+
+**2、安装$JDK$$21$**
+
+```sh
+sudo yum install java-21-openjdk-devel
+echo 'export JAVA_HOME=/usr/lib/jvm/java-21-openjdk
+export PATH=$JAVA_HOME/bin:$PATH' >> ~/.bashrc
+
+source ~/.bashrc
+```
+
+**3、上传文件到$linux$服务器**
+
+```sh
+# 如果没有 rz 命令 先安装
+yum -y install lrzsz
+ 
+# rz 打开弹窗 选择下载好的文件 确认 在哪个目录下执行，就会上传到该目录下
+rz -be
+```
+
+ **4、新建用户并设置密码**
+
+```sh
+# 创建用户
+useradd elauser
+
+# 设置密码 符合密码规范 大写 + 小写 + 数字 + 特殊字符 + 大于八位
+passwd elauser 
+
+#输入密码：
+DsideaL@123 
+
+tar -zxvf elasticsearch-9.0.2-linux-x86_64.tar.gz
+sudo chown -R elauser:elauser /usr/local/elasticsearch-9.0.2
+# 进入解压文件并编辑配置文件
+cd elasticsearch-9.0.2/config
+vi elasticsearch.yml
+# 修改数据目录和日志目录

+
+```yaml
+network.host: 0.0.0.0
+http.cors.enabled: true
+http.cors.allow-origin: "*"
+```
+
+**5、修改系统配置**
+
+```sh
+# m.max_map_count 值太低
+# 临时解决方案（需要root权限）
+sudo sysctl -w vm.max_map_count=262144
+
+# 永久解决方案（需要root权限）
+echo "vm.max_map_count=262144" | sudo tee -a /etc/sysctl.conf
+sudo sysctl -p
+
+# 验证是否有效
+sysctl vm.max_map_count
+```
+
+**6、启动**
+
+```sh
+# 启动
+su - elauser
+
+cd /usr/local/elasticsearch-9.0.2/bin
+# ./elasticsearch-keystore create
+
+# 启动 -d = damon 守护进程
+./elasticsearch -d
+
+
+# 访问地址
+https://10.10.14.206:9200
+
+# 日志文件 
+/usr/local/elasticsearch-9.0.2/logs/elasticsearch.log
+```
+
+ 弹出输入账号密码，这里需要重置下密码，再登录 进入安装目录的bin目录下
+
+执行下面命令 就会在控制台打印出新密码 账号就是  elastic 
+
+```
+./elasticsearch-reset-password -u elastic
+```
