配置oracle数据库
下载 instantclient-sdk-linux32-11.2.0.2.0
     instantclient-basic-linux32-11.2.0.2.0(http://download.oracle.com/otn/linux/instantclient/112020/instantclient-basic-linux32-11.2.0.2.0.zip)
     ruby-oci8-2.0.4.gem
创建目录(随便放哪都一样，关键最后指定环境变量就行)

sudo mkdir /opt/orcle

进入目录

cd /opt/oracle

unzip /#之前下的三个文件的路径/to/instantclient-basic-linux32-11.2.0.2.0.zip
unzip /#之前下的三个文件的路径/to/instantclient-sdk-linux32-11.2.0.2..zip

进入解压的文件

cd /opt/oracle/instantclient11_2
sudo ln -s libclntsh.so.11.1 libclntsh.so

  # 如果不是这个版本，会有错误提示的正确版本

设置环境变量

export LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2

进入之前下载的三个文件目录下

cd ~/Downloads
gem install ruby-oci8-2.0.4.gem
