Add Oracle data source to superset,
System: Centos 7
Database: Oracle 11G
SuperSet：0.23.2
Before using the Oracle data source, you need to install the Oracle client on the server, then configure the environment variables of the dynamic library, then install the Python Oracle plug-in, and finally configure the URI of the data source through the superset console.
Step 1: Create an Oracle installation directory and extract the installation files
mkdir -p /opt/oracle
cd /opt/oracle
unzip linux.x64_11gR2_client.zip
Step 2: Install the libaio package
sudo yum install libaio
Step 3: Create a Runtime Connection for the Oracle Client
sudo sh -c "echo /opt/oracle/app/oracle/product/11.2.0/client_1 > /etc/ld.so.conf.d/oracle-instantclient.conf" sudo ldconfig
Step 4: Configure dynamic link library environment variables
export LD_LIBRARY_PATH=/opt/oracle/app/oracle/product/11.2.0/client_1:$LD_LIBRARY_PATH
Step 5: Install Oracle's python plugin
pip install cx_Oracle
Step 6: Add a data source through the console interface of SuperSet, and display "Seems OK!" through the test. The data source addition is complete!
