  • Centos linux 7.6.1810 （2台，A主机，B主机）
  • Oracle 11.2.0.4（A主机安装）
  • Kafka 2.13-2.6.0 （B主机安装）
  • kafka-connect-oracle-master （B主机安装，开源程序，用于同步Oracle数据到kafka）
  • apache-maven 3.6.3 （B主机安装，kafka-connect-oracle-master 的打包工具）
  • jdk-8u261-linux-x64.rpm （B主机安装）

下载地址

  • Cenos 和Oracle 和 JDK 自行到官网下载
  • Kafka Http://kafka.apache.org/downloads

  • Kafka Connect Oracle    https://GitHub.com/tianxiancode/kafka-connect-oracle
  • apache-maven 3.6.3 http://maven.apache.org/download.cgi

实施过程

Oracle主机（A）配置

Oracle实例配置项：

  • 开启归档日志
  • 开启附加日志
  • 创建kafka-connect-oracle-master连接用户
  • 创建测试数据生成用户及测试表
--开启归档日志
sqlplus / as sysdba    
SQL>shutdown immediate
SQL>startup mount
SQL>alter database arcHivelog;
SQL>alter database open;
--开启附加日志
SQL>alter database add supplemental log data (all) columns;
--创建kafka-connect-oracle-master连接用户
create role logmnr_role;
grant create session to logmnr_role;
grant  execute_catalog_role,select any transaction ,select any dictionary to logmnr_role;
create user kminer identified by kminerpass;
grant  logmnr_role to kminer;
alter user kminer quota unlimited on users;
--创建测试数据生成用户及测试表
create tablespace test_date datafile '/u01/app/oracle/oradata/zzsrc/test_date01.dbf' size 100M autoextend on next 10M;
create user whtest identified by whtest default tablespace test_date;
grant connect,resource to whtest;
grant execute on dbms_scheduler to whtest;
grant execute on dbms_random to whtest;
grant   create  job  to  whtest;
create table t1 (
id int ,
name char(10),
createtime date default sysdate
);
alter table WHTEST.T1  add constraint PK_ID_T1 primary key (ID)  using index   tablespace TEST_DATE;

create table t2 (
id int ,
name char(10),
createtime date default sysdate
);
alter table WHTEST.T2  add constraint PK_ID_T2 primary key (ID)  using index   tablespace TEST_DATE;
create table t3 (
id int ,
name char(10),
createtime date default sysdate
);
alter table WHTEST.T3  add constraint PK_ID_T3 primary key (ID)  using index   tablespace TEST_DATE;
begin
dbms_scheduler.create_job(
job_name=> 't1_job',
job_type=> 'PLSQL_BLOCK',
job_action =>'declare
v_id int;
v_name char(10);
begin
  for i in 1..10 loop
    v_id := round(dbms_random.value(1,1000000000));
    v_name :=round(dbms_random.value(1,1000000000));
    insert into whtest.t1 (id,name)values(v_id,v_name);
  end loop;
end;',
enabled=>true,
repeat_interval=>'sysdate + 5/86400',
comments=>'insert into t1 every 5 sec');
end;
/ 

begin
dbms_scheduler.create_job(
job_name=> 't2_job',
job_type=> 'PLSQL_BLOCK',
job_action =>'declare
v_id int;
v_name char(10);
begin
  for i in 1..10 loop
    v_id := round(dbms_random.value(1,1000000000));
    v_name :=round(dbms_random.value(1,1000000000));
    insert into whtest.t2 (id,name)values(v_id,v_name);
  end loop;
end;',
enabled=>true,
repeat_interval=>'sysdate + 5/86400',
comments=>'insert into t1 every 5 sec');
end;
/ 

begin
dbms_scheduler.create_job(
job_name=> 't3_job',
job_type=> 'PLSQL_BLOCK',
job_action =>'declare
v_id int;
v_name char(10);
begin
  for i in 1..10 loop
    v_id := round(dbms_random.value(1,1000000000));
    v_name :=round(dbms_random.value(1,1000000000));
    insert into whtest.t3 (id,name)values(v_id,v_name);
  end loop;
end;',
enabled=>true,
repeat_interval=>'sysdate + 5/86400',
comments=>'insert into t3 every 5 sec');
end;
/ 
--JOB创建之后，暂时先diable，待kafka配置完成之后再enable
exec DBMS_SCHEDULER.DISABLE('T1_JOB');
exec DBMS_SCHEDULER.DISABLE('T2_JOB');
exec DBMS_SCHEDULER.DISABLE('T3_JOB');

exec DBMS_SCHEDULER.ENABLE('T1_JOB');
exec DBMS_SCHEDULER.ENABLE('T2_JOB');
exec DBMS_SCHEDULER.ENABLE('T3_JOB');

Kafka主机（B）配置

​ 将下载好的Kafka 2.13-2.6.0 、kafka-connect-oracle-master、apache-maven 3.6.3、JDK 1.8.0上传至B主机/soft目录待使用。

主机hosts文件添加解析

[root@softdelvily ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.20.44 softdelvily localhost

安装JDK

[root@softdelvily soft]# rpm -ivh jdk-8u261-linux-x64.rpm 
warning: jdk-8u261-linux-x64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

配置apache-maven工具

​ 将apache-maven-3.6.3-bin.tar.gz解压至/usr/local目录，并设置相应的/etc/profile环境变量。

[root@softdelvily soft]# tar xvf apache-maven-3.6.3-bin.tar.gz -C /usr/local/
apache-maven-3.6.3/README.txt
apache-maven-3.6.3/LICENSE
.....
[root@softdelvily soft]# cd /usr/local/

drwxr-xr-x. 2 root root   6 Apr 11  2018 bin
.....
[root@softdelvily local]# vi /etc/profile
.......
##添加如下环境变量
MAVEN_HOME=/usr/local/apache-maven-3.6.3
export MAVEN_HOME
export PATH=${PATH}:${MAVEN_HOME}/bin
[root@softdelvily local]# source /etc/profile
[root@softdelvily local]# mvn -v

OS name: "linux", version: "3.10.0-957.el7.x86_64", arch: "amd64", family: "unix"

配置Kafka 2.13-2.6.0

​ 解压Kafka 2.13-2.6.0 至/usr/local目录。

[root@softdelvily soft]# tar xvf kafka_2.13-2.6.0.tgz -C /usr/local/
kafka_2.13-2.6.0/
kafka_2.13-2.6.0/LICENSE

drwxr-xr-x. 6 root root 89 Jul 29 02:23 kafka_2.13-2.6.0
.....

​ 开启kafka，并创建对应同步数据库过的topic

--1、session1 启动ZK
[root@softdelvily kafka_2.13-2.6.0]# cd /usr/local/kafka_2.13-2.6.0/bin/
[root@softdelvily bin]# ./ZooKeeper-server-start.sh ../config/zookeeper.properties

--2、session2 启动kafka
[root@softdelvily kafka_2.13-2.6.0]# cd /usr/local/kafka_2.13-2.6.0/bin/
[root@softdelvily bin]# ./kafka-server-start.sh ../config/server.properties
--3、session3 创建cdczztar
[root@softdelvily kafka_2.13-2.6.0]# cd /usr/local/kafka_2.13-2.6.0/bin/
[root@softdelvily bin]# ./kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic cdczztar
Created topic cdczztar.
[root@softdelvily bin]# ./kafka-topics.sh --zookeeper localhost:2181 --list
__consumer_offsets
cdczztar

配置kafka-connect-oracle-maste

解压kafka-connect-oracle-master至/soft目录，并配置相应config文件，然后使用maven工具编译程序。

--解压zip包
[root@softdelvily soft]# unzip kafka-connect-oracle-master.zip 
[root@softdelvily soft]# ll

​ 将如下文件复制到kafka工作目录。

  • 复制kafka-connect-oracle-1.058.jar 和 lib/ojdbc7.jar 到$KAFKA_HOME/lib
  • 复制config/OracleSourceConnector.properties 文件到$KAFKA_HOME/config
[root@softdelvily config]# cd /soft/kafka-connect-oracle-master/target/
[root@softdelvily target]# cp kafka-connect-oracle-1.0.68.jar /usr/local/kafka_2.13-2.6.0/libs/
[root@softdelvily lib]# cd /soft/kafka-connect-oracle-master/lib
[root@softdelvily lib]# cp ojdbc7.jar /usr/local/kafka_2.13-2.6.0/libs/
[root@softdelvily lib]# cd /soft/kafka-connect-oracle-master/config/
[root@softdelvily config]# cp OracleSourceConnector.properties /usr/local/kafka_2.13-2.6.0/config/

启动kafka-connect-oracle

[root@softdelvily kafka_2.13-2.6.0]# cd /usr/local/kafka_2.13-2.6.0/bin/
[root@softdelvily bin]# ./connect-standalone.sh ../config/connect-standalone.properties ../config/OracleSourceConnector.properties

出现类似记录，表明同步成功，数据以key:value的形式输出。
