1.软件环境
- 操作系统:ubuntu 18.04
- Apache Doris :0.15
- Postgresql数据库:oracle 19c
- UnixODBC:2.3.4
- Oracle ODBC :instantclient-odbc-linux.x64-19.13.0.0.0dbru
2.Oracle安装部署
因为是测试没有Oracle的环境,由于安装比较繁琐耗时,所以通过Docker进行快速安装部署
2.1 制作镜像
安装方法是通过官方dockerfile自己编译镜像安装,
root@iZbp1cq4g9n8chsy7hcafhZ:~# git clone https://github.com/oracle/docker-images.git Cloning into 'docker-images'... remote: Enumerating objects: 77, done. remote: Counting objects: 100% (77/77), done. remote: Compressing objects: 100% (52/52), done. remote: Total 9878 (delta 25), reused 55 (delta 23), pack-reused 9801 Receiving objects: 100% (9878/9878), 10.20 MiB | 2.47 MiB/s, done. Resolving deltas: 100% (5686/5686), done. root@iZbp1cq4g9n8chsy7hcafhZ:~# cd docker-images/OracleDatabase/SingleInstance/dockerfiles/ root@iZbp1cq4g9n8chsy7hcafhZ:~/docker-images/OracleDatabase/SingleInstance/dockerfiles# ll total 44 drwxr-xr-x 9 root root 4096 Jan 1 11:51 ./ drwxr-xr-x 7 root root 4096 Jan 1 11:51 ../ drwxr-xr-x 2 root root 4096 Jan 1 11:51 11.2.0.2/ drwxr-xr-x 2 root root 4096 Jan 1 11:51 12.1.0.2/ drwxr-xr-x 2 root root 4096 Jan 1 11:51 12.2.0.1/ drwxr-xr-x 2 root root 4096 Jan 1 11:51 18.3.0/ drwxr-xr-x 2 root root 4096 Jan 1 11:51 18.4.0/ drwxr-xr-x 2 root root 4096 Jan 1 12:04 19.3.0/ drwxr-xr-x 2 root root 4096 Jan 1 11:51 21.3.0/ -rwxr-xr-x 1 root root 7091 Jan 1 11:51 buildContainerImage.sh* ---制作镜像的命令
目前支持以上几个版本的docker安装。
我们这里要制作安装的是19.3.0这个版本
root@iZbp1cq4g9n8chsy7hcafhZ:~/docker-images/OracleDatabase/SingleInstance/dockerfiles/19.3.0# ll total 2988092 drwxr-xr-x 2 root root 4096 Jan 1 12:04 ./ drwxr-xr-x 9 root root 4096 Jan 1 11:51 ../ -rwxr-xr-x 1 root root 1044 Jan 1 11:51 checkDBStatus.sh* -rwxr-xr-x 1 root root 904 Jan 1 11:51 checkSpace.sh* -rw-r--r-- 1 root root 63 Jan 1 11:51 Checksum.ee -rw-r--r-- 1 root root 63 Jan 1 11:51 Checksum.se2 -rwxr-xr-x 1 root root 7634 Jan 1 11:51 createDB.sh* -rw-r--r-- 1 root root 9204 Jan 1 11:51 dbca.rsp.tmpl -rw-r--r-- 1 root root 6878 Jan 1 11:51 db_inst.rsp -rw-r--r-- 1 root root 4398 Jan 1 11:51 Dockerfile -rwxr-xr-x 1 root root 2712 Jan 1 11:51 installDBBinaries.sh* -rw-r--r-- 1 root root 3059705302 Apr 24 2019 LINUX.X64_193000_db_home.zip ---oracle安装介质文件 -rw-r--r-- 1 root root 2008 Jan 1 11:51 relinkOracleBinary.sh -rwxr-xr-x 1 root root 7743 Jan 1 11:51 runOracle.sh* -rwxr-xr-x 1 root root 1021 Jan 1 11:51 runUserScripts.sh* -rwxr-xr-x 1 root root 795 Jan 1 11:51 setPassword.sh* -rwxr-xr-x 1 root root 1057 Jan 1 11:51 setupLinuxEnv.sh* -rwxr-xr-x 1 root root 679 Jan 1 11:51 startDB.sh* root@iZbp1cq4g9n8chsy7hcafhZ:~/docker-images/OracleDatabase/SingleInstance/dockerfiles/19.3.0# cat Dockerfile|grep INSTALL_FILE_1 INSTALL_FILE_1="LINUX.X64_193000_db_home.zip" \ ---这里我们可以看到Oracle的安装介质文件名 COPY --chown=oracle:dba $INSTALL_FILE_1 $INSTALL_RSP $INSTALL_DB_BINARIES_FILE $INSTALL_DIR/
我们需要下载Oracle的安装介质文件
这里需要登录,下载完成之后将zip包放到这个目录下,然后执行下面命令:
./buildDockerImage.sh -v 19.3.0 -e
e表示企业版
Successfully built 701b50f5832a Successfully tagged oracle/database:19.3.0-ee Oracle Database Docker Image for 'ee' version 19.3.0 is ready to be extended: --> oracle/database:19.3.0-ee Build completed in 2624 seconds.
当出现上面的提示,就表示镜像制作完成了,剩下就是利用该镜像启动容器即可。
2.2 启动容器,安装数据库
注意:oracle 企业版的docker run的命令格式如下(XE版的都有所区别):
root@iZbp1cq4g9n8chsy7hcafhZ:~# docker run --name oracle-19c \ -p 1521:1521 -p 5500:5500 \ -e ORACLE_SID=lei \ ---这里是你安装数据的时候创建的数据库SID -e ORACLE_PDB=leipdb \ -e ORACLE_PWD=Oracle \ -v /oracle/oradata:/opt/oracle/oradata \ oracle/database:19.3.0-ee
注意:/oracle/oradata
目录权限一定要正确,在容器中oracle用户的uid是54321,所以要保证容器内的oracle用户有权限读写该目录。
注:如果"DATABASE IS READY TO USE!"提示信息,表示数据库已成功安装了。
2.3 验证Oracle安装
登陆主机或数据库进行操作
root@iZbp1cq4g9n8chsy7hcafhZ:~# docker exec -it oracle-19c /bin/bash [oracle@fa7ee1d287ee ~]$ export ORACLE_SID=LEI [oracle@fa7ee1d287ee ~]$ sqlplus / as sysdba SQL*Plus: Release 19.0.0.0.0 - Production on Sun Jan 2 02:28:55 2022 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle. All rights reserved. Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.3.0.0.0 SQL> show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 LEIPDB READ WRITE NO SQL>
至此就完成了docker安装Oracle 19c!
然后我们就可以创建数据库、创建表、导入数据进行测试
我们首先创建一个表空间,然后创建用户挂在到这个表空间下
---创建表空间 create tablespace demo1 datafile '/opt/oracle/oradata/demo1.dbf' size 200M; ---创建用户并给用户设置默认的表空间 create user C##dbuser identified by "zhangfeng" default tablespace demo1; ---给用户授权 grant connect,resource,dba to C##dbuser; grant create session to C##dbuser;
然后我们可以使用Navicat或者SQLPlus等其他客户端使用刚才创建的用户连接Oracle,去创建表,导入数据
下面是我测试的建表语句及插入的示例数据
CREATE TABLE persons( person_id NUMBER GENERATED BY DEFAULT AS IDENTITY, first_name VARCHAR2(50) NOT NULL, last_name VARCHAR2(50) NOT NULL, PRIMARY KEY(person_id) ); INSERT INTO "C##DBUSER"."PERSONS" VALUES ('1', 'zhang', 'feng'); INSERT INTO "C##DBUSER"."PERSONS" VALUES ('2', '张峰', '峰'); INSERT INTO "C##DBUSER"."PERSONS" VALUES ('3', 'zhangfeng', '峰值');
3.安装unixODBC驱动
首先我们安装unixODBC驱动、这里直接给出驱动的下载地址及安装命令
sudo wget ftp://ftp.unixodbc.org/pub/unixODBC/unixODBC-2.3.4.tar.gz tar -xvzf unixODBC-2.3.4.tar.gz cd unixODBC-2.3.4/ sudo ./configure --prefix=/usr/local/unixODBC-2.3.7 --includedir=/usr/include --libdir=/usr/lib -bindir=/usr/bin --sysconfdir=/etc make sudo make install
安装成功后,unixODBC所需的头文件都被安装到了/usr/inlucde下,编译好的库文件安装到了/usr/lib下,与unixODBC相关的可执行文件安装到了/usr/bin下,配置文件放到了/etc下。
验证安装是否成功
# odbcinst -j unixODBC 2.3.4 DRIVERS............: /etc/odbcinst.ini SYSTEM DATA SOURCES: /etc/odbc.ini FILE DATA SOURCES..: /etc/ODBCDataSources USER DATA SOURCES..: /root/.odbc.ini SQLULEN Size.......: 8 SQLLEN Size........: 8 SQLSETPOSIROW Size.: 8
4.安装Oracle ODBC驱动及测试
4.1 安装驱动
我们需要下载下面这几个安装包:
oracle-instantclient19.13-basic-19.13.0.0.0-2.x86_64.rpm oracle-instantclient19.13-devel-19.13.0.0.0-2.x86_64.rpm oracle-instantclient19.13-odbc-19.13.0.0.0-2.x86_64.rpm oracle-instantclient19.13-sqlplus-19.13.0.0.0-2.x86_64.rpm
下面是下载地址:
为了在ubuntu下可以进行安装rpm包,我们还需要安装一个alien,这是一个可以将rpm包转换成deb安装包的工具
sudo apt-get install alien
然后执行安装上面四个包
sudo alien -i oracle-instantclient19.13-basic-19.13.0.0.0-2.x86_64.rpm sudo alien -i oracle-instantclient19.13-devel-19.13.0.0.0-2.x86_64.rpm sudo alien -i oracle-instantclient19.13-odbc-19.13.0.0.0-2.x86_64.rpm sudo alien -i oracle-instantclient19.13-sqlplus-19.13.0.0.0-2.x86_64.rpm
验证我们安装的ODBC驱动动态链接库是否正确
root@iZbp1cq4g9n8chsy7hcafhZ:~/doris/be/conf# ldd /usr/lib/oracle/19.13/client64/lib/libsqora.so.19.1 linux-vdso.so.1 (0x00007ffefef27000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f43e80b0000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f43e7f61000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f43e7f3e000) libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007f43e7f21000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f43e7f16000) libaio.so.1 => /lib/x86_64-linux-gnu/libaio.so.1 (0x00007f43e7f11000) libresolv.so.2 => /lib/x86_64-linux-gnu/libresolv.so.2 (0x00007f43e7ef3000) libclntsh.so.19.1 => /usr/lib/oracle/19.13/client64/lib/libclntsh.so.19.1 (0x00007f43e3d6f000) libclntshcore.so.19.1 => /usr/lib/oracle/19.13/client64/lib/libclntshcore.so.19.1 (0x00007f43e37cb000) libodbcinst.so.2 => /usr/local/lib/libodbcinst.so.2 (0x00007f43e37b3000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f43e35c1000) /lib64/ld-linux-x86-64.so.2 (0x00007f43e8379000) libnnz19.so => /usr/lib/oracle/19.13/client64/lib/libnnz19.so (0x00007f43e2f4a000) libltdl.so.7 => /lib/x86_64-linux-gnu/libltdl.so.7 (0x00007f43e2f3d000)
4.2 配置环境变量
sudo vi ~/.bashrc
加入下面的内容
export ORACLE_HOME=/usr/lib/oracle/19.13/client64 export TNS_ADMIN=$ORACLE_HOME/network/admin export LD_LIBRARY_PATH=$ORACLE_HOME/lib export ORACLE_SID=LEI export PATH=$ORACLE_HOME/bin:$PATH
4.3 配置tnsnames.ora文件
cd /usr/lib/oracle/19.13/client64 mkdir -p network/admin vi tnsnames.ora
加入下面的内容(注意修改成自己的,这里是示例)
demo = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.192.81)(PORT = 1521)) ) (CONNECT_DATA = ( SERVICE_NAME = LEI) ) )
注意
- 将HOST、PORT换成你自己的
- SERVICE_NAME :这个是我们启动Oracle docker的时候设置的ORACLE_SID
4.4 配置odbcinst.ini
这里使用RPM包安装的额ODBC驱动动态链接库在
/usr/lib/oracle/19.13/client64/lib/
目录下
root@iZbp1cq4g9n8chsy7hcafhZ:~/instantclient_21_4# ll /usr/lib/oracle/19.13/client64/lib/ total 236232 drwxr-xr-x 3 root root 4096 Jan 2 11:04 ./ drwxr-xr-x 5 root root 4096 Jan 1 19:47 ../ -rw-r--r-- 1 root root 342 Nov 27 02:41 glogin.sql lrwxrwxrwx 1 root root 21 Jan 1 19:43 libclntshcore.so -> libclntshcore.so.19.1* -rwxr-xr-x 1 root root 8057664 Nov 27 02:39 libclntshcore.so.19.1* lrwxrwxrwx 1 root root 17 Jan 1 19:43 libclntsh.so -> libclntsh.so.19.1* lrwxrwxrwx 1 root root 17 Jan 1 19:43 libclntsh.so.10.1 -> libclntsh.so.19.1* lrwxrwxrwx 1 root root 17 Jan 1 19:43 libclntsh.so.11.1 -> libclntsh.so.19.1* lrwxrwxrwx 1 root root 17 Jan 1 19:43 libclntsh.so.12.1 -> libclntsh.so.19.1* lrwxrwxrwx 1 root root 17 Jan 1 19:43 libclntsh.so.18.1 -> libclntsh.so.19.1* -rwxr-xr-x 1 root root 81679160 Nov 27 02:39 libclntsh.so.19.1* -rwxr-xr-x 1 root root 3642520 Nov 27 02:39 libipc1.so* -rwxr-xr-x 1 root root 478728 Nov 27 02:39 libmql1.so* -rwxr-xr-x 1 root root 5831752 Nov 27 02:39 libnnz19.so* -rwxr-xr-x 1 root root 2342024 Nov 27 02:39 libocci.so.19.1* -rwxr-xr-x 1 root root 130543568 Nov 27 02:39 libociei.so* -rwxr-xr-x 1 root root 153464 Nov 27 02:39 libocijdbc19.so* -rwxr-xr-x 1 root root 116376 Nov 27 02:39 liboramysql19.so* -rwxr-xr-x 1 root root 1660776 Nov 27 02:41 libsqlplusic.so* -rwxr-xr-x 1 root root 1572432 Nov 27 02:41 libsqlplus.so* -rwxr-xr-x 1 root root 1070192 Nov 27 02:41 libsqora.so.19.1* ---这里是要使用的ODBC动态链接库 drwxr-xr-x 3 root root 4096 Jan 1 19:43 network/ -rw-r--r-- 1 root root 4355723 Nov 27 02:39 ojdbc8.jar -rw-r--r-- 1 root root 313026 Nov 27 02:41 ottclasses.zip -rw-r--r-- 1 root root 37519 Nov 27 02:39 xstreams.jar
编辑/etc/odbcinst.ini,在最后加上下面的内容
[Oracle 19 ODBC driver] Description = Oracle ODBC driver for Oracle 19 Driver = /usr/lib/oracle/19.13/client64/lib/libsqora.so.19.1 Setup = FileUsage = CPTimeout = CPReuse =
配置odbc.ini,在最后加上下面的内容
[oracle] Driver = Oracle 19 ODBC driver ---这里的名称是上面odbcinst.ini里oracle部分用[]括起来的内容 ServerName =172.16.192.81:1521/LEI --这里是你的oracle数据ip地址,端口及SID UserID = C##dbuser --这里是我们上面创建的用户名 Password = zhangfeng --密码
验证ODBC
isql oracle +---------------------------------------+ | Connected! | | | | sql-statement | | help [tablename] | | quit | | | +---------------------------------------+
显示一切正常
5.Apache Doris Oracle外表验证
5.1 修改配置
修改BE节点conf/odbcinst.ini文件,加入刚才/etc/odbcinst.ini添加的一样内容,并删除原先的Oracle配置,加上你刚才安装的,如下:
[Oracle 19 ODBC driver] Description = Oracle ODBC driver for Oracle 19 Driver = /usr/lib/oracle/19.13/client64/lib/libsqora.so.19.1
5.2 验证
创建oracle的ODBC Resource
CREATE EXTERNAL RESOURCE `oracle_19` PROPERTIES ( "host" = "172.16.192.81", "port" = "1521", "user" = "C##dbuser", "password" = "zhangfeng", "database" = "LEI", --这里是你的数据库示例名称,也就是我们在docker启动时的ORACLE_SID "driver" = "Oracle 19 ODBC driver", ---这里的名称一定和你在be odbcinst.ini里的oracle部分的[]里的内容一样,重要 "odbc_type" = "oracle", "type" = "odbc_catalog" );
创建ODBC外表
CREATE EXTERNAL TABLE `oracle_odbc` ( person_id int, first_name VARCHAR(50) NOT NULL, last_name VARCHAR(50) NOT NULL ) ENGINE=ODBC COMMENT "ODBC" PROPERTIES ( "odbc_catalog_resource" = "oracle_19", "database" = "LEI", "table" = "persons" );
下面我们看执行结果
mysql> CREATE EXTERNAL RESOURCE `oracle_19` -> PROPERTIES ( -> "host" = "172.16.192.81", -> "port" = "1521", -> "user" = "C##dbuser", -> "password" = "zhangfeng", -> "database" = "LEI", -> "driver" = "Oracle 19 ODBC driver", -> "odbc_type" = "oracle", -> "type" = "odbc_catalog" -> ); Query OK, 0 rows affected (0.01 sec) mysql> mysql> CREATE EXTERNAL TABLE `oracle_odbc` ( -> person_id int, -> first_name VARCHAR(50) NOT NULL, -> last_name VARCHAR(50) NOT NULL -> ) ENGINE=ODBC -> COMMENT "ODBC" -> PROPERTIES ( -> "odbc_catalog_resource" = "oracle_19", -> "database" = "LEI", -> "table" = "persons" -> ); Query OK, 0 rows affected (0.01 sec) mysql> select * from oracle_odbc; +-----------+------------+-----------+ | person_id | first_name | last_name | +-----------+------------+-----------+ | 1 | zhang | feng | | 2 | 张峰 | 峰 | | 3 | zhangfeng | 峰值 | +-----------+------------+-----------+ 3 rows in set (0.06 sec)
OK一切正常,正常情况下,Oracle ODBC驱动只要你的数据库版本和你的ODBC驱动版本(大版本号对上就行)一致,就基本不会出问题。
