# Apache Doris
|
|
|
|
## 简介
|
|
|
|
## 安装
|
|
|
|
### Docker Compose 方式
|
|
|
|
> [Quick Start - Apache Doris](https://doris.apache.org/docs/dev/gettingStarted/quick-start)
|
|
|
|
新建用于Docker Compose 集群编排启动目录`mkdir -p /OLAP/doris`
|
|
|
|
```bash
|
|
mkdir -p /OLAP/doris
|
|
```
|
|
|
|
编写启动脚本`start-doris.sh`
|
|
|
|

|
|
|
|
```sh

|
|
|
|
赋予权限
|
|
|
|
```bash
|
|
chmod 755 start-doris.sh
|
|
```
|
|
|
|
启动集群
|
|
|
|
```bash
|
|
./start-doris.sh
|
|
```
|
|
|
|
可以指定启动的版本通过`-v`参数，比如：
|
|
|
|
```bash
|
|
./start-doris.sh -v 2.1.8
|
|
```
|
|
|
|
使用MySQL客户端连接到集群并检查集群状态
|
|
|
|
```bash
|
|
## Check the FE status to ensure that both the Join and Alive columns are true.
|
|
mysql -uroot -P9030 -h127.0.0.1 -e 'SELECT `host`, `join`, `alive` FROM frontends()'
|
|
+-----------+------+-------+
|
|
| host | join | alive |
|
|
+-----------+------+-------+
|
|
| 127.0.0.1 | true | true |
|
|
+-----------+------+-------+
|
|
|
|
## Check the BE status to ensure that the Alive column is true.
|
|
mysql -uroot -P9030 -h127.0.0.1 -e 'SELECT `host`, `alive` FROM backends()'
|
|
+-----------+-------+
|
|
| host | alive |
|
|
+-----------+-------+
|
|
| 127.0.0.1 | 1 |
|
|
+-----------+-------+
|
|
|
|
```
|
|
|
|
|
|
|
|
### 配置
|
|
|
|
#### Linux系统环境配置（所有节点均需配置）
|
|
|
|
##### 调大文件操作配置
|
|
|
|
```bash
|
|
vim /etc/security/limits.conf
|
|
```
|
|
|
|
在文件最后添加下面几行信息(注意 * 也要复制进去)
|
|
|
|
```conf
|
|
* soft nofile 65536
|
|
* hard nofile 65536
|
|
* soft nproc 65536
|
|
* hard nproc 65536
|
|
```
|
|
|
|
可使用以下命令直接追加到配置文件内
|
|
|
|
```bash
|
|
echo "* soft nofile 65536" >> /etc/security/limits.conf
|
|
echo "* hard nofile 65536" >> /etc/security/limits.conf
|
|
echo "* soft nproc 65536" >> /etc/security/limits.conf
|
|
echo "* hard nproc 65536" >> /etc/security/limits.conf
|
|
```
|
|
|
|
保存完成需`reboot`，也可临时生效，免重启
|
|
|
|
```bash
|
|
ulimit -n 65536
|
|
```

## MySQL离线同步至Apache Doris
|
|
|
|
### 单表同步
|
|
|
|
新建配置文件`mysql_2_doris_t_base_material.json`
