Apollo注册中心docker-compose版本

1、安装docker-ce

# step 1: 安装必要的一些系统工具
sudo yum install -y yum-utils device-mapper-persistent-data lvm2
# Step 2: 添加软件源信息
sudo yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# Step 3
sudo sed -i 's+download.docker.com+mirrors.aliyun.com/docker-ce+' /etc/yum.repos.d/docker-ce.repo
# Step 4: 更新并安装Docker-CE
sudo yum makecache fast
sudo yum -y install docker-ce
# Step 4: 开启Docker服务
sudo service docker start

# 注意：
# 官方软件源默认启用了最新的软件，您可以通过编辑软件源的方式获取各个版本的软件包。例如官方并没有将测试版本的软件源置为可用，您可以通过以下方式开启。同理可以开启各种测试版本等。
# vim /etc/yum.repos.d/docker-ce.repo
#   将[docker-ce-test]下方的enabled=0修改为enabled=1
#
# 安装指定版本的Docker-CE:
# Step 1: 查找Docker-CE的版本:
# yum list docker-ce.x86_64 --showduplicates | sort -r
#   Loading mirror speeds from cached hostfile
#   Loaded plugins: branch, fastestmirror, langpacks
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            docker-ce-stable
#   docker-ce.x86_64            17.03.1.ce-1.el7.centos            @docker-ce-stable
#   docker-ce.x86_64            17.03.0.ce-1.el7.centos            docker-ce-stable
#   Available Packages
# Step2: 安装指定版本的Docker-CE: (VERSION例如上面的17.03.0.ce.1-1.el7.centos)
# sudo yum -y install docker-ce-[VERSION]

2、安装docker-compose

docker-compose下载链接

$ sudo curl -L "https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

将可执行权限应用于二进制文件：

$ sudo chmod +x /usr/local/bin/docker-compose

创建软链：

$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

$ docker-compose -v
Docker Compose version v2.2.2

3、编写docker-compose-apollo.yml

2.0以上版本的apollo有配置导出和导入功能，且在mysql 5.7和8.0导入的库和表有大小写的区分，在前期选型时就需要定位好。建议使用最新的版本，方便做配置的导入导出，否则一个个配，真的累！！！！

$ vim docker-compose-apollo.yml
version: "3"

services:
  apollo-configservice:
    container_name: apollo-configservice
    #image: apolloconfig/apollo-configservice:2.2.0
    image: apolloconfig/apollo-configservice:1.8.2
    restart: always
    ports:
      - "8080:8080"
    volumes:
      - "/opt/logs/100003171:/opt/logs/100003171"
    environment:
      - TZ='Asia/Shanghai'
      - SERVER_PORT=8080
      - EUREKA_INSTANCE_IP_ADDRESS=10.64.143.41
      - EUREKA_INSTANCE_HOME_PAGE_URL=http://10.64.143.41:8080
      - SPRING_DATASOURCE_URL=jdbc:mysql://10.64.143.41:3306/apolloconfigdb?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=apollo
      - SPRING_DATASOURCE_PASSWORD=apollo
  
  apollo-adminservice:
    container_name: apollo-adminservice
    #image: apolloconfig/apollo-adminservice:2.2.0
    image: apolloconfig/apollo-adminservice:1.8.2
    restart: always
    ports:
      - "8090:8090"
    depends_on:
      - apollo-configservice
    volumes:
      - "/opt/logs/100003172:/opt/logs/100003172"
    environment:
      - TZ='Asia/Shanghai'
      - SERVER_PORT=8090
      - EUREKA_INSTANCE_IP_ADDRESS=10.64.143.41
      - SPRING_DATASOURCE_URL=jdbc:mysql://10.64.143.41:3306/apolloconfigdb?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=apollo
      - SPRING_DATASOURCE_PASSWORD=apollo
  apollo-portal:
    container_name: apollo-portal
    #image: apolloconfig/apollo-portal:2.2.0 这里可以根据需求替换不同版本的apollo
    image: apolloconfig/apollo-portal:1.8.2
    restart: always
    ports:
      - "8070:8070"
    depends_on:
      - apollo-adminservice
    volumes:
      - "/opt/logs/100003173:/opt/logs/100003173"
    environment:
      - TZ='Asia/Shanghai'
      - SERVER_PORT=8070
      - EUREKA_INSTANCE_IP_ADDRESS=10.64.143.41
      - APOLLO_PORTAL_ENVS=pro  #配置env
      - PRO_META=http://10.64.143.41:8080  #指定PRO的eureka地址
      - SPRING_DATASOURCE_URL=jdbc:mysql://10.64.143.41:3306/apolloportaldb?useSSL=false&characterEncoding=utf8
      - SPRING_DATASOURCE_USERNAME=apollo
      - SPRING_DATASOURCE_PASSWORD=apollo

4、安装mysql

$ wget https://repo.mysql.com//mysql80-community-release-el7-3.noarch.rpm
$ rpm -ivh mysql80-community-release-el7-3.noarch.rpm
$ yum -y install mysql-community-server
$ systemctl start mysqld.service
$ grep pass /var/log/mysql/mysqld.log #启动后，会有一个root的初始密码，写入在mysqld.log中
$ mysql -uroot -p
> alter user 'root'@'localhost' identified by 'apollo';
> create user apollo@'%' identified by 'apollo';

5、导入apollo SQL 文件

$ mysql -uroot -p < apolloconfigdb.sql
$ mysql -uroot -p < apolloportaldb.sql
$ mysql -uroot -p
> grant all privileges on ApolloConfigDB.* to 'apollo'@'%' identified by
'apollo';
> grant all privileges on ApolloPortalDB.* to 'apollo'@'%';
> flush privileges;
> exit;

6、启动apollo

$ docker-compose -f docker-compose-apollo.yml up -d
$ docker-compose ps
NAME                   IMAGE                                     COMMAND                  SERVICE                CREATED             STATUS              PORTS
apollo-adminservice    apolloconfig/apollo-adminservice:1.8.2    "/apollo-adminservic…"   apollo-adminservice    18 hours ago        Up 18 hours         0.0.0.0:8090->8090/tcp, :::8090->8090/tcp
apollo-configservice   apolloconfig/apollo-configservice:1.8.2   "/apollo-configservi…"   apollo-configservice   18 hours ago        Up 18 hours         0.0.0.0:8080->8080/tcp, :::8080->8080/tcp
apollo-portal          apolloconfig/apollo-portal:1.8.2          "/apollo-portal/scri…"   apollo-portal          18 hours ago        Up 18 hours         0.0.0.0:8070->8070/tcp, :::8070->8070/tcp

7、问题发现

在调试过程中，会发现apollo-adminservice注册不到eureka，会提示http://localhost:8080/eureka/访问拒绝，这样是需要去调试依赖，apollo的服务启动是有顺序的：apollo-configservice-->apollo-adminervice-->apollo-portal，这里需要心细去发现问题。如果访问异常，可以通过docker logs -f <container_name>进行查看日志。
