, enter network_manage_api and execute:
```
pip install -r requirements.txt
```

Django database configuration:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'device_query',
        'USER': 'root',
        'PASSWORD': '*****',
        'HOST': '127.0.0.1',
        'OPTIONS': {
            "init_command": "SET foreign_key_checks = 0;",
        },
    }
}

Note: You need to create a new database in the database first: create database device_query

Environment configuration:

REDIS_CONF = {
  'host': '127.0.0.1',
  'password': '123456789',
  'port': 6379
}
DEVICE_QUERY_QUEUE = "device:query:queue"
DEVICE_QUERY_CRONTAB_HASH = "device:crontab:task:time"
SERVICE_INSTALL_PATH = "/opt/network_manage/"
SCRIPT_PATH = {
  'DEVICE_QUERY_CRON_PATH': "/opt/network_manage/bin/device_query_cron.py"
}
LOG_SETUP = {
  'LOG_FORMAT': "%(asctime)s %(name)s %(levelname)s %(filename)s %(message)s",
  'DATE_FORMAT': "%Y-%m-%d  %H:%M:%S",
  'SERVICE_MONITOR_PATH': "/opt/network_manage/log/serviceMonitor.log"
}

Start the Django service:

python manage.py makemigrations
python manage.py migrate
python manage.py runserver 0.0.0.0:8000

Enable service monitoring in the cron job:

*/1 * * * * /opt/network_manage/bin/service_monitor.sh >>/dev/null 2>&1

Frontend Environment Deployment

Install the npm environment, search online for installation instructions.
Install all dependencies listed in package.json with one command:
```
npm install
```
Start the npm service:
```
npm run start
```
