FlinkX安装及使用
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
FlinkX的简单使用

- 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/
