**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
mkdir -p /usr/local/elasticsearch-9.0.2/data
mkdir -p /usr/local/elasticsearch-9.0.2/logs
```

设置允许所有IP进行访问，在添加下面参数让$elasticsearch-head$插件可以访问$es$

![](https://dsideal.obs.cn-north-1.myhuaweicloud.com/HuangHai/BlogImages/{year}/{month}/{md5}.{extName}/20250623130217136.png)

```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
```

### 二、安装$ik$中文分词插件

```bash
# 安装分词插件
./bin/elasticsearch-plugin install https://get.infini.cloud/elasticsearch/analysis-ik/9.0.2

# 检查插件列表
[elauser@maxkb elasticsearch-9.0.2]$ ./bin/elasticsearch-plugin list
analysis-ik
```
