This document describes basic steps to set up Odoo in production or on an internet-facing server. It follows installation, and is not generally necessary for a development systems that is not exposed on the internet.
If you are setting up a public server, be sure to check our Security recommandations!
Odoo is a multi-tenant system: a single Odoo system may run and serve a number of database instances. It is also highly customizable, with customizations (starting from the modules being loaded) depending on the "current database".
This is not an issue when working with the backend (web client) as a logged-in company user: the database can be selected when logging in, and customizations loaded afterwards.
However it is an issue for non-logged users (portal, website) which aren't bound to a database: Odoo needs to know which database should be used to load the website page or perform the operation. If multi-tenancy is not used that is not an issue, there's only one database to use, but if there are multiple databases accessible Odoo needs a rule to know which one it should use.
That is one of the purposes of
it specifies how the database should be selected based on the hostname (domain)
that is being requested. The value is a regular expression, possibly
including the dynamically injected hostname (
%h) or the first subdomain
%d) through which the system is being accessed.
For servers hosting multiple databases in production, especially if
is used, dbfilter must be set, otherwise a number of features will not work
- show only databases with names beginning with 'mycompany'
[options] dbfilter = ^mycompany.*$
- Show only databases matching the first subdomain after
www: for example the database "mycompany" will be shown if the incoming request was sent to
mycompany.co.uk, but not for
[options] dbfilter = ^%d$
Setting a proper
--db-filter is an important part
of securing your deployment.
Once it is correctly working and only matching a single database per hostname, it
is strongly recommended to block access to the database manager screens,
and to use the
--no-database-list startup paramater to prevent listing
your databases. See also security.
By default, PostgreSQL only allows connection over UNIX sockets and loopback connections (from "localhost", the same machine the PostgreSQL server is installed on).
UNIX socket is fine if you want Odoo and PostgreSQL to execute on the same machine, and is the default when no host is provided, but if you want Odoo and PostgreSQL to execute on different machines 1 it will need to listen to network interfaces 2, either:
- only accept loopback connections and use an SSH tunnel between the machine on which Odoo runs and the one on which PostgreSQL runs, then configure Odoo to connect to its end of the tunnel
- accept connections to the machine on which Odoo is installed, possibly over ssl (see PostgreSQL connection settings for details), then configure Odoo to connect over the network
- allow tcp connection on localhost
- allow tcp connection from 192.168.1.x network
# IPv4 local connections: host all all 127.0.0.1/32 md5 host all all 192.168.1.0/24 md5
listen_addresses = 'localhost,192.168.1.2' port = 5432 max_connections = 80
Out of the box, Odoo connects to a local postgres over UNIX socket via port 5432. This can be overridden using the database options when your Postgres deployment is not local and/or does not use the installation defaults.
The packaged installers will automatically
create a new user (
odoo) and set it as the database user.
- The database management screens are protected by the
admin_passwdsetting. This setting can only be set using configuration files, and is simply checked before performing database alterations. It should be set to a randomly generated value to ensure third parties can not use this interface.
- all database operations use the database options, including the database management
screen. For the database management screen to work requires that the PostgreSQL user
users can always drop databases they own. For the database management screen to be completely non-functional, the PostgreSQL user needs to be created with
no-createdband the database must be owned by a different PostgreSQL user.
the PostgreSQL user must not be a superuser
- connect to a PostgreSQL server on 192.168.1.2
- port 5432
- using an 'odoo' user account,
- with 'pwd' as a password
- filtering only db with a name beginning with 'mycompany'
[options] admin_passwd = mysupersecretpassword db_host = 192.168.1.2 db_port = 5432 db_user = odoo db_password = pwd dbfilter = ^mycompany.*$
Odoo includes built-in HTTP servers, using either multithreading or multiprocessing.
For production use, it is recommended to use the multiprocessing server as it increases stability, makes somewhat better use of computing resources and can be better monitored and resource-restricted.
- Multiprocessing is enabled by configuring
a non-zero number of worker processes, the number of workers should be based on the number of cores in the machine (possibly with some room for cron workers depending on how much cron work is predicted)
- Worker limits can be configured based on the hardware configuration to avoid resources exhaustion
multiprocessing mode currently isn't available on Windows
Worker number calculation
- Rule of thumb : (#CPU * 2) + 1
- Cron workers need CPU
- 1 worker ~= 6 concurrent users
memory size calculation
- We consider 20% of the requests are heavy requests, while 80% are simpler ones
- A heavy worker, when all computed field are well designed, SQL requests are well designed, ... is estimated to consume around 1Go of RAM
- A lighter worker, in the same scenario, is estimated to consume around 150MB of RAM
Needed RAM = #worker * ( (light_worker_ratio * light_worker_ram_estimation) + (heavy_worker_ratio * heavy_worker_ram_estimation) )
In multiprocessing, a dedicated LiveChat worker is automatically started and
the longpolling port but
the client will not connect to it.
Instead you must have a proxy redirecting requests whose URL starts with
/longpolling/ to the longpolling port. Other request should be proxied to
normal HTTP port
- Server with 4 CPU, 8 Thread
- 60 concurrent users
- 60 users / 6 = 10 <- theorical number of worker needed
- (4 * 2) + 1 = 9 <- theorical maximal number of worker
- We'll use 8 workers + 1 for cron. We'll also use a monitoring system to measure cpu load, and check if it's between 7 and 7.5 .
- RAM = 9 * ((0.8*150) + (0.2*1024)) ~= 3Go RAM for Odoo
[options] limit_memory_hard = 1677721600 limit_memory_soft = 629145600 limit_request = 8192 limit_time_cpu = 600 limit_time_real = 1200 max_cron_threads = 1 workers = 8
Whether it's accessed via website/web client or web service, Odoo transmits authentication information in cleartext. This means a secure deployment of Odoo must use HTTPS3. SSL termination can be implemented via just about any SSL termination proxy, but requires the following setup:
- enable Odoo's
proxy mode. This should only be enabled when Odoo is behind a reverse proxy
- set up the SSL termination proxy (Nginx termination example)
- set up the proxying itself (Nginx proxying example)
- your SSL termination proxy should also automatically redirect non-secure connections to the secure port
In case you are using the Point of Sale module in combination with a POSBox,
you must disable the HTTPS configuration for the route
/pos/web to avoid
- redirect http requests to https
- proxy requests to odoo
proxy_mode = True
Odoo as a WSGI Application
It is also possible to mount Odoo as a standard WSGI application. Odoo
provides the base for a WSGI launcher script as
script should be customized (possibly after copying it from the setup directory) to correctly set the
configuration directly in
odoo.tools.config rather than through the
command-line or a configuration file.
However the WSGI server will only expose the main HTTP endpoint for the web client, website and webservice API. Because Odoo does not control the creation of workers anymore it can not setup cron or livechat workers
To run cron jobs for an Odoo deployment as a WSGI application requires
- a classical Odoo (run via
- connected to the database in which cron jobs have to be run (via
- which should not be exposed to the network. To ensure cron runners are not
network-accessible, it is possible to disable the built-in HTTP server
odoo-bin --no-xmlrpcor setting
xmlrpc = Falsein the configuration file
The second problematic subsystem for WSGI deployments is the LiveChat: where most HTTP connections are relatively short and quickly free up their worker process for the next request, LiveChat require a long-lived connection for each client in order to implement near-real-time notifications.
This is in conflict with the process-based worker model, as it will tie up worker processes and prevent new users from accessing the system. However, those long-lived connections do very little and mostly stay parked waiting for notifications.
The solutions to support livechat/motifications in a WSGI application are:
- deploy a threaded version of Odoo (instread of a process-based preforking
one) and redirect only requests to URLs starting with
/longpolling/to that Odoo, this is the simplest and the longpolling URL can double up as the cron instance.
- deploy an evented Odoo via
odoo-geventand proxy requests starting with
the longpolling port.
Serving Static Files
For development convenience, Odoo directly serves all static files in its modules. This may not be ideal when it comes to performances, and static files should generally be served by a static HTTP server.
Odoo static files live in each module's
static/ folder, so static files
can be served by intercepting all requests to
and looking up the right module (and file) in the various addons paths.
For starters, keep in mind that securing an information system is a continuous process, not a one-shot operation. At any moment, you will only be as secure as the weakest link in your environment.
When deploying an internet-facing server, please be sure to consider the following security-related topics:
- Always set a strong super-admin admin password, and restrict access to the database management pages as soon as the system is set up. See Database Manager Security.
- Choose unique logins and strong passwords for all administrator accounts on all databases. Do not use 'admin' as the login. Do not use those logins for day-to-day operations, only for controlling/managing the installation. Never use any default passwords like admin/admin, even for test/staging databases.
- Use appropriate database filters (
--db-filter) to restrict the visibility of your databases according to the hostname. See dbfilter.
- Once your
db_filteris configured and only matches a single database per hostname, you should set
list_dbconfiguration option to
False, to prevent listing databases entirely (this is also exposed as the
- Make sure the PostgreSQL user (
--db_user) is not a super-user, and that your databases are owned by a different user. For example they could be owned by the
postgressuper-user if you are using a dedicated non-privileged
db_user. See also Configuring Odoo.
- Keep installations updated by regularly installing the latest builds, either via GitHub or by downloading the latest version from https://www.odoo.com/page/download or http://nightly.odoo.com
- Configure your server in multi-process mode with proper limits matching your typical usage (memory/CPU/timeouts). See also Builtin server.
- Run Odoo behind a web server providing HTTPS termination with a valid SSL certificate,
in order to prevent eavesdropping on cleartext communications. SSL certificates are
cheap, and many free options exist.
Configure the web proxy to limit the size of requests, set appropriate timeouts,
and then enable the
proxy modeoption. See also HTTPS.
- Whenever possible, host your public-facing demo/test/staging instances on different machines than the production ones. And apply the same security precautions as for production.
- If you are hosting multiple customers, isolate customer data and files from each other using containers or appropriate "jail" techniques.
- Setup daily backups of your databases and filestore data, and copy them to a remote archiving server that is not accessible from the server itself.
Database Manager Security
Configuring Odoo mentioned
admin_passwd in passing.
This setting is used on all database management screens (to create, delete, dump or restore databases).
If the management screens must not be accessible, or must only be accessible
from a selected set of machines, use the proxy server's features to block
access to all routes starting with
/web/database except (maybe)
/web/database/selector which displays the database-selection screen.
If the database-management screen should be left accessible, the
admin_passwd setting must be changed from its
admin default: this
password is checked before allowing database-alteration operations.
It should be stored securely, and should be generated randomly e.g.
$ python -c 'import base64, os; print(base64.b64encode(os.urandom(24)))'
which will generate a 32 characters pseudorandom printable string.
Odoo is supported by multiple browsers for each of its versions. No distinction is made according to the browser version in order to be up-to-date. Odoo is supported on the current browser version. The list of the supported browsers by Odoo version is the following:
