在 CentOS 上安装 cx_Oracle

install-cx_Oracle.sh

# 从 Oracle 官方网站下载下列文件：
#
#    oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm
#    oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm
#    oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64.rpm


# 安装 Oracle 客户端
rpm -ivh oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm 
rpm -ivh oracle-instantclient11.2-devel-11.2.0.3.0-1.x86_64.rpm
#:::: [可选] sqlplus 不是必须的，但可以方便测试 Oracle
rpm -ivh oracle-instantclient11.2-sqlplus-11.2.0.3.0-1.x86_64.rpm

# 导入环境变量
export LD_LIBRARY_PATH="/usr/lib/oracle/11.2/client64/lib:${LD_LIBRARY_PATH}"
export ORACLE_HOME="/usr/lib/oracle/11.2/client64/lib"


# 建立到 ORACLE_HOME 的符号链接， 避免出现 "cannot locate Oracle include files" 错误
mkdir /usr/lib/oracle/11.2/client64/lib/sdk
ln -s /usr/include/oracle/11.2/client64 /usr/lib/oracle/11.2/client64/lib/sdk/include
 
# 开始安装 cx_Oracle
cd /path/to/cx_Oracle.xx.xx     # 进入 cx_Oracle 安装包的目录
python setup.py build
python setup.py install
# 临时测试是否安装成功
python -c "import cx_Oracle"
