怎么让DolphinDB开机自动运行

我在2台服务器上部署了一个DolphinDB集群，一台服务器上部署了一个控制节点+一个代理节点+二个数据节点，另一台部署了一个代理节点+二个数据节点。操作系统是centos 8，请问服务器重启后，怎么才能让DolphinDB集群自动启动？

1.按照官网的多服务器集群部署，配置好上述的环境，教程网址：https://gitee.com/dolphindb/Tutorials_CN/blob/master/multi_machine_cluster_deploy.md
最后能够成功启动该集群，web端控制界面如下图所示，State状态为绿色。

2.完成多服务器集群部署后，进入服务器A，终端执行：

ps aux |grep dolphindb

获得如下信息：

[xhtang@CentOS8 server]$ ps aux |grep dolphindb

xhtang 3105 0.0 0.1 12108 2452 pts/0 S+ 18:21 0:00 grep --color=auto dolphindb

根据上述信息，创建一个自动运行dolphindb的脚本，例如在home/user/shell中创建dolphindb.sh，脚本内容如下：

#!/bin/bash

#dolphindb Auto

cd /home/user/dolphindb_cluster/server/

nohup ./dolphindb -console 0 -mode controller -home data -config config/controller.cfg -clusterConfig config/cluster.cfg -logFile log/controller.log -nodesFile config/cluster.nodes &

nohup ./dolphindb -console 0 -mode agent -home data -config config/agent.cfg -logFile log/agent.log &

nohup ./dolphindb -home /home/xhtang/dolphindb_cluster/server/data/P1-datanode2 -logFile /home/xhtang/dolphindb_cluster/server/log/P1-datanode2.log -jobLogFile /home/xhtang/dolphindb_cluster/server/log/P1-datanode2_job.log -keyPath /home/xhtang/dolphindb_cluster/server/data/P1-agent/keys -subPort 24120 -console 0 -mode datanode -localSite 192.168.1.122:24117:P1-datanode2 -webLoginRequired 0 -lanCluster 1 -perfMonitoring 1 -maxMemSize 5 -sites 192.168.1.126:24117:P2-datanode2,192.168.1.126:24115:P2-datanode1,192.168.1.122:24117:P1-datanode2,192.168.1.122:24115:P1-datanode1 -dfsReplicationFactor 1 -workerNum 4 -localExecutors 3 -dataSync 0 -maxPubConnections 5 -enableHTTPS 0 -maxPartitionNumPerQuery 9999999999 -subThrottle 1 -config /noconfig -maxSubConnections 64 -chunkCacheEngineMemSize 5 -controllerSite 192.168.1.122:24111:master &

nohup ./dolphindb -home /home/xhtang/dolphindb_cluster/server/data/P1-datanode1 -logFile /home/xhtang/dolphindb_cluster/server/log/P1-datanode1.log -jobLogFile /home/xhtang/dolphindb_cluster/server/log/P1-datanode1_job.log -keyPath /home/xhtang/dolphindb_cluster/server/data/P1-agent/keys -subPort 24118 -console 0 -mode datanode -localSite 192.168.1.122:24115:P1-datanode1 -webLoginRequired 0 -lanCluster 1 -perfMonitoring 1 -maxMemSize 5 -sites 192.168.1.126:24117:P2-datanode2,192.168.1.126:24115:P2-datanode1,192.168.1.122:24117:P1-datanode2,192.168.1.122:24115:P1-datanode1 -dfsReplicationFactor 1 -workerNum 4 -localExecutors 3 -dataSync 0 -maxPubConnections 5 -enableHTTPS 0 -maxPartitionNumPerQuery 9999999999 -subThrottle 1 -config /noconfig -maxSubConnections 64 -chunkCacheEngineMemSize 5 -controllerSite 192.168.1.122:24111:master &

注意：

cd的路径是dolphindb安装的路径，需要根据自己的设置进行修改；

第6、7行（较长的两行，启动数据节点的命令行）内容从终端窗口执行ps aux |grep dolphindb返回的信息中复制粘贴，并在开头加上nohup，在结尾加上&，实现后台运行。

再将home/user/shell文件夹下创建好的dolphindb.sh复制到/etc/profile.d/下，具体可以执行：

sudo cp dolphindb.sh /etc/profile.d

3. 进进入服务器B，终端执行：

ps aux |grep dolphindb

获得如下信息：

[xhtang@CentOS8 server]$ ps aux |grep dolphindb

#!/bin/bash

cd /home/user/dolphindb_cluster/server/

注意：

cd的路径是dolphindb安装的路径，需要根据自己的设置进行修改；

第5、6行（较长的两行，启动数据节点的命令行）内容从终端窗口执行ps aux |grep dolphindb返回的信息中复制粘贴，并在开头加上nohup，在结尾加上&，实现后台运行。

再将home/user/shell文件夹下创建好的dolphindb.sh复制到/etc/profile.d/下，具体可以执行：

sudo cp dolphindb.sh /etc/profile.d

4.重启电脑即可完成自动启动dolphindb

5.可以打开web控制界面，看到：
