源码安装cx_Oracle（适合离线环境）

cd ~/tools

unzip instantclient-basic-linux.x64-12.2.0.1.0.zip

mv instantclient_12_2 /opt/

export ORACLE_HOME=/opt/instantclient_12_2/

mv instantclient-sdk-linux.x64-12.2.0.1.0.zip /opt

cd /opt

unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip

这里解压会自动解压到/opt/instantclient_12_2/里

export C_INCLUDE_PATH=/opt/instantclient_12_2/sdk/include/

export LD_LIBRARY_PATH=/opt/instantclient_12_2/

ln -s /opt/instantclient_12_2/libclntsh.so.12.1 /opt/instantclient_12_2/libclntsh.so

cd ~/tools/rpmbao
