### 集群启动脚本
|
|
> 也可以直接使用 `start-dfs.sh` ，需要先启动`zookeeper`
|
|
|
|
```bash
|
|
ssh_all_zookeeper.sh /usr/local/zookeeper/bin/zkServer.sh start
|
|
ssh_all_zookeeper.sh hdfs --daemon start journalnode
|
|
ssh_all_zookeeper.sh hdfs --daemon start namenode
|
|
ssh_all_zookeeper.sh hdfs --daemon start zkfc
|
|
ssh hadoop@s1 hdfs --daemon start datanode
|
|
ssh hadoop@s2 hdfs --daemon start datanode
|
|
ssh hadoop@s3 hdfs --daemon start datanode
|
|
```
|
|
|
|
### 集群停止脚本
|
|
> 也可以直接使用 `stop-dfs.sh`
|
|
```bash
|
|
ssh_all_zookeeper.sh hdfs --daemon stop namenode
|
|
ssh hadoop@s1 hdfs --daemon stop datanode
|
|
ssh hadoop@s2 hdfs --daemon stop datanode
|
|
ssh hadoop@s3 hdfs --daemon stop datanode
|
|
ssh_all_zookeeper.sh hdfs --daemon stop journalnode
|
|
ssh_all_zookeeper.sh hdfs --daemon stop zkfc
|
|
ssh_all_zookeeper.sh /usr/local/zookeeper/bin/zkServer.sh start
|
|
```

集群搭建注意事项
|
|
- `/data`这个目录六台机器均需要创建，且将所有者、所属组改为`hadoop`
