cx_Oracle安装

已经先通过 anaconda 安装 了Python 2.7 （不想一个包一个包的安装 ，追求效率）

由于需要监控oracle数据库相关信息，打算通过python连接Oralce,采用cx_oracle方法

通过官方下载http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

instantclient-basic-linux.x64-11.2.0.4.0.zip

instantclient-sdk-linux.x64-11.2.0.4.0.zip

把两个压缩文件传至服务器 /tmp目录下

#unzip instantclient-basic-linux.x64-11.2.0.4.0.zip 

#unzip instantclient-sdk-linux.x64-11.2.0.4.0.zip

# mv instantclient_11_2 /opt/

cp /opt/instantclient_11_2/* /usr/lib/    #偷懒，少配下环境变量

#vi /etc/profile

export ORACLE_HOME=/opt/instantclient_11_2
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME:$ORACLE_HOME/sdk

保存退出

source /etc/profile

然pip install cx_Oracle

cd /opt/instantclient_11_2

ln -s libclntsh.so.11.1 libclntsh.so

再次安装即可
