Gitea signs all binaries with a [GPG key](https://keys.openpgp.org/search?q=teabot%40gitea.io) to prevent against unwanted modification of binaries. To validate the binary, download the signature file which ends in `.asc` for the binary you downloaded and use the gpg command line tool.
**NOTE:** Many of the following directories can be configured using [Environment Variables]({{< relref "doc/advanced/environment-variables.en-us.md" >}}) as well!
**NOTE:** `/etc/gitea` is temporary set with write rights for user `git` so that Web installer could write configuration file. After installation is done, it is recommended to set rights to read-only using:
If you don't want the web installer to be able to write the config file at all, it is also possible to make the config file read-only for the gitea user (owner/group `root:root`, mode `0660`), and set `INSTALL_LOCK = true`. In that case all database configuration details must be set beforehand in the config file, as well as the `SECRET_KEY` and `INTERNAL_TOKEN` values. See the [command line documentation]({{< relref "doc/usage/command-line.en-us.md" >}}) for information on using `gitea generate secret INTERNAL_TOKEN`.
**NOTE:** If you plan on running Gitea as a Linux service, you can skip this step as the service file allows you to set `WorkingDirectory`. Otherwise, consider setting this environment variable (semi-)permanently so that Gitea consistently uses the correct working directory.
### 1. Restarting gitea with systemd (recommended)
As explained before, we recommend to use systemd as service manager. In this case ```systemctl restart gitea``` should be enough.
### 2. Restarting gitea without systemd
To restart your gitea instance, we recommend to use SIGHUP signal. If you know your gitea PID use ```kill -1 $GITEA_PID``` otherwise you can use ```killall -1 gitea``` or ```pkill -1 gitea```
To gracefully stop the gitea instance, a simple ```kill $GITEA_PID``` or ```killall gitea``` is enough.
**NOTE:** We don't recommend to use SIGKILL signal (know also as `-9`), you may be forcefully stopping some of Gitea internal tasks and it will not gracefully stop (tasks in queues, indexers processes, etc.)
