本文實例講述了python安裝oracle擴充及資料庫連線方法。分享給大家參考,如下:
下載:
cx_Oracle下載位址:http://cx-oracle.sourceforge.net/instantclient -basic
下載網址:http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html
#window環境:
python27 oracle10
需要軟體:
cx_Oracle- 5.1.2-10g.win32-py2.7.msi
instantclient-basic-win32-10.2.0.4.zip
#1. 直接雙擊msi文件,即安裝cx_Oracle;
2. 解壓縮instantclient-basic-win32-10.2.0.4.zip,將得到的.dll檔案全部拷貝到F:\Python27\Lib\site-packages目錄下
linux環境:
python26 orracle10
#需要軟體:
cx_Oracle-5.1.2-10g- py26-1.x86_64.rpm
basic-10.2.0.4.0-linux-x86_64.zip
1. rpm -ivh cx_Oracle-5.1.2-10g-py26-1.x86_64 .rpm
2.(此處參考 http://www.php.cn/)
#設定環境變數
#
vi /root/.bash_profile
增加如下兩行:export ORACLE_HOME=/usr/local/instantclient_10_2
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME
執行source /root/.bash_profile讓變更生效
cd $ORACLE_HOME ln -s libclntsh.so.x.x libclntsh.so
