This document describes how to install TDengine on Linux and Windows and perform queries and inserts.

- The easiest way to explore TDengine is through [TDengine Cloud](http://cloud.tdengine.com). 
- To get started with TDengine on Docker, see [Quick Install on Docker](../../get-started/docker).
- If you want to view the source code, build TDengine yourself, or contribute to the project, see the [TDengine GitHub repository](https://github.com/taosdata/TDengine).

The full package of TDengine includes the TDengine Server (`taosd`), TDengine Client (`taosc`), taosAdapter for connecting with third-party systems and providing a RESTful interface, a command-line interface (CLI, taos), and some tools. Note that taosAdapter supports Linux only. In addition to connectors for multiple languages, TDengine also provides a [REST API](../../reference/rest-api) through [taosAdapter](../../reference/taosadapter).

The standard server installation package includes `taos`, `taosd`, `taosAdapter`, `taosBenchmark`, and sample code. You can also download the Lite package that includes only `taosd` and the C/C++ connector.

The TDengine Community Edition is released as Deb and RPM packages. The Deb package can be installed on Debian, Ubuntu, and derivative systems. The RPM package can be installed on CentOS, RHEL, SUSE, and derivative systems. A .tar.gz package is also provided for enterprise customers, and you can install TDengine over `apt-get` as well. The .tar.tz package includes `taosdump` and the TDinsight installation script. If you want to use these utilities with the Deb or RPM package, download and install taosTools separately. TDengine can also be installed on 64-bit Windows.

## Quick Launch

<Tabs>
<TabItem label="Linux" value="linux">

After the installation is complete, run the following command to start the TDengine service:

```bash
systemctl start taosd
```

Run the following command to confirm that TDengine is running normally:

```bash
systemctl status taosd
```

Output similar to the following indicates that TDengine is running normally:

```
Active: active (running)
```

Output similar to the following indicates that TDengine has not started successfully:

```
Active: inactive (dead)
```

After confirming that TDengine is running, run the `taos` command to access the TDengine CLI.

The following `systemctl` commands can help you manage TDengine service:

- Start TDengine Server: `systemctl start taosd`

- Stop TDengine Server: `systemctl stop taosd`

- Restart TDengine Server: `systemctl restart taosd`

- Check TDengine Server status: `systemctl status taosd`

:::info

- The `systemctl` command requires _root_ privileges. If you are not logged in as the _root_ user, use the `sudo` command.
- The `systemctl stop taosd` command does not instantly stop TDengine Server. The server is stopped only after all data in memory is flushed to disk. The time required depends on the cache size.
- If your system does not include `systemd`, you can run `/usr/local/taos/bin/taosd` to start TDengine manually.

<TabItem label="Windows" value="windows">

After the installation is complete, run `C:\TDengine\taosd.exe` to start TDengine Server.

</Tabs>

## Command Line Interface (CLI)

You can use the TDengine CLI to monitor your TDengine deployment and execute ad hoc queries. To open the CLI, you can execute `taos` in the Linux terminal where TDengine is installed, or you can run `taos.exe` in the `C:\TDengine` directory of the Windows terminal where TDengine is installed to start the TDengine command line.

```bash
taos
```

The TDengine CLI displays a welcome message and version information to indicate that its connection to the TDengine service was successful. If an error message is displayed, see the [FAQ](/train-faq/faq) for troubleshooting information. At the following prompt, you can execute SQL commands.

```cmd
taos>
```

For example, you can create and delete databases and tables and run all types of queries. Each SQL command must be end with a semicolon (;). For example:

```sql
CREATE DATABASE demo;
USE demo;
CREATE TABLE t (ts TIMESTAMP, speed INT);
INSERT INTO t VALUES ('2019-07-15 00:00:00', 10);
INSERT INTO t VALUES ('2019-07-15 01:00:00', 20);
SELECT * FROM t;

           ts            |    speed    |
========================================
 2019-07-15 00:00:00.000 |          10 |
 2019-07-15 01:00:00.000 |          20 |

Query OK, 2 row(s) in set (0.003128s)
```

You can also can monitor the deployment status, add and remove user accounts, and manage running instances. You can run the TDengine CLI on either Linux or Windows machines. For more information, see [TDengine CLI](../../reference/taos-shell/).

## Test data insert performance

After your TDengine Server is running normally, you can run the taosBenchmark utility to test its performance:

Start TDengine service and execute `taosBenchmark` (formerly named `taosdemo`) in a Linux or Windows terminal.

```bash
taosBenchmark
```

This command creates the `meters` supertable in the `test` database. In the `meters` supertable, it then creates 10,000 subtables named `d0` to `d9999`. Each table has 10,000 rows and each row has four columns: `ts`, `current`, `voltage`, and `phase`. The timestamps of the data in these columns range from 2017-07-14 10:40:00 000 to 2017-07-14 10:40:09 999. Each table is randomly assigned a `groupId` tag from 1 to 10 and a `location` tag of either `California.Campbell`, `California.Cupertino`, `California.LosAngeles`, `California.MountainView`, `California.PaloAlto`, `California.SanDiego`, `California.SanFrancisco`, `California.SanJose`, `California.SantaClara` or `California.Sunnyvale`.

The `taosBenchmark` command creates a deployment with 100 million data points that you can use for testing purposes. The time required to create the deployment depends on your hardware. On most modern servers, the deployment is created in ten to twenty seconds.

You can customize the test deployment that taosBenchmark creates by specifying command-line parameters. For information about command-line parameters, run the `taosBenchmark --help` command. For more information about taosBenchmark, see [taosBenchmark](../../reference/taosbenchmark).

## Test data query performance

After using `taosBenchmark` to create your test deployment, you can run queries in the TDengine CLI to test its performance:

From the TDengine CLI (taos) query the number of rows in the `meters` supertable:

```sql
SELECT COUNT(*) FROM test.meters;
```

Query the average, maximum, and minimum values of all 100 million rows of data:

```sql
SELECT AVG(current), MAX(voltage), MIN(phase) FROM test.meters;
```

Query the number of rows whose `location` tag is `California.SanFrancisco`:

```sql
SELECT COUNT(*) FROM test.meters WHERE location = "California.SanFrancisco";
```

Query the average, maximum, and minimum values of all rows whose `groupId` tag is `10`:

```sql
SELECT AVG(current), MAX(voltage), MIN(phase) FROM test.meters WHERE groupId = 10;
```

Query the average, maximum, and minimum values for table `d10` in 10 second intervals:

```sql
SELECT FIRST(ts), AVG(current), MAX(voltage), MIN(phase) FROM test.d10 INTERVAL(10s);
```

In the query above you are selecting the first timestamp (ts) in the interval, another way of selecting this would be `\_wstart` which will give the start of the time window. For more information about windowed queries, see [Time-Series Extensions](../../taos-sql/distinguished/).
