java安装更新jdk11后设置环境JAVA_HOME

背景，已经安装成功，但是环境还是java1.8

java -version

openjdk version "11.0.23" 2024-04-16 LTS

OpenJDK Runtime Environment (Red_Hat-11.0.23.0.9-2.el7_9) (build 11.0.23+9-LTS)

OpenJDK 64-Bit Server VM (Red_Hat-11.0.23.0.9-2.el7_9) (build 11.0.23+9-LTS, mixed mode, sharing)

运行elastic search还是不行，

./bin/elasticsearch
