   1. `wget https://fsl.fmrib.ox.ac.uk/fsldownloads/fslinstaller.py # this may work`
   2. `yum install python2`
   3. `python2 fslinstaller.py`

#### Install NiDB

1. Download the latest .rpm package
2. `yum --nogpgcheck localinstall nidb-xxxx.xx.xx-1.el8.x86_64.rpm`
3. Secure the MariaDB installation by running `sudo mysql_secure_installation` and using the following responses

```bash
    Enter current password for root (enter for none):
    Change the root password? [Y/n] n
    Remove anonymous users? [Y/n] Y
    Disallow root login remotely? [Y/n] Y
    Remove test database and access to it? [Y/n] Y

1. **Finish Setup** - Use Firefox to view <http://localhost/setup.php> . Follow instructions on the page to configure the server
   * The setup page must be accessed from localhost -or- the config file must be manually edited to include the IP address of the computer you are using the access setup.php.
   * Edit `/nidb/nidb.cfg` and add your IP address (comma separated list) to the `[setupips]` config variable. It should look something like `[setupips] 127.0.0.1, 192.168.0.1` depending on the IP(s)
