        # Deployment

+ Install Apache

```

$ apt-get update

$ apt-get install python3-pip apache2 libapache2-mod-wsgi-py3

```

+ Change dir: `$ cd /var/www/`

+ Clone the repo: `$ git clone https://github.com/suhailvs/upwork_temp`

+ Change dir: `$ cd upwork_temp`

+ Create virtual and install django:

```

$ pip3 install virtualenv

$ virtualenv env

$ source ./env/bin/activate

$ pip install django

$ pip install celery

```

+ Migrate and sync db and give permission to media:

```

$ mkdir media

$ chmod 777 media

$ ./manage.py makemigrations

$ ./manage.py migrate

$ ./manage.py loaddata users.json

$ cd media/

$ chmod 777 db.sqlite3

```

+ Edit apache config :

```

$ vi /etc/apache2/sites-available/upwork_temp.conf

    ServerName ng.helpservice.xyz

    WSGIDaemonProcess upworkapp python-home=/var/www/upwork_temp/env python-path=/var/www/upwork_temp

    WSGIProcessGroup upworkapp

    WSGIScriptAlias / /var/www/upwork_temp/sampleapp/wsgi.py

    ErrorLog /var/www/upwork_temp/error.log

    CustomLog /var/www/upwork_temp/access.log combined

```

+ restart apache: `service apache2 reload`

## Nginx & Gunicorn   

### Gunicorn setup

https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-18-04

    pip install gunicorn

    gunicorn --bind 0.0.0.0:8000 sampleapp.wsgi

Creating systemd Socket and Service Files for Gunicorn

    # sudo vim /etc/systemd/system/gunicorn.socket

    [Unit]

    Description=gunicorn socket

    [Socket]

    ListenStream=/run/gunicorn.sock

    [Install]

    WantedBy=sockets.target

service

    # sudo vim /etc/systemd/system/gunicorn.service

    [Unit]

    Description=gunicorn daemon

    Requires=gunicorn.socket

    After=network.target

    [Unit]

    Description=gunicorn daemon

    Requires=gunicorn.socket

    After=network.target

    [Service]

    User=sammy

    Group=www-data

    WorkingDirectory=/home/suhail/github/flavour

    ExecStart=/home/suhail/github/flavour/env/bin/gunicorn \

              --access-logfile - \

              --workers 3 \

              --bind unix:/run/gunicorn.sock \

              mysite.wsgi:application

    [Install]

    WantedBy=multi-user.target

We can now start and enable the Gunicorn socket. 

    sudo systemctl start gunicorn.socket

    sudo systemctl enable gunicorn.socket

Check your /etc/systemd/system/gunicorn.service file for problems. If you make changes to the /etc/systemd/system/gunicorn.service file, reload the daemon to reread the service definition and restart the Gunicorn process by typing:

    sudo systemctl daemon-reload

    sudo systemctl restart gunicorn

### nginx 

sudo apt update

    sudo apt install nginx

You have to go to the file `/etc/nginx/sites-enabled/default` edit port 81:

    server {

        listen 81 default_server;

        listen [::]:81 default_server;

        location / {

            include proxy_params;

            proxy_pass http://unix:/run/gunicorn.sock;

        }

    }

        

Restart the server;

    sudo service nginx restart

  

    

# Celery Installation

+ Install Rabbitmq:

```

$ echo 'deb http://www.rabbitmq.com/debian/ testing main' |

     sudo tee /etc/apt/sources.list.d/rabbitmq.list

$ apt-get update

$ apt-get install rabbitmq-server

```

+ Daemonization

here is a [nice tutorial](https://medium.com/@yehandjoe/celery-4-periodic-task-in-django-9f6b5a8c21c7)

`$ apt-get install supervisor`

Then, add `/etc/supervisor/conf.d/celery_proj_worker.conf` file:

```

; ==================================

; celery worker supervisor example

; ==================================

; the name of your supervisord program

[program:projworker]

; Set full path to celery program if using virtualenv

command=/var/www/upwork_temp/env/bin/celery -A sampleapp worker -l info

; The directory to your Django project

directory=/var/www/upwork_temp

; If supervisord is run as the root user, switch users to this UNIX user account before doing any processing.

; user=me

; Supervisor will start as many instances of this program as named by numprocs

numprocs=1

; Put process stdout output in this file stdout_logfile=/var/log/celery/proj_worker.log

; Put process stderr output in this file stderr_logfile=/var/log/celery/proj_worker.log

; If true, this program will start automatically when supervisord is started

autostart=true

; May be one of false, unexpected, or true. If false, the process will never be autorestarted. If unexpected, the process will be restart when the program exits with an exit code that is not one of the exit codes associated with this process’ configuration (see exitcodes). If true, the process will be unconditionally restarted when it exits, without regard to its exit code.

autorestart=true

; The total number of seconds which the program needs to stay running after a startup to consider the start successful.

startsecs=10

; Need to wait for currently executing tasks to finish at shutdown. ; Increase this if you have very long running tasks.

stopwaitsecs = 600 

; When resorting to send SIGKILL to the program to terminate it ; send SIGKILL to its whole process group instead, taking care of its children as well.

killasgroup=true

; if your broker is supervised, set its priority higher so it starts first

priority=998

```

Also add `/etc/supervisor/conf.d/celery_proj_beat.conf` file:

```

; ================================

;  celery beat supervisor example

; ================================

; the name of your supervisord program

[program:projbeat]

; Set full path to celery program if using virtualenv

command=/var/www/upwork_temp/env/bin/celery -A sampleapp beat -l info

; The directory to your Django project

directory=/var/www/upwork_temp

; If supervisord is run as the root user, switch users to this UNIX user account before doing any processing.

;user=me

; Supervisor will start as many instances of this program as named by numprocs

numprocs=1

; Put process stdout output in this file stdout_logfile=/var/log/celery/proj_beat.log

; Put process stderr output in this file stderr_logfile=/var/log/celery/proj_beat.log

; If true, this program will start automatically when supervisord is started

autostart=true

; May be one of false, unexpected, or true. If false, the process will never be autorestarted. If unexpected, the process will be restart when the program exits with an exit code that is not one of the exit codes associated with this process’ configuration (see exitcodes). If true, the process will be unconditionally restarted when it exits, without regard to its exit code.

autorestart=true

; The total number of seconds which the program needs to stay running after a startup to consider the start successful.

startsecs=10

; if your broker is supervised, set its priority higher so it starts first

priority=999

```

update change for supervisor:

```

$ supervisorctl reread

$ supervisorctl update

```

Finally we can `start/stop/restart` the services or even check the status:

```

$ supervisorctl start projworker

$ supervisorctl stop projworker

$ supervisorctl restart projworker

$ supervisorctl status projworker

$ supervisorctl start projbeat

$ supervisorctl stop projbeat

$ supervisorctl restart projbeat

$ supervisorctl status projbeat

```

checkout log in:

`$ /var/log/supervisor`

# lets encrypt for HTTPS

https://github.com/certbot/certbot/issues/1820

I had to comment the `WSGIDaemonProcess` line out before running letsencrypt. 

in `/etc/apache2/sites-available/upwork_temp.conf`::

    

        ServerName ng.helpservice.xyz

        # WSGIDaemonProcess upworkapp python-home=/var/www/upwork_temp/env python-path=/var/www/upwork_temp

https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04

    apt-get install python3-certbot-apache

    certbot --apache -d example.com -d www.example.com

Then uncommented `WSGIDaemonProcess`.
