（1）操作系统(系统上面要安装一些必备的开发工具(比如gcc等))
linux-82:/home/PlODBC # cat/etc/SuSE-release
SUSE Linux EnterpriseServer 11 (x86_64)
VERSION = 11
PATCHLEVEL = 1
（2）安装所需的软件包
greenplum-connectivity-4.3.0.0-build-2-SuSE10-x86_64.zip
--GP官网下载，GP的JDBC和ODBC驱动
DBI-1.631.tar.gz
--DBI是数据库的通用接口
DBD-ODBC-1.48.tar.gz
--DBD是相应数据库的驱动程序unixODBC-2.2.12-204.3.1.x86_64.rpm
--unixODBC的驱动管理器
（3）将上面的包上传到搭建环境的服务器上面，比如/home/PlODBC
（1） 解压greenplum-connectivity-4.3.0.0-build-2-SuSE10-x86_64.zip
unzipgreenplum-connectivity-4.3.0.0-build-2-SuSE10-x86_64.zip
（2） 执行解压后得到greenplum-connectivity-4.3.0.0-build-2-SuSE10-x86_64.bin可执行文件
linux-82:/home/PlODBC # ./greenplum-connectivity-4.3.0.0-build-2-SuSE10-x86_64.bin

（3） 配置Greenplum DB数据库驱动
查看安装目录时，如下：
linux-82:/usr/local/greenplum-connectivity-4.3.0.0-build-2/drivers/odbc# ll
total 24
drwxr-xr-x 3 hadoop users 4096 2013-11-15 09:49 psqlodbc-08.02.0400

drwxr-xr-x 3 hadoop users 4096 2013-11-15 09:56psqlodbc-09.02.0100
我们会看到有好几个版本的驱动，我们可以选择psqlodbc-08.02.0500版本的，再查看如下目录：
linux-82:/usr/local/greenplum-connectivity-4.3.0.0-build-2/drivers/odbc/psqlodbc-08.02.0500# ll
total 48
drwxr-xr-x 3 hadoop users 4096 2013-11-15 09:51 datadirect-51sp2_64

drwxr-xr-x 4hadoop users 4096 2013-11-15 09:50unixodbc-2.2.12
同样我们可以看到驱动管理器。
鉴于GP基于Postgresql8.2版本，我们这里面选择驱动为psqlodbc-08.02.0500，驱动管理器选择为datadirect-52_64。
所以，我们修改greenplum_connectivity_path.sh文件中的内容：
GP_ODBC_DRIVER=psqlodbc-08.02.0500 --值与实际目录名称相同
GP_ODBC_DRIVER_MANAGER=datadirect-52_64 --值与实际目录名称相同
注：该文件默认权限位444，是不允许编辑的，你可以手动修改文件的权限，也可以修改整个安装目录的权限位755，如下：
chmod -R 755greenplum-connectivity-4.3.0.0-build-2
保存greenplum_connectivity_path.sh后，要记得source，使环境变量生效，如下：
source greenplum_connectivity_path.sh
（1） 直接安装RPM包
rpm -ivhunixODBC-2.2.12-204.3.1.x86_64.rpm

可以可看到unixODBC配置文件位于/etc/unixODBC下面：
linux-82:/etc/unixODBC # ll /etc/unixODBC
total 4
drwxr-xr-x 2 root root 4096 2011-06-15 00:32 ODBCDataSources

-rw-r--r-- 1 root root 02011-06-15 00:32 odbcinst.ini
（3） 编辑unixODBC的两个配置文件，如下：
linux-82:/etc/unixODBC # cat /etc/unixODBC/odbc.ini
[GreenplumDSN]
Driver =Greenplum ----值要和/etc/unixODBC/odbcinst.ini中名字一致
Trace = 1
Debug=1
Database = noas ----GP数据库名
Servername = 10.41.24.102 ----GP的IP地址
UserName = noas ----GP用户名
Password = noas ----GP用户密码
Port = 5432 ----GP访问端口号
ReadOnly = No
RowVersioning = No
DisallowPremature = No
ShowSystemTables = Yes
ShowOidColumn = No
FakeOidIndex = No
useDeclareFetch = 1
Fetch = 4096
UpdatableCursors = Yes
Protocol = 7.4-1
linux-82:/etc/unixODBC # cat /etc/unixODBC/odbcinst.ini
[Greenplum]
Description = PostgreSQL driver forGreenplum
Driver=/usr/local/greenplum-connectivity-4.3.0.0-build-2/drivers/odbc/psqlodbc-08.02.0500/unixodbc-2.2.12/psqlodbcw.so ------GP的ODBC驱动
UsageCount=1
FileUsage= 1
（4） 使用isql测试
linux-82:/etc/unixODBC # isql GreenplumDSN
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
SQL> select user;
+-----------------------------------------------------------------+
| current_user |
+-----------------------------------------------------------------+
| noas |
+-----------------------------------------------------------------+
SQLRowCount returns -1
1 rows fetched
SQL>
注：如果你在执行isql时，出现如下情况：
linux-82:/etc/unixODBC # isql GreenplumDSN
[ISQL]ERROR: Could not SQLConnect
这个问题很大情况下是你没有source文件greenplum_connectivity_path.sh导致的，执行source greenplum_connectivity_path.sh文件后，再执行就OK了，最好的办法是将source该文件加入到系统环境变量中。
（1） 解压DBI安装包
linux-82:/home/PlODBC # tar -zxvfDBI-1.631.tar.gz
（2） 查看DBI解压的目录
进入解压的目录，可以查看到Perl模块的安装说明文件INSTALL，里面有段内容为：
perl Makefile.PL
make
make test
make test TEST_VERBOSE=1 (if any of the t/* tests fail)
make install (if the tests look okay)
Perl的模块安装，基本上都是这几个步骤，test的内容不做强求，但是建议执行。
（3） 执行DBI安装
linux-82:/home/PlODBC/DBI-1.631 # perlMakefile.PL
linux-82:/home/PlODBC/DBI-1.631 # make
linux-82:/home/PlODBC/DBI-1.631 #make install
（4） 测试DBI安装是否成功
linux-82:/home/PlODBC/DBI-1.631 # perl-e ‘use DBI 1.625;‘
如果没有访问信息，则说明安装成功。
（5） 解压DBD-ODBC安装包
linux-82:/home/PlODBC # tar -zxvfDBD-ODBC-1.48.tar.gz
（6） 执行DBD-ODBC安装
perl Makefile.PL
make
make install
（7） 测试DBD-ODBC安装是否成功
linux-82:/home/PlODBC # perl -e‘use DBD::ODBC;‘
如果没有访问信息，则说明安装成功。
查看DBI整个安装信息：
linux-82:/home/PlODBC # perl -MDBI -e‘DBI->installed_versions;‘
Perl : 5.010000 (x86_64-linux-thread-multi)
OS : linux (2.6.32)
DBI : 1.631
DBD::Sponge : 12.010003
DBD::Proxy : install_driver(Proxy) failed: Can‘tlocate RPC/PlClient.pm in @INC
DBD::ODBC : 1.48
DBD::Gofer : 0.015327
DBD::File : 0.42
DBD::ExampleP : 12.014311
DBD::DBM : 0.08
可以看到DBI和DBD-ODBC都已经安装好了。
注：在编译DBD-ODBC时，如果报如下的错误：
linux-82:/home/PlODBC/DBD-ODBC-1.48 # perlMakefile.PL

I cannot find drivermanager header files. Perhaps you need to install the

The DBD::ODBC moduleneeds to link with an ODBC ‘Driver Manager‘.
(The Driver Manager, inturn, needs one or more database specific ODBC
drivers. The DBD::ODBCmodule does _not_ include any ODBC drivers!)
You need to indicate where your ODBC DriverManager is installed.
You can do this by:
o setting the ODBCHOME environment variable
o running ‘perl Makefile.PL -o odbcdir‘
o adding path to odbc_config/iodbc_configto PATH
If you do not have an ODBC Driver Manageryou should try to get hold of
the unixODBC packages for your system orbuild it from source (see
http://www.unixodbc.org). If you installdriver manager packages you
need to include the "XXX-dev"package which includes the C header files.
上面的主要问题是没有设置如下变量导致的：
export ODBCHOME=/usr/local/unixODBC
export LD_LIBRARY_PATH=/usr/local/unixODBC/lib
但是我们安装的unixODBC是RPM形式的包，安装后的目录不满足要求，所以我们需要重新编译安装unixODBC：
解压unixODBC-2.3.2.tar.gz包并安装
tar -zxvf unixODBC-2.3.2.tar.gz
./configure --prefix=/usr/local/unixODBC
make
make install
unixODBC安装好之后，设置环境变量：
export ODBCHOME=/usr/local/unixODBC
export LD_LIBRARY_PATH=/usr/local/unixODBC/lib
然后再重新安装DBD-ODBC驱动，就可以成功安装了。
同时不要忘记，将之前配置的/etc/unixODBC/odbc.ini和/etc/unixODBC/odbcinst.ini文件都拷贝到/usr/local/unixODBC/etc目录下面，因为Perl脚本将/usr/local/unixODBC/etc这里获取GP的数据库配置驱动信息。
（1） 准备perl测试脚本，如下：
