(1)完成Docker-compose的安装
下载docker-compose稳定版本
sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
将可执行权限应用于二进制文件
sudo chmod +x /usr/local/bin/docker-compose
创建软链
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
测试安装
docker-compose --version
(2)Dockerfile编写
创建如下目录结构:
具体文件配置如下:
dockerfile_nginx
FROM nginx
MAINTAINER lin
EXPOSE 1998
dockerfile_mysql
FROM mysql
MAINTAINER lin
#设置root密码
ENV MYSQL_ROOT_PASSWORD 123456
#设置不可免密登录
ENV MYSQL_ALLOW_EMPTY_PASSWORD no
dockerfile_php
FROM php:7.4-fpm
MAINTAINER lin
FROM php:7.4-fpm
RUN apt-get update && apt-get install -y
libfreetype6-dev
libjpeg62-turbo-dev
libpng-dev
&& docker-php-ext-install pdo_mysql
&& docker-php-ext-configure gd --with-freetype --with-jpeg
&& docker-php-ext-install -j$(nproc) gd
index.html
hello man!
index.php
<?php phpinfo();?>
default.conf
server {
listen 1998; #修改映射端口
server_name localhost;
location / {
root /web/html; #修改工作目录
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location ~ .php$ {
root /web/php; #修改工作目录
fastcgi_pass myphp:9000; #修改为容器名
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
docker-compose.yml
version: "3"
services:
nginx:
image: mynginx_image #指定镜像名
container_name: mynginx #指定容器名
build:
context: .
dockerfile: dockerfile_nginx #指定dockerfile文件
ports:
- "80:1998" #修改端口映射
volumes:
- ./web:/web/html #挂载容器卷,本地/容器内修改文件后,另一方都会同步更新;
- ./default.conf:/etc/nginx/conf.d/default.conf #配置文件
php:
image: myphp_image
container_name: myphp
build:
context: .
dockerfile: dockerfile_php
environment:
MYSQL_PASSWORD: 123456
volumes:
- ./web:/web/php #挂载工作目录到本机web目录
mysql:
image: mysql_image
container_name: mysql
build:
context: .
dockerfile: dockerfile_mysql
ports:
- "3306:3306"
volumes:
- ./mysql:/var/lib/mysql
(3)使用Compose实现多容器运行机制
运行docker-compose
sudo docker-compose up -d --build
查看容器和镜像
访问
(4)服务测试
以下均修改dc/web/indeks.php
1.连接测试
<?php
$servername = "mysql";
$username = "root";
$password = "123456";
try {
$conn = new PDO("mysql:host=$servername", $username, $password);
echo "连接成功";
}
catch(PDOException $e)
{
echo $e->getMessage();
}
2.创建一个名为lin_test数据库
<?php
$servername = "mysql";
$username = "root";
$password = "123456";
try {
$conn = new PDO("mysql:host=$servername", $username, $password);
// 设置 PDO 错误模式为异常
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "CREATE DATABASE lin_test";
// 使用 exec() ,因为没有结果返回
$conn->exec($sql);
echo "数据库创建成功<br>";
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
浏览器访问
终端访问
sudo docker exec -it mysql /bin/bash
mysql -u root -p
show databases;
3.创建一个名为user的数据表
<?php
$servername = "mysql";
$username = "root";
$password = "123456";
$dbname="lin_test";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// 设置 PDO 错误模式,用于抛出异常
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// 使用 sql 创建数据表
$sql = "CREATE TABLE user (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP
)";
// 使用 exec() ,没有结果返回
$conn->exec($sql);
echo "数据表 user 创建成功";
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
浏览器访问
use lyh_test
show tables;
4.数据插入
<?php
$servername = "mysql";
$username = "root";
$password = "123456";
$dbname="lin_test";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// 开始事务
$conn->beginTransaction();
// SQL 语句
$conn->exec("INSERT INTO user (firstname, lastname, email)
VALUES ('Yuhao', 'Lin', 'john@example.com')");
$conn->exec("INSERT INTO user (firstname, lastname)
VALUES ('Jiayi', 'Zhao')");
$conn->exec("INSERT INTO user (firstname, lastname, email)
VALUES ('Li', 'Lin', 'john@example.com')");
$conn->exec("INSERT INTO user (firstname, lastname)
VALUES ('Jiayi', 'J')");
// 提交事务
$conn->commit();
echo "新记录插入成功";
}
catch(PDOException $e)
{
// 如果执行失败回滚
$conn->rollback();
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
浏览器访问
select * from user;
5.删除数据
<?php
$servername = "mysql";
$username = "root";
$password = "123456";
$dbname="lin_test";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// 开始事务
$conn->beginTransaction();
// SQL 语句
$conn->exec("DELETE FROM user where lastname='Lin'");
// 提交事务
$conn->commit();
echo "新记录插入成功";
}
catch(PDOException $e)
{
// 如果执行失败回滚
$conn->rollback();
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
?>
浏览器访问
select * from user;

主要问题:
就是查看目录结构时候要先安装一下
感谢:
自己查资料了解了dc这个工具作用,但是还是不会用,然后看博客里面有些人已经做完了,参考他们的步骤,还是很顺利的完成了,非常感谢先做完的同学们,提供了很大帮助
