应用访问oracle数据库是通过oracle客户端来代理访问的,所以必须先得在操作系统全局安装oracle客户端程序
访问orale客户端下载页面下载orale数据库客户端程序
客户端包名称类似instantclient-basic-linux.x64-12.2.0.1.0.zip
# 复制到
cp instantclient-basic-linux.x64-12.2.0.1.0.zip /opt/oracle/
cd /opt/oracle/
# 解压
unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
cd /opt/oracle/instantclient_12_2
# 创建软链
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so
# 安装依赖
sudo yum install libaio
sudo sh -c "echo /opt/oracle/instantclient_12_2 > /etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig
export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2:$LD_LIBRARY_PATH
