## Run n8n on own server
|
||||
|
||||
To run n8n on your webserver with own domain some environment variables
|
||||
should be set to the appropriate values.
|
||||
|
||||
A possible configuration to run n8n on `https://n8n.example.com/` would look
|
||||
like this:
|
||||
|
||||
```
|
||||
N8N_HOST: "n8n.example.com"
|
||||
N8N_PROTOCOL: "https"
|
||||
N8N_PORT: "443"
|
||||
VUE_APP_URL_BASE_API: "https://n8n.example.com/"
|
||||
```
|
||||
|
||||
***Important***: Make sure that you secure your n8n instance like described above in "Securing n8n"!
|
||||
|
||||
|
||||
## Additional Configuration
|
||||
|
||||
It is possible to change some of the n8n defaults via special environment variables.
|
||||
The ones that currently exist are:
|
||||
|
||||
|
||||
### EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS
|
||||
|
||||
Normally executions which got started via the Editor UI will not be saved as
|
||||
they are normally only for testing and debugging. That default can be changed
|
||||
with this environment variable.
|
||||
|
||||
```
|
||||
EXECUTIONS_DATA_SAVE_MANUAL_EXECUTIONS=true
|
||||
```
|
||||
|
||||
This setting can also be overwritten on a per workflow basis in the workflow
|
||||
settings in the Editor UI.
|
||||
|
||||
|
||||
### EXECUTIONS_DATA_SAVE_ON_ERROR / EXECUTIONS_DATA_SAVE_ON_SUCCESS
|
||||
|
||||
When a workflow gets executed it will save the result in the database. That is
|
||||
the case for executions that did succeed and for the ones that failed. That
|
||||
default behavior can be changed like this:
|
||||
|
||||
```
|
||||
EXECUTIONS_DATA_SAVE_ON_ERROR=true
|
||||
EXECUTIONS_DATA_SAVE_ON_SUCCESS=false
|
||||
```
|
||||
|
||||
These settings can also be overwritten on a per workflow basis in the workflow
|
||||
settings in the Editor UI.
|
||||
|
||||
|
||||
### GENERIC_TIMEZONE
|
||||
|
||||
The timezone is set by default to "America/New_York". It gets for example used by the
|
||||
Cron-Node to know at what time the workflow should be started at. To set a different
|
||||
default timezone simply set `GENERIC_TIMEZONE` to the appropriate value like for example
|
||||
for Berlin (Germany):
|
||||
|
||||
```
|
||||
GENERIC_TIMEZONE="Europe/Berlin"
|
||||
```
|
||||
|
||||
You can find the name of your timezone here:
|
||||
[https://momentjs.com/timezone/](https://momentjs.com/timezone/)
|
||||
|
||||
|
||||
### NODES_EXCLUDE
|
||||
|
||||
It is possible to not allow users to use nodes of a specific node type. If you, for example,
|
||||
do not want that people can write data to disk with the "n8n-nodes-base.writeBinaryFile"
|
||||
node and can not execute commands with the "n8n-nodes-base.executeCommand" node you can
|
||||
set the following:
|
||||
|
||||
```
|
||||
NODES_EXCLUDE="[\"n8n-nodes-base.executeCommand\",\"n8n-nodes-base.writeBinaryFile\"]"
|
||||
```
