调用python时报的错误：
cx_Oracle.DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library: "libclntsh.so: cannot open shared object file: No such file or directory". See https://cx-oracle.
安装oracle客户端：
rpm -ivh oracle-instantclient12.2-basic-12.2.0.1.0-1.x86_64.rpm
rpm -ivh oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm
[root@oracletest01 home]# find / -name client64
/usr/lib/oracle/12.2/client64
[root@oracletest01 home]# vim /etc/ld.so.conf
将/usr/lib/oracle/12.2/client64/lib加进去
[root@oracletest01 home]# more /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/lib/oracle/12.2/client64/lib
使配置生效：
[root@oracletest01 home]# ldconfig
