目录
1、安装启动 oracle19c 容器
2、rpm包安装clickhouse
3、datax安装
4、datax同步
目标库根据要同步的表，按照clickhouse建表规范建表
编写json文件
编写增量同步shell脚本，加入 crond 定时任务
1、安装启动 oracle19c 容器
二、拉取镜像
docker pull registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle
三. 创建Oracle 19c镜像的容器
3.1创建目录
[root@docker ~]# mkdir /opt/oradata
[root@docker ~]# chmod -R 777 /opt/oradata/
[root@docker ~]# mkdir /opt/to_oracle
3.2 创建实例
docker run -d -it --name oracle19c -p 11521:1521 -p 5500:5500 \
-v /opt/oradata:/opt/oracle/oradata \
-v /opt/to_oracle:/home/oracle/to_oracle \
registry.cn-hangzhou.aliyuncs.com/zhuyijun/oracle:latest
3.3 查看日志
docker logs -f oracle19c
四、 修改密码
系统默认的system密码修改成oracle
docker exec oracle19c ./setPassword.sh oracle
5.1 进入容器
docker exec -it oracle19c /bin/bash
5.2 登录数据库
sqlplus sys/oracle@localhost:1521/ORCLCDB as sysdba
show pdbs;
alter session set container=ORCLPDB1;
5.4 查看数据文件位置
select file_name from dba_data_files;
5.6 创建数据表空间
create tablespace bigdata datafile '/opt/oracle/oradata/ORCLCDB/ORCLPDB1/bigdata.dbf' size 10G autoextend on;
5.7 创建用户，指定默认表空间
create user bigdata identified by bigdata default tablespace bigdata;
5.8 用户授权
grant connect,resource,dba to bigdata;
5.3 连接可拔插数据库
sqlplus /nolog
conn bigdata/bigdata@ORCLPDB1
建表、插入数据
把 create.sql insert.sql 放在 /opt/to_oracle/
SQL> @/home/oracle/to_oracle/create.sql

3、datax安装
System Requirements
JDK(1.8以上，推荐1.8)
Python(推荐Python2.6.X) 我使用的CentOS7自带的 Python 2.7.5
直接下载DataX工具包：
DataX下载地址（http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz）
