+
+## Features
+
+Dolphinscheduler-rpm can build dolphinscheduler rpms
+- Easy to deploy dolphinscheduler on cluster.
+- Easy to manage dolphinscheduler by configuration management tools, such as [ambari](https://ambari.apache.org/), [puppet](https://www.puppet.com/) and [ansible](https://www.ansible.com/) and monitor dolphinscheduler services.
+
+## How to Build
+
+You should install rpm-build, make on your dev machine
+
+
+```bash
+# rockylinux-8
+yum install -y make, rpm-build
+```
+
+```bash
+# ubuntu-22.04
+sudo apt install -y make, rpm
+```
+and then
+
+```bash
+make
+```
+
+## How to Use
+
+Download the dolphinscheduler rpm files into local dictionary, and make local yum repo.
+
+Before you deploy dolphinscheduler, you should deploy zookeeper and mysql first
+
+If you want to install dolphinscheduler-master-server on a node, you should
+
+```bash
+# install jdk8
+yum install java-1.8.0-openjdk-devel -y
+# install dolphinscheduler-master-server
+yum install -y dolphinscheduler-master-server dolphinscheduler-tools mysql-connector-j
+ln -s /usr/share/java/mysql-connector-j.jar /usr/lib/dolphinscheduler/api-server/libs/
+ln -s /usr/share/java/mysql-connector-j.jar /usr/lib/dolphinscheduler/master-server/libs/
+```
+
+Edit dolphinscheduler_env.sh
+here is example:
+
+```bash
+#######################################
+. /usr/lib/bigtop-utils/bigtop-detect-javahome
+DATABASE=mysql
+REGISTRY_ZOOKEEPER_CONNECT_STRING="172.18.0.2:2181"
+
+# JAVA_HOME, will use it to start DolphinScheduler server
+export JAVA_HOME=${JAVA_HOME:-/opt/java/openjdk}
+
+# Database related configuration, set database type, username and password
+export DATABASE=${DATABASE:-postgresql}
+export SPRING_PROFILES_ACTIVE=${DATABASE}
+export SPRING_DATASOURCE_URL="jdbc:mysql://localhost:3306/dev"
+export SPRING_DATASOURCE_USERNAME="dev"
+export SPRING_DATASOURCE_PASSWORD="devpass"
+#######################################
+```
+
+start services
+
+```bash
+# init databases
+cd /usr/lib/dolphinscheduler/tools/bin && bash -x upgrade-schema.sh
+# service start
+service dolphinscheduler-api-server start
+service dolphinscheduler-master-server start
+```

+
+## Features
+
+Dolphinscheduler-rpm 可以构建rpm包
+- 方便dolphinscheduler部署在集群上
+- 方便与配置管理工具集成，如 [ambari](https://ambari.apache.org/)， [puppet](https://www.puppet.com/) ， [ansible](https://www.ansible.com/) ，并且管理dolphinscheduler后台服务
+
+## How to Build
+
+在你的开发的机器上安装make，与rpm-build
+
+
+```bash
+# rockylinux-8
+yum install -y make, rpm-build
+```
+
+```bash
+# ubuntu-22.04
+sudo apt install -y make, rpm
+```
+and then
+
+```bash
+make
+```
+
+## How to Use
+
+下载rpm包到本地目录，并构建yum repo，在你部署之前，确保安装了zookeeper与mysql.
+下面演示怎么部署dolphinscheduler-master-server
+
+```bash
+# install jdk8
+yum install java-1.8.0-openjdk-devel -y
+# install dolphinscheduler-master-server
+yum install -y dolphinscheduler-master-server dolphinscheduler-tools mysql-connector-j
+ln -s /usr/share/java/mysql-connector-j.jar /usr/lib/dolphinscheduler/api-server/libs/
+ln -s /usr/share/java/mysql-connector-j.jar /usr/lib/dolphinscheduler/master-server/libs/
+```
+
+编辑 dolphinscheduler_env.sh
+
+```bash
+#######################################
+. /usr/lib/bigtop-utils/bigtop-detect-javahome
+DATABASE=mysql
+REGISTRY_ZOOKEEPER_CONNECT_STRING="172.18.0.2:2181"
+
+# JAVA_HOME, will use it to start DolphinScheduler server
+export JAVA_HOME=${JAVA_HOME:-/opt/java/openjdk}

+export SPRING_DATASOURCE_USERNAME="dev"
+export SPRING_DATASOURCE_PASSWORD="devpass"
+#######################################
+```
+
+开启服务
+
+```bash
+# 初始化数据库
+cd /usr/lib/dolphinscheduler/tools/bin && bash -x upgrade-schema.sh
+# 启动服务
+service dolphinscheduler-api-server start
+service dolphinscheduler-master-server start
