This article brings you a tutorial (detailed steps) on deploying LNMP working environment under Docker. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

Ordinary PC environment can also use the following configuration, just replace MYSQL with the official version of mysql.

Docker installation

$ curl -sSL get.docker.com | sudo sh

Copy after login

Working directory

/lnmp/conf stores virtual host configuration
/lnmp/data /mysql Stores mysql database data
/lnmp/log Stores nginx and mysql logs
/lnmp/workspace Stores various project files

/lnmp/.env Environment variable configuration when starting docker
/lnmp/docker-compose.yml Build configuration file
/lnmp/php/Dockerfile Compile PHP configuration file

Build Nginx

Create project

First create a static file index.html
/lnmp/workspace/default/index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
</head>
<body>
    Hello, Docker!
</body>
</html>

Copy after login

Add environment variables during build

Edit .env file

SOURCE_DIR=./workspace
HTTP_HOST=80

NGINX_VERSION=alpine
NGINX_CONFD_DIR=./conf/conf.d
NGINX_CONF_FILE=./conf/nginx.conf
NGINX_LOG_DIR=./log

SOURCE_DIR=./workspace workspace文件夹挂载到nginx下的 /var/www/html
HTTP_HOST=80           宿主机的80端口映射到nginx下的80端口
NGINX_VERSION=alpine   nginx镜像使用alpine版本
NGINX_CONFD_DIR=./conf/conf.d   conf.d文件夹挂载到nginx下的/etc/nginx/conf.d
NGINX_CONF_FILE=./conf/nginx.conf   nginx.conf挂载nginx的 /etc/nginx/nginx.conf
NGINX_LOG_DIR=./log

Copy after login

Nginx.conf

Create /lnmp/conf/nginx.conf file

user  nginx;
worker_processes  1;

pid        /var/run/nginx.pid;
error_log  /var/log/nginx/nginx.error.log warn;

events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/nginx.access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}

Copy after login

Configure virtual host

Create /lnmp/conf/conf.d/default.conf file
Note: The path under root must start with /var/www/html, default is our local A folder under the workspace

server {
    listen       80;
    server_name  localhost default-server;
    root   /var/www/html/default;
    index  index.php index.html index.htm;

    access_log  /var/log/nginx/nginx.localhost.access.log  main;
    error_log  /var/log/nginx/nginx.localhost.error.log  warn;

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

Copy after login

Build Nginx configuration

Edit docker-composer.yml
The following ${} are all configured in the above .env file The variable

version: "3"
services:
  nginx:
    image: nginx:${NGINX_VERSION}
    ports:
      - ${HTTP_HOST}:80
    volumes:
      - ${SOURCE_DIR}:/var/www/html/:rw
      - ${NGINX_CONFD_DIR}:/etc/nginx/conf.d/:rw
      - ${NGINX_CONF_FILE}:/etc/nginx/nginx.conf:ro
      - ${NGINX_LOG_DIR}:/var/log/nginx/:rw
    restart: always

Copy after login

Start Nginx

After running the command, access the IP of the Raspberry Pi. Normally, Hello, Docker!

$ docker-compose up

Copy after login

# will be displayed. ##Build PHP

Edit /lnmp/.env to add PHP build variables

PHP_CONFIG_FILE=./conf/php.ini
PHP_FPM_CONFIG_FILE=./conf/php-fpm.conf

Because the php.ini configuration is a bit long, you can copy it at the following address

php.ini
php-fpm.conf

Add Dockerfile

/lnmp/php/Dockerfile

ARG PHP_VERSION
FROM php:${PHP_VERSION}-fpm
RUN apt update
RUN apt-get install -y \
        libfreetype6-dev \

      - ${PHP_PHP_CONFIG_FILE}:/usr/local/etc/php/php.ini:ro
      - ${PHP_FPM_CONFIG_FILE}:/usr/local/etc/php-fpm.d/www.conf:rw
    cap_add:
      - SYS_PTRACE
    restart: always
    networks:
      - default

Copy after login

Virtual host supports PHP parsing

/lnmp/conf/conf.d/default. conf

The php of fastcgi_pass php:9000 below refers to a service name in docker-compose.yml above, which can be used to specify the PHP version for a certain project

#...其它代码

      context: ./php
      args:
        PHP_VERSION: 7.2
        PHP_SWOOLE: ${PHP_SWOOLE_VERSION}

Copy after login

/lnmp/php/Dockerfile Download and compile swoole

# ...其它代码
ARG PHP_SWOOLE=false
RUN if [ ${PHP_SWOOLE} != false ]; then \
    curl -O http://pecl.php.net/get/swoole-${PHP_SWOOLE}.tgz -L \
    && pecl install swoole-${PHP_SWOOLE}.tgz \
    && docker-php-ext-enable swoole \
;fi
