云收藏项目已经开源2年多了，作为当初刚开始学习 Spring Boot 的练手项目，使用了很多当时很新的技术，现在看来其实很多新技术是没有必要使用的，但做为学习案例来讲确实是一个绝佳的 Spring Boot 实践。

从开源到现在，写了一些教程给大家介绍如何部署云收藏，如何在IDE中运行云收藏，但是仍然有很多的朋友不知道如何使用，如何部署？就像“请提供一份云收藏数据结构” 这样的问题我至少都回答了一百多次，并且在 github 关闭了近十个类似的问题。

这也从另外一个方面可以看出，部署云收藏项目对一些朋友还是比较复杂，现在有了 Docker 我们就可以愉快的解决这个问题，只需三步就可以部署云收藏项目，打造专属个人的收藏系统。

云收藏

一些朋友可能还不了解云收藏，给大家简单介绍一下：

云收藏是一个使用 Spring Boot 构建的开源网站，可以让用户在线随时随地收藏的一个网站，在网站上分类整理收藏的网站或者文章，可以作为稍后阅读的一个临时存放。作为一个开放开源的软件，可以让用户从浏览器将收藏夹内容导入到云收藏，也支持随时将云收藏收集的文章导出去做备份。

核心功能点：

收藏、分类、检索文章
导出、导出（包活从浏览器中）
可以点赞、分享、讨论
注册、登录、个人账户
临时收藏、查看别人收藏
其它…

项目使用技术：

Vue
Bootstrap
jQuery
Thymeleaf
Spring Data Jpa
Spring Boot Mail
WebJars
Mysql
Tomcat
Redis

Redis 后期去掉是由于服务器资源有限和部署麻烦

项目改造

依赖环境

准备一台系统为 Centos 7 以上的服务器，系统需要安装 Docker 和 Docker Compos 环境，安装方法可以参考前面两篇文章：

Docker 化改造

项目改造后的项目机构图如下：

因为上一篇文章Spring Boot 2.0(五)：Docker Compose + Spring Boot + Nginx + Mysql 实践已经介绍了此类项目结构和内容含义，因此这里主要描述新增内容。

docker-compose.yaml 文件

我们首先来看一下docker-compose.yaml文件：

version: '3'
services:
  nginx:
   container_name: favorites-nginx
   image: nginx:1.13
   restart: always
   ports:
   - 80:80
   - 443:443
   volumes:
     - ./nginx/conf.d:/etc/nginx/conf.d
     - /tmp/logs:/var/log/nginx
     
    
  mysql:
   build: ./mysql
   environment:
     MYSQL_DATABASE: favorites
     MYSQL_ROOT_PASSWORD: root
     MYSQL_ROOT_HOST: '%'
     TZ: Asia/Shanghai
   ports:
   - "3306:3306"
   volumes:
     - ./mysql_data:/var/lib/mysql
   restart: always
      
  app:
    restart: always
    build: ./app
    working_dir: /app
    volumes:
      - ./app:/app
      - ~/.m2:/root/.m2
      - /tmp/logs:/usr/local/logs
    expose:
      - "8080"
    command: mvn clean spring-boot:run -Drun.profiles=docker
    depends_on:
      - nginx
      - mysql

相对上一篇内容本次的docker-compose.yaml文件主要新增了两部分的内容：

1、将 Nginx 和 app 的日志映射到宿主机上，方便我们查看日志
2、将 Mysql 的数据存储映射到宿主机上，这样的好处是不至于将集群关掉之后数据丢失

docker-compose.yaml文件中，日志部分：

version: '3'
services:
  nginx:
   volumes:
     - /tmp/logs:/var/log/nginx
  app:
   volumes:
     - /tmp/logs:/usr/local/logs

分别将 Nginx 和云收藏项目日志映射到宿主机的/tmp/logs，方便我们查看项目日志。

定制 mysql 初始化信息

docker-compose.yaml文件中，Mysql 变化内容：

version: '3'
services:
  mysql:
   build: ./mysql
   environment:
     TZ: Asia/Shanghai
   volumes:
     - ./mysql_data:/var/lib/mysql

我将有变化的内容都摘了出来，mysql 新增了 TZ 环境变量将时区指向上海，另外我们将 Mysql 镜像内容提出来，放到项目的 mysql 目录下单独构建。mysql 目录下有两个文件，一个是 Dockerfile 定义 Mysql 镜像，一个是 my.cnf 文件定义 Mysql 编码等信息。

my.cnf 文件内容

#省略一部分
...
character_set_server=utf8
character_set_filesystem=utf8
collation-server=utf8_general_ci
init-connect='SET NAMES utf8'
init_connect='SET collation_connection = utf8_general_ci'
skip-character-set-client-handshake

此文件主要的作用是让 Mysql 支持 UTF-8.

Dockerfile 文件内容

FROM mysql/mysql-server:5.7
COPY my.cnf /etc/my.cnf

使用 Mysql5.7 版本，并且将同目录下的 my.cnf 拷贝到服务器/etc/my.cnf中

这样 Mysql 的相关信息就定义好了。

其它

其它内容变化不大，nginx 目录下存放着 Nginx 的配置文件，项目新增application-docker.properties文件，将数据库连接部分修改即可。

改造完成之后，我们只需要将项目拷贝到部署服务器然后执行：docker-compose up就可以启动。

部署

我已经将项目的改造内容提交到 github 上面，这样大家部署的时候仅需要三步，即可成功部署云收藏项目。

1、下载源码解压

下载最新发布版本

wget https://github.com/cloudfavorites/favorites-web/archive/favorites-1.1.1.zip

解压

unzip favorites-1.1.1.zip

进入目录

cd favorites-web-favorites-1.1.1/

2、修改配置文件

修改文件application-docker.properties

vi app/src/main/resources/application-docker.properties

修改内容如下

favorites.base.path=http://xx.xxx.xx.xx/

地址为部署服务器的地址

3、启动项目

配置完成后，后台启动

[root@~]# docker-compose up -d
Creating network "favoriteswebfavorites111_default" with the default driver
Creating favorites-nginx                  ... done
Creating favoriteswebfavorites111_mysql_1 ... done
Creating favoriteswebfavorites111_app_1   ... done

启动完成后，浏览器访问上面配置地址：http://xx.xxx.xx.xx/，就可以看到云收藏的首页了。

辅助内容

启动后想查看某个容器内的服务运行情况，可以使用以下命令进入：

使用docker ps查看宿主机上面运行的 Docker 容器

[root@VM_73_217_centos ~]# docker ps
CONTAINER ID        IMAGE                            COMMAND                  CREATED             STATUS                  PORTS                                      NAMES
a466ce6e58a5        favoriteswebfavorites111_app     "/usr/local/bin/mv..."   16 hours ago        Up 16 hours             8080/tcp                                   favoriteswebfavorites111_app_1
1b4f1b912de0        nginx:1.13                       "nginx -g 'daemon ..."   16 hours ago        Up 16 hours             0.0.0.0:80->80/tcp, 0.0.0.0:443->443/tcp   favorites-nginx
65b481bb7741        favoriteswebfavorites111_mysql   "/entrypoint.sh my..."   16 hours ago        Up 16 hours (healthy)   0.0.0.0:3306->3306/tcp, 33060/tcp          favoriteswebfavorites111_mysql_1

根据上面查询的 Docker 容器 ID 信息，执行下面命令

docker exec -ti CONTAINER_ID  bash
#比如进入项目容器中
[root@VM_73_217_centos ~]# docker exec -ti a466ce6e58a5 bash
root@a466ce6e58a5:/app# ps -ef|grep java
...

退出容器执行以下命令：

root@a466ce6e58a5:/app# exit
exit
[root@VM_73_217_centos ~]#

这样以后如果我们想部署云收藏项目就变的非常简单，仅仅需要三步可以愉快的搭建自己的收藏系统了，小伙伴们赶紧动起手来。
