Docker compose 简介

Compose 是用于定义和运行多容器 Docker 应用程序的工具。通过 Compose，您可以使用 YML 文件来配置应用程序需要的所有服务。然后，使用一个命令，就可以从 YML 文件配置中创建并启动所有服务。

使用docker compose 搭建一个 lnmp

准备工作:

代码语言：javascript复制
1. 	选择一个系统,本文章使用系统为`win10 商店里的 Ubuntu`, 也可以使用虚拟机等其他方案
2. 	安装`docker`

创建配置文件夹

创建一个配置文件夹,存放docker lnmp的配置文件,本文放在当前用户下

代码语言：javascript复制
cd ~
#创建配置文件夹
mkdir config
#创建 html 文件夹
mkdir html

创建 nginx 配置文件

代码语言：javascript复制
cd ~/config
vim nginx.conf
# 添加内容
# Default server configuration
#
worker_processes 1;
events {
  worker_connections 1024;
}
http {
  include mime.types;
  default_type application/octet-stream;
  sendfile on;
  keepalive_timeout 65;
  
  server {
        listen 80 default_server;
        listen [::]:80 default_server;

        # SSL configuration
        #
        # listen 443 ssl default_server;
        # listen [::]:443 ssl default_server;
        #
        # Note: You should disable gzip for SSL traffic.
        # See: https://bugs.debian.org/773332
        #
        # Read up on ssl_ciphers to ensure a secure configuration.
        # See: https://bugs.debian.org/765782
        #
        # Self signed certs generated by the ssl-cert package
        # Don't use them in a production server!
        #
        # include snippets/snakeoil.conf;

        root /usr/share/nginx/html;

        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html index.php;

        server_name localhost;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

        # pass PHP scripts to FastCGI server
        #
        location ~ .php$ {
               # With php-fpm (or other unix sockets):
               fastcgi_pass   php:9000;
               fastcgi_index  index.php;
               fastcgi_param  SCRIPT_FILENAME  /var/www/html/$fastcgi_script_name;
               include        fastcgi_params;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /.ht {
        #       deny all;
        #}
	}
}

创建 docker-compose 配置文件

代码语言：javascript复制
cd ~
vim docker-compose.yml
# 输入一下内容
version: "3"
services:
  nginx:
    image: nginx:alpine
    ports:
     - 80:80
    volumes:
     - ~/html:/usr/share/nginx/html
     - ~/conf/nginx.conf:/etc/nginx/nginx.conf
  php:
    image: devilbox/php-fpm:5.2-work-0.89
    volumes:
     - ~/html:/var/www/html
  mysql:
    image: mysql:5.6
    environment:
     - MYSQL_ROOT_PASSWORD=123456

创建测试 html页面

在 html 文件夹中创建各类文件,用来测试,主要有 index.html,info.php,sql_conn.php

代码语言：javascript复制
cd ~/html
#创建 index.html 用来测试 nginx
echo "hello word" > index.html
#创建 info.php 用来测试 php -e 代表转义换行符
echo -e "<?php nr echo phpinfo();n?>" > info.php

创建 sql_conn.php ,测试php 连接mysql

代码语言：javascript复制
vim sql_conn.php
# 输入一下测试代码
<?php 
    $host = "mysql";
	$user = "root";
	$password = "123456";

$conn = mysqli_connect($host,$user,$password);
if (!$conn) {
    die("Connection failed: ".mysqli_connect_error());
}
echo "Connection success!"
?>

启动 docker

代码语言：javascript复制
cd ~
# 启动docker
docker-compose up -d
# 停止docker
docker-compose down
容器 容器镜像服务 html lnmp linux
