# Installation from binary

All downloads come with SQLite, MySQL and PostgreSQL support, and are built with
embedded assets. This can be different for older releases. Choose the file matching
the destination platform from the [downloads page](https://dl.gitea.io/gitea), copy
the URL and replace the URL within the commands below:

```sh
wget -O gitea https://dl.gitea.io/gitea/1.5.0/gitea-1.5.0-linux-amd64
chmod +x gitea
```

## Verify GPG signature
Gitea signs all binaries with a [GPG key](https://pgp.mit.edu/pks/lookup?op=vindex&fingerprint=on&search=0x2D9AE806EC1592E2) 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.

```sh
gpg --keyserver pgp.mit.edu --recv 7C9E68152594688862D62AF62D9AE806EC1592E2
gpg --verify gitea-1.5.0-linux-amd64.asc gitea-1.5.0-linux-amd64
```

## Test

After getting a binary, it can be tested with `./gitea web` or moved to a permanent
location. When launched manually, Gitea can be killed using `Ctrl+C`.

```
./gitea web
```

## Recommended server configuration

### Prepare environment

Check that git is installed on the server, if it is not install it first.
```sh
git --version
```

Create user to run gitea (ex. `git`)
```sh
adduser \
   --system \
   --shell /bin/bash \
   --gecos 'Git Version Control' \
   --group \
   --disabled-password \
   --home /home/git \
   git
```

### Create required directory structure

```sh
mkdir -p /var/lib/gitea/{custom,data,indexers,public,log}
chown git:git /var/lib/gitea/{data,indexers,log}
chmod 750 /var/lib/gitea/{data,indexers,log}
mkdir /etc/gitea
chown root:git /etc/gitea
chmod 770 /etc/gitea
```

**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:
```
chmod 750 /etc/gitea
chmod 644 /etc/gitea/app.ini
```

### Copy gitea binary to global location

```
cp gitea /usr/local/bin/gitea
```

### Create service file to start gitea automatically

See how to create [Linux service]({{< relref "run-as-service-in-ubuntu.en-us.md" >}})

## Updating to a new version

You can update to a new version of gitea by stopping gitea, replacing the binary at `/usr/local/bin/gitea` and restarting the instance. 
The binary file name should not be changed during the update to avoid problems 
in existing repositories. 

It is recommended you do a [backup]({{< relref "doc/usage/backup-and-restore.en-us.md" >}}) before updating your installation.

If you have carried out the installation steps as described above, the binary should 
have the generic name `gitea`. Do not change this, i.e. to include the version number. 

See below for troubleshooting instructions to repair broken repositories after 
an update of your gitea version.

## Troubleshooting

### Old glibc versions

Older Linux distributions (such as Debian 7 and CentOS 6) may not be able to load the
Gitea binary, usually producing an error such as ```./gitea: /lib/x86_64-linux-gnu/libc.so.6:
version `GLIBC\_2.14' not found (required by ./gitea)```. This is due to the integrated
SQLite support in the binaries provided by dl.gitea.io. In this situation, it is usually
possible to [install from source]({{< relref "from-source.en-us.md" >}}) without sqlite
support.

### Running gitea on another port

For errors like `702 runWeb()] [E] Failed to start server: listen tcp 0.0.0.0:3000:
bind: address already in use` gitea needs to be started on another free port. This
is possible using `./gitea web -p $PORT`. It's possible another instance of gitea
is already running.

### Git error after updating to a new version of gitea

If the binary file name has been changed during the update to a new version of gitea, 
git hooks in existing repositories will not work any more. In that case, a git 
error will be displayed when pushing to the repository.

```
remote: ./hooks/pre-receive.d/gitea: line 2: [...]: No such file or directory
```

The `[...]` part of the error message will contain the path to your previous gitea 
binary.

To solve this, go to the admin options and run the task `Resynchronize pre-receive, 
update and post-receive hooks of all repositories` to update all hooks to contain
the new binary path. Please note that this overwrite all git hooks including ones
with customizations made.

If you aren't using the built-in to Gitea ssh server you will also need to re-write
the authorized key file by running the `Update the '.ssh/authorized_keys' file with
Gitea SSH keys.` task in the admin options.
