linux rails oracle 环境,在rails 4.0.0 和 ruby 2.0.0 环境下安装 oracle 64位客户端 及其适配器...

Introduction

This page explains the way to install ruby-oci8 for Oracle Instant Client.

For Oracle Full Client, look at Install for Oracle Full Client. For Windows, look at Install Binary Package unless you have a special need to compile ruby-oci8 by yourself.

Install Oracle Instant Client Packages

Donwload Instant Client Packages

Download the following packages from Oracle Technology Network.

Instant Client Package - Basic or Basic Lite

Instant Client Package - SDK

Instant Client Package - SQL*Plus

Note: use 32-bit packages for 32-bit ruby even though the OS is 64-bit.

UNIX zip packages

Unzip the packages as follows:

mkdir /opt mkdir/opt/oracle

cd /opt/oracle

unzip path/to/instantclient-basic-OS-VERSION.zip

unzip path/to/instantclient-sdk-OS-VERSION.zip

unzip path/to/instantclient-sqlplus-OS-VERSION.zip

If /opt/oracle/instantclient10_1/libclntsh.so is not found, make a symbolic link to link the library.

cd /opt/oracle/instantclient10_1

ln -s libclntsh.so.10.1 libclntsh.so

Note:

use libclntsh.sl instead of libclntsh.so on HP-UX PA-RISC.

use libclntsh.dylib instead of libclntsh.so on Mac OS X.

skip this step for AIX.

Set the library search path, whose name depends on the OS, to point to the installed directory.

OS

library search path

Linux

LD_LIBRARY_PATH

Solaris 32-bit ruby

LD_LIBRARY_PATH_32 or LD_LIBRARY_PATH

Solaris 64-bit ruby

LD_LIBRARY_PATH_64 or LD_LIBRARY_PATH

HP-UX PA-RISC 32-bit ruby

SHLIB_PATH

HP-UX PA-RISC 64-bit ruby

LD_LIBRARY_PATH

HP-UX IA64

LD_LIBRARY_PATH

Mac OS X

DYLD_LIBRARY_PATH

AIX

LIBPATH

For example: $ LDLIBRARYPATH=/opt/oracle/instantclient102 $ export LDLIBRARYPATH

Linux rpm packages

Install the downloaded packages as follows:

rpm -i path/to/oracle-instantclient-basic-VERSION-ARCH.rpm

rpm -i path/to/oracle-instantclient-devel-VERSION-ARCH.rpm

rpm -i path/to/oracle-instantclient-sqlplus-VERSION-ARCH.rpm

Set LDLIBRARYPATH to point to the directory where libclntsh.so is installed.

For example: $ LDLIBRARYPATH=/usr/lib/oracle/10.2.0.3/client/lib $ export LDLIBRARYPATH

Windows

Unzip the packages and set PATH to point to the directory where OCI.DLL is installed.

Check the environment

Oracle installation

Run the following command and confirm it works fine. If it doesn't work well, check LD_LIBRARY_PATH or PATH.

sqlplus USERNAME/PASSWORD

ruby installation

Run the following command. If it ends with "can't find header files for ruby" or "ruby: no such file to load -- mkmf (LoadError)", you need to install ruby-devel(redhat) or ruby-dev(debian/ubuntu).

ruby -r mkmf -e ""

development tools

You need a C compiler and development tools such as make or nmake. Note that they must be same with ones used to compile the ruby. For example, you need Oracle Solaris Studio, not gcc, for ruby compiled by Oracle Solaris Studio.

Installation

If you get a problem in the following steps, look at Platform Specific Issues and Report Installation Issues.

gem package

Run the following command.

gem install ruby-oci8

tar.gz package

Download the source code

Download the latest tar.gz package such as ruby-oci8 2.1.0.tar.gz, which is the latest version at the time of writing, from rubyforge.

Note: if you are using Windows and you have no special need to compile it by yourself, look at install-binary-packge.

Run make and install

UNIX or Windows(mingw32, cygwin)

gzip -dc ruby-oci8-VERSION.tar.gz | tar xvf -

cd ruby-oci8-VERSION

make

make install

note: If you use 'sudo', use it only when running 'make install'. 'sudo' doesn't pass library search path to the executing command for security reasons.

Windows(mswin32)

gzip -dc ruby-oci8-VERSION.tar.gz | tar xvf -

cd ruby-oci8-VERSION

nmake

nmake install
