How to quickly build an LNMP environment with Docker (latest)

Preface

Tip: Here you can add the approximate content to be recorded in this article:
For example: With the continuous development of artificial intelligence, machine learning technology has become more and more important. Many people have started to learn machine learning. This article introduces the basic content of machine learning.

Tip: The following is the main content of this article. The following cases can be used for reference

1. Mysql?

1. Pull the mysql image

docker pull mysql:5.6 

2. Run to start the mysql container

docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=xy123456 --name xy_mysql mysql:5.6 

Parameter Description:
-d makes the container run in the background
-p Add port mapping from host to container
-e sets the mysql environment variable and the initial root password. –name gives the container a name. The last parameter is the image name, which is the name of the image to be pulled.

2. Install php-fpm

1. Pull the php-fpm image

docker pull php:7.0-fpm

You can also pull docker pull php:7.4.20-fpm docker pull php:7.3.28-fpm These versions are in the warehouse, feel free to pull

2. Run to start the php-fpm container

docker run -d -v D:/docker/nginx:/var/www/html -p 9000:9000 --link xy_mysql:mysql --name xy_phpfpm php:7.0-fpm

Parameter Description:
-d makes the container run in the background
-p Add port mapping from host to container
-v adds directory mapping, D:/docker/nginx on the host is mapped to /var/www/html, that is, the contents of the directory are synchronized. You can directly copy the directory where you want to write code under the host'D:/docker/nginx'. If $PWD is valid, it refers to the current directory. I used this parameter to report an error, so I copied and pasted the path directly.
–name gives the container a name –link establishes a connection with another container so that the service of another container can be used in the current container. The last parameter is the image name, which is the name of the image to be pulled.

3. Enter the php-fpm container

docker exec -it xy_phpfpm bash

Parameter Description
-t creates a pseudo terminal in the container
-i Interact with the container's standard input (STDIN)

After creating an index.php file in /var/www/html/, you will find that it also exists locally, which means it is synchronized because the corresponding directories of the host and the container have been mapped when the container is started;

4. Install the pdo_mysql module

Since we will use the pdo module for testing later, we will install the pdo_mysql module.

docker-php-ext-install pdo_mysql

php -m prints to see if the installation is successful;

After installation, the extension may not be displayed after printing in phpinfo(). There will be modified steps in the subsequent test.

3. Install nginx

1. Pull the nginx image

docker pull nginx:1.10.3

2. Run the nginx container

docker run -d -p 80:80 -v D:/docker/nginx:/var/www/html --link xy_phpfpm:phpfpm --name xy_nginx nginx:1.10.3

3. Enter the nginx container and modify the nginx configuration file to support PHP

docker exec -it xy_nginx bash 

It is recommended to change it in /etc/nginx/conf.d/default.conf;
fastcgi_pass write php:7.0-fpm:9000. The alias you write may become invalid.
root is written as the code directory set by the previous PHP container;

4. Test whether the installation is successful

Modify index.php code

<?php

phpinfo(); 

After using the previously installed command, phpinfo() does not have mysql, so you need to go into php.ini to change it.

5. Modify the configuration

docker exec -it xy_phpfpm bash 

In this container, php.ini is in /usr/local/etc/php php.ini-development php.ini-production
These two files are the php.ini files. They are exactly the same. You can tell what they mean by looking at the names. Just open the extension=php_pdo_mysql.dll extension.

6. Link to mysql test

Modify index.php code

try {
    $con = new PDO('mysql:host=xy_mysql;dbname=mysql', 'root', 'xy123456');
    $con->query('SET NAMES UTF8');
    $res = $con->query('select * from user');
    while ($row = $res->fetch(PDO::FETCH_ASSOC)) {
      // echo "id:{$row['id']} name:{$row['name']}";
	  print_r($row);
    }
} catch (PDOException $e) {
     echo 'Error reason:' . $e->getMessage();
}

If no error is reported, it is successful

Summarize

If successful, the primary environment is set up. Be careful during the entire process and check more information when configuring the file.
