1、环境准备

jdk安装
/usr/local/jdk1.8.0_361/bin/java
mysql安装
create database dolphinscheduler default charset utf8;

zookeeper安装

启动zookeeper:

./bin/zkServer.sh  start

mysql-connector-java-5.1.49.jar 需要放到每个组件的Lib目录下

2、准备 DolphinScheduler 启动环境

2.1、配置用户免密及权限

useradd dolphinscheduler

#/etc/sudoers 文件修改
%dolphinscheduler ALL=(ALL) NOPASSWD: ALL

chown -R dolphinscheduler:dolphinscheduler apache-dolphinscheduler-3.1.2-bin.tar.gz

#配置3台机器免密登录针对用户dolphinscheduler

#3台机器都要执行以下命令

ssh-keygen -t rsa
cd .ssh
ssh-copy-id -i id_rsa.pub dolphinscheduler@tidb1
ssh-copy-id -i id_rsa.pub dolphinscheduler@tidb2
ssh-copy-id -i id_rsa.pub dolphinscheduler@tidb3
