windows上安裝TDengine-client和配置

客戶端版本要和服務端版本保持一致。下載地址：https://www.taosdata.com/all-downloads

 

1.修改客戶端的hosts

修改client的hosts文件（C:\Windows\System32\drivers\etc\hosts），將server的hostname和ip配置到client的hosts文件中

 

 

 

 格式：IP hostname

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#    127.0.0.1       localhost
#    ::1             localhost

#0.0.0.0 account.jetbrains.com
0.0.0.0 www.jetbrains.com
0.0.0.0 activate.navicat.com
0.0.0.0 account.jetbrains.com
127.0.0.1 eureka7001.com
127.0.0.1 eureka7002.com
192.144.215.114 VM_0_14_centos

2.修改TDengine的taos.cfg配置文件（保持默認也可以）

可以保持默認配置，默認是不啟動 firstEp和fqdn。如果要啟動放開注釋，hostname的名命要和服務器的hostname一樣。否則后期查詢語句會有問題。比如 我這里服務器的hostname是VM_0_14_centos（利用命令修改）。所以客戶端也的使用VM_0_14_centos

3.開啟服務器 6030-6042的tcp和udp端口(重點)

這里我用的是雲服務器，在雲服務器的安全組開啟端口后，利用Taos Shell並沒有連接成功！

經過幾天的研究，后來在官方文檔中的一句話提醒了我！

 

 我的雲服務是CentO S系統，利用軟件得到結果

3.1 查看當前防火牆端口開啟列表

firewall-cmd --list-port

 

 防火牆端口沒有6030-6042端口。

3.2 批量添加端口

firewall-cmd --zone=public --add-port=6030-6042/tcp --permanent

firewall-cmd --zone=public --add-port=6030-6042/udp --permanent

3.3 重啟防火牆

firewall-cmd --reload

3.4 重新查看端口列表

firewall-cmd --list-port

 

 注意：tcp和udp的6030-6040端口都需要開放。

4.客戶端測試
