## Automatic Update on CentOS/Red Hat

Automatic rippled updates can be enabled with a one-time Cron configuration:

1. Check that `/opt/ripple/bin/update-rippled.sh` exists. If it does not, [update manually](#manual-update-on-centosred-hat).

2. Install `crond`:

        $ sudo yum install cronie

3. Open the crontab file for editing

        $ sudo crontab -e

4. Add the following to the crontab file. Be sure to add a blank line at the end of the file.

        RANDOM_DELAY=59
        0 * * * * /opt/ripple/bin/update-rippled.sh


The script updates the installed `rippled` package within an hour of each new release.
