+# 为DataSophon制作dolphinscheduler-3.1.8安装包
+
+### DataSophon修改datasophopn-manager中conf/meat/DDP-1.2.0/DS/service_ddl.json，修改以下参数
+```
+"version": "3.1.8",
+"packageName": "dolphinscheduler-3.1.8.tar.gz",
+"decompressPackageName": "dolphinscheduler-3.1.8",
+```
+
+### 下载apache-dolphinscheduler-3.1.8-bin.tar.gz包，在服务器中解压缩
+```shell
+tar -xvf ./apache-dolphinscheduler-3.1.8-bin.tar.gz
+```
+### 修改文件名称，主要是要与上面decompressPackageName一致
+```shell
+mv apache-dolphinscheduler-3.1.8-bin dolphinscheduler-3.1.8
+```
+### 增加jmx文件夹
+```shell
+cp jmx dolphinscheduler-3.1.8
+```
+### 修改以下脚本的启动命令使jmx生效
+./dolphinscheduler-3.1.8/alert-server/bin/start.sh
+
+./dolphinscheduler-3.1.8/api-server/bin/start.sh
+
+./dolphinscheduler-3.1.8/master-server/bin/start.sh
+
+./dolphinscheduler-3.1.8/worker-server/bin/start.sh
+
+```主要是JAVA_OPTS中添加了jmx内容
+JAVA_OPTS=${JAVA_OPTS:-"-server -javaagent:$BIN_DIR/../../jmx/jmx_prometheus_javaagent-0.16.1.jar=12359:$BIN_DIR/../../jmx/prometheus_config.yml  -Duser.timezone=${SPRING_JACKSON_TIME_ZONE} -Xms1g -Xmx1g -Xmn512m -XX:+PrintGCDetails -Xloggc:gc.log -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=dump.hprof"}
+```
+### jmx的端口号需要和service_ddl.json中的jmx端口号一致
+* api-server：12356
+* master-server：12357
+* worker-server：12358
+* alert-server：12359
+
+### 修改dolphinscheduler-3.1.8/bin/dolphinscheduler-daemon.sh脚本，在几乎使最下方的地方$state == "STOP"的地方增加一行exit 1
+```shell
+(status)
+    get_server_running_status
+    if [[ $state == "STOP" ]]; then
+      #  font color - red
+      state="[ \033[1;31m $state \033[0m ]"
+      #增加一行，使得DataSophon执行脚本时可以有返回值判断状态
+      exit 1
+    else
+      # font color - green
+      state="[ \033[1;32m $state \033[0m ]"
+    fi
+    echo -e "$command  $state"
+    ;;
+
+  (*)
+    echo $usage
+    exit 1
+    ;;
+```
+
+### 增加mysql依赖包，将mysql8依赖包放入到每个组件的lib中
+参考ds的说明https://github.com/apache/dolphinscheduler/blob/3.1.8-release/docs/docs/zh/guide/howto/datasource-setting.md
+
+### 打压缩包
+```shell
+tar -zcvf dolphinscheduler-3.1.8.tar.gz dolphinscheduler-3.1.8
+```
+### 生成md5文件
+```shell
+md5sum dolphinscheduler-3.1.8.tar.gz > dolphinscheduler-3.1.8.tar.gz.md5
+```
+### 将dolphinscheduler-3.1.8.tar.gz和dolphinscheduler-3.1.8.tar.gz.md5上传到DataSophon的安装包中
+```shell
+cp ./dolphinscheduler-3.1.8.tar.gz /opt/datasophon/DDP/packages/
+cp ./dolphinscheduler-3.1.8.tar.gz.md5 /opt/datasophon/DDP/packages/
+```
