Automatic Restart Apache2 When It Goes Down

Managing the availability of your Apache2 web server is crucial to ensure uninterrupted web services. In the event that Apache2 unexpectedly stops, whether due to system issues or other reasons, it's essential to have a mechanism in place to automatically restart it. This guide will walk you through the process of creating a shell script and setting up a Systemd service that monitors Apache2's status and automatically restarts it if it's not running. These instructions are applicable to Ubuntu, Debian, and CentOS Linux distributions.

Follow the step-by-step instructions below to create an automated Apache2 restart system on your Ubuntu, Debian, or CentOS server:

Step 1: Login to the Terminal

Access your server's terminal by logging in as a superuser (root) with the following commands:

sudo su

You'll be prompted for your system password (Enter with your System password).

Step 2: Create a Shell Script to Restart Apache2

Create a shell script named `restart_apache.sh` and open it for editing:

nano /usr/local/bin/restart_apache.sh

Add the following content to the file:

#!/bin/bash

while true; do

    if ! systemctl is-active --quiet apache2; then

        echo "Apache2 is not running. Restarting..."

        systemctl restart apache2

    fi

    sleep 5

done

Save the file and exit the text editor.

Step 3: Make the Script Executable

Make the script executable with the following command:

chmod +x /usr/local/bin/restart_apache.sh

Step 4: Create a Systemd Service

Create a Systemd service file named `apache_restart.service` and open it for editing:

nano /etc/systemd/system/apache_restart.service

Add the following content to the file:

[Unit]

Description=Apache2 Restart Service

After=network.target

[Service]

ExecStart=/usr/local/bin/restart_apache.sh

Restart=always

User=root

Group=root

[Install]

WantedBy=multi-user.target

Save the file and exit the text editor.

Step 5: Enable and Start the Service

Enable the newly created service and start it:

sudo systemctl enable apache_restart.service

sudo systemctl start apache_restart.service

With these instructions, you will have established an automatic Apache2 restart mechanism on your Ubuntu, Debian, or CentOS server. This ensures that Apache2 automatically restarts if it unexpectedly stops, maintaining uninterrupted web server operations.
