cx_Oracle python模块安装

1. 需要从oracle网站下载一下两个包

instantclient-basic-linux.x64-11.2.0.4.0.zip

instantclient-sdk-linux.x64-11.2.0.4.0.zip

2. 下载后解压到某目录下，如：/oracle

3. 根据解压后的 BUILD.txt 步骤进行配置：

　　3.1

 cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs
ORACLE_HOME=/oracle/instantclient_11_2
PATH=$PATH:$HOME/bin:$ORACLE_HOME
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME:$ORACLE_HOME/sdk
export LD_LIBRARY_PATH
export PATH

配置bash_profile

　　3.2

　　　　python setup.py build
　　　　python setup.py install

3.3如果出现如下错误，则需要安装 python-devel-2.6.6-64.el6.x86_64
