1.pymsql的使用python

2.SQLAchemy使用mysql

3.Paramikoios

4.經過ORM功能使用和Paramiko的使用實現一個簡單的堡壘機模型。sql

一.pymsql的使用

pymsql是Python中操做MySQL的模塊，其使用方法和MySQLdb幾乎相同。shell

下載安裝：數據庫

pip3 install pymysql

使用編程

一、執行SQLjson

# -*- coding:utf-8 -*-
import pymysql
 
# 建立鏈接
conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='123', db='t1')
# 建立遊標
cursor = conn.cursor()
 
# 執行SQL，並返回收影響行數
effect_row = cursor.execute("update hosts set host = '1.1.1.2'")
 
# 執行SQL，並返回受影響行數
#effect_row = cursor.execute("update hosts set host = '1.1.1.2' where nid > %s", (1,))
 
# 執行SQL，並返回受影響行數
#effect_row = cursor.executemany("insert into hosts(host,color_id)values(%s,%s)", [("1.1.1.11",1),("1.1.1.11",2)])
 
 
# 提交，否則沒法保存新建或者修改的數據
conn.commit()
 
# 關閉遊標
cursor.close()
# 關閉鏈接
conn.close()

二、獲取新建立數據自增IDwindows

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import pymysql
 
conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='123', db='t1')
cursor = conn.cursor()
cursor.executemany("insert into hosts(host,color_id)values(%s,%s)", [("1.1.1.11",1),("1.1.1.11",2)])
conn.commit()
cursor.close()
conn.close()
 
# 獲取最新自增ID
new_id = cursor.lastrowid

三、獲取查詢數據

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import pymysql
 
conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='123', db='t1')
cursor = conn.cursor()
cursor.execute("select * from hosts")
 
# 獲取第一行數據
row_1 = cursor.fetchone()
 
# 獲取前n行數據
# row_2 = cursor.fetchmany(3)
# 獲取全部數據
# row_3 = cursor.fetchall()
 
conn.commit()
cursor.close()
conn.close()

注：在fetch數據時按照順序進行，可使用cursor.scroll(num,mode)來移動遊標位置，如：

cursor.scroll(1,mode='relative') # 相對當前位置移動
cursor.scroll(2,mode='absolute') # 相對絕對位置移動

四、fetch數據類型

　　關於默認獲取的數據是元祖類型，若是想要或者字典類型的數據，即：

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import pymysql
 
conn = pymysql.connect(host='127.0.0.1', port=3306, user='root', passwd='123', db='t1')
 
# 遊標設置爲字典類型
cursor = conn.cursor(cursor=pymysql.cursors.DictCursor)
r = cursor.execute("call p1()")
 
result = cursor.fetchone()
 
conn.commit()
cursor.close()
conn.close()
SQLAchemy

二.SQLAchemy

SQLAlchemy是Python編程語言下的一款ORM框架，該框架創建在數據庫API之上，使用關係對象映射進行數據庫操做，簡言之即是：將對象轉換成SQL，而後使用數據API執行SQL並獲取執行結果。

SQLAlchemy自己沒法操做數據庫，其必須以來pymsql等第三方插件，Dialect用於和數據API進行交流，根據配置文件的不一樣調用不一樣的數據庫API，從而實現對數據庫的操做，如：

MySQL-Python
    mysql+mysqldb://<user>:<password>@<host>[:<port>]/<dbname>
  
pymysql
    mysql+pymysql://<username>:<password>@<host>/<dbname>[?<options>]
  
MySQL-Connector
    mysql+mysqlconnector://<user>:<password>@<host>[:<port>]/<dbname>
  
cx_Oracle
    oracle+cx_oracle://user:pass@host:port/dbname[?key=value&key=value...]
  
更多詳見：http://docs.sqlalchemy.org/en/latest/dialects/index.html

底層處理

使用 Engine/ConnectionPooling/Dialect 進行數據庫操做，Engine使用ConnectionPooling鏈接數據庫，而後再經過Dialect執行SQL語句。

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from sqlalchemy import create_engine
 
 
engine = create_engine("mysql+pymysql://root:123@127.0.0.1:3306/t1", max_overflow=5)
 
# 執行SQL
# cur = engine.execute(
#     "INSERT INTO hosts (host, color_id) VALUES ('1.1.1.22', 3)"
# )
 
# 新插入行自增ID
# cur.lastrowid
 
# 執行SQL
# cur = engine.execute(
#     "INSERT INTO hosts (host, color_id) VALUES(%s, %s)",[('1.1.1.22', 3),('1.1.1.221', 3),]
# )
 
 
# 執行SQL
# cur = engine.execute(
#     "INSERT INTO hosts (host, color_id) VALUES (%(host)s, %(color_id)s)",
#     host='1.1.1.99', color_id=3
# )
 
# 執行SQL
# cur = engine.execute('select * from hosts')
# 獲取第一行數據
# cur.fetchone()
# 獲取第n行數據
# cur.fetchmany(3)
# 獲取全部數據
# cur.fetchall()

ORM功能使用

使用 ORM/Schema Type/SQL Expression Language/Engine/ConnectionPooling/Dialect 全部組件對數據進行操做。根據類建立對象，對象轉換成SQL，執行SQL。

一、建立表

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String, ForeignKey, UniqueConstraint, Index
from sqlalchemy.orm import sessionmaker, relationship
from sqlalchemy import create_engine

engine = create_engine("mysql+pymysql://root:123@127.0.0.1:3306/t1", max_overflow=5)

Base = declarative_base()

# 建立單表
class Users(Base):
    __tablename__ = 'users'
    id = Column(Integer, primary_key=True)
    name = Column(String(32))
    extra = Column(String(16))

    __table_args__ = (
    UniqueConstraint('id', 'name', name='uix_id_name'),
        Index('ix_id_name', 'name', 'extra'),
    )


# 一對多
class Favor(Base):
    __tablename__ = 'favor'
    nid = Column(Integer, primary_key=True)
    caption = Column(String(50), default='red', unique=True)


class Person(Base):
    __tablename__ = 'person'
    nid = Column(Integer, primary_key=True)
    name = Column(String(32), index=True, nullable=True)
    favor_id = Column(Integer, ForeignKey("favor.nid"))


# 多對多
class Group(Base):
    __tablename__ = 'group'
    id = Column(Integer, primary_key=True)
    name = Column(String(64), unique=True, nullable=False)
    port = Column(Integer, default=22)


class Server(Base):
    __tablename__ = 'server'

    id = Column(Integer, primary_key=True, autoincrement=True)
    hostname = Column(String(64), unique=True, nullable=False)


class ServerToGroup(Base):
    __tablename__ = 'servertogroup'
    nid = Column(Integer, primary_key=True, autoincrement=True)
    server_id = Column(Integer, ForeignKey('server.id'))
    group_id = Column(Integer, ForeignKey('group.id'))


def init_db():
    Base.metadata.create_all(engine)


def drop_db():
    Base.metadata.drop_all(engine)

ForeignKeyConstraint(['other_id'], ['othertable.other_id']),

二、操做表

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Column, Integer, String, ForeignKey, UniqueConstraint, Index
from sqlalchemy.orm import sessionmaker, relationship

Base = declarative_base()

# 建立單表
class Users(Base):
    __tablename__ = 'users'
    id = Column(Integer, primary_key=True)
    name = Column(String(32))
    extra = Column(String(16))

    __table_args__ = (
    UniqueConstraint('id', 'name', name='uix_id_name'),
        Index('ix_id_name', 'name', 'extra'),
    )

    def __repr__(self):
        return "%s-%s" %(self.id, self.name)

# 一對多
class Favor(Base):
    __tablename__ = 'favor'
    nid = Column(Integer, primary_key=True)
    caption = Column(String(50), default='red', unique=True)

    def __repr__(self):

class Person(Base):
    __tablename__ = 'person'
    nid = Column(Integer, primary_key=True)
    name = Column(String(32), index=True, nullable=True)
    favor_id = Column(Integer, ForeignKey("favor.nid"))
    # 與生成表結構無關，僅用於查詢方便
    favor = relationship("Favor", backref='pers')

# 多對多
class ServerToGroup(Base):
    __tablename__ = 'servertogroup'
    nid = Column(Integer, primary_key=True, autoincrement=True)
    server_id = Column(Integer, ForeignKey('server.id'))
    group_id = Column(Integer, ForeignKey('group.id'))
    group = relationship("Group", backref='s2g')
    server = relationship("Server", backref='s2g')

class Group(Base):
    __tablename__ = 'group'
    id = Column(Integer, primary_key=True)
    name = Column(String(64), unique=True, nullable=False)
    port = Column(Integer, default=22)
    # group = relationship('Group',secondary=ServerToGroup,backref='host_list')

def init_db():
    Base.metadata.create_all(engine)


def drop_db():
    Base.metadata.drop_all(engine)


Session = sessionmaker(bind=engine)

表結構+鏈接數據庫

操做表

session.add(obj)
session.add_all([
    Users(name="alex1", extra='sb'),
    Users(name="alex2", extra='sb'),

表結構操做聯繫

三.Paramiko

paramiko模塊，基於SSH用於鏈接遠程服務器並執行相關操做。

一、安裝

pip3 install paramiko

二、使用

SSHClient

用於鏈接遠程服務器並執行基本命令

基於用戶名密碼鏈接：

import paramiko
   
# 建立SSH對象
ssh = paramiko.SSHClient()
# 容許鏈接不在know_hosts文件中的主機
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 鏈接服務器
ssh.connect(hostname='c1.centos1.com', port=22, username='zhaowencheng', password='123456')
   
# 執行命令
stdin, stdout, stderr = ssh.exec_command('ls')
# 獲取命令結果
result = stdout.read()
   
# 關閉鏈接
ssh.close()

import paramiko

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='zhaowencheng', password='123456')

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')
print stdout.read()

transport.close()

SSHClient 封裝 Transport

基於公鑰密鑰鏈接：

import paramiko
  
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
  
# 建立SSH對象
ssh = paramiko.SSHClient()
# 容許鏈接不在know_hosts文件中的主機
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 鏈接服務器
ssh.connect(hostname='c1.centos.com', port=22, username='zhaowencheng', key=private_key)
  
# 執行命令
stdin, stdout, stderr = ssh.exec_command('ls')
# 獲取命令結果
result = stdout.read()
  
# 關閉鏈接
ssh.close()

基於公鑰密鑰鏈接：

import paramiko
  
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
  
# 建立SSH對象
ssh = paramiko.SSHClient()
# 容許鏈接不在know_hosts文件中的主機
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 鏈接服務器
ssh.connect(hostname='c1.centos.com', port=22, username='zhaowencheng', key=private_key)
  
# 執行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 獲取命令結果
result = stdout.read()
  
# 關閉鏈接
ssh.close()

import paramiko

private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')

transport = paramiko.Transport(('hostname', 22))
transport.connect(username='zhaowencheng', pkey=private_key)

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df')

transport.close()

SSHClient 封裝 Transport

SFTPClient

用於鏈接遠程服務器並執行上傳下載

基於用戶名密碼上傳下載：

import paramiko
  
transport = paramiko.Transport(('hostname',22))
transport.connect(username='wupeiqi',password='123')
  
sftp = paramiko.SFTPClient.from_transport(transport)
# 將location.py 上傳至服務器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
# 將remove_path 下載到本地 local_path
sftp.get('remove_path', 'local_path')
  
transport.close()

基於公鑰密鑰上傳下載：

import paramiko
  
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
  
transport = paramiko.Transport(('hostname', 22))
transport.connect(username='zhaowencheng', pkey=private_key )
  
sftp = paramiko.SFTPClient.from_transport(transport)
# 將location.py 上傳至服務器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
# 將remove_path 下載到本地 local_path
sftp.get('remove_path', 'local_path')
  
transport.close()

四.堡壘機

堡壘機執行流程：

管理員爲用戶在服務器上建立帳號（將公鑰放置服務器，或者使用用戶名密碼）
用戶登錄堡壘機，輸入堡壘機用戶名密碼，現實當前用戶管理的服務器列表
用戶選擇服務器，並自動登錄
執行操做並同時將用戶操做記錄

實現過程:

1.基礎：

import paramiko
import sys
import os
import socket
import select
import getpass
 
tran = paramiko.Transport(('10.211.55.4', 22,))
tran.start_client()
tran.auth_password('wupeiqi', '123')
 
# 打開一個通道
chan = tran.open_session()
# 獲取一個終端
chan.get_pty()
# 激活器
chan.invoke_shell()
 
#########
# 利用sys.stdin,肆意妄爲執行操做
# 用戶在終端輸入內容，並將內容發送至遠程服務器
# 遠程服務器執行命令，並將結果返回
# 用戶終端顯示內容
#########
 
chan.close()
tran.close()
