摘要：連接當(dāng)前環(huán)境下載安裝包由于我本地版本是所以選擇是版本參考安裝包列表安裝安裝查看當(dāng)前引入模塊庫(kù)的路徑檢查安裝路徑，如果文件不在以上引入路徑內(nèi)需要將該文件拷貝到以上引入路徑所以我這里不需要進(jìn)行拷貝操作

當(dāng)前環(huán)境：Linux Centos 7

由于我本地Python版本是2.7,所以選擇是2.7版本

wget https://pypi.python.org/packages/e1/18/00987c6a9af9568ee87d1fcba877407684a3f1b87515e5eb82d5d5acb9ff/cx_Oracle-6.0rc1-py27-1.x86_64.rpm#md5=ff8f5cce07bd5ec8ed3ce5c79d451474

參考:

python-cx_Oracle
安裝包列表

安裝：

rpm -ivh cx_Oracle-6.0rc1-py27-1.x86_64.rpm

查看當(dāng)前python引入模塊庫(kù)的路徑

檢查安裝路徑，如果cx_Oracle.so文件不在以上python引入路徑內(nèi)需要將該文件拷貝到以上python引入路徑,所以我這里不需要進(jìn)行拷貝操作

[root ~]# rpm -qa | grep cx_Oracle | xargs rpm -ql

由于Oracle官網(wǎng)下載東西存在Auth認(rèn)證，所以簡(jiǎn)單點(diǎn)就點(diǎn)擊選中的rpm包保存在windows上，然后上傳到linux上即可
注意：

下載的版本要和連接的Oracle基本一致，我需要連接的Oracle版本是11.2，所以我下載的是oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm


操作系統(tǒng)要和之前下載的cx_Oracle要一致，這很重要?。?！我在這個(gè)上面栽了跟頭，花了比較多的時(shí)間。。。所以我需要下載64位的
在Oracle官網(wǎng)下載東西你得先勾選Accept License Agreement，否則你下載不了
其次你得有Oracle的賬號(hào)

rpm -ivh oracle-instantclient11.2-basic-11.2.0.3.0-1.x86_64.rpm

修改Oracle安裝路徑
將client64改為client，至于為什么要改暫時(shí)還不清楚，只知道不改的話會(huì)報(bào)錯(cuò)Oracle Client library cannot be loaded: libclntsh.so: cannot open shared object file: No such file or directory

cd /usr/lib/oracle/11.2/
mv client64 client

打開(kāi)~/.bashrc,追加環(huán)境變量路徑

vim ~/.bashrc

配置環(huán)境變量
