Install SQLite 3 on Fedora Linux via DNF
Step 1: Update Fedora Linux Before SQLite 3 Installation
Before installing SQLite, ensuring your Fedora Linux system is up-to-date is essential. Updating the system helps to avoid potential conflicts or issues during the SQLite installation process. To update your Fedora Linux system, open a terminal and execute the following command:
sudo dnf upgrade --refresh
This command ensures that your system’s packages are updated to their latest versions, while the --refresh
flag forces a refresh of the repository metadata.
Step 2: Install SQLite 3 via DNF Command
The recommended method for installing SQLite 3 on Fedora Linux is to use the default appstream provided by Fedora’s repository. The appstream contains the latest stable version of SQLite 3, which has been tested for compatibility with Fedora.
To install SQLite 3, run the following command in your terminal:
sudo dnf install sqlite3
This command instructs the package manager (DNF) to install SQLite 3 from Fedora’s repository. Once the installation is complete, verifying the installed version of SQLite 3 is a good practice to ensure you have the correct version.
To check the version of SQLite 3, execute the following command:
sqlite3 --version
This command displays the installed SQLite 3 version, which should match the latest stable release in Fedora’s repository.
Install SQLite 3 on Fedora Linux via source
Step 1: Download the Latest SQLite 3 Archive on Fedora
To obtain the latest or preferred version of SQLite 3, you may compile it from the source. First, visit the SQLite Download page and identify the latest version. Then, use the wget
command to download the appropriate archive.
wget https://www.sqlite.org/2023/sqlite-autoconf-{version}.tar.gz
Replace
{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.gz
Step 2: Extract the SQLite Archive
Once the archive is downloaded, extract the files using the following command:
tar xvfz sqlite-autoconf-*.tar.gz
Step 3: 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
The output should resemble the following:
configure: creating ./config.status
config.status: creating Makefile
config.status: creating sqlite3.pc
config.status: executing depfiles commands
config.status: executing libtool commands
Step 4: Compile SQLite with the 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:
nproc
For example, if your machine has two cores, use make -j 2
. If you have 12 cores, you could use make -j 6
to dedicate half of your cores to the process.
Step 5: Install Compiled SQLite 3 Binary on Fedora
After the build process is complete, install SQLite using the following command:
sudo make install
The installation process will display output indicating the progress. Once installed, verify the installation and the version number:
sqlite3 --version
Following these steps, you have successfully compiled and installed the latest or preferred version of SQLite 3 from the source.
Testing SQLite 3 Installation on Fedora Linux
After installing SQLite 3, it’s essential to test its functionality to ensure it works as expected. This section provides step-by-step instructions to test SQLite 3 by creating a sample database, adding a table, inserting data, and querying the data.
Step 1: Create a Sample SQLite 3 Database on Fedora
First, let’s create a sample database named testdb
using the following command:
sqlite3 testdb.db
This command creates a new SQLite database file called testdb.db
in your current working directory.
Step 2: Create a Sample SQLite 3 Table on Fedora
Now, let’s create a sample table named employees
with the following columns: id
, name
, and position
. Enter the SQLite shell by running:
sqlite3 testdb.db
Once inside the SQLite shell, execute the following SQL command to create the employees
table:
CREATE TABLE employees (id INTEGER PRIMARY KEY, name TEXT, position TEXT);
Press Enter
to execute the command, you should see no output if the table is created successfully.
Step 3: Insert Sample Data with SQLite 3 on Fedora
Next, insert sample data into the employees
table using the following SQL commands:
INSERT INTO employees (name, position) VALUES ('John Doe', 'Manager');
INSERT INTO employees (name, position) VALUES ('Jane Smith', 'Developer');
INSERT INTO employees (name, position) VALUES ('Alice Johnson', 'Designer');
These commands insert three rows into the employees
table with different names and positions.
Step 4: Query the Data with SQLite 3 on Fedora
To confirm that the data has been successfully inserted, run a SELECT query to retrieve the information from the employees
table:
SELECT * FROM employees;
You should see the following output, which displays the data stored in the employees
table:
1|John Doe|Manager 2|Jane Smith|Developer 3|Alice Johnson|Designer
Step 5: Exit the SQLite Shell with SQLite 3 on Fedora
Once you have finished testing, exit the SQLite shell by typing:
.exit
This command returns you to your regular terminal.
Configure SELinux for SQLite 3 on Fedora Linux
SELinux (Security-Enhanced Linux) is a security module that enforces mandatory access control policies on Linux systems. If SELinux is enabled on your system, you may need to configure it to work with SQLite. This section provides step-by-step instructions to configure SELinux for SQLite, ensuring proper access control and security.
Step 1: Check the SELinux Status on Fedora
Before making any changes, verifying whether SELinux is enabled on your system is essential. To check the status of SELinux, run the following command:
sestatus
If SELinux is disabled, you don’t need to perform any further actions. If it’s enabled, proceed to the next step.
Step 2: Set the Appropriate SELinux Context for SQLite 3 on Fedora
SQLite stores its data in database files, usually with a .db
extension. To allow SQLite to access these files, you must set the appropriate SELinux context for them. The httpd_sys_content_t
context is typically used for web server content, so we’ll use that for our SQLite database file.
First, locate your SQLite database file. For this example, we’ll assume it’s located at /var/www/html/testdb.db
. Replace the path with the actual location of your SQLite database file.
Next, run the following command to set the SELinux context for the database file:
sudo chcon -t httpd_sys_content_t /var/www/html/testdb.db
This command sets the SELinux context of the testdb.db
file to httpd_sys_content_t
, allowing SQLite to access the file under the web server context.
Step 3: Verify the SELinux Context
To confirm that the context has been changed successfully, use the ls
command with the -Z
option:
ls -lZ /var/www/html/testdb.db
The output should show the updated SELinux context for the database file:
-rw-r--r--. root root unconfined_u:object_r:httpd_sys_content_t:s0 /var/www/html/testdb.db
The httpd_sys_content_t
context in the output indicates that the context has been set correctly.
Step 4: Test SQLite 3 Access on Fedora
Now that you’ve configured SELinux for SQLite, it’s essential to test whether SQLite can access the database file. If you’re using SQLite with a web application, try accessing the application and performing some database-related tasks, such as creating a new entry, updating existing data, or deleting an entry.
If the application works as expected and can interact with the SQLite database without issues, the SELinux configuration for SQLite is successful.
