Tutorial on deploying LNMP working environment under Docker (detailed steps)

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

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

       
  Hello, Docker!  

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

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; }

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; } }

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

Start Nginx

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

$ docker-compose up

# 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 \ libjpeg62-turbo-dev \ libmcrypt-dev \ libpng-dev \ unixodbc-dev \ gcc g++ make autoconf libc-dev pkg-config

Add build PHP

Edit /lnmp/docker-compose.yml file

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 php: build: context: ./php args: PHP_VERSION: 7.2 volumes: - ${SOURCE_DIR}:/var/www/html/:rw - ${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

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

Add files

/lnmp/workspace/default/index.php

      
Start preview
If you have not terminated the process before, you can terminate it with ctrl c Run the following command.
      
If nothing unexpected happens, the IP when accessing the Raspberry Pi will display Hello, PHP!.

      
$ docker-compose up
      
Add PHP extension
/lnmp/.env Add variables, The following is a swoole extension demonstration. For other extensions, please refer to the following operations.
      

      
PHP_SWOOLE_VERSION=4.2.10
/lnmp/docker-compose.yml Add variables
      

      
php: build: context: ./php args: PHP_VERSION: 7.2 PHP_SWOOLE: ${PHP_SWOOLE_VERSION}
/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
Recompile
      
Note: If the Dockerfile is changed, you must add --build and recompile it once, otherwise it will not take effect when docker-compose up
      

      
$ docker-compose up --build
Preview
      
Edit /lnmp/workspace/default/index.php to save, access the IP of the Raspberry Pi, and as expected you can find the swoole extension
      

      

      
Build MYSQL
MYSQL persistence
      
The Docker container service has been deleted to ensure that data will not be lost
      
Create the /lnmp/data/mysql folder
Build-time variables
      
Edit the /lnmp/.env file and add the mysql service port, login password and data persistence folder.
      

      
MYSQL_HOST_PORT=3306 MYSQL_PASSWORD=1234 MYSQL_DATA_DIR=./data/mysql
Build configuration
      
version: "3" services: #... 其它代码 mysql: image: tobi312/rpi-mysql ports: - ${MYSQL_HOST_PORT}:3306 volumes: - ${MYSQL_DATA_DIR}:/var/lib/mysql:rw environment: MYSQL_ROOT_PASSWORD: "${MYSQL_PASSWORD}"
Startup
      
After starting, use the data connection tool to test, link address: Raspberry Pi IP Port: 3306 Username: root Password: 1234
      

      
$ docker-compose up
So far, your own LNMP working environment is ready.
