dnmp PHP环境搭建 - 《Docker》

Alpine Linux 是一个面向安全，轻量级的基于musl libc与busybox项目的Linux发行版.

1、下载镜像

docker pull nginx

docker pull php:7.2.34-fpm-alpine
docker pull php:7.2.34-fpm

docker pull mysql:5.7

docker pull redis

启动MySQL
docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 —name dnmp_mysql-v F:/Git_Code/docker/lnmp/mysql/data:/var/lib/mysql -v F:/Git_Code/docker/lnmp/mysql/conf.d:/etc/mysql/conf.d mysql:5.7

启动php-fpm
docker run -d -v ~/dnmp/www:/www —name dnmp_phpfpm php:7.2.34-fpm
docker run -d -v F:/Git_Code/docker/lnmp/www:/www —name dnmp_phpfpm php:7.2.34-fpm

启动Nginx
docker run -d -p 80:80 —name dnmp_nginx -v ~/dnmp/www:/var/www/html -v ~/dnmp/nginx/conf.d:/etc/nginx/conf.d -v ~/dnmp/nginx/logs:/var/log/nginx —link dnmp_phpfpm:php —name dnmp_nginx nginx:alpine

docker run -d -p 80:80 —name dnmp_nginx -v F:/Git_Code/docker/lnmp/www:/var/www/html -v F:/Git_Code/docker/lnmp/nginx/conf.d:/etc/nginx/conf.d -v F:/Git_Code/docker/lnmp/nginx/logs:/var/log/nginx —link mphpfpm:php —name mnginx nginx

启动redis
docker run -itd —name dnmp_redis -p 6379:6379 redis

nginx 配置

server {
    listen       80;
    server_name  localhost;
    location / {
        root   /var/www/html;
        index  index.html index.htm index.php;
    }
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /var/www/html;
    }
    location ~ \.php$ {
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  /www/$fastcgi_script_name;
        include        fastcgi_params;
    }
}

配置php 模块
docker-php-ext-install mysqli

初始化源码目录

docker-php-source extract
运行上面命令后，会在/usr/src目录下生成一个php源码目录
安装完成后运行删除源码目录
docker-php-source delete

安装redis

 下载redis扩展源码
 curl -L -o redis4.3.0.tgz https://pecl.php.net/get/redis-4.3.0.tgz
 解压源码
 tar xvf redis4.3.0.tgz
 移动源码到php-ext目录下
 mv redis-4.3.0 /usr/src/php/ext/redis
 安装phpredis目录中的扩展
 docker-php-ext-install redis
 重启php-fpm容器
 docker restart 
 安装扩展
默认php镜像中提供的扩展比较少，缺少诸如mysql、gd2等常用的扩展，这样我们就需要自己安装并启用扩展。
首先进入到php容器，用php -m命令查看本地有什么扩展。
可以使用docker-php-ext-install命令来安装扩展。
$ docker-php-ext-install mysql
扩展安装好之后就可以在php.ini中启用。我们从phpinfo中可以看到，容器环境下默认的php.ini没有启用，可以从/usr/local/etc/php下将php.ini-development拷贝为php.ini。通过修改php.ini中配置，启用自己需要的扩展。下面是几个扩展安装的命令，供大家参考。
docker-php-ext-source 在容器中创建一个/usr/src/php目录
docker-php-ext-enable启用PHP扩展，省去我们手工编辑php.ini的过程
docker-php-ext-install安装并启用PHP扩展
docker-php-ext-configure经常与docker-php-ext-install搭配，在需要自定义扩展的配置时使用

安装 gd扩展

#容器中
sed -i "s@http://deb.debian.org@http://mirrors.aliyun.com@g" /etc/apt/sources.list && rm -rf /var/lib/apt/lists/* &&  cat /etc/apt/sources.list  #软件源修改为网易镜像站源
apt update  #更新软件源
apt install -y libwebp-dev libjpeg-dev libpng-dev libfreetype6-dev #安装各种库
docker-php-source extract #解压源码
cd /usr/src/php/ext/gd  #gd源码文件夹
docker-php-ext-configure gd --with-jpeg-dir=/usr/include --with-png-dir=/usr/include --with-freetype-dir=/usr/include/freetype2   #准备编译
docker-php-ext-install gd   #编译安装
php -m | grep gd
