Useful environment variables

The following environment variables influence how Zotonic starts up.

ZOTONIC_IP
Which IP address to bind the web server to. By default, it binds to any IP address. When running Zotonic behind a proxy like nginx or varnish, it is wise to put 127.0.0.1 here.
ZOTONIC_PORT
The port number to bind the web server to. Defaults to port 8000.
ZOTONIC_SMTP_LISTEN_IP
The IP address to bind the SMTP server to. Binds to any IP address by default.
ZOTONIC_SMTP_LISTEN_PORT
The port number to bind the SMTP server to. Defaults to port 2525.
ZOTONIC_SMTP_LISTEN_DOMAIN
The domain to bind the SMTP server to, if any.
TMP
Where Zotonic puts temporary files, like temporary files for image resizing or URL downloading.

Note

When the variables do not seem to have effect, check Zotonic’s priv/config file. The above variables are overridden by the ones in that file, at the moment.
