Apache2 ssl configuration for odoo 15

Odoo default port is 8069. You can follow this instruction to convert your http odoo server to a ssl server. In case you change the workers on odoo, you need to redirect /longpolling in the apache config file. Otherwise, odoo could not access to longpolling address and the bus would not work.

Prerequisits:

1. Linix server ( Ubunto, Debian )
2. Apache2 installed
3. odoo 15 installed
4. you need a registerd web domain
5. you need to buy a ssl certificate or setup let'sEncrypt one

a) odoo config

• edit the /etc/odoo/odoo.conf

http_port = 8069
longpolling_port = 8072
proxy_mode = True 
workers = 4

• reboot odoo

systemctl restart odoo

b) Install apache extentions

on your linux server:

a2enmod proxy
a2enmod proxy_http 
a2enmod ssl

c) Redirect http to http

• edit /etc/apache2/site-available/<youDomain.com>.conf

<VirtualHost *:80>
    ServerName <yourDomain.com>
    Redirect permanent / https://<yourDomain.com>/
</VirtualHost>

<VirtualHost *:443>
    Servername <yourDomain.com>
    SSLEngine on
    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateKeyFile /etc/ssl/<yourDomain.com>/privkey.pem
    SSLCertificateFile  /etc/ssl/<yourDomain.com>/fullchain.pem
    SSLProxyEngine on
    RequestHeader set "X-Forwarded-Proto" "https"
    SetEnv proxy-nokeepalive 1
    
    ProxyPass /longpolling http://<yourDomain.com>:8072/longpolling
    ProxyPassReverse /longpolling http://<yourDomain.com>:8072/longpolling
    
    ProxyPass / http://<yourDomain.com>:8069/
    ProxyPassReverse / http://<yourDomain.com>:8069/
    

    ProxyErrorOverride off
