FlinkX的安裝
安裝unzip：yum install unzip
1、上傳並解壓
unzip flinkx-1.10.zip -d /usr/local/soft/
2、配置環境變數
3、給bin/flinkx這個檔案加上執行許可權
chmod a+x flinkx
4、修改配置檔案，設定執行埠
vim flinkconf/flink-conf.yaml
## web服務埠，不指定的話會隨機生成一個
rest.bind-port: 8888
配置環境變數、
vim /etc/profile
FLINKX_HOME=
flinkX開源網址：https://github.com/DTStack/flinkx
FlinkX的簡單使用

FlinkX本地執行
flinkx -mode local -job flinkx3.json -pluginRoot ../syncplugins -flinkconf ../flinkconf
執行時檔案所處路徑為：/usr/local/soft/flinkx-1.10/package

- 啟動任務
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/
- 監聽日誌
flinkx 任務啟動後，會在執行命令的目錄下生成一個nohup.out檔案
tail -f nohup.out
- 通過web介面檢視任務執行情況

- 在hive中建立testflinkx資料庫，並建立student分割槽表
create database testflinkx;
use testflinkx;
CREATE TABLE `student`(
`id` string,
`name` string,
`age` string)
PARTITIONED BY (
`pt` string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY ','
