docker 搭建php 開發環境 添加擴展redis、swoole、xdebug

docker-compose搭建lnmp

先決條件

• 首先需要安裝docker

• 安裝docker-compost

1、創建lnmp工作目錄

#創建三個目錄
mkdir lnmp && cd lnmp
mkdir -p nginx/conf php mysql/data lnmp/www


#編寫nginx 配置文件  nginx/conf/default.conf
vim nginx/conf/default.conf

server {
    listen       80;
    root   /usr/share/nginx/html;
    index   index.html index.htm index.php;


    # 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;
    }

    location / {
        index  index.html index.htm index.php ;
        try_files $uri $uri/ /index.php?$query_string;
        autoindex  on;
    }


    location ~ \.php$ {
        #php73是容器命名
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        include        fastcgi_params;
        fastcgi_param  PATH_INFO $fastcgi_path_info;
        fastcgi_param  SCRIPT_FILENAME  /var/www/html/$fastcgi_script_name;
    }

}

2、編寫php鏡像文件Dockerfile

因為php需要安裝一些擴展文件 使用dockerfile進行鏡像構建

vim php/Dockerfile

# 基礎
FROM php:7.2-fpm

# 修改時區
ENV TZ Asia/Shanghai
RUN date -R

# 換源
RUN echo 'deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free' >/etc/apt/sources.list
RUN echo 'deb http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free' >>/etc/apt/sources.list
RUN apt-get update --fix-missing && apt-get install -y libpng-dev libjpeg-dev libfreetype6-dev  \
        && docker-php-ext-configure gd --with-freetype-dir=/usr/include --with-jpeg-dir=/usr/include/jpeg \
        && docker-php-ext-install gd mysqli opcache pdo_mysql gd zip

ENV PHPREDIS_VERSION 5.0.1
ENV PHPXDEBUG_VERSION 2.6.0
ENV PHPSWOOLE_VERSION 4.5.10

RUN pecl install redis-$PHPREDIS_VERSION \
    && pecl install xdebug-$PHPXDEBUG_VERSION \
    && pecl install swoole-$PHPSWOOLE_VERSION \
    && docker-php-ext-enable redis xdebug swoole

RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" \
     && php composer-setup.php \
     && php -r "unlink('composer-setup.php');" \
     && mv composer.phar /usr/local/bin/composer \
     && composer config -g repo.packagist composer https://packagist.phpcomposer.com
RUN apt-get install -y git

RUN rm -rf /var/cache/apt/* \
    && rm -rf /var/lib/apt/lists/*
RUN mkdir /var/lib/sessions \
    && chmod o=rwx -R /var/lib/sessions
#容器啟動時執行指令
CMD ["php-fpm"]

3、創建compose 的yml文件

version: "3.9"
services:
  #配置nginx
  nginx:
    #鏡像名稱 nginx:latest
    image: nginx
     #自定義容器的名稱
     #container_name: c_nginx
    ports:
      - "80:80"

    #lnmp目錄和容器的/usr/share/nginx/html目錄進行綁定，設置rw權限
    #將宿主機的~/lnmp/nginx/conf/default.conf和容器的/etc/nginx/conf.d/default.conf進行綁定
    volumes:
      - ./data/:/usr/share/nginx/html:rw
      - ./nginx/conf/default.conf:/etc/nginx/conf.d/default.conf
    #設置環境變量，當前的時區
    environment:
      TZ: "Asia/Shanghai"
    #容器是否隨docker服務啟動重啟
    restart: always
    #容器加入名為lnmp的網絡
    networks:
      - lnmp

  #配置php
  php:
    #image: php:7.4-fpm   //由於php擴展比較多  直接build自己的Dockerfile 不需要官方鏡像
    build: ./php
    container_name: php
    volumes:
      - ./data/:/var/www/html/:rw
    restart: always
    cap_add:
      - SYS_PTRACE
    networks:
      - lnmp

  #配置mysql
  mysql:
    image: mysql:latest   
    ports:
      - "3306:3306"
    volumes:
      - ./mysql/data/:/var/lib/mysql/:rw
    restart: always
    networks:
      - lnmp
    #設置密碼
    environment:
      MYSQL_ROOT_PASSWORD: "123456"
      TZ: :"Asia/Shanghai"
networks:
  lnmp:

4、執行compose命令

#構建鏡像環境
docker-compose up   # -d 為后台執行

5、擴展命令

docker-compose ps  查看compose服務
docker-compose run web env #查看web服務的環境變量
docker-compose stop 停止服務
docker-compose down  #關閉並刪除改服務容器   #傳遞--volumnes同時刪除使用的數據卷

6、php7.4 dockerfile

FROM php:7.4-fpm


# 設置時區
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

# 換源(國內源)
#RUN echo 'deb http://mirrors.ustc.edu.cn/debian stable main contrib non-free' >/etc/apt/sources.list
#RUN echo 'deb http://mirrors.ustc.edu.cn/debian stable-updates main contrib non-free' >>/etc/apt/sources.list

# 更新安裝依賴包和PHP核心拓展
RUN apt-get update && apt-get install -y \
       libfreetype6-dev  libjpeg-dev libjpeg62-turbo-dev  libpng-dev \
   && docker-php-ext-configure gd --with-freetype --with-jpeg \
   && docker-php-ext-install -j$(nproc) gd mysqli opcache pdo_mysql 

#7.4添加zip擴展有問題 
#RUN apk add libzip-dev && docker-php-ext-install zip


ENV PHPREDIS_VERSION 5.0.1
ENV PHPXDEBUG_VERSION 3.1.3
ENV PHPSWOOLE_VERSION 4.8.7

RUN pecl install redis-$PHPREDIS_VERSION \
   && pecl install xdebug-$PHPXDEBUG_VERSION \
   && pecl install swoole-$PHPSWOOLE_VERSION \
   && docker-php-ext-enable redis xdebug swoole



# 安裝 Composer
ENV COMPOSER_HOME /root/composer
RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
ENV PATH $COMPOSER_HOME/vendor/bin:$PATH

CMD ["php-fpm"]

WORKDIR /var/www/html

當前構造的鏡像地址。可直接使用 無需再次構造

docker pull fangsinan/php:7.4
