# Install by DEB Package v5 (Debian/Ubuntu)

This article explains how to install stable versions of `fluent-package` deb packages, the stable Fluentd distribution packages maintained by [Fluentd Project](https://www.fluentd.org/).

## What is `fluent-package`?

Please see [fluent-package-v5-vs-td-agent](/quickstart/fluent-package-v5-vs-td-agent.md).

## How to install `fluent-package`

{% hint style="info" %}
NOTE:

* If you upgrade from `td-agent` v4, See [Upgrade to fluent-package v5](https://www.fluentd.org/blog/upgrade-td-agent-v4-to-v5).
* Do not directly upgrade from v3 to v5. Such a workflow is not supported. It causes a trouble. Upgrade in stages. (v3 to v4, then v4 to v5)
  {% endhint %}

{% hint style="danger" %}
The following are deprecated fluent-package and td-agent (EOL) information:

* As [Drop schedule announcement about EOL of Fluent Package v5](https://www.fluentd.org/blog/schedule-for-fluent-package-5-eol), recommend to upgrade to Fluent Package v6. See [Upgrade Guide for fluent-package v6](https://www.fluentd.org/blog/upgrade-guide-for-fluent-package-v6).
* About [Treasure Agent (td-agent) v4 (EOL)](https://www.fluentd.org/blog/schedule-for-td-agent-4-eol), See [Install by DEB Package v4](/installation/obsolete-installation/treasure-agent-v4-eol-installation/install-by-deb-td-agent-v4.md).
* About [Treasure Agent (td-agent) 3 will not be maintained anymore](https://www.fluentd.org/blog/schedule-for-td-agent-3-eol), see [Install by DEB Package v3](/installation/obsolete-installation/treasure-agent-v3-eol-installation/install-by-deb-td-agent-v3.md).
  {% endhint %}

### Step 0: Before Installation

Please follow the [Pre-installation Guide](/installation/before-install.md) to configure your OS properly.

### Step 1: Install from Apt Repository

NOTE: If your OS is not supported, consider [gem installation](/installation/install-by-gem.md) instead.

A shell script is provided to automate the installation process for each version. The shell script registers a new apt repository at `/etc/apt/sources.list.d/fluent.sources` (or `/etc/apt/sources.list.d/fluent-lts.sources`) and installs the `fluent-package` deb package.

#### For Ubuntu Noble:

**fluent-package 5 (LTS)**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-ubuntu-noble-fluent-package5-lts.sh | sh
```

**fluent-package 5**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-ubuntu-noble-fluent-package5.sh | sh
```

#### For Ubuntu Jammy:

**fluent-package 5 (LTS)**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-ubuntu-jammy-fluent-package5-lts.sh | sh
```

**fluent-package 5**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-ubuntu-jammy-fluent-package5.sh | sh
```

#### For Ubuntu Focal:

{% hint style="info" %}
fluent-package v6 will not be shipped for Ubuntu Focal.
{% endhint %}

**fluent-package 5 (LTS)**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-ubuntu-focal-fluent-package5-lts.sh | sh
```

**fluent-package 5**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-ubuntu-focal-fluent-package5.sh | sh
```

#### For Debian Bookworm:

**fluent-package 5 (LTS)**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-debian-bookworm-fluent-package5-lts.sh | sh
```

**fluent-package 5**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-debian-bookworm-fluent-package5.sh | sh
```

#### For Debian Bullseye:

{% hint style="info" %}
fluent-package v6 will not be shipped for Debian Bullseye.
{% endhint %}

**fluent-package 5 (LTS)**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-debian-bullseye-fluent-package5-lts.sh | sh
```

**fluent-package 5**

```bash
curl -fsSL https://fluentd.cdn.cncf.io/sh/install-debian-bullseye-fluent-package5.sh | sh
```

### Step 2: Launch Daemon

### `systemd`

Use `/lib/systemd/system/fluentd` script to `start`, `stop`, or `restart` the agent:

```
$ sudo systemctl start fluentd.service
$ sudo systemctl status fluentd.service
 sudo systemctl status fluentd
● fluentd.service - fluentd: All in one package of Fluentd
     Loaded: loaded (/lib/systemd/system/fluentd.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2023-08-16 08:18:22 UTC; 18s ago
       Docs: https://docs.fluentd.org/
    Process: 494 ExecStart=/opt/fluent/bin/fluentd --log $FLUENT_PACKAGE_LOG_FILE --daemon /var/run/fluent/fluentd.pid $FLUENT_PACKAGE_OPTI>
   Main PID: 826 (fluentd)
      Tasks: 9 (limit: 4660)
     Memory: 95.4M
        CPU: 731ms
     CGroup: /system.slice/fluentd.service
             ├─826 /opt/fluent/bin/ruby /opt/fluent/bin/fluentd --log /var/log/fluent/fluentd.log --daemon /var/run/fluent/fluentd.pid
             └─833 /opt/fluent/bin/ruby -Eascii-8bit:ascii-8bit /opt/fluent/bin/fluentd --log /var/log/fluent/fluentd.log --daemon /var/run>
```

To customize `systemd` behavior, put your `fluentd.service` in `/etc/systemd/system`.

NOTE: In fluent-package v5, path is different. `/opt/fluent/bin` instead of `/opt/td-agent/bin`

### Step 3: Post Sample Logs via HTTP

The default configuration (`/etc/fluent/fluentd.conf`) is to receive logs at an HTTP endpoint and route them to `stdout`. For `fluent-package` logs, see `/var/log/fluent/fluentd.log`.

You can post sample log records with `curl` command:

```
$ curl -X POST -d 'json={"json":"message"}' http://localhost:8888/debug.test
$ tail -n 1 /var/log/fluent/fluentd.log
2018-01-01 17:51:47 -0700 debug.test: {"json":"message"}
```

## Next Steps

You are now ready to collect real logs with Fluentd. Refer to the following tutorials on how to collect data from various sources:

* Basic Configuration
  * [Config File](/configuration/config-file.md)
* Application Logs
  * [Ruby](/language-bindings/ruby.md), [Java](/language-bindings/java.md), [Python](/language-bindings/python.md), [PHP](/language-bindings/php.md),
