CLI 安装步骤1、停止 Elasticsearch（如果正在运行）： 在安装插件之前，确保 Elasticsearch 没有在运行。命令：systemctl stop elasticsearch2、安装插件： 使用 elasticsearch-plugin 命令安装 IK 插件。进入到你的es的安装目录：如/usr/local/software/elasticsearch[root@localhost elasticsearch]# bin/elasticsearch-plugin install https://get.infini.cloud/elasticsearch/analysis-ik/8.17.0其中analysis-ik/8.17.0对应你自己安装es的版本warning: ignoring JAVA_HOME=/usr/local/software/jdk-21.0.5; using bundled JDK-> Installing https://get.infini.cloud/elasticsearch/analysis-ik/8.17.0-> Downloading https://get.infini.cloud/elasticsearch/analysis-ik/8.17.0@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ WARNING: plugin requires additional permissions @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@* java.net.SocketPermission * connect,resolveSee https://docs.oracle.com/javase/8/docs/technotes/guides/security/permissions.htmlfor descriptions of what these permissions allow and the associated risks.Continue with installation?
