Discover Docker, Nginx, MySQL

Useful command in shell:

Build a docker image from a Dockerfile

docker build -t

Start an instance of a docker image

docker run -it

Really important if you want to bind some ports on the container to your own computer, use -p option.

docker run -it -p 80:80

See all images

docker images

Remove images

docker rmi

Delete all images

docker rmi $(docker images -a -q)

Remove a container

docker rm

See running containers

docker ps

List all docker containers (running and stopped).

docker ps -a

Delete all unused Docker images and cache and free space

docker system prune

Step 1: Make sure docker is installed and that you have the correct permissions

If you get the following error:

Got permission denied while trying to connect to the Docker daemon socket.

Use: sudo chmod 666 /var/run/docker.sock

If you have downloaded 42 vm use the following command: sudo systemctl stop ngnix A nginx docker is already running when you download 42 VM

Step 2: Specify where the docker should run

The subject specifies that the container should run with Debian Buster.
To do so we have to specifiy in the DockerFile the following command : FROM debian:buster

Step 3 : Install the necessary package

The -y flag stands for yes and will automatically accept the installation

RUN apt-get update && apt-get install -y wget \ #to be able to download phpmyadmin and wordpress nginx \ #for the server mariadb-server \ #to launch a sql database openssl \ #to generate a ssl certificate php7.3 php-mysql php-fpm php-pdo php-gd php-cli php-mbstring \ #to launch php

Step 4: Set nginx

Copy the file default that you can find at etc/nginx/sites-available, in your repository srcs

Edit it following the official documentation

Copy the new file in srcs in you docker: COPY srcs/[name of the nginx config file] /etc/nginx/sites-enabled

Create a symbolic link between /etc/nginx/sites-enabled and /etc/nginx/sites-available: RUN ln -s /etc/nginx/sites-available/nginx_config /etc/nginx/sites-enabled

Remove the old files default : RUN rm -rf /etc/nginx/sites-enabled/default and RUN rm -rf /etc/nginx/sites-enabled/default

Step 5: Set the ssl certificate

Use openssl dowloaded precedently to generate a certificate RUN openssl req -newkey rsa:4096 -x509 -sha256 -days 365 -nodes -out /etc/ssl/localhost.pem -keyout /etc/ssl/localhost.key -subj "/C=FR/ST=Paris/L=Paris/O=42 School/OU=llescure/CN=localhost"

Don't forget to update your nginx config file

# SSL configuration
ssl on;
ssl_certificate /etc/ssl/localhost.pem;
ssl_certificate_key /etc/ssl/localhost.key;

Step 6: Download and set phpmyadmin

Download a phpmyadmin version. I chose 4.9.2 RUN wget https://files.phpmyadmin.net/phpMyAdmin/4.9.2/phpMyAdmin-4.9.2-english.tar.gz RUN tar -xzvf phpMyAdmin-4.9.2-english.tar.gz RUN rm -rf phpMyAdmin-4.9.2-english.tar.gz RUN mv phpMyAdmin-4.9.2-english phpmyadmin

Edit the config file config.inc.php as done here

Don't forget to generate a blobfish secret here

Copy the edited files in /var/www/phpmyadmin: COPY srcs/config.inc.php /var/www/phpmyadmin

Give the rights of the directory : RUN chown -R www-data: /var/www/phpmyadmin

Step 7: Download and set wordpress

Download the latest version of wordpress RUN wget https://wordpress.org/latest.tar.gz RUN tar -xzvf latest.tar.gz RUN rm -rf latest.tar.gz

Edit the config file wp-config.php as done here

Don't forget to generate the unique keys [here](https://api.wordpress.org/secret-key/1.1/salt/ WordPress.org secret-key service)

Copy the edited files in /var/www/wordpress: COPY srcs/wp-config.php /var/www/wordpress

Give the rights of the directory : RUN chown -R www-data: /var/www/wordpress

Step 8: Run the services and create a mysql database

Create a file.sh in srcs where you will ask the docker to run nginx service, php service and mysql service service nginx start service php7.3-fpm start service mysql start

Use this [tuto] to understand mysql

Don't forget to add this line at the beggining of your file: #!/bin/bash and this one at the end of your file.sh : /bin/bash

It will tell the program to interpet the following code with bash.

Step 9: Set a file.sh which can disable autoindex while the docker is running

We will edit the nginx config file by setting autoindex to off. Remember we set it to on previously.

if grep "autoindex on" /etc/nginx/sites-enabled/nginx_config; then echo "turning off autoindex" sed -i 's/autoindex on/autoindex off/' /etc/nginx/sites-enabled/nginx_config fi nginx -s reload

Please note you can use either sites-enabled or sites-available since they are linked by a symbolic link.

If you turn off the autoindex when you type http://localhost you should see a 403 error
