echo date('Y-m-d H:i:s');

// Redis 测试
$redis = new Redis();
$redis->connect('172.18.0.10', 6379);
$redis->auth('123456');
$redis->set(mt_rand(1, 9999), date('Y-m-d H:i:s'));

// MySQL 测试
try {

$result = $dbh->query('SHOW TABLES');
foreach ($result as $row) {

    cd /data/php
    # 拉取 php-fpm
    docker pull php:7.2-fpm
    # 复制 php.ini-development 到本地
    docker run --rm php:7.2-fpm cat /usr/local/etc/php/php.ini-development > php.ini
    # 拉取 php-extension-installer
    docker pull mlocati/php-extension-installer
  2. 创建 Dockerfile

    RUN install-php-extensions zip gd xdebug redis \
    && docker-php-ext-install bcmath pcntl pdo_mysql

    # Add Composer
    RUN php -r "copy('https://install.phpcomposer.com/installer', 'composer-setup.php');" \
    && php composer-setup.php \
    && php -r "unlink('composer-setup.php');" \
    && mv composer.phar /usr/local/bin/composer
  3. 生成并上传镜像, 然后运行容器

    docker push sevming/php72:0.1
    # 运行容器
    docker run -itd --rm --name php --net lnmp --ip 172.18.0.7 -v /data/app:/data/app -v /data/php/php.ini:/usr/local/etc/php/php.ini sevming/php72:0.1

    3
    4
    FROM nginx:1.19.0
    RUN mkdir -p /data/app
    ENV TZ=Asia/Shanghai
    RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
  4. 生成镜像并运行容器

    1

    3
    4
    # 生成镜像
    docker build -t sevming/nginx .
    # 运行容器
    docker run -itd --rm --name nginx -p 80:80 -v /data/app:/data/app -v /data/nginx/nginx.conf:/etc/nginx/nginx.conf -v /data/nginx/conf.d:/etc/nginx/conf.d -v /data/nginx/cert:/etc/nginx/cert -v /data/nginx/logs:/var/log/nginx --net lnmp --ip 172.18.0.8 sevming/nginx
MySQL
  1. 拉取镜像

    sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
  3. 新建 Dockerfile

    1
    2
    FROM mysql:5.7
    RUN chown -R mysql:mysql /var/log/mysql
  4. 生成镜像并运行容器

    1
    2
    3
    4
    # 生成镜像
    docker build -t sevming/mysql .
    # 运行容器
    docker run --rm -itd --name mysql -p 3306:3306 -v /data/mysql/data:/var/lib/mysql -v /data/mysql/my.cnf:/etc/mysql/conf.d/my.cnf -v /data/mysql/logs:/var/log/mysql --net lnmp --ip 172.18.0.9 -e MYSQL_ROOT_PASSWORD=123456 sevming/mysql
Redis
  1. 进入 redis 目录 (cd /data/redis), 并新建 redis.conf

    1
    2
    3
    4
    # 持久化存储
    appendonly yes
    # 密码设置
    requirepass 123456
  2. 创建 Dockerfile

    1
    2
    FROM redis:latest
    CMD [ "redis-server", "/usr/local/etc/redis.conf" ]
  3. 生成镜像并运行容器

    1
    2
    3
    4
    # 生成镜像
    docker build -t sevming/redis .
    # 运行容器
    docker run --rm -d --name redis -p 6379:6379 -v /data/redis/data:/data -v /data/redis/redis.conf:/usr/local/etc/redis.conf --net lnmp --ip 172.18.0.10 sevming/redis
浏览器访问 服务器IP

以上这种方式, 需要一个个启动容器, 可以采用 docker-compose 来配置服务

修改 /data/nginx/conf.d/default.conf
