Question

我正在配置ODBC.ini文件以从Debian服务器连接到远程数据库。我的背景主要是PHP和MySQL，所以建立一个ODBC对我来说是新的，我将不胜感激。我的理解是每个DSN都需要在ODBC.ini文件中配置，我已经掌握了这些信息。

;---------------------------------------------------------------------------
; IBM INFORMIX ODBC Sample File

; File:     odbc.ini
;

[ODBC Data Sources]
Infdrv1=IBM INFORMIX ODBC DRIVER

;UNICODE=UCS-4
;
; Trace file Section
;
Trace=0
TraceFile=/tmp/odbctrace.out
InstallDir=/extra/informix
TRACEDLL=idmrs09a.so

但是，我想知道在客户端配置完成后是否有测试连接的实用程序或方法。关于如何在Windows上执行此操作似乎有相当多的信息，更不用说在Linux上了。任何帮助表示赞赏。

之前 ，只是评论。如果您想使用PHP, exists a PDO访问Informix ... ，您可以找到有关如何安装/配置here，here或此处PHP and Informix on Debian - how to install/configure the PDO <的提示/ p>

我使用“isql”命令，我用unixODBC rpm获取它（我使用opensuse发行版）。
官方网站：http://www.unixodbc.org/
有一些解释如何使用它。
您可以在Informix手册中找到更新的信息:: http://pic.dhe.ibm.com/infocenter/informix/v121/topic/com.ibm.odbc.doc/ids_odbc_057.htm

要设置Informix访问权限，我只需：

设置informix变量（需要安装csdk）

export INFORMIXDIR=/opt/informix  
export INFORMIXSERVER=ifxtest
export INFORMIXSQLHOSTS=$INFORMIXDIR/etc/sqlhosts
export PATH=$INFORMIXDIR/bin:$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$INFORMIXDIR/lib:$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:$INFORMIXDIR/lib/tools

使用所需的配置创建odbc.ini 设置DNS名称（在示例中是Infdrv1）
将驱动程序定义到安装csdk的路径定义数据库，servername，login / passwd（如果需要）
导出指向odbc.ini文件的ODBCINI变量，或为特定用户创建$ HOME / .odbc.ini。
尝试连接到正在执行的数据库：isql <dns_name> <user> <passwd>

完成上述所有配置后，这是我的测试：
