Post install

Setting up email

If there is only one thing to do after an install, it’s setting up email. Otherwise users will not be able to reset their password!

If a mail server is present, it will work out of the box. However, it is recommended to use an authenticated SMTP account to avoid the emails going to the spam folders of recipients. That is, unless your mail server is perfectly configured (with DKIM and SPF).

Go to the Sysadmin panel (a link is at the bottom left of a page) and add the requested infos.

If you don’t know what to do, I highly recommend using SMTP2GO, they provide a free plan that will probably be enough for your use case.

Register an account using this link: SMTP2GO. Once logged in, it will provide you with a login and password to connect to the SMTP server “”. Input these credentials on the Sysadmin panel and test sending an email.

Set up backup

See the backup page.

Set up the teams (optional)

The Sysadmin panel (sysconfig.php) allows you to add another team to your install. You should also edit your team name.

Set up timestamping (optional)

eLabFTW provides an easy way to do Trusted Timestamping for your experiments, so you can have strong legal value for your lab notebook.

By default, it is setup to use as TSA. It is free for researchers. The only problem, is that they don’t have ETSI certification for this service (although their PKI infrastructure is certified ETSI TS 102 042).

So if you need a stronger certification, you should go with a commercial solution providing an RFC 3161 way of timestamping documents. We recommend, as they are one of the most serious and recognized TSA out there, but feel free to use the one you prefer.

You need to add the root certificate of the TSA somewhere where elabftw can read it for this to work.

Remember: no data is sent to the TSA (TimeStampingAuthority), only the hash of the data is sent, so no information can leak!

Set up a cronjob to renew TLS certificates (optional)

If you installed it with a proper domain name and you used letsencrypt to get your TLS certificate, then you need to renew them every 3 months.

Create a script containing:

# stop webserver
docker exec elabftw supervisorctl stop nginx
# renew certificate
certbot renew
# and start the webserver again
docker exec elabftw supervisorctl start nginx

Add this script as a cronjob:

0 4 1 * * /root/

This line will run the script at 4am every 1st day of the month.

If the code above doesn’t work, try this:

# stop everything
elabctl stop
# renew certificate
certbot renew
# start elabftw
elabctl start

Set up a cronjob to clear the exported files:

When someone requests as .zip or .csv export, the file is stored on disk undefinitely. If you want to clear those files, feel free to delete the content of the cache folder (not the folder itself, but its content). If you are using Docker, the folder is in the container at /elabftw/cache. Note that this folder gets cleared at each container creation and for non docker install, it gets cleared when you are updating.

Update often

It is important to keep your install up to date with the latest bug fixes and new features.
