下载安装 unixODBC，并配置 unixODBC 连接 DM 数据库
1 - 进入官网：https://www.unixodbc.org/， 选择 Download 下载软件包。
2 - 解压、安装 unixODBC
以 root 用户安装，配置，最后测试时使用 dmdba 用户
# tar -zxvf unixODBC-2.3.0.tar.gz源码安装三部曲（配置、编译、安装）：
（注：configure 时可以使用--prefix 参数指定安装路径 ./configure --prefix=/path/to/install，不指定使用默认安装路径/usr/local）
# mkdir /dm/odbc
# cd unixODBC-2.3.0/
# ./configure <===或者 --prefix=/path/to/install
# make
# make install3 - 配置驱动数据源信息
查看配置文件路径
[root@test unixODBC-2.3.0]# odbcinst -j
unixODBC 2.3.7

注意：使用 unixODBC 连接达梦数据库，需安装达梦数据库客户端（客户端可以从达梦服务器的安装目录/drivers/odbc 下拷贝，也可以单独使用达梦软件包安装客户端，默认 odbc 驱动文件位于达梦安装目录/drivers/odbc 下）。
odbcinst.ini、odbc.ini 内容参考如下：
[root@test /]# vim /etc/odbcinst.ini
[DM ODBC DRIVER]
Description = ODBC DRIVER FOR DM
Driver = /dm/dmdbms/drivers/odbc/libdodbc.so
[root@test /]# vim /etc/odbc.ini
[DM]
Description = DM ODBC DSN
Driver = DM ODBC DRIVER
SERVER = localhost
UID = SYSDBA
PWD = Dameng123
TCP_PORT = 52384 - 使用 dmdba 用户执行 isql 测试连接是否正常：
$ isql dm -v
[dmdba@test ~]$ isql dm -v
