Odoo [Errno 98] Address already in use

Sometimes you may encounter an error in development or production [Errno 98] Address already in use.
This error is due to openerp-service or some other service already use port defined in your Odoo config.
You could try to change the port 8069 to any other port  and restart the server but that’s not the right way.

Just apply the command

sudo ps aux | grep openerp

which will show you the port on which openerp server is in running state.
Then kill the specific process.

sudo kill -9 id

For example sudo kill -9 999

Restart odoo server and that’s it.

 

Disable sudo timeout on Ubuntu in terminal

By default sudo remembers your password for 15 minutes.

Disable sudo timeout with this command:

sudo sh -c 'echo "\nDefaults timestamp_timeout=-1">>/etc/sudoers'

To re-enable sudo timeout use this command:

sudo sed -i "/Defaults timestamp_timeout=-1/d" /etc/sudoers

You can also change or disable sudo timeout with visudo.

sudo visudo

This opens an editor and points it to the sudoers file — Ubuntu defaults to nano, other systems use Vi.

To the defaults line, add :

timestamp_timeout=2

So it will look like this:

Defaults env_reset,timestamp_timeout=20

You might want to read the sudoers manual pages for additional information.
