CentOS下 Apache Doris Oracle ODBC

作者: 张家锋 | 来源:发表于2022-01-10 09:40 被阅读0次

    1.软件环境

    1. 操作系统：CentOS 7.8

    2. Apache Doris ：0.15

    3. Postgresql数据库：oracle 19c

    4. UnixODBC：2.3.1

    5. 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,下面给出各个版本的Docker镜像地址

    2.1 Oracle 21C

    # 从Docker hub下载，网络不好时，一般比较慢 
docker pull lhrbest/oracle21c_ee_db_21.3.0.0 
# 可以选择从阿里云下载 
docker pull registry.cn-hangzhou.aliyuncs.com/lhrbest/oracle21c_ee_db_21.3.0.0 
# 从阿里云下载后可以tag成如下形式 
docker tag registry.cn-hangzhou.aliyuncs.com/lhrbest/oracle21c_ee_db_21.3.0.0 lhrbest/oracle21c_ee_db_21.3.0.0

    启动容器

    
# 1、创建容器 
docker run -d --name lhroracle21c -h lhroracle21c \
-p 5510:5500 -p 55100:5501 -p 1530:1521  -p 3400:3389 \
-v /sys/fs/cgroup:/sys/fs/cgroup \
--privileged=true lhrbest/oracle21c_ee_db_21.3.0.0 \
/usr/sbin/init 
# 2、进入容器 
docker exec -it lhroracle21c bash 
# 3、启动监听和数据库 
su - oracle 
sas 
startup 
lsnrctl start

    2.2 Oracle 19C

    请参照：https://mp.weixin.qq.com/s/R5o3BQwj7q68OyYJg1JUjQ

    2.3 Oracle 18C

    ## 拉取镜像
docker pull registry.cn-hangzhou.aliyuncs.com/zhengqing/oracle18c
## 运行容器
docker run -d --name oracle18c -p 1521:1521 registry.cn-hangzhou.aliyuncs.com/zhengqing/oracle18c

    2.4 Oracle 12C

    ##拉取镜像
docker pull quay.io/maksymbilenko/oracle-12c
##运行容器
docker run -d -p 8080:8080 -p 1521:1521 -v /my/oracle/data:/u01/app/oracle quay.io/maksymbilenko/oracle-12c

    2.5 Oracle 11g

    ##拉取镜像
docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
##运行容器
docker run -d -p 1521:1521 --name oracle11g registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g

    3.安装unixODBC驱动

    首先我们安装unixODBC驱动、这里直接给出驱动的安装命令

    yum install unixODBC unixODBC-devel libtool-ltdl libtool-ltdl-devel

    安装完成之后执行odbcinst -j,看到下面信息说明安装成功

    #odbcinst -j
unixODBC 2.3.1
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：

    https://download.oracle.com/otn_software/linux/instantclient/1913000/oracle-instantclient19.13-sqlplus-19.13.0.0.0-2.x86_64.rpm
https://download.oracle.com/otn_software/linux/instantclient/1913000/oracle-instantclient19.13-devel-19.13.0.0.0-2.x86_64.rpm
https://download.oracle.com/otn_software/linux/instantclient/1913000/oracle-instantclient19.13-odbc-19.13.0.0.0-2.x86_64.rpm
https://download.oracle.com/otn_software/linux/instantclient/1913000/oracle-instantclient19.13-basic-19.13.0.0.0-2.x86_64.rpm

    然后执行安装上面四个包

    rpm -ivh  oracle-instantclient19.13-basic-19.13.0.0.0-2.x86_64.rpm
rpm -ivh  oracle-instantclient19.13-devel-19.13.0.0.0-2.x86_64.rpm
rpm -ivh  oracle-instantclient19.13-odbc-19.13.0.0.0-2.x86_64.rpm
rpm -ivh  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

 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 = 172.28.7.211)(PORT = 1521))
 )
 (CONNECT_DATA =
 (  SERVICE_NAME = LEI)
 )
 )

    注意

    1. 将HOST、PORT换成你自己的

    2. 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/

-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。

    6.Oracle 各个版本和ODBC驱动程序的对应关系

    这个同样适用于Ubuntu操作系统下

    Oracle版本 Oracle ODBC版本
    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production oracle-instantclient19.13-odbc-19.13.0.0.0
    Oracle Database 12c Standard Edition Release 12.2.0.1.0 - 64bit Production oracle-instantclient19.13-odbc-19.13.0.0.0
    Oracle Database 18c Enterprise Edition Release 18.0.0.0.0 - Production oracle-instantclient19.13-odbc-19.13.0.0.0
    Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production oracle-instantclient19.13-odbc-19.13.0.0.0
    Oracle Database 21c Enterprise Edition Release 21.0.0.0.0 - Production oracle-instantclient19.13-odbc-19.13.0.0.0
