Restart Lamp Server AWS: Everything You Need to Know

Introduction

Welcome to our guide on how to restart a LAMP server on AWS. Whether you’re a seasoned developer or a newbie to the world of web hosting, you’ll find this guide helpful. We’ll take you through the entire process step-by-step, so you can troubleshoot and restart your LAMP server with ease.

Before we dive into the details, let’s take a moment to discuss what a LAMP server is and what it’s used for.

What is a LAMP server?

A LAMP server is a web server that uses Linux, Apache, MySQL, and PHP to deliver web applications to users. LAMP is an acronym for these four components. Linux is the operating system, Apache is the web server software, MySQL is the database management software, and PHP is the programming language.

LAMP servers are used to host websites, web applications, and other online services. They are popular among developers because they are open source, scalable, and reliable.

Why would you need to restart your LAMP server?

There are several reasons why you might need to restart your LAMP server. The most common are:

• The server is running slow or is unresponsive.
• You need to apply updates or changes to the server.
• You want to ensure that the server is running optimally.

Restarting your LAMP server can help to resolve these issues and ensure that your web applications and services are running smoothly.

What do you need to restart your LAMP server?

To restart your LAMP server, you’ll need:

• An AWS account with a running LAMP server instance
• Access to the server via SSH
• Basic knowledge of Linux commands

With these in place, let’s get started with the steps to restart your LAMP server on AWS.

Restarting a LAMP server on AWS: Step-by-Step Guide

Step 1: Connect to your server via SSH

The first step is to connect to your server via SSH. To do this, you’ll need to have the public IP address of your server, your private key file, and a terminal program installed on your local computer.

Here are the steps:

1. Open your terminal program and enter the following command:

ssh -i [path to your private key file] [username]@[public IP address of your server]

2. Replace [path to your private key file] with the path to your private key file and [username] with the username you used to create your server instance.
3. Press Enter and wait for the connection to establish. You should see a message similar to this:

Welcome to Ubuntu 18.04.4 LTS (GNU/Linux 4.15.0-1065-aws x86_64)

ubuntu@ip-172-31-18-174:~$

4. You’re now connected to your LAMP server via SSH.

Step 2: Check if Apache is running

The next step is to check if Apache is running. Apache is the web server software that delivers your web applications and services.

To check if Apache is running, enter the following command:

sudo service apache2 status

You should see a message similar to this:

● apache2.service – The Apache HTTP Server

Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)

Drop-In: /lib/systemd/system/apache2.service.d

└─apache2-systemd.conf

Active: active (running) since Thu 2021-07-01 09:15:56 UTC; 2h 34min ago

Main PID: 17934 (apache2)

If Apache is running, you’re ready to move on to the next step. If Apache is not running, you’ll need to start it.

Step 3: Start Apache

To start Apache, enter the following command:

sudo service apache2 start

You should see a message similar to this:

* Starting Apache httpd web server apache2

Apache should start within a few seconds. You can now move on to the next step.

Step 4: Check if MySQL is running

The next step is to check if MySQL is running. MySQL is the database management software that stores and manages your web application’s data.

To check if MySQL is running, enter the following command:

sudo service mysql status

You should see a message similar to this:

● mysql.service – MySQL Community Server

Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)

Active: active (running) since Thu 2021-07-01 09:15:24 UTC; 2h 35min ago

Main PID: 17837 (mysqld)

CGroup: /system.slice/mysql.service

If MySQL is running, you’re ready to move on to the next step. If MySQL is not running, you’ll need to start it.

Step 5: Start MySQL

To start MySQL, enter the following command:

sudo service mysql start

You should see a message similar to this:

* Starting MySQL database server mysqld

MySQL should start within a few seconds. You can now move on to the next step.

Step 6: Check if PHP is working

The next step is to check if PHP is working. PHP is the programming language that powers your web applications and services.

To check if PHP is working, enter the following command:

sudo nano /var/www/html/info.php

This will create a new file called info.php in the /var/www/html directory.

Add the following code to the file:

<?php

phpinfo();

?>

Save the file and exit.

Now, open your web browser and enter the following URL:

http://[public IP address of your server]/info.php

You should see a page that displays information about your PHP configuration. If you see this page, PHP is working correctly.

If you don’t see this page, you’ll need to troubleshoot your PHP installation. Check the error logs and consult the official PHP documentation for help.

Step 7: Restart your LAMP server

Now that you’ve checked and restarted each component of your LAMP server, you’re ready to restart the server.

To restart the LAMP server, enter the following command:

sudo reboot

You’ll be prompted to confirm the reboot. Enter Y and press Enter to confirm.

Your LAMP server will now restart. It may take a few minutes for the server to come back online.
