SQLite 3 is a self-contained, serverless, and zero-configuration database engine widely used in applications ranging from embedded devices to large-scale web applications. Unlike traditional databases, SQLite stores the entire database in a single file, making it lightweight and easy to deploy. It supports a full range of SQL queries, transactions, and multi-user access while maintaining a small footprint. SQLite 3 is particularly known for its reliability, simplicity, and efficiency, making it a popular choice for developers who need a robust database solution without the overhead of a full-fledged database server.
On Ubuntu 24.04, 22.04, or 20.04, SQLite 3 can be installed using two primary methods. The first method is via the Ubuntu default repository, which provides a stable version of SQLite 3 that is easy to install and integrates well with the system. This version is suitable for most users who need a reliable and well-supported database engine. Alternatively, for those who require the latest features and performance improvements, SQLite 3 can be installed by downloading the source archive, configuring, compiling, and installing the latest SQLite 3 binary. This approach ensures you have access to the most recent developments in SQLite, though it requires more technical steps. This guide will cover both installation methods in detail.
Method 1: Install SQLite 3 via APT
Update Ubuntu Before SQLite 3 Installation
To ensure a smooth installation process and avoid potential conflicts, it is essential to update your Ubuntu system. This process updates all installed packages on your system to their latest available versions. To update your Ubuntu system, run the following command in your terminal:
sudo apt update && sudo apt upgradeBy running this command, you are using the apt package manager to update the package index and upgrade the installed packages to their latest versions.
Install SQLite 3 via APT Commands
The recommended approach for installing SQLite 3 on your Ubuntu system is to use the default APT repository. This method ensures that you install a stable, well-tested version of SQLite 3 that is compatible with your Ubuntu version. To start the installation process, run the following command in your terminal:
sudo apt install sqliteThis command uses the apt package manager to download and install the sqlite package on your system. The package manager handles any required dependencies and ensures that SQLite 3 integrates correctly with your Ubuntu system.
Verify the SQLite 3 Installation
After the installation, it’s essential to verify that SQLite 3 is installed correctly and functioning as expected. To do this, you can check the installed version of SQLite 3 by running the –version command:
sqlite3 --versionThis command will display the installed SQLite 3 version in your terminal, allowing you to confirm that the installation was successful and that you have the desired version of SQLite 3 on your Ubuntu system.
Method 2: Install SQLite 3 via Source Archive
Download the Latest SQLite 3 Archive
If you prefer to compile SQLite 3 from the source, you can obtain the latest or a specific version by visiting the SQLite Download page. This method allows you to have more control over the version you install. First, identify the latest version of SQLite 3 on the download page. Then, use the wget command to download the appropriate archive:
wget https://www.sqlite.org/2023/sqlite-autoconf-{version}.tar.gzReplace {version} with the actual version number. Always check the SQLite Download page for the most recent version.
For example:
wget https://www.sqlite.org/2023/sqlite-autoconf-3410200.tar.gzExtract the SQLite 3 Archive
Once the archive is downloaded, extract the files using the following command:
tar xvfz sqlite-autoconf-*.tar.gzThis command uses the tar utility to extract the compressed archive into a new directory.
Navigate to the Extracted Directory and Configure Prefix
Change the directory to the extracted folder to begin the compilation process:
cd sqlite-autoconf-{replace with version}Replace {version} with the actual version number.
Now, configure the compilation with the desired installation prefix:
./configure --prefix=/usr
Compile SQLite with make Command
To start the build process, use the “make” command along with the -j flag to specify the number of cores you want to utilize for faster compilation:
make -j {number_of_cores}Replace {number_of_cores} with the desired number of cores for your system.
To determine the number of cores on your system, run the following:
nprocFor example, use “make -j 2” if your machine has two cores. If you have 12 cores, you could use “make -j 6” to dedicate half of your cores to the process.
Lastly, if the make command fails as the package is missing, run the following command:
sudo apt install build-essential
Install SQLite 3 on Ubuntu via Compiled Binary
After the build process is complete, install SQLite using the following command:
sudo make installThe installation process will display output indicating the progress. Once installed, verify the installation and the version number:
sqlite3 --version
Conclusion
By installing SQLite 3 on your Ubuntu system, whether through the default repository or by compiling from the source archive, you gain access to a powerful and versatile database engine. The default repository method offers a quick and stable installation, ideal for most users, while compiling from source allows you to leverage the latest features and optimizations. Regular updates, especially if you compile from source, ensure that your SQLite installation remains current, providing a reliable and efficient database solution for your applications on Ubuntu.
