Apache Storm 2.5.0 集群安装与配置

1、下载Apache Storm 2.5.0

https://mirrors.tuna.tsinghua.edu.cn/apache/storm/apache-storm-2.5.0/

2、准备3台服务器

192.168.42.139 node1

192.168.42.140 node1

192.168.42.141 node2

3、配置host

[root@node1 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.42.139 node1
192.168.42.140 node2
192.168.42.141 node3

4、每台服务器都需要安装python3，并且配置环境变量。如果不配置环境变量，会提示找不到python3.

export JAVA_HOME=/usr/local/jdk-17.0.9
export CLASSPATH=.:$JAVA_HOME/lib
export PYTHON_HOME=/usr/local/python37
export PATH=.:$JAVA_HOME/bin:$PYTHON_HOME/bin:$PATH

5、修改storm中的storm.yaml,这里需要注意格式问题.yaml的格式，必须是空格

########### These MUST be filled in for a storm configuration
 storm.zookeeper.servers:
      - "node1"
      - "node2"
      - "node3"
#
# nimbus.seeds: ["host1", "host2", "host3"]
 nimbus.seeds: ["node1","node2","node3"]
 storm.local.dir: "/usr/local/apache-storm/apache-storm-2.5.0/data"
 supervisor.slots.ports:
    - 6700
    - 6701
    - 6702
    - 6703
 ui.port: 8089
#

6、每台服务器都是这样的配置。

7、启动zookeeper集群

8、每台服务器都启动nimbus和supervisor
