2025最新版flink2.0.0安装教程(保姆级)
Flink支持多种安装模式。
local(本地)——本地模式
standalone——独立模式,Flink自带集群,开发测试环境使用
standaloneHA—独立集群高可用模式,Flink自带集群,开发测试环境使用
yarn——计算资源统一由Hadoop YARN管理,生产环境测试
flink1.13 (2021)和 flink2.0.0 (2025)之间的区别:

升级 jdk
不升级 jdk,会报如下错误:
将 jdk1.8 升级到 jdk11
上传:
解压:
[root@node01 ~]# cd /opt/modules/
[root@node01 modules]# tar -zxvf jdk-11.0.25_linux-x64_bin.tar.gz -C /opt/installs
重命名:
mv jdk-11.0.25 jdk11
如果以前有安装的 jdk8,先将其重命名:
cd /opt/installs
mv jdk jdk8
做超链接,指向新的 jdk
ln -s jdk11 jdk
同步 jdk11 到 node02,node03 上
xsync.sh /opt/installs/jdk11
将 node02 和 node03 上的 jdk 重命名为 jdk8
mv jdk jdk8
然后在 node01 上同步超链接:
xsync.sh /opt/installs/jdk
在三台电脑上,验证 java 的版本
java -version
上传Flink安装包,解压,配置环境变量
cd /opt/modules
tar -zxf flink-2.0.0-bin-scala_2.12.tgz -C /opt/installs/
cd /opt/installs
mv flink-2.0.0 flink
配置环境变量:
vim /etc/profile.d/custom_env.sh
export FLINK_HOME=/opt/installs/flink
export PATH=$PATH:$FLINK_HOME/bin
export HADOOP_CONF_DIR=/opt/installs/hadoop/etc/hadoop记得source /etc/profile
修改配置文件
① /opt/installs/flink/conf/config.yaml 【以前叫 flink-config.yaml】
yaml 格式检测器:YAML、YML在线编辑(校验、格式化)器工具(无广告) - WGCLOUD
编辑的话,可以使用 idea,由于 yaml 格式非常严格,所以使用 alt+部分选中,进行修改不容易报错
新的配置文件:
参考:OpenEuler部署Flink 1.19.2完全分布式集群_flink1.19部署-CSDN博客
第一步:要把该文件21-24行兼容jdk17的配置删掉或注释掉
第二步:修改其他配置项

# # Override the directories for temporary files. If not specified, the

# # For framework setups on Yarn, Flink will automatically pick up the

# # Add a delimited list for multiple directories, using the system directory
# # delimiter (colon ':' on unix) or a comma, e.g.:
# # /data1/tmp:/data2/tmp:/data3/tmp
# #
# # Note: Each directory entry is read from and written to by a different I/O
# # thread. You can include the same directory multiple times in order to create
# # multiple I/O threads against that directory. This is for example relevant for
# # high-throughput RAIDs.
# dirs: /tmp# classloader:
# resolve:
# # The classloading resolve order. Possible values are 'child-first' (Flink's default)
# # and 'parent-first' (Java's default).
# #
# # Child first classloading allows users to use different dependency/library
# # versions in their application than those in the classpath. Switching back
# # to 'parent-first' may help with debugging dependency issues.
# order: child-first# The amount of memory going to the network stack. These numbers usually need
# no tuning. Adjusting them may be necessary in case of an "Insufficient number

上传jar包
将资料下的flink-shaded-hadoop-2-uber-2.7.5-10.0.jar放到flink的lib目录下
分发
xsync.sh /opt/installs/flink
xsync.sh /etc/profile.d/custom_env.sh
去 node02 和 node03 上修改一个主机名:
修改 node02 和 node03 上的 taskmanager 中的 host 为 node02 和 node03
启动
#启动HDFS
start-dfs.sh
#启动集群
start-cluster.sh
#启动历史服务器
historyserver.sh start
假如 historyserver 无法启动,也就没有办法访问 8082 服务,原因大概是你没有上传 关于 hadoop 的 jar 包到 lib 下:
观察webUI
http://node01:8081 -- Flink集群管理界面 当前有效,重启后里面跑的内容就消失了
能够访问8081是因为你的集群启动着呢
http://node01:8082 -- Flink历史服务器管理界面,及时服务重启,运行过的服务都还在
能够访问8082是因为你的历史服务启动着
