Question

我正在尝试使用pyodbc连接到数据库，以下代码在Windows上工作正常，尝试在linux上运行相同的错误如下，有人可以在这里提出错误以及如何修复它吗？

import pypyodbc as pyodbc
component_id=argv[1]
print "COMPONENT ID: " + component_id
server_name='odsdb.company.com'
database_name='ODS'
cnx = pyodbc.connect("DRIVER={SQL Server};SERVER="+server_name+";DATABASE="+database_name)
db_cursor=cnx.cursor()

vi /etc/odbcinst.ini

[PostgreSQL ANSI]
Description             = PostgreSQL ODBC driver (ANSI version)
Driver          = psqlodbca.so
Setup           = libodbcpsqlS.so
Debug           = 0
CommLog         = 1
UsageCount              = 1

[PostgreSQL Unicode]
Description             = PostgreSQL ODBC driver (Unicode version)
Driver          = psqlodbcw.so
Setup           = libodbcpsqlS.so
Debug           = 0
CommLog         = 1
UsageCount              = 1

错误： -

  File "build_ver.py", line 11, in <module>
    cnx = pyodbc.connect("DRIVER={SQL Server};SERVER="+server_name+";DATABASE="+database_name)
  File "/usr/local/lib/python2.7/dist-packages/pypyodbc.py", line 2434, in __init__

sudo gedit /etc/postgresql/9.3/main/postgresql.conf。

取消注释并将listen_addresses从localhost更改为*

下一步：

`sudo gedit /etc/postgresql/9.3/main/pg_hba.conf`

更改127.0.0.1/32 to 0.0.0.0/0 在行：

 `host    all             all             127.0.0.1/32            trust`

linux上的pyodbc连接失败
