    一、Docker 安装

    1. 使用国内 yum

    # yum install -y yum-utils device-mapper-persistent-data lvm2
    # yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
    

    2. 卸载旧版本的 docker

    ## 如果主机上已经有docker存在且不是想要安装的版本,需要先进行卸载。
    # yum remove -y docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-selinux \
                  docker-engine-selinux \
                  docker-engine \
                  container*
    

    3. 安装 Docker20.10 版本

    # yum -y install docker-ce-20.10.12-3.el7 docker-ce-cli-20.10.12-3.el7 vim
    

    4. 设置镜像加速

    # mkdir /etc/docker
    # vi /etc/docker/daemon.json
    
    {
      "registry-mirrors": ["https://xxxxxxxxx.mirror.aliyuncs.com"]
    }
    

    5. 启动 docker

    # systemctl start docker
    # systemctl enable docker
    # systemctl status docker
    

    二、Docker-compose 安装

    1. Docker-compose 安装

    ## github.com 可能访问超时,可以使用下面的获取下载下来后上传服务器即可
    # curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    
    # curl -k "https://dl.cactifans.com/zabbix_docker/docker-compose" -o /usr/bin/docker-compose
    
    # chmod a+x /usr/bin/docker-compose
    

    2. 查看 docker-compose 版本

    # docker-compose version
    

    三、elasticjob-cloud-scheduler 安装

    elasticjob-cloud-scheduler 启动依赖 mesos 底层库,而 mesos使用 Docker部署,而需要使用含有 mesos 底层库的镜像,制作 elasticjob 镜像

    1. 详细的 Dockerfile 文件信息

    FROM mesosphere/mesos:1.7.1
    MAINTAINER evescn
    
    RUN apt-get update && \
      apt-get -y install openjdk-8-jdk && \
      java -version
    
    ADD apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin.tar.gz /
    COPY mysql-connector-java-8.0.29.jar  /apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/lib/
    
    ENTRYPOINT ["sh", "/apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/bin/start.sh"]
    

    2. 构建镜像

    # mkidr /root/elasticjob-cloud-scheduler -pv
    # cd /root/elasticjob-cloud-scheduler
    
    ## 下载 elasticjob 文件
    # wget https://archive.apache.org/dist/shardingsphere/elasticjob-3.0.1/apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin.tar.gz
    
    ## 下载 mysql-connector-java-8.0.29.jar 文件
    # wget https://repo1.maven.org/maven2/mysql/mysql-connector-java/8.0.29/mysql-connector-java-8.0.29.jar
    
    ## 准备 dockerfile 文件
    # cat << EOF >> Dockerfile
    
    FROM mesosphere/mesos:1.7.1
    MAINTAINER evescn
    
    RUN apt-get update && \
      apt-get -y install openjdk-8-jdk && \
      java -version
    
    ADD apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin.tar.gz /
    COPY mysql-connector-java-8.0.29.jar  /apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/lib/
    
    ENTRYPOINT ["sh", "/apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/bin/start.sh"]
    
    EOF
    
    ## 构建镜像
    # docker build -t elasticjob:v3.0.1_20220428 .
    

    3. 分发镜像到节点

    # docker save elasticjob:v3.0.1_20220411 > elasticjob_v3.0.1_20220411.tar
    
    ## 连接到3台主机分别执行下面的操作
    # scp elasticjob_v3.0.1_20220411.tar 10.0.0.1:/root
    # ssh 10.0.0.1
    # docker load < elasticjob_v3.0.1_20220411.tar
    
    

    4. 创建 Event trace 日志记录数据库

    mysql 数据库部署在 10.0.0.4 主机,如何部署 mysql 服务,请自行百度

    ## 连接数据库,执行以下 SQL 语句
    
    create database elastic_job_cloud_log default character set utf8mb4 collate utf8mb4_unicode_ci;
    
    CREATE TABLE `job_execution_log` (
      `id` varchar(40) NOT NULL,
      `job_name` varchar(100) NOT NULL,
      `task_id` varchar(255) NOT NULL,
      `hostname` varchar(255) NOT NULL,
      `ip` varchar(50) NOT NULL,
      `sharding_item` int(11) NOT NULL,
      `execution_source` varchar(20) NOT NULL,
      `failure_cause` varchar(4000) DEFAULT NULL,
      `is_success` int(11) NOT NULL,
      `start_time` timestamp NULL DEFAULT NULL,
      `complete_time` timestamp NULL DEFAULT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    
    
    CREATE TABLE `job_status_trace_log` (
      `id` varchar(40) NOT NULL,
      `job_name` varchar(100) NOT NULL,
      `original_task_id` varchar(255) NOT NULL,
      `task_id` varchar(255) NOT NULL,
      `slave_id` varchar(50) NOT NULL,
      `source` varchar(50) NOT NULL,
      `execution_type` varchar(20) NOT NULL,
      `sharding_item` varchar(100) NOT NULL,
      `state` varchar(20) NOT NULL,
      `message` varchar(4000) DEFAULT NULL,
      `creation_time` timestamp NULL DEFAULT NULL,
      PRIMARY KEY (`id`),
      KEY `TASK_ID_STATE_INDEX` (`task_id`,`state`)
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
    
    

    5. 启动服务

    3节点 均需要执行以下步骤

    a | 生成 docker-compose.yml 文件

    # mkidr /data/elasticjob-cloud-scheduler/{bin,conf} -pv
    # cd /data/elasticjob-cloud-scheduler
    
    # cat << EOF >> docker-compose.yml
    version: '3'
    services:
      elasticjob-cloud-scheduler:
        image: elasticjob:v3.0.1_20220411
        restart: always
        network_mode: "host"
        hostname: elasticjob-cloud-scheduler-1
        container_name: elasticjob-cloud-scheduler-1
        volumes: # 挂载数据
          - /data/elasticjob-cloud-scheduler/bin/start.sh:/apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/bin/start.sh
          - /data/elasticjob-cloud-scheduler/conf/elasticjob-cloud-scheduler.properties:/apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/conf/elasticjob-cloud-scheduler.properties
        extra_hosts:  # 设置容器 hosts
          - "zk1:10.0.0.1"
          - "zk2:10.0.0.3"
          - "zk3:10.0.0.2"
    EOF
    

    b | 解压服务包,获取配置文件

    解压 步骤3中 tar.gz 包,负责软件 bin/ 和 conf 下配置文件到 /data/elasticjob-cloud-scheduler/{bin,conf}

    # cd /root/elasticjob-cloud-scheduler
    
    # tar -xvf apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin.tar.gz
    # cp apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/bin/start.sh /data/elasticjob-cloud-scheduler/bin
    # cp apache-shardingsphere-elasticjob-3.0.1-cloud-scheduler-bin/conf/elasticjob-cloud-scheduler.properties /data/elasticjob-cloud-scheduler/conf/
    

    c | 修改启动脚本

    # cat bin/start.sh
    
    ## 容器运行 source 报错,修改为 .
    ......
    #source ${CONF_DIR}/elasticjob-cloud-scheduler.properties
    . ${CONF_DIR}/elasticjob-cloud-scheduler.properties
    ......
    

    d | 修改配置文件

    # cat conf/elasticjob-cloud-scheduler.properties
    
    # Routable IP address
    hostname=10.0.0.1           ## 其他服务器,修改为对应IP即可
    
    # Username for mesos framework
    user=
    
    # Mesos zookeeper address
    mesos_url=zk://javaDev:edocyunjavaDev@zk1:2181,zk2:2181,zk3:2181/mesos
    
    # Role for mesos framework
    
    #mesos_role=
    
    # ElasticJob-Cloud's zookeeper address
    zk_servers=zk1:2181,zk2:2181,zk3:2181
    
    # ElasticJob-Cloud's zookeeper namespace
    zk_namespace=elasticjob-cloud
    
    # ElasticJob-Cloud's zookeeper digest
    zk_digest=user:123456
    
    # Job rest API port
    http_port=8899
    
    # Max size of job accumulated
    job_state_queue_size=10000
    
    # Event trace rdb config
    
    event_trace_rdb_driver=com.mysql.jdbc.Driver
    event_trace_rdb_url=jdbc:mysql://10.0.0.4:3306/elastic_job_cloud_log
    event_trace_rdb_username=root
    event_trace_rdb_password=root
    
    # Task reconciliation interval
    
    #reconcile_interval_minutes=-1
    
    # Enable/Disable mesos partition aware feature
    
    # enable_partition_aware=false
    
    # Auth username
    auth_username=root
    
    # Auth password
    auth_password=pwd
    EOF
    

    e | 启动服务

    # docker-compose up -d
    

    6. 查看服务

    登陆 Mesos web 界面中,查看 frameworks 页面

    访问任意节点url地址:http://10.0.0.1:5050/ ,会自动跳转到 Leader节点,再访问 http://master:5050/#/frameworks
