本人装的是Version 11.2.0.4.0 ，所以一下都是以Version 11.2.0.4.0 为例子，系统是CentOS 7.3
1、https://www.coder4.com/archives/1453
1、首先下载好必备的包
http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html
instantclient-basic-linux.x64-11.2.0.4.0.zip （这个我用到了，这个和下面的是一样的，应该不用也可以，由于下面要用到这个解压出来的文件，所以就没去另外琢磨了。）
oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm
2、
安装alien
yum -y install alien (非root请加权限，下同)
将rmp转为deb
alien ./oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
alien ./oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm
安装转换完的deb，如没有dpkg，请自行安装
dpkg -i ./oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.deb
dpkg -i ./oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.deb
我安装好的位置分别在（文件夹名可能不同）
/usr/lib/oracle/11.2/client64/lib
/usr/include/oracle/11.2/client64
3、设置环境变量（我的是zsh,关于ohmyzsh下一篇写，注意不要乱复制看好自己的路径）
vim
~
/
.
zshrc(如果是bash就是bashrc了)
export
LD_LIBRARY_PATH
=
$
LD_LIBRARY_PATH
:
/
usr
/
lib
/
oracle
/
11.2
/
client64
/
lib
4、安装配置OCI（根据自己的自行修改）
./configure --with-oracle-lib-path=/usr/lib/oracle/11.2/client64/lib --with-oracle-headers-path=/usr/include/oracle/11.2/client64
make
make install
5、之后编译自己的代码是出现的错误（类似的错误，也可以试试这个解决方法）
①/usr/bin/ld: warning: libclntsh.so.11.1, needed by /usr/local/lib/libocilib.so, not found (try using -rpath or -rpath-link)
/usr/local/lib/libocilib.so: undefined reference to `OCILobTrim2'

/usr/local/lib/libocilib.so: undefined reference to `OCIDescriptorAlloc'
/usr/local/lib/libocilib.so: undefined reference to `OCILobLoadFromFile2'
在/etc/ld.so.conf中添加 /home/oracle/cry/instantclient_11_2 后正常.（instantclient_11_2 这个文件就是上面的zip解压出来的）
②
./tests: error while loading shared libraries: xxx.so.0:cannot open shared object file: No such file or directory
出现这类错误表示，系统不知道
xxx.so
放在哪个目录下，这时候就要在/etc/
ld.so.conf中加入xxx.so所在的目录。
一般而言，有很多的so会存放在/usr/local/lib这个目录底下，去这个目录底下找，果然发现自己所需要的.so文件。
所以，在/etc/ld.so.conf中加入/usr/local/lib这一行，保存之后，再运行：/sbin/ldconfig –v更新一下配置即可。
以上整合修改自这四个地方，稍有修改，我无耻的加了原创，哈哈哈
