一、简介DolphinScheduler是2019年中国易观公司开源的一个调度系统。目前是apache顶级项目之一https://dolphinscheduler.apache.org/zh-cnApache DolphinScheduler是一个分布式、易扩展的可视化DAG工作流任务调度平台。致力于解决数据处理流程中错综复杂的依赖关系使调度系统在数据处理流程中开箱即用拎包入住。二、安装下载安装包上传服务器并解压参考github官方文档dolphinscheduler/docs/docs/zh/guide/howto/datasource-setting.md at 3.2.0-release · apache/dolphinscheduler · GitHub解压安装tar -zxvf apache-dolphinscheduler-3.1.8-bin.tar.gz -C /opt/installs/将mysql的驱动包拷贝到所有的服务的jars目录下cd /opt/installs/apache-dolphinscheduler-3.1.8-bincp /opt/installs/hive/lib/mysql-connector-j-8.0.33.jar /opt/installs/apache-dolphinscheduler-3.1.8-bin/standalone-server/libs/standalone-servercp /opt/installs/hive/lib/mysql-connector-j-8.0.33.jar /opt/installs/apache-dolphinscheduler-3.1.8-bin/tools/libs初始化数据库在mysql数据库创建dolphinscheduler库CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci; #创建用户[非必须的] #假如你想创建会遇到密码太简单的问题 #如果提示密码等级过低 #mysql8 set global validate_password.policyLOW; set global validate_password.length4; set global validate_password.mixed_case_count0; set global validate_password.number_count0; set global validate_password.special_char_count0; #创建新用户 CREATE USER dolphinscheduler% IDENTIFIED BY 123456; GRANT ALL PRIVILEGES ON dolphinscheduler.* TO dolphinscheduler%; FLUSH PRIVILEGES;在Linux黑窗口运行export DATABASEmysql export SPRING_PROFILES_ACTIVEdolphinscheduler export SPRING_DATASOURCE_URLjdbc:mysql://bigdata001:3306/dolphinscheduler?useUnicodetruecharacterEncodingUTF-8useSSLfalseallowPublicKeyRetrievaltrue export SPRING_DATASOURCE_USERNAMEdolphinscheduler export SPRING_DATASOURCE_PASSWORD123456初始化数据库bash /opt/installs/apache-dolphinscheduler-3.1.8-bin/tools/bin/upgrade-schema.sh我们可以看到在dolphinscheduler库下面的表都有了启动修改配置文件/opt/installs/apache-dolphinscheduler-3.1.8-bin/standalone-server/conf/application.yaml修改 DolphinScheduler 的配置将其中关于数据库连接的部分修改为指向你的 MySQL 实例包括用户名、密码、数据库名等信息。以下是修改后的示例替换成下面的datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: jdbc:mysql://bigdata001:3306/dolphinscheduler?useUnicodetruecharacterEncodingUTF-8useSSLfalseallowPublicKeyRetrievaltrue username: dolphinscheduler password: 123456注意: Standalone 仅建议 20 个以下工作流使用因为其采用内存式的 H2 Database, Zookeeper Testing Server任务过多可能导致不稳定并且如果重启或者停止 standalone-server 会导致内存中数据库里的数据清空。如何启动和关闭单机版# 启动 Standalone Server 服务bash /opt/installs/apache-dolphinscheduler-3.1.8-bin/bin/dolphinscheduler-daemon.sh start standalone-server# 停止 Standalone Server 服务bash /opt/installs/apache-dolphinscheduler-3.1.8-bin/bin/dolphinscheduler-daemon.sh stop standalone-server# 查看 Standalone Server 状态bash /opt/installs/apache-dolphinscheduler-3.1.8-bin/bin/dolphinscheduler-daemon.sh status standalone-server访问管理端单机模式比较省内存单机启动不需要zk它内置了zk把我们自己的zk服务停掉。访问地址http://bigdata001:12345/dolphinscheduler/ui账号和密码 admin dolphinscheduler123至此dolphinScheduler单机版安装完毕
