XWiki开发指南0-使用docker安装XWiki

参考docker-xwiki项目的README，Using docker-compose一节使用docker-compose安装docker，这种方法异常简单几乎是一键安装。
我们需要三个文件如下

xwiki.cnf #xwiki的配置文件
init.sql #数据库初始化文件
docker-compose.yml #docker-compose文件

README里边的文件下载地址有点问题，文件下载不了，但是我发现其实需要的文件都在docker-xwiki项目里边，所以只要克隆docker-xwiki项目到本地就可以了。
然后把xwiki工作目录/docker-xwiki-master/11/mysql-tomcat/mysql下的两个文件拷贝到你的工作目录下，再把xwiki工作目录/docker-xwiki-master/docker-compose-mysql.yml拷贝到你的工作目录并且重命名为docker-compose.yml。然后进入你的工作目录执行

docker-compose up -d#-d参数会让容器在后台运行

执行完成如果没有发生错误会为你启动两个容器，一个是XWiki容器，一个是MySQL容器。
使用docker ps查看

CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS              PORTS                    NAMES
36a445777132        xwiki:lts-mysql-tomcat   "docker-entrypoint.s…"   31 minutes ago      Up 28 minutes       0.0.0.0:8080->8080/tcp   xwiki-mysql-tomcat-web
50c68c806a34        mysql:5.7                "docker-entrypoint.s…"   31 minutes ago      Up 28 minutes       3306/tcp, 33060/tcp      xwiki-mysql-db

这时可以访问XWiki了，打开localhost:8080
如果看到如下信息则代表XWiki安装成功了。

更换XWiki镜像

docker-compose.yml里边的XWiki镜像是lts-mysql-tomcat不是很新，我们可以使用stable-mysql-tomcat来替换。替换之后的内容如下：

version: '2'
networks:
  bridge:
    driver: bridge
services:
  web:
    # Use an already built XWiki image from DockerHub.
    image: "xwiki:stable-mysql-tomcat"#使用更新的镜像
    container_name: xwiki-mysql-tomcat-web
    depends_on:
      - db
    ports:
      - "8080:8080"
    # The DB_USER/DB_PASSWORD/DB_HOST variables are used in the hibernate.cfg.xml file.
    environment:
      - DB_USER=xwiki
      - DB_PASSWORD=xwiki
      - DB_DATABASE=xwiki
      - DB_HOST=xwiki-mysql-db
    # Provide a name instead of an auto-generated id for the xwiki permanent directory configured in the Dockerfile,
    # to make it simpler to identify in 'docker volume ls'.
    volumes:
      - xwiki-data:/usr/local/xwiki
    networks:
      - bridge
  # The container that runs MySQL
  db:
    image: "mysql:5.7"
    container_name: xwiki-mysql-db
    # - We provide a xwiki.cnf file in order to configure the mysql db to support UTF8 and be case-insensitive
    # We have to do it here since we use an existing image and that's how this image allows customizations.
    # See https://hub.docker.com/_/mysql/ for more details.
    # - Provide a name instead of an auto-generated id for the mysql data, to make it simpler to identify in
    # 'docker volume ls'
    volumes:
      - ./xwiki.cnf:/etc/mysql/conf.d/xwiki.cnf
      - mysql-data:/var/lib/mysql
      - ./init.sql:/docker-entrypoint-initdb.d/init.sql
    # Configure the MySQL database and create a user with provided name/password.
    # See https://hub.docker.com/_/mysql/ for more details.
    environment:
      - MYSQL_ROOT_PASSWORD=xwiki
      - MYSQL_USER=xwiki
      - MYSQL_PASSWORD=xwiki
      - MYSQL_DATABASE=xwiki
    networks:
      - bridge
volumes:
  mysql-data: {
    
    }
  xwiki-data: {
    
    }
