windows - elasticsearch位置参数不允许

Question

尝试使用以下命令启动elasticsearch(7.9版)节点时:

D:\temp\elasticsearch-7.9.2>  .\bin\elasticsearch.bat -Ecluster.name=my_cluster -Enode.name=node_2 Epath.data=data

我得到了错误:

D:\temp\elasticsearch-7.9.2>.\bin\elasticsearch.bat -Ecluster.name=my_cluster -Enode.name=node_2 E node.path.data=data

Answer 1

我错过了破折号-在path参数前面(我键入:Epath.data = data而不是-Epath.data = data)
一旦解决了这个问题，节点就会启动

D:\temp\elasticsearch-7.9.2>.\bin\elasticsearch.bat -Ecluster.name=my_cluster -Enode.name=node_2 -Epath.data=data
