## Configuration ## Configuration
After you clone the base configuration, you will need to create a configuration file called `gravity-sync.conf` in the same folder as the script. There will be a file called `gravity-sync.conf.example` that you can use as the basis for your file. ### The Easy Way
Make a copy of the example file and modify it with your site specific settings. After you install Gravity Sync to your server (reguardless of the option you selected above) you will need to create a configuration file called `gravity-sync.conf` in the same folder as the script.
```
./gravity-sync config
```
This will guide you through the process of:
- Specifying the IP or DNS name of your primary Pi-hole
- Specifying the SSH username to connect to your primary Pi-hole
- Selecting the SSH authentication mechanism (key-pair or password)
- Configuring your key-pair and applying it to your primary Pi-hole
- Testing your authentication method
After you've completed your configuration, proceed to the Execution phase. Unless you feel like making this (slightly) harder on yourself.
### The Less Easy Way
There will be a file called `gravity-sync.conf.example` that you can use as the basis for your own `gravity-sync.conf` file. Make a copy of the example file and modify it with your site specific settings.
``` ```
cp gravity-sync.conf.example gravity-sync.conf cp gravity-sync.conf.example gravity-sync.conf

If you installed via Option 2, download and overwrite the `gravity-sync.sh` file with a newer version.

The goal of Gravity Sync is to be simple, so any additional requirements should also be called out when it's executed. After updating, be sure to manually run a `./gravity-sync.sh compare` or `./gravity-sync.sh pull` to validate things are still working as expected.

If you are unable to run the `gravity-sync.sh` file, make sure it's marked as an executable by Linux. If you are just straight up unable to run the `gravity-sync.sh` file, make sure it's marked as an executable by Linux.
``` ```

If you'd like to know what version of the script you have running. - If your script prompts for a password on the remote system, make sure that your user account is setup not to require passwords in the sudoers file.
- If you use a non-standard SSH port to connect to your primary Pi-hole, you can add `SSH_PORT='123'` to the bottom of your `gravity-sync.conf` file. (Subsitute 123 for your non-standard port.) This will overwrite the `SSH_PORT=22` at the top of the script as it is imported later in the execution.
- If you'd like to know what version of the script you have running by running `./gravity-sync.sh version`
- If the update script fails, make sure you did your original deployment via `git clone` and not a manual install.
- If it doesn't kick off, you can manually execute a `git pull` while in the `gravity-sync` directory.
```
./gravity-sync.sh version
