[Part 1] Setup LEMP environment with Docker - Setup Nginx and PHP

Hi guys, In this series, we are going to setup LEMP Stack (Linux, Nginx, MySQL, PHP). Mainly it is used by web developers. I am assuming you have a basic idea about Docker & How it works.

In this blog, We are going to setup PHP and Nginx.

Why Docker?

I will not go too much deep, You can find more resources over the internet about the docker.

Docker makes the installation process very smooth and it gives your isolated environment as the container.

With the docker, There will be no more excuses like:

”It’s working on my machine.” :D

Because your docker environment remains the same across the platforms, So above excuses will going to turn with:

”It’s working on every machine” ;)

In Short, Docker makes tech person’s life easy like the developer, tester, etc.

My Machine configuration:

Docker Version: 18.09.7
Docker Compose Version: 1.24.1
RAM: 8GB
OS: Ubuntu 18.04

Make sure docker and docker-compose is installed on your machine.

Step 1: Create folders:

mkdir LEMP
cd LEMP
mkdir {public_html,nginxi_conf}

public_html: It will contains your PHP code.
nginx_conf: It will contains your Nginx configuration file.

Step 2: Create Nginx conf file

Go to nginx_conf:

cd nginx_conf

Create file lemp-docker.conf (You can give any name according to your requirement) & Paste below configuration block.

server {
		listen 80;
		server_name _;
		root /public_html;

		location / {
				index index.php index.html;
		}

		location ~* \.php$ {
				fastcgi_pass    php:9000;
				fastcgi_index   index.php;
				include         fastcgi_params;
				fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
				fastcgi_param PATH_INFO $fastcgi_path_info;
		}
}

Save and Exit from folder.

Step 3: Create file docker-compose.yml

Create file docker-compose.yml in LEMP folder & paste the below lines:

version: '3'

services:
 web:
  image: nginx
  ports:
   - "80:80" 
  volumes:
   - ./public_html:/public_html
   - ./nginx_conf:/etc/nginx/conf.d
   - /tmp/nginx_logs:/var/log/nginx 
  networks:
   - nginx-php

 php:
  image: php:7.2-fpm
  volumes:
  - ./public_html:/public_html
  ports:
  - "9000:9000"
  networks:
  - nginx-php

networks:
 nginx-php:

Here we have created the network with the name nginx-php. You can check more about the networks here.

You can set volumes path according to your requirement.

Step 4: Let’s Up the containers

Create container:

cd LEMP/
docker-compose up

Note: Make sure no other service is running on port 80.

Output:

docker compose up

You can hit the localhost on your browser.

Once you hit the localhost check nginx logs:

cat /tmp/nginx_logs/access.log 

172.25.0.1 - - [16/May/2020:12:51:04 +0000] "GET / HTTP/1.1" 404 556 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36" "-"

Now stop the containers by simply hitting Ctrl + c. Now run docker-compose in detached mode. It will run in the background.

docker-compose up -d

Lists containers

docker-compose ps

Step 5: Let’s Create test.php

Go to LEMP/public_html

cd LEMP/public_html

Create file test.php & paste below code:

<?php

echo phpinfo();

Step 6: Run test.php

Visit http://localhost/test.php.

Output:

phpinfo

At the End

We have successfully created Nginx and PHP Environment. In Part 2, We will check, How we can add MySQL to this environment.
