+### 一、下载$JDK17$
+
+```shell
+# 下载wget
+yum install wget -y
+
+# 进入工作目录
+cd /usr/local
+
+# 下载文件
+wget https://download.oracle.com/java/17/archive/jdk-17.0.10_linux-x64_bin.tar.gz
+
+# 解压+移动
+tar -xzvf jdk-17.0.10_linux-x64_bin.tar.gz && mv jdk-17.0.10 /usr/local/jdk17 && rm -rf jdk-17.0.10_linux-x64_bin.tar.gz

+# 配置
+echo 'export JAVA_HOME=/usr/local/jdk17' | sudo tee -a /etc/profile && \
+echo 'export PATH=$JAVA_HOME/bin:$PATH' | sudo tee -a /etc/profile
+source /etc/profile
+
+# 检查
+java -version 2>&1 | grep "17.0.10"
+```
+
+
+
+### 二、系统检查
+
+**关闭 $swap$ 分区**
+
+```shell
+# 临时关闭
+swapoff -a 
+
+# 永久关闭
+sed -i '/swap/s/^/#/' /etc/fstab
+```
+
+**关闭防火墙**
+
+```shell
+systemctl stop firewalld
+systemctl disable firewalld
+systemctl status firewalld
+```
+
+
+
+**配置 $chrony$ 服务**
+
+```shell
+# 安装与启动
+dnf install -y chrony
+systemctl enable --now chronyd
+
+vi /etc/chrony.conf
+# 添加内容
+server ntp.aliyun.com iburst
+server time.cloudflare.com iburst
+
+# chrony验证
+timedatectl status
+chronyc tracking | grep "Leap status"
+```
+
+**设置系统最大打开文件句柄数**
+
+```shell
+# 临时生效
+ulimit -n 65535  
+
+# 永久生效
+vi /etc/security/limits.conf 
+
+# 增加以下内容
+*         soft     nofile      1048576
+*         hard     nofile      1048576

+root      soft     nofile      1048576
+root      hard     nofile      1048576
+```
+
+**修改虚拟内存区域数量为**
+
+```shell
+sysctl -w vm.max_map_count=2000000
+```
+
+**关闭透明大页**
+
+```shell
+echo never > /sys/kernel/mm/transparent_hugepage/enabled
+echo never > /sys/kernel/mm/transparent_hugepage/defrag
+```
+
+**执行生效** 
+
+```

+```
+
+## 三、部署$doris$
+
+**1、解压安装包**
+
+```shell
+cd /usr/local
+# 下载
+wget https://apache-doris-releases.oss-accelerate.aliyuncs.com/apache-doris-3.0.5-bin-x64.tar.gz
+# 解压
+tar -xzvf apache-doris-3.0.5-bin-x64.tar.gz 
+# 迁移目录
+mv apache-doris-3.0.5-bin-x64 doris && rm -rf apache-doris-3.0.5-bin-x64.tar.gz 
+```
+
+**2、部署$FE$**
+
+```shell
+# 创建目录
+mkdir -p /usr/local/doris/doris-meta
+mkdir -p /usr/local/doris/doris-storage
+```
+
+修改$FE$配置文件
+
+```shell
+vi /usr/local/doris/fe/conf/fe.conf
+# 增加内容
+JAVA_HOME=/usr/local/jdk17
+
+#网段按照实际情况，如服务器的IP是10.10.14.250，那么网关就是10.10.14.0
+priority_networks = 10.10.14.0/24
+
+#元数据存储目录
+meta_dir = /usr/local/doris/doris-meta
+```
+
+**3、启动$FE$**
+
+```shell
+# 加上--daemon 后台启动
+/usr/local/doris/fe/bin/start_fe.sh --daemon
+```
+
+> **备注**：
+
+```shell
+# 如果有问题，到下面的路径查看日志
+/usr/local/doris/fe/log
+```
+
+**4、验证 $FE$ 状态**
+
+```shell
+#  安装MySQL客户端核心组件
+dnf install mysql -y
+
+#  验证安装
+mysql --version                     # 查看版本信息
+
+# 通过 MySQL 客户端连接 看是否能连接成功
+mysql -h 127.0.0.1 -P 9030 -uroot
+```
+
+![](https://dsideal.obs.cn-north-1.myhuaweicloud.com/HuangHai/BlogImages/202505091305243.png)
+
+**5、部署$BE$**
+
+```shell
+# 增加配置信息
+vi /usr/local/doris/be/conf/be.conf
+
+JAVA_HOME=/usr/local/jdk17
+priority_networks = 10.10.14.0/24
+storage_root_path = /usr/local/doris/doris-storage
+```
+
+**6、启动$BE$**
+
+```shell
+# 后台启动命令
+/usr/local/doris/be/bin/start_be.sh --daemon
+```
+
+
+
+## 四、集群管理
+
+**1、将$BE$添加到$FE$**
+
+```shell
+# 使用 MySQL 客户端连接 FE
+mysql -h 127.0.0.1 -P 9030 -uroot
+ 
+# 添加 BE 节点
+ALTER SYSTEM ADD BACKEND "127.0.0.1:9050";
+
+# 修改密码
+SET PASSWORD FOR 'root' = PASSWORD('DsideaL147258369');
+```
+
+**2、验证节点状态** 
+
+```shell
+SHOW PROC '/backends'\G
+-- 检查 `Alive` 字段为 `true`
+```
+
+![](https://dsideal.obs.cn-north-1.myhuaweicloud.com/HuangHai/BlogImages/202505091312869.png)
+
+**3、创建数据库**
+
+```sql
+create database yltcharge;
+```

+
+### 六、配置$CDC$需要$JDK21$
+
+```shell
+# 进入工作目录
+cd /usr/local
+
+# 下载文件
+wget https://download.oracle.com/java/21/archive/jdk-21.0.7_linux-x64_bin.tar.gz

+# 解压+移动
+tar -xzvf jdk-21.0.7_linux-x64_bin.tar.gz && mv jdk-21.0.7 /usr/local/jdk21 && rm -rf jdk-21.0.7_linux-x64_bin.tar.gz
