1.kainstall 上的 readme 中 qq 不能跳转，能否给一个 qq 群号？ 2.添加 elasticsearch 之后 es 报错，需要在 es-cluster 的 yaml 中的 env 下添加

• name: discovery.zen.minimum_master_nodes value: "2"

错误信息如下： java.lang.IllegalStateException: failed to obtain node locks, tried [[/usr/share/elasticsearch/data]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing node.max_local_storage_nodes? at org.elasticsearch.env.NodeEnvironment.(NodeEnvironment.java:292) at org.elasticsearch.node.Node.(Node.java:376) at org.elasticsearch.node.Node.(Node.java:281) at org.elasticsearch.bootstrap.Bootstrap$5.(Bootstrap.java:219) at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:219) at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:399) at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:159) at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:150) at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:75) at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:116) at org.elasticsearch.cli.Command.main(Command.java:79) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:115) at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:81) For complete error details, refer to the log at /usr/share/elasticsearch/logs/k8s-logs.log
