1、检查是否安装了unixODBC

[root@a]# odbcinst -j
unixODBC 2.3.1
DRIVERS............: /etc/odbcinst.ini
SYSTEM DATA SOURCES: /etc/odbc.ini
FILE DATA SOURCES..: /etc/ODBCDataSources
USER DATA SOURCES..: /etc/odbc.ini
SQLULEN Size.......: 8
SQLLEN Size........: 8
SQLSETPOSIROW Size.: 8

2、如未安装，进行安装

rpm -ivh unixODBC-2.2.14-1.x86_64.rpm
rmp -ivh unixODBC-devel-2.2.14-1.x86_64.rpm

3、安装CSDK, 路径是/opt/gbasecsdk

tar -xf clientsdt_x.x.x_x86_64.tar -C csdk
cd csdk;./installclientsdk -i silent -DLICENSE_ACCEPTED=TRUE -DUSER_INSTALL=/opt/gbasecsdk

4、编写实例的sqlhosts文件, 文件名称sqlhosts.odbc

gbase01 onsoctcp 192.168.1.10 9088

5、配置环境变量文件profile.odbc

export GBASEDBTDIR=/opt/gbasecsdk
export LD_LIBRARY_PATH=$GBASEDBTDIR/lib:$GBASEDBTDIR/lib/cli:$GBASEDBTDIR/lib/esql
export GBASEDBTSQLHOSTS=$GBASEDBTDIR/etc/sqlhosts.odbc
export ODBCINI=/etc/odbc.ini

执行环境文件，使环境变量在当前连接生效

source profile.odbc

6、修改CSDK安装路径下etc/odbc.ini 并替换到/etc/odbc.ini --示例见步骤9

7、修改CSDK安装路径下etc/odbcinst.ini 并替换到/etc/odbcinst.ini --示例见步骤10

8、使用isql连接数据库实例(gbaseserver1是DSN)

[root@localhost FTS_V1.0]# isql gbaseserver1 -v
+---------------------------------------+
| Connected!                            |
|                                       |
| sql-statement                         |
| help [tablename]                      |
| quit                                  |
|                                       |
+---------------------------------------+
