Shulou(Shulou.com)06/03 Report--

TDengine of Taosi data is the Internet of things big data platform developed by founder Jefft. According to the official https://www.taosdata.com/cn/ description, it is not difficult to see that another great power artifact has emerged in the circle. Coincidentally, as a veteran who has passively rolled around the battlefield in various technology fields for many years, he has another opportunity to get close to the Internet of things project. Seeing TDengine, he can't help talking about teenage madness, itching, walking and coarse hair:

1. TDengine only supports installation on linux systems that use systemd for process service management.

Just applied for an ECS, centos7 from Aliyun.

# which systemd

The systemd command is not supported; it can only be installed in source code.

two。 Download the source code

Enter https://github.com/taosdata/TDengine to download the source code

3. Install the compilation environment

# yum install-y gcc gcc-c++ make automake

# yum-y install cmake

4. The installation java document says: To compile and package the JDBC driver source code, you should have a Java jdk-8 or higher and Apache Maven 2.7 or higher installed. To install openjdk-8 on Ubuntu

I don't use java, but... We have to find sadly that most of the time, we have to bow to the world.

# yum-y install java-1.8.0-openjdk java-1.8.0-openjdk-devel

Reinstall maven

# wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo-O / etc/yum.repos.d/epel-apache-maven.repo

5. Compile and install TDengine

Go to the root directory of the source code you just downloaded

# cd TDengine-master

Set up the build directory:

TDengine-master] # mkdir build & & cd build

Compile:

# cmake.. & & cmake-- build.

Wait for the compilation to be completed

Another build directory was found in the TDengine-master/build directory
