本文档详细介绍了DB_MONITOR环境中cx_Oracle与MYSQLdb的安装步骤。首先，针对cx_Oracle，强调了设置ORACLE_HOME环境变量的重要性，并解决库文件复制与权限问题。接着，讲述了MySQLdb的安装过程，包括编辑mysql_config，执行build和install，以及处理因paramiko依赖pycrypto模块导致的报错。

1. 安装cx_oracle

下载：https://pypi.org/project/cx_Oracle/5.1.3/#files

[dbmon@mysql ~]$ tar -xvzf cx_Oracle-5.1.3.tar.gz

注意配置ORACLE_HOME,否则会报错

[root@mysql cx_Oracle-5.1.3]# python setup.py install
Traceback (most recent call last):
  File "setup.py", line 135, in <module>
    raise DistutilsSetupError("cannot locate an Oracle software " \
distutils.errors.DistutilsSetupError: cannot locate an Oracle software installation

还是报错：

[dbmon@mysql cx_Oracle-5.1.3]$ python setup.py install
running install
running build
running build_ext
building 'cx_Oracle' extension
gcc -pthread -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/home/dbmon/instantclient_11_2/sdk/include -I/usr/local/python-2.7.14/include/python2.7 -c cx_Oracle.c -o build/temp.linux-x86_64-2.7-11g/cx_Oracle.o -DBUILD_VERSION=5.1.3
In file included from /home/dbmon/instantclient_11_2/sdk/include/oci.h:3045,
                 from cx_Oracle.c:10:

/usr/bin/ld: cannot find -lclntsh
collect2: ld returned 1 exit status

将oracle_home中的libclntsh.so.11.1复制一份到libclntsh.so即可

[dbmon@mysql instantclient_11_2]$ cp libclntsh.so.11.1 libclntsh.so

又碰到权限问题

[dbmon@mysql cx_Oracle-5.1.3]$ python setup.py install
running install
