laravel - Laravel docker :adsist-docker_app_1以代码1退出

Question

我试图建立一个Laravel项目。

设置是:

Centos

Apache

MySql

我为App，Web，数据库拆分了容器

和应用程序容器无法运行:(

这是我的 docker-compose.yml:

version: '2'
services:

  # The Application
  app:
    build:
      context: ./
      dockerfile: app.dockerfile
    working_dir: /var/www
    volumes:
      - ./:/var/www
    environment:
      - "DB_PORT=3306"
      - "DB_HOST=database"

  # The Web Server
  web:
    build:
      context: ./
      dockerfile: web.dockerfile
    working_dir: /var/www
    volumes_from:
      - app
    ports:
      - 8080:80

  # The Database
  database:
    image: mysql:5.6
    volumes:
      - dbdata:/var/lib/mysql
    environment:
      - "MYSQL_DATABASE=homestead"
      - "MYSQL_USER=homestead"
      - "MYSQL_PASSWORD=secret"
      - "MYSQL_ROOT_PASSWORD=secret"
    ports:
      - "33061:3306"

volumes:
  dbdata:

这是我的app.dockerfile

FROM centos:7.5.1804

RUN yum update -y

RUN yum install epel-release http://rpms.remirepo.net/enterprise/remi-release-7.rpm yum-utils -y && \
    yum-config-manager --enable remi-php72 && \
    yum update -y

RUN yum install vim wget curl unzip \
    php php-json php-gd php-mbstring php-pdo php-xml php-mysqlnd -y

RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" && \
    php composer-setup.php --install-dir=/usr/local/bin --filename=composer && \
    rm -rf composer-setup.php

RUN curl -sL https://rpm.nodesource.com/setup_8.x | bash - && \
    yum install nodejs -y

RUN yum clean all

EXPOSE 80

# Keep container active
CMD ["/usr/sbin/httpd", "-D", "FOREGROUND"]

这是我的web.dockerfile:

FROM httpd:2.4

COPY httpd.conf /etc/httpd/conf/httpd.conf

当我运行 docker-compose up时，显示一些消息:

app_1 | AH00526: Syntax error on line 119 of /etc/httpd/conf/httpd.conf: app_1 | DocumentRoot '/var/www/html' is not a directory, or is not readable

adsist-docker_app_1 exited with code 1

Answer 1

设置为apache documentroot的/var/www/html在大多数linux发行版中都很流行，但是httpd docker镜像中不是这样。另外，即使您将http.conf修改为使用/var/www/html，您仍然应该挂载到/var/www/html，而不是/var/www。

回到httpd图片，您可以看到下一个:

$ docker run -idt httpd:2.4
docker ps
CONTAINER ID    IMAGE       COMMAND              CREATED STATUS  PORTS               NAMES
182c63e24082    httpd:2.4   "httpd-foreground"   3 seconds ago   Up 1 second 80/tcp  clever_bassi
$ docker exec -it clever_bassi /bin/bash
root@182c63e24082:/usr/local/apache2/conf# cat httpd.conf
......
DocumentRoot "/usr/local/apache2/htdocs"
......

因此，如果不更改默认设置，则应将主机的文件挂载到 /usr/local/apache2/htdocs上以提供服务。

而且，您的 COPY httpd.conf /etc/httpd/conf/httpd.conf中的 Dockerfile也不正确，应该是 COPY httpd.conf /usr/local/apache2/conf/httpd.conf。
