+This tool can run as a test client with the following features:
+
+1. Any number of concurrent threads
+1. Any number of test steps/loops
+1. Auto-create and writing to multiple databases
+1. Ignore specific error codes
+1. Write small or large data blocks
+1. Auto-generate out-of-sequence data, if needed
+1. Verify the result of write operations
+1. Concurrent writing to a shadow database for later data verification
+1. User specified number of replicas to use, against clusters
+
+This tool can also use to start a TDengine service, either in stand-alone mode or 
+cluster mode. The features include:
+
+1. User specified number of D-Nodes to create/use.

+# 通过Docker快速体验TDengine
+
+由于目前TDengine2.0的服务器仅能在Linux系统上安装和运行，如果开发者使用的是Mac或Windows系统，可能需要安装虚拟机或远程连接Linux服务器，来使用TDengine。Docker轻巧快速，可以作为一个可行，经济，高效的替代方案。下文准备一步一步介绍，如何通过Docker快速使用TDengine，可用于开发，测试，和备份数据。
+
+&nbsp; 
+### 下载Docker
+
+docker的下载可以参考[docker官网文档Get Docker部分](https://docs.docker.com/get-docker/)。
+
+安装成功后可以查看下docker版本。
+
+```bash
+$ docker -v
+Docker version 20.10.5, build 55c4c88
+```
+
+&nbsp; 
+&nbsp; 
+### 在docker容器中运行TDengine
+
++ 使用命令拉取tdengine镜像，并使它在后台运行。
+
+```bash
+$ docker run -d tdengine/tdengine
+cdf548465318c6fc2ad97813f89cc60006393392401cae58a27b15ca9171f316
+```
+
+&emsp;&emsp;**run**：和前面的docker命令组合起来，运行一个容器。
+
+&emsp;&emsp;**-d**：让容器在后台运行。
+
+&emsp;&emsp;**tdengine/tdengine**：拉取的TDengine官方发布的应用镜像
+
+&emsp;&emsp;**cdf548465318c6fc2ad97813f89cc60006393392401cae58a27b15ca9171f316**：
+
+&emsp;&emsp;返回的长字符是容器ID，我们可以通过容器ID来查看对应的容器。
+
+&nbsp; 
++ 确认容器是否已经运行起来了。
+
+```bash
+$ docker ps
+CONTAINER ID   IMAGE               COMMAND   CREATED          STATUS          ···
+cdf548465318   tdengine/tdengine   "taosd"   14 minutes ago   Up 14 minutes   ···
+```
+
+&emsp;&emsp;**docker ps**：列出所有在运行中的容器信息。
+
+&emsp;&emsp;**CONTAINER ID**：容器ID。
+
+&emsp;&emsp;**IMAGE**：使用的镜像。
+
+&emsp;&emsp;**COMMAND**：启动容器时运行的命令。
+
+&emsp;&emsp;**CREATED**：容器创建时间。
+
+&emsp;&emsp;**STATUS**：容器状态。UP表示运行中。
+
+&nbsp; 
++ 进入docker容器内，使用tdengine。
+
+```bash
+$ docker exec -it cdf548465318 /bin/bash
+root@cdf548465318:~/TDengine-server-2.0.13.0#
+```
+
+&emsp;&emsp;**exec**：通过docker exec命令进入容器，如果退出容器不会停止。
+
+&emsp;&emsp;**-i**：进入交互模式。
+
+&emsp;&emsp;**-t**：指定一个终端。
+
+&emsp;&emsp;**cdf548465318**：容器ID，需要根据具体情况进行修改。
+
+&emsp;&emsp;**/bin/bash**：载入容器后运行bash来进行交互。
+
+&nbsp; 
++ 进入容器后，执行TDengine命令行程序。
+
+```bash
+$ root@cdf548465318:~/TDengine-server-2.0.13.0# taos
+
+Welcome to the TDengine shell from Linux, Client Version:2.0.13.0
+Copyright (c) 2020 by TAOS Data, Inc. All rights reserved.
+
+taos>
+```
+
+TDengine终端连接服务成功，打印出了欢迎消息和版本信息。如果失败，会有错误信息打印出来。
+
+在TDengine终端中，可以通过SQL命令来创建/删除数据库，表，超级表等，并可以进行插入查询操作。具体可以参考[TDengine官网文档的TAOS SQL部分](https://www.taosdata.com/cn/documentation/taos-sql)。
+
+&nbsp; 
+&nbsp; 
+### 通过taosdemo进一步了解TDengine
+
++ 接上面的步骤，先退出TDengine命令行程序。
+
+```bash
+$ taos> q
+root@cdf548465318:~/TDengine-server-2.0.13.0#
+```
+
+&nbsp; 
++ 在Linux终端执行taosdemo。
+
+```bash
+$ root@cdf548465318:~/TDengine-server-2.0.13.0# taosdemo
+###################################################################

+# Test time:                         2021-04-13 02:05:20
+###################################################################
+```
+
+回车后，该命令将新建一个数据库test，并且自动创建一张超级表meters，并以超级表meters为模版创建了1万张表，表名从"t0"到"t9999"。每张表有10万条记录，每条记录有f1，f2，f3三个字段，时间戳ts字段从"2017-07-14 10:40:00 000" 到"2017-07-14 10:41:39 999"。每张表带有areaid和loc两个标签TAG， areaid被设置为1到10, loc被设置为"beijing"或者“shanghai"。
+
+&nbsp; 
++ 运行taodemo命令的结果，可以进入TDengine命令行，进行验证。
+
+&emsp;&emsp;**进入命令行。**
+
+```bash
+$ root@cdf548465318:~/TDengine-server-2.0.13.0# taos

+

+===========================
+          10 | shanghai   |
+Query OK, 1 row(s) in set (0.002904s)
+
+```
+
+&nbsp; 
+&nbsp; 
+### 开发时连接上通过docker启动的TDengine
+
+连接并且使用在docker容器中的启动的TDengine，有以下两个思路：
+
+
+1. 通过端口映射(-p)，将容器内部开放的网络端口映射到宿主机的指定端口上。通过挂载本地目录(-v)，可以实现宿主机与容器内部的数据同步，防止容器删除后，数据丢失。
+
+```bash
+$ docker run -d -v /etc/taos:/etc/taos -p 6041:6041 tdengine/tdengine
+526aa188da767ae94b244226a2b2eec2b5f17dd8eff592893d9ec0cd0f3a1ccd
+
+$ curl -u root:taosdata -d 'show databases' 127.0.0.1:6041/rest/sql
+{"status":"succ","head":["name","created_time","ntables","vgroups","replica","quorum","days","keep1,keep2,keep(D)","cache(MB)","blocks","minrows","maxrows","wallevel","fsync","comp","precision","status"],"data":[],"rows":0}
+```
+
+&emsp;&emsp;第一条命令，启动了一个运行了TDengine的docker容器，并且将容器的6041端口映射到宿主机的6041端口上。
+
+&emsp;&emsp;第二条命令，通过RESTful接口访问TDengine，这时连接的是本机的6041端口，可见连接成功。
+
+&nbsp; 
+2. 直接通过exec命令，进入到docker容器中去做开发。
+
+```bash
+$ docker exec -it 526aa188da /bin/bash
+```
+

-# 通过Docker快速体验TDengine
+# 通过 Docker 快速体验 TDengine
 
-由于目前TDengine2.0的服务器仅能在Linux系统上安装和运行，如果开发者使用的是Mac或Windows系统，可能需要安装虚拟机或远程连接Linux服务器，来使用TDengine。Docker轻巧快速，可以作为一个可行，经济，高效的替代方案。下文准备一步一步介绍，如何通过Docker快速使用TDengine，可用于开发，测试，和备份数据。
+虽然并不推荐在生产环境中通过 Docker 来部署 TDengine 服务，但 Docker 工具能够很好地屏蔽底层操作系统的环境差异，很适合在开发测试或初次体验时用于安装运行 TDengine 的工具集。特别是，借助 Docker，能够比较方便地在 Mac OSX 和 Windows 系统上尝试 TDengine，而无需安装虚拟机或额外租用 Linux 服务器。

-### 下载Docker
+下文通过 Step by Step 风格的介绍，讲解如何通过 Docker 快速建立 TDengine 的单节点运行环境，以支持开发和测试。

+## 下载 Docker
 
-安装成功后可以查看下docker版本。
+Docker 工具自身的下载请参考 [Docker官网文档](https://docs.docker.com/get-docker/)。

Subject: [PATCH 169/185] [TD-3204]<fix>: support usigned integer types for C#
 connector (#5808)

Added unsigned integer types and change taosdemo insert and select queries for these types.

taos define | taos sql | c#
--- | --- | ---
UTINYINT | TINYINT UNSIGNED | `byte`
USMALLINT | SMALLINT UNSIGNED | `ushort`
UINT | INT UNSIGNED | `uint`
UBIGINT | BIGINT UNSIGNED | `ulong`
TINYINT | TINYINT | `sbyte`

Note: also change the tinyint value type to C# `sbyte`(the right signed one byte type) in this pr.

 **FQDN配置**：一个数据节点有一个或多个FQDN，可以在系统配置文件taos.cfg通过参数“fqdn"进行指定，如果没有指定，系统将自动获取计算机的hostname作为其FQDN。如果节点没有配置FQDN，可以直接将该节点的配置参数fqdn设置为它的IP地址。但不建议使用IP，因为IP地址可变，一旦变化，将让集群无法正常工作。一个数据节点的EP(End Point)由FQDN + Port组成。采用FQDN，需要保证DNS服务正常工作，或者在节点以及应用所在的节点配置好hosts文件。
 
-**端口配置：**一个数据节点对外的端口由TDengine的系统配置参数serverPort决定，对集群内部通讯的端口是serverPort+5。集群内数据节点之间的数据复制操作还占有一个TCP端口，是serverPort+10. 为支持多线程高效的处理UDP数据，每个对内和对外的UDP连接，都需要占用5个连续的端口。因此一个数据节点总的端口范围为serverPort到serverPort + 10，总共11个TCP/UDP端口。（另外还可能有 RESTful、Arbitrator 所使用的端口，那样的话就一共是 13 个。）使用时，需要确保防火墙将这些端口打开，以备使用。每个数据节点可以配置不同的serverPort。

 参数`taos`是一个已经建立好的数据库连接，在同步模式下无特殊要求。但在异步模式下，需要注意它不会被其它线程使用，否则可能导致不可预计的错误，因为回调函数在API的内部线程中被调用，而TDengine的部分API不是线程安全的。
