Linux下Python访问SQLServer
以root权限操作
1.安装unixODBC 【下载地址http://www.unixodbc.org/】
sh configure --prefix=/usr/local/unixODBC
make
make install
2.安装freetds 【下载地址http://www.freetds.org/software.html】
sh configure -prefix=/usr/local/freetds --with-unixodbc=/usr/local/unixODBC /
-with-tdsver=8.0 -enable-msdblib -enable-dbmfix -with-gnu-ld -enable-shared -enable-static
make
make install
注：指明--with-unixodbc=/usr/local/unixODBC可以生成libtdsodbc.so
3.配置unixODBC
进入/usr/local/unixODBC
创建文件tds.driver.template
[TDS]
Description = FreeTDS Driver for Linux & MSSQL on Win32
Driver = /usr/local/freetds/lib/libtdsodbc.so
Setup = /usr/local/freetds/lib/libtdsS.so
保存后执行命令
bin/odbcinst -i -d -f tds.driver.template
创建文件tds.datasource.template
[my_data]
Description = Connection to windows virtual machine
Driver = TDS
Trace = No
Database = aa
Server = 192.168.7.3
Port = 1433
TDS_Version = 8.0
保存后执行命令
bin/odbcinst -i -s -l -f tds.datasource.template
4.测试freetds和unixODBC
进入/usr/local/freetds/目录下
执行命令
bin/tsql -H192.168.7.3 -p1433 -Usa -Padmin1234
1>use aa
2>select * from sysfiles
3>go
再进入
/usr/local/unixODBC
执行命令
bin/isql my_data sa admin1234
SQL>select * from sysfiles
5.安装pyODBC 【下载地址http://code.google.com/p/pyodbc/】
首先安装python2.4.4版，步骤：
./configure
make
make install
然后编译安装
python setup.py install
注：如果编译出错，请
cp /usr/local/unixODBC/include/* /usr/include/
cp /usr/local/unixODBC/lib/* /usr/lib/
然后再运行
6.python测试代码
import pyodbc
conn = pyodbc.connect("DSN=my_data;UID=sa;PWD=admin1234;DATABASE=aa;")
sql = 'select * from sysfiles'
cursor = conn.cursor()
cursor.execute(sql)
rs = cursor.fetchall()
if len(rs) > 0:
for i in range(0, len(rs)):
row = rs[i]
print row[0]
cursor.close()
conn.close()
*7.如果其他账户下使用pyodbc
将第5步生成的文件pyodbc.so复制到zenoss的python目录下
cp /usr/local/lib/python2.4/site-packages/pyodbc.so /opt/zenoss/lib/python2.4/site-packages/
【pyodbc.so可能位于/usr/lib/python2.4/site-packages/目录下】
这样就可以zenoss用户使用pyodbc了
