如果没有dfs,需要配置dfs路径的位置也可以用本地file路径替换,倒也能启动集群和作业,但不要这样用,在作业容错和重启时会出现问题,比如找不到存在其他机器磁盘上的状态。
HA 配置为 3masters 3slavers
java1.8->scala2.12->zookeeper3.4.14->flink1.8.0_2.12
1.配置集群间ssh免密登陆
生成ssh密钥
ssh-keygen -t rsa
三个确认回车生成ssh密钥
将ssh密钥拷贝到其他主机
ssh-copy-id -i /root/.ssh/id_rsa.pub username@ipaddr
2.java1.8+ 集群环境需要java1.8及以上
3.scala 2.11 或 2.12,flink的安装包应该与scala环境对应
官网下载 scala-2.12.8安装包到/opt下
tar -xvf scala-2.12.8.tar
向/etc/profile添加环境变量(见最后)
4.zookeeper flink的standalone HA(高可用部署)需要zookeeper支持
官网下载 zookeeper-3.4.14安装包到/opt下
tar -xvf zookeeper-3.4.14.tar
向/etc/profile添加环境变量(见最后)
配置zookeeper集群
cd /opt/zookeeper-3.4.14/
vi /conf/zoo.cfg 配置zookeeper(见最后)
按照配置文件中的路径创建data目录,这里
mkdir /opt/zkData/data
在data目录新建myid文件,添加编号,编号与配置文件中对应
vi /opt/zkData/data/myid (见最后)
启动zookeeper集群
zkServer.sh start
5.flink
官网下载 flink-1.8.0-bin-scala_2.12安装包到/opt下
tar -xvf flink-1.8.0-bin-scala_2.12.tar
向/etc/profile添加环境变量(见最后)
配置flink集群
standalone集群高可用性部署需要配置flink-conf.yaml masters 和 slaves三个文件 (见最后)
jobmanager.rpc.address 该地址在高可用模式下会被忽略由集群自动维护
启动高可用standalone集群
start-cluster.sh
** /etc/profile文件中新增内容:

# The external address of the host on which the JobManager runs and can be

# by specifying the --host
# In high availability mode, if you use the bin/start-cluster.sh script and setup
# the conf/masters file, this will be taken care of automatically. Yarn/Mesos

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

# For framework setups on Yarn or Mesos, 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.
#
io.tmp.dirs: /tmp/flinkio
# Specify whether TaskManager's managed memory should be allocated when starting
# up (true) or when memory is requested.
#
# We recommend to set this value to 'true' only in setups for pure batch
# processing (DataSet API). Streaming setups currently do not use the TaskManager's
# managed memory: The 'rocksdb' state backend uses RocksDB's own memory management,
# while the 'memory' and 'filesystem' backends explicitly keep data as objects
# to save on serialization cost.
#
# taskmanager.memory.preallocate: false
# 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.
#
# classloader.resolve-order: child-first
# The amount of memory going to the network stack. These numbers usually need

# Flink Cluster Security Configuration
#==============================================================================
# Kerberos authentication for various components - Hadoop, ZooKeeper, and connectors -
# may be enabled in four steps:
# 1. configure the local krb5.conf file
# 2. provide Kerberos credentials (either a keytab or a ticket cache w/ kinit)
# 3. make the credentials available to various JAAS login contexts
# 4. configure the connector to use JAAS/SASL
# The below configure how Kerberos credentials are provided. A keytab will be used instead of
# a ticket cache if the keytab path and principal are set.
# security.kerberos.login.use-ticket-cache: true
