docker 配置 php 运行环境

创建自定义 php 镜像

1. 新建目录

sudo mkdir -p /www/docker
sudo cd /www/docker
sudo vi Dockerfile

2. dockerfile 的内容

FROM php:7.2-fpm-alpine
MAINTAINER fengyexjtu@126.com

    --with-jpeg-dir=/usr/include/ \
&& docker-php-ext-install -j"$(getconf _NPROCESSORS_ONLN)" gd \
&& pecl install -o -f redis \
&& rm -rf /tmp/pear \
&& docker-php-ext-enable redis \
&& rm -r /var/cache/apk/*
EXPOSE 9000

3. 构建

docker build -t php:7.2-fpm-alpine-dcwd .

使用 docker-compose 启动服务

1. 编辑 docker-compose.yml

docker-compose.yml

version: "3.1"
services:
  nginx:
    image: nginx
    container_name: nginx
    restart: always
    ports:
      - "8480:80"
      - "8443:443"
    volumes:
      - /www/data/nginx/conf.d:/etc/nginx/conf.d
      - /www/default:/www/default
    networks:
      csl:
        ipv4_address: 173.20.0.2

  php:
    image: php:7.2-fpm-alpine-dcwd
    container_name: php7.2
    restart: always
    volumes:
      - /www/default:/www/default
    networks:
      csl:
        ipv4_address: 173.20.0.3
  mysql5:
    image: mysql:5.7
    container_name: mysql5
    restart: always
    ports:
      - "8406:3306"
    environment:
      MYSQL_ROOT_PASSWORD: root
    volumes:
      - /www/data/mysql/mysql5:/var/lib/mysql
      #- /www/data/mysql/mysql5/conf/my.cnf:/etc/my.cnf
      #- /www/data/mysql/mysql5/init:/docker-entrypoint-initdb.d
    networks:
      csl:
        ipv4_address: 173.20.0.4
  mysql8:
    image: mysql:8.0
    container_name: mysql8
    restart: always
    ports:
      - "8407:3306"
    environment:
      MYSQL_ROOT_PASSWORD: root
    volumes:
      - /www/data/mysql/mysql8:/var/lib/mysql
    networks:
      csl:
        ipv4_address: 173.20.0.5
networks:
  csl:
    driver: bridge
    ipam:
      config:
        - subnet: 173.20.0.0/16

2. 创建 nginx 的配置文件

server {
    listen       80;
    server_name  localhost;
    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;
    location / {
        root   /www/default;
        index  index.php index.html index.htm;
    }
    #error_page  404              /404.html;
    # 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;
    }
    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}
    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           /www/default;
        fastcgi_pass   php7.2:9000;#php容器名或者php容器ip
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$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;
    #}
}

1. 创建 测试页面

sudo mkdir -p /www/default/
sudo vi /www/default/index.php

<?php
$con = mysqli_connect("173.20.0.4", "root", "root", "shop");
if ($con) {
    echo '连接 MYSQL 成功';
} else {
    echo "连接 MySQL 失败: " . mysqli_connect_error();
} mysqli_close($con);

4. 配置 mysql 远程连接

docker exec -it mysql5 bash
mysql -u root -p
use mysql;
update user set host='%' where user='root';
flush privileges;

5. 启动测试

问题总结

1. docker-compose.yml 中的 ip 设置 要选择没有被占用的 ip 段

2. 关于目录规划

/www
├── data
│   ├── mysql
│   │   ├── mysql5
│   │   └── mysql8
│   └── nginx
│       └── conf.d
│           └── default.conf
├── default
│   └── index.php
└── docker
    ├── docker-compose.yml
    └── Dockerfile

nginx 的文件一定要放到 /www/data/nginx/conf.d/中,如果服务已经启动而没有或者修改了配置文件(*.conf),一定要进入到 nginx container 中,手动使用命令nginx -s reload重新加载配置文件

3. Mysql8 目前是多余的,可以去除.
