centos 6.5 安装 cx_Oracle 5.12 步骤 ，使用oracle instantclient12.1

新建sh文件

内容如下：

以su用户执行这个文件

#!/bin/bash

# NOTE: Oracle requires at least 1176 MB of swap (or something around there).
# If you are using CentOS in a VMWare VM, there's a good chance that you don't have enough by default.
# If this describes you and you need to add more swap, see the
# "Adding a Swap File to a CentOS System" section, here:
# http://www.techotopia.com/index.php/Adding_and_Managing_CentOS_Swap_Space

# Install basic dependencies
sudo yum -y install libaio bc flex

echo "Now go get some the following two RPMs ..."
echo "- basic: oracle-instantclient12.1-basic-12.1.0.1.0-1.x86_64.rpm"
echo "- SDK/devel: oracle-instantclient12.1-devel-12.1.0.1.0-1.x86_64"
echo "... from this URL: http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html"
echo "WARNING: It's pretty annoying, they make you sign up for an Oracle account, etc."
echo 'I will assume you have put these two files are into the same folder'
echo "Press any key once you're ready" && read -n 1 -s

sudo rpm -ivh oracle-instantclient12.1-basic-*
sudo rpm -ivh oracle-instantclient12.1-devel-*

# (SIDENOTE: I had to alter it by doing some digging around for where the Oracle RPMs really installed to;
# if you ever need to do this, do a command like this:
#     rpm -qlp <rpm_file_of_concern.rpm>)

# INSTALL cx_Oracle #
#####################

pip install cx_Oracle

　　

 

 

 

 

 

 

如果执行出错，那么请下载cx_Oracle 5.12的源码进行编译

下载地址http://cx-oracle.sourceforge.net/

请对应python版本、OS版本

#python3 setup.py build install 

请修改setup.py中的

filesToCheck = [

                ("11g", "libclntsh.so.12.1"),

                ("10g", "libclntsh.so.10.1"),

                ("9i", "libclntsh.so.9.0")

因为我们安装的instantclient12.1是12.1版本，所以安装前检查文件的路径应该是libclntsh.so.12.1。

 

然后在python3中import cx_Oracle

不报错说明安装成功。

 

---更新

如果出现ImportError: libclntsh.so.11.1: cannot open shared object file: No such file or directory

说明路径不对，没有加载上

执行# find / -name libclntsh.so.*获得实际的路径是

/usr/lib/oracle/12.1/client64/lib/libclntsh.so.12.1

那么要把这个路径加载上

编辑/etc/ld.so.conf

gedit /etc/ld.so.conf

在最后一行输入获取的路径

/usr/lib/oracle/12.1/client64/lib/

别忘了最后#ldconfig一下
