堡垒机执行流程:
注:配置.brashrc实现ssh登陆后自动执行脚本,如:/usr/bin/python /home/wupeiqi/menu.py
实现过程
步骤一,实现用户登陆
1 2 3 4 5 6 7 8 |
import getpass
user = raw_input ( ‘username:‘ )
pwd = getpass.getpass( ‘password‘ )
if user = = ‘alex‘ and pwd = = ‘123‘ :
print ‘登陆成功‘
else :
print ‘登陆失败‘
|
步骤二,根据用户获取相关服务器列表
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
dic = {
‘alex‘ : [
‘172.16.103.189‘ ,
‘c10.puppet.com‘ ,
‘c11.puppet.com‘ ,
],
‘eric‘ : [
‘c100.puppet.com‘ ,
]
}
host_list = dic[ ‘alex‘ ]
print ‘please select:‘
for index, item in enumerate (host_list, 1 ):
print index, item
inp = raw_input ( ‘your select (No):‘ )
inp = int (inp)
hostname = host_list[inp - 1 ]
port = 22
|
步骤三,根据用户名、私钥登陆服务器
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
tran = paramiko.Transport((hostname, port,))
tran.start_client()
default_path = os.path.join(os.environ[ ‘HOME‘ ], ‘.ssh‘ , ‘id_rsa‘ )
key = paramiko.RSAKey.from_private_key_file(default_path)
tran.auth_publickey( ‘wupeiqi‘ , key)
# 打开一个通道
chan = tran.open_session()
# 获取一个终端
chan.get_pty()
# 激活器
chan.invoke_shell()
#########
# 利用sys.stdin,肆意妄为执行操作
# 用户在终端输入内容,并将内容发送至远程服务器
# 远程服务器执行命令,并将结果返回
# 用户终端显示内容
#########
chan.close()
tran.close()

注:密码验证 t.auth_password(username, pw)

Python 操作 Mysql 模块的安装
1 2 3 4 5 |
linux:
yum install MySQL - python
window:
http: / / files.cnblogs.com / files / wupeiqi / py - mysql - win. zip
|
SQL基本使用
1、数据库操作
1 2 3 |
show databases;
use [databasename];
create database [name];
|
2、数据表操作
1 2 3 4 5 6 7 8 9 10 |
show tables;
create table students
(
id int not null auto_increment primary key,
name char( 8 ) not null,
sex char( 4 ) not null,
age tinyint unsigned not null,
tel char( 13 ) null default "-"
);
|
3、数据操作
1 2 3 4 5 6 7 |
insert into students(name,sex,age,tel) values( ‘alex‘ , ‘man‘ , 18 , ‘151515151‘ )
delete from students where id = 2 ;
update students set name = ‘sb‘ where id = 1 ;
select * from students
|
4、其他

主键
外键

Python MySQL API
一、插入数据
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
import MySQLdb
conn = MySQLdb.connect(host = ‘127.0.0.1‘ ,user = ‘root‘ ,passwd = ‘1234‘ ,db = ‘mydb‘ )
cur = conn.cursor()
reCount = cur.execute( ‘insert into UserInfo(Name,Address) values(%s,%s)‘ ,( ‘alex‘ , ‘usa‘ ))
# reCount = cur.execute(‘insert into UserInfo(Name,Address) values(%(id)s, %(name)s)‘,{‘id‘:12345,‘name‘:‘wupeiqi‘})
conn.commit()
cur.close()
conn.close()
print reCount
|
注意:cur.lastrowid
二、删除数据
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
import MySQLdb
conn = MySQLdb.connect(host = ‘127.0.0.1‘ ,user = ‘root‘ ,passwd = ‘1234‘ ,db = ‘mydb‘ )
cur = conn.cursor()
reCount = cur.execute( ‘delete from UserInfo‘ )
conn.commit()
cur.close()
conn.close()
print reCount
|
三、修改数据
1 2 3 4 5 6 7 8 9 10 11 12 13 |
import MySQLdb
conn = MySQLdb.connect(host = ‘127.0.0.1‘ ,user = ‘root‘ ,passwd = ‘1234‘ ,db = ‘mydb‘ )
cur = conn.cursor()
reCount = cur.execute( ‘update UserInfo set Name = %s‘ ,( ‘alin‘ ,))
conn.commit()
cur.close()
conn.close()
print reCount
|
四、查数据
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |

import MySQLdb

print cur.fetchone()
print cur.fetchone()
cur.scroll( - 1 ,mode = ‘relative‘ )
print cur.fetchone()
print cur.fetchone()
cur.scroll( 0 ,mode = ‘absolute‘ )
print cur.fetchone()

cur = conn.cursor()
reCount = cur.execute( ‘select Name,Address from UserInfo‘ )
nRet = cur.fetchall()
cur.close()
conn.close()
print reCount
print nRet
for i in nRet:
print i[ 0 ],i[ 1 ]
