+#### 1. 启动Kakfa
+
+Kafka的运行依赖于zookeeper，需要预先启动，可以启动Kafka内置的zookeeper,也可以启动自己安装的。
+
+```shell
+# zookeeper启动命令
+bin/zkServer.sh start
+
+# 内置zookeeper启动命令
+bin/zookeeper-server-start.sh config/zookeeper.properties
+```
+
+启动单节点kafka用于测试：
+
+```shell
+# bin/kafka-server-start.sh config/server.properties
+```
+
+#### 2. 创建topic
+
+```shell
+# 创建用于测试主题
+bin/kafka-topics.sh --create \
+                    --bootstrap-server hadoop001:9092 \
+                     --replication-factor 1 --partitions 1 \
+                     --topic Hello-Kafka
+
+# 查看所有主题
+ bin/kafka-topics.sh --list --bootstrap-server hadoop001:9092
+```
+
+#### 3. 启动消费者
+
+ 启动一个控制台消费者用于观察写入情况，启动命令如下：
+
+```shell
+# bin/kafka-console-consumer.sh --bootstrap-server hadoop001:9092 --topic Hello-Kafka --from-beginning
+```
+
+
+
+```shell
+topic=Hello-Kafka, partition=0, offset=40 
+topic=Hello-Kafka, partition=0, offset=41 
+topic=Hello-Kafka, partition=0, offset=42 
+topic=Hello-Kafka, partition=0, offset=43 
+topic=Hello-Kafka, partition=0, offset=44 
+topic=Hello-Kafka, partition=0, offset=45 
+topic=Hello-Kafka, partition=0, offset=46 
+topic=Hello-Kafka, partition=0, offset=47 
+topic=Hello-Kafka, partition=0, offset=48 
+topic=Hello-Kafka, partition=0, offset=49 
+```
+
+
+
+
+
+```shell
+ bin/kafka-topics.sh --create \
+                    --bootstrap-server hadoop001:9092 \
+                     --replication-factor 1 --partitions 2 \
+                     --topic Kafka-Partitioner-Test
+```
+
+
+
+```shell
+score:6, partition=1, 
+score:7, partition=1, 
+score:8, partition=1, 
+score:9, partition=1, 
+score:10, partition=1, 
+score:0, partition=0, 
+score:1, partition=0, 
+score:2, partition=0, 
+score:3, partition=0, 
+score:4, partition=0, 
+score:5, partition=0, 
+分区器关闭
+```
