离线安装方式（错误过程记录）：

参考文档：https://docs.byzer.org/#/byzer-lang/zh-cn/extension/README

Byzer-lang 支持插件安装，删除，获取列表等。安装和删除插件的语法如下

!plugin <pluginType> <operation> [-] "<pluginName>";

• pluginType 表示插件类型，目前有 app ds et 三种。
• operation 表示操作类型，add remove。
• pluginName 表示插件名称。
• 安装插件时，请在插件名称前加横杠，并以空格分割。删除时，无需空格。

安装插件前，请配置 Byzer-lang 数据湖目录 streaming.datalake.path，支持本地文件系统，HDFS，对象存储。 Byzer-lang 下载插件至数据湖目录，并热加载之。获取列表语法如下：

!plugin list [pluginType];

若不指定插件类型，Byzer-lang 返回所有插件。

!plugin list  会报错，提示目录不存在。

具体解决方式

通过手工方式，将一台已经安装好openmldb插件的目录，copy到新服务器相应的目录：

插件目录是engine根下面的data 和store，这两个目录配置为delta数据库路径。

重启./bin/bizer.sh restart

在note上执行plugin list，不报错;

执行创建openml的数据表代码，报错如下：

        查看log文件，错误信息如下： 从日志看，是以为delta没有元数据。估计这样直接复制文件方式不行。

离线安装方式2（成功过程记录）：

1.下载地址：

http://store.mlsql.tech/run?action=downloadPlugin&pluginType=MLSQL_PLUGIN&pluginName=byzer-openmldb-3.0&version=0.1.0-SNAPSHOT

2.将jar包放到byzerlang下的plugin目录

3.修改byzer-lang下面conf目录的byzer.properties.override的streaming.plugin.clzznames

增加入口：tech.mlsql.plugins.openmldb.ByzerApp

byzer.server.mode=all-in-one
byzer.server.dryrun=false

byzer.server.runtime.driver-memory=24g

streaming.name=Byzer-lang-engine
streaming.rest=true
streaming.thrift=false
streaming.platform=spark
streaming.spark.service=true
streaming.job.cancel=true
streaming.datalake.path=./data/
streaming.driver.port=9003
streaming.enableHiveSupport=false
streaming.plugin.clzznames=tech.mlsql.plugins.ds.MLSQLExcelApp,tech.mlsql.plugins.assert.app.MLSQLAssert,tech.mlsql.plugins.shell.app.MLSQLShell,tech.mlsql.plugins.mllib.app.MLSQLMllib,tech.mlsql.plugins.llm.LLMApp,tech.mlsql.plugins.execsql.ExecSQLApp,tech.mlsql.plugins.openmldb.ByzerApp

spark.mlsql.log.driver.enablePrint=true
spark.mlsql.path.schemas=oss,s3a,s3,abfs,file
spark.mlsql.session.expireTime=10d
spark.local.dir=/home/byzerllm/byzerllm_stroage
 

 4.重启byzer-lang服务

cd   bin

./byzer.sh restart

5.遗留问题：

在byzer-note上执行plugin list 命令报错
