1，安装odbc

sudo yum install unixODBC unixODBC-devel mysql-connector-odbc

确认安装成功

[tidb@vm10-2-103-12 ~]$ isql --verison
unixODBC 2.3.1

确认/usr/lib64/libmyodbc9w.so存在

2，配置odbc.ini, 如无新建并保存和修改如下配置。

sudo vi /etc/odbc.ini

[mysql]
Description=MySQL test database
Trace=Yes
TraceFile=mysql_sql.log
Driver=/usr/lib64/libmyodbc9w.so
SERVER=10.2.103.12
USER=root
PASSWORD=
PORT=4100
DATABASE=test

注意：配制一个odbc.ini文件简单直接，不容易出错。

3，确认访问：

[tidb@vm10-2-103-12 ~]$ sudo vi /etc/odbc.ini
[tidb@vm10-2-103-12 ~]$ isql mysql -v
