FlinkX的安装

安装unzip：yum install unzip

1、上传并解压

unzip flinkx-1.10.zip -d /usr/local/soft/

2、配置环境变量

3、给bin/flinkx这个文件加上执行权限

chmod a+x flinkx

4、修改配置文件，设置运行端口

vim flinkconf/flink-conf.yaml

## web服务端口，不指定的话会随机生成一个
rest.bind-port: 8888

• 启动任务

    flinkx -mode local -job /usr/local/soft/flinkx-1.10/jsonConf/mysqlToHDFS.json -pluginRoot /usr/local/soft/flinkx-1.10/syncplugins/ -flinkconf /usr/local/soft/flinkx-1.10/flinkconf/

• 监听日志

flinkx 任务启动后，会在执行命令的目录下生成一个nohup.out文件

tail -f nohup.out

• 通过web界面查看任务运行情况

• 在hive中创建testflinkx数据库，并创建student分区表

create database testflinkx;
use testflinkx;
CREATE TABLE `student`(
  `id` string, 
  `name` string, 
  `age` string)
PARTITIONED BY ( 
  `pt` string)
ROW FORMAT DELIMITED 
  FIELDS TERMINATED BY ','

• 启动hiveserver2

# 第一种方式：
hiveserver2
# 第二种方式:
hive --service hiveserver2

• 启动任务

flinkx -mode local -job /usr/local/soft/flinkx-1.10/jsonConf/mysqlToHive.json -pluginRoot /usr/local/soft/flinkx-1.10/syncplugins/ -flinkconf /usr/local/soft/flinkx-1.10/flinkconf/
