Ethereum: How to install Berkeley DB 4.8 under Linux
As a developer who works with Ethereum -Smart Contracts, you have probably found the need to store data in a structured format such as JSON or BINARY. In this article we will guide you on your Linux system through the process of installing Berkeley DB 4.8.
What is Berkeley DB?
The Berkeley database (Berkeley DB) is an open source database management system with which you can save and query structured data in a flexible, self-contained format. It is often used for different applications, including databases, caching and data storage.
Why do I need Berkeley DB 4.8 under Linux?
To install Ethereum, you will probably work with JSON-based data structures or binary files stored in the “Wallet ‘directory”. However, some older versions of Ethereum (before version 1.3) required a certain version of Berkeley DB 4.6 to work properly.
Fortunately, a newer version of Berkeley DB was released: 4.8. We will show you how to install it on your Linux system.
Install Berkeley DB 4.8 under Linux
Ubuntu and Debian (with Libdb DEV packages)
If you use Ubuntu or Debian, you can easily install the required Libdb-Dev package together with Berkeley DB 4.8:
`Bash
Sudo apt-Get Install Libdb-Dev Libdb ++-Dev
After installation, you have to link to the Berkeley DB library for your specific project:
`Bash
g ++ -o example.cpp -i/usr/include/Berkeley -db
Alternative method with docker
You should use dockers for more comfortable and reproducible experience. You can create a Docker image with Berkeley DB 4.8 and install its dependencies:
`Dockerfile
By Ubuntu: Latest
Conduct APT-Get-update && APT-Get Install -Y Libdb-Dev Libdb ++-Dev
Workdir /app
Copy. /App/
CMD [“G ++”, “-O”, “Example”, “Example.cpp”]
`
As soon as the picture has been created, you can pull it and run your project:
`Bash
Docker Pull Berkeley-Db-4.8 image
Docker Run -it Berkeley-Db-4.8-Image example
Install Berkeley DB 4.8 on a non-standard Linux distribution
If you use another Linux distribution (e.g. Fedora, Centos) or not installed the “Libdb-DEV” package, you must install Berkeley DB 4.8 manually:
- Download the source code of Berkeley DB 4.8 from the official website: <
- Extract the ZIP file with
TAR XZF BDB-4.8.TAR.GZZ
- Create a new directory for your project and navigate to IT:
`Bash
Mkdir MyProject
CD MyProject
V.
- Use the following command to build Berkeley DB 4.8:
`
CD BDB-4.8
./Configure -Prefix =/USR/Local/BDB -4.8
make
Install Sudo Mach
`
S.
Now you are ready to use Berkeley DB 4.8 with your Ethereum Smart Contract project!
