大数据系列之:安装pulsar详细步骤
- 一、Pulsar版本和jdk对应关系
- 二、安装JDK
- 三、设置和激活jdk环境变量
- 四、下载和解压Pulsar
- 五、查看Pulsar目录
- 六、启动Pulsar standalone cluster
- 七、创建Kafka Topic
- 八、往Topic写入数据
- 九、消费pulsar的Topic
一、Pulsar版本和jdk对应关系
点击下面的链接查看Pulsar版本和jdk对应关系:
- https://github.com/apache/pulsar/blob/master/README.md#pulsar-runtime-java-version-recommendation
二、安装JDK
点击链接下载JDK:
- https://adoptium.net/temurin/releases/?variant=openjdk17
tar -zxvf OpenJDK17U-jdk_x64_linux_hotspot_17.0.6_10.tar.gz
三、设置和激活jdk环境变量
设置环境变量
vim /etc/profile
export JAVA_HOME="/data/src/jdk17"
PATH=$PATH:$JAVA_HOME/bin
激活环境变量
source /etc/profile
四、下载和解压Pulsar
下载Pulsar
wget https://archive.apache.org/dist/pulsar/pulsar-2.11.0/apache-pulsar-2.11.0-bin.tar.gz
解压Pulsar
tar -zxvf apache-pulsar-2.11.0-bin.tar.gz
五、查看Pulsar目录
cd apache-pulsar-2.11.0
ls
bin conf data examples instances lib LICENSE logs NOTICE packages-storage README
六、启动Pulsar standalone cluster
