There are two ways to see the Odoo Logs. One is rough and can be used to see the latest Odoo logs, it’s the Journal tools. You may do this using the following if your Odoo service is installed as odoo13 for example
journalctl -u odoo13
Note: If you are having trouble primarily in installing Odoo properly, you may check the following:
The other way, is the enable logging to a file. This has to be enabled from the odoo.conf file which is located under /etc/ folder. First we open the /etc/odoo.conf file:
nano /etc/odoo.conf
Now, search to see if you have a directive called ‘logfile’. If you don’t, you may add the following to /etc/odoo.conf:
logfile = /var/log/odoo13/odoo.log
If you already have the directive, but commented out, like this:
; logfile = /var/log/odoo13/odoo.log
You may remove the ‘;’ in front of the logfile directive and save the file. Now you may restart your Odoo instance to allow odoo log the information to the file /var/log/odoo13/odoo.log
systemctl restart odoo13
If the restart showing some errors, probably because it is failing to put permission to odoo13 folder. You may try the following:
mkdir /var/log/odoo13 chown -Rf odoo:odoo /var/log/odoo13 systemctl restart odoo13
