Various commercial enterprise programs to be had on Odoo consists of Open Source CRM, website builder, eCommerce, warehouse management, project management, billing & accounting, point of sale, human resources, marketing, manufacturing, buy control, among others.

An amazing point to note is that Odoo apps can be used as stand-alone applications, however in addition they combine seamlessly so you get a complete-featured Open Source ERP while you deploy numerous apps.

Step 1: Update Your System

As usual, update & upgrade your system & then reboot it to finish upgrading.

sudo apt update
sudo apt -y upgrade
sudo reboot

Step 2: Database

Make sure you’ve installed Database. I would recommend you to Install PostgreSQL if you haven’t installed it so far.

Step 3: Install wkhtmltopdf

Please follow the below guide on how to Install wkhtmltopdf as it is not present in Ubuntu repositories.

Step 4: Installing Odoo 13 on Ubuntu 18.04

Now, add Odoo repository to start Installing Odoo.

wget -O - https://nightly.odoo.com/odoo.key | sudo apt-key add -
echo "deb http://nightly.odoo.com/13.0/nightly/deb/ ./" | sudo tee /etc/apt/sources.list.d/odoo.list

Make an update & hit install Odoo command. Then press Y when prompted.

sudo apt udpate 
sudo apt install odoo

Check the status as it will auto start as soon as Installation of Odoo get completed.

systemctl status odoo

Then set it up to start every time when you do a boot.

sudo systemctl enable --now odoo

As the Odoo service uses port 8069, so let it confirm by

ss -tunelp | grep 8069

Step 5: Configure Nginx Proxy to Install Odoo

Fire the below command to Install nginx

sudo apt -y install nginx

Here we will consider the two scenarios for Nginx Proxy Configuration. One of them is HTTPS & when traffic is not served over secure connection. We will here consider the both steps.

Setting Up HTTP Proxy For Odoo

Set up new configuration file for Odoo & paste the data. Then set it according to your own requirements like changing server name.

sabi@Ubuntu:~$ sudo nano /etc/nginx/conf.d/odoo.conf

Odoo Upstreams
 upstream odooserver {
  server 127.0.0.1:8069;
 }
 server {
     listen 80;
     server_name erp.osradar.com;
     access_log /var/log/nginx/odoo_access.log;
     error_log /var/log/nginx/odoo_error.log;
 # Proxy settings proxy_read_timeout 720s; proxy_connect_timeout 720s; proxy_send_timeout 720s; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Real-IP $remote_addr; # Request for root domain location / {    proxy_redirect off;    proxy_pass http://odooserver; } # Cache static files location ~* /web/static/ {     proxy_cache_valid 200 90m;     proxy_buffering on;     expires 864000;     proxy_pass http://odooserver; } # Gzip gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript; gzip on;
 }

Don’t forget to change erp.osradar.com with yours. Keep in mind that a valid DNS record is required for external access.
See the config syntax:

sabi@Ubuntu:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Make sure settings are ok, then restart nginx services.

sudo systemctl restart nginx

Check that no error found. If you encountered an issue, then try the below command if you’ve installed Apache server.

sudo killall apache2

Now, restart Nginx services and check status it should be running fine.

Using Up Let’s Encrypt SSL Certificate For Odoo on Nginx

For security reasons, make sure to Encrypt Odoo on Nginx. You can choose any purchased SSL but here I’m using Free SSL Let’s Encrypt.
Follow the below procedure to get SSL certificate for your domain.

wget https://dl.eff.org/certbot-auto
 chmod +x certbot-auto
 sudo mv certbot-auto /usr/local/bin/certbot-auto
 sudo systemctl stop nginx
 export DOMAIN="erp.osradar.com"
 export EMAIL="info@osradar.com"
 sudo /usr/local/bin/certbot-auto certonly --standalone -d ${DOMAIN} --preferred-challenges http --agree-tos -n -m ${EMAIL} --keep-until-expiring

Note: Replace osradar.com with your domain.

When the execution success, paths to the certificate & chain files will be printed out.

IMPORTANT NOTES:
 Congratulations! Your certificate and chain have been saved at:
 /etc/letsencrypt/live/erp.osradar.com/fullchain.pem
 Your key file has been saved at:
 /etc/letsencrypt/live/erp.osradar.com/privkey.pem
 Your cert will expire on 2020-01-17. To obtain a new or tweaked
 version of this certificate in the future, simply run certbot-auto
 again. To non-interactively renew all of your certificates, run
 "certbot-auto renew"
 Your account credentials have been saved in your Certbot
 configuration directory at /etc/letsencrypt. You should make a
 secure backup of this folder now. This configuration directory will
 also contain certificates and private keys obtained by Certbot so
 making regular backups of this folder is ideal.
 If you like Certbot, please consider supporting our work by:
 Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
 Donating to EFF:                    https://eff.org/donate-le 

To renew certificate , create a cron

sudo crontab -e
 15 3 * * * /usr/local/bin/certbot-auto renew --pre-hook "systemctl stop nginx" --post-hook "systemctl start nginx"

Then create a new configuration file of odoo

sudo vim /etc/nginx/conf.d/odoo.conf

Modify & paste the below data into the file and save it.

Odoo Upstreams
 upstream odooserver {
  server 127.0.0.1:8069;
 }
 http to https redirection
 server {
     listen 80;
     server_name erp.osradar.com;
     return 301 https://erp.osradar.com$request_uri;
 }
 server {
     listen 443 ssl;
     server_name erp.osradar.com;
     access_log /var/log/nginx/odoo_access.log;
     error_log /var/log/nginx/odoo_error.log;
 # SSL
     ssl_certificate /etc/letsencrypt/live/erp.osradar.com/fullchain.pem;
     ssl_certificate_key /etc/letsencrypt/live/erp.osradar.com/privkey.pem;
     ssl_trusted_certificate /etc/letsencrypt/live/erp.osradar.com/chain.pem;
 # Proxy settings proxy_read_timeout 720s; proxy_connect_timeout 720s; proxy_send_timeout 720s; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Real-IP $remote_addr; # Request for root domain location / {    proxy_redirect off;    proxy_pass http://odooserver; } # Cache static files location ~* /web/static/ {     proxy_cache_valid 200 90m;     proxy_buffering on;     expires 864000;     proxy_pass http://odooserver; } # Gzip Compression gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript; gzip on;
 }

Now, restart nginx services to take effects.

sudo systemctl restart nginx

Step 6: Access Odoo Web Interface

You can access Odoo by typing your domain name in web browser or at localhost:8069/. You will be prompted to create a database first.

Then you will be redirected to Odoo dashboard after creating database.

Here you can perform all the tasks you want and you can use Odoo Apps. So, this is how you can Install Odoo & from Odoo dashboard Install oddo apps.
