1、拉取镜像
php和mysql不要用最新的版本，听说有很多坑
docker pull nginx
docker pull php:7.1-fpm
docker pull mysql:5.7
2. 创建文件夹
# 网站目录
mkdir -p /data/www
# nginx 配置
mkdir -p /data/nginx/conf.d
# mysql数据
mkdir -p /data/mysql/data
# mysql配置
mkdir -p /data/mysql/conf.d
3、创建 Nginx 容器
将nginx配置文件nginx.conf复制到主机/data/nginx目录中
docker run --rm nginx cat /etc/nginx/nginx.conf > /data/nginx/nginx.conf
创建nginx
docker run --name nginx \
-v /data/www:/usr/local/html \
-v /data/nginx/conf.d:/etc/nginx/conf.d \
-v /data/nginx/nginx.conf:/etc/nginx/nginx.conf:ro \
--net=host \
-d nginx
4. 创建 PHP 容器
docker run --name php-fpm \
-v /data/www:/var/www/html \
-d php:7.1-fpm
5. 查看 PHP 容器的IP
docker inspect php-fpm --format='{{.NetworkSettings.IPAddress}}'
# 返回 IP
172.17.0.2
6. 创建 Nginx 配置文件
vim /data/nginx/conf.d/default.conf
server {
listen 80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.php index.html index.htm;
}
location ~ \.php(.*)$ {
root /var/www/html; # php 容器的目录,进 php 容器查看
fastcgi_pass 172.17.0.2:9000; # php 容器的IP
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
修改后重启一下 nginx 容器
docker restart nginx
7. 测试
编写测试页
echo "<?php phpinfo(); ?>" > /data/www/info.php
测试
curl http://127.0.0.1/info.php
8. 创建 MySQL 容器
docker run --name mysql \
-p 3306:3306 \
-v /data/mysql/conf.d:/etc/mysql/conf.d \
-v /data/mysql/data:/var/lib/mysql \
-e MYSQL_ROOT_PASSWORD=123456 -d mysql:5.7
9. PHP 安装 MySQLI 扩展
# 进入容器
docker exec -it php-fpm /bin/bash
# 安装 pdo_mysql mysqli
docker-php-ext-install pdo_mysql mysqli
# CTRL + D 退出容器
docker restart php-fpm
10. 连接 MySQL测试
查看mysql的ip
docker inspect mysql --format='{{.NetworkSettings.IPAddress}}'
# 返回 IP
172.17.0.3
编辑连接测试文件 vim /data/www/conn.php
<?php
$serve = '172.17.0.3:3306';
$username = 'root';
$password = '123456';
$dbname = 'mysql';
$mysqli = new Mysqli($serve,$username,$password,$dbname);
if ($mysqli->connect_error) {
die('connect error:'.$mysqli->connect_errno);
}
$mysqli->set_charset('UTF-8');
$result = $mysqli->query('select * from user');
$data = $result->fetch_all();
print_r($data);
?>
测试
curl http://127.0.0.1/conn.php
