python批量连接mysql

注释:脚本(gomysql.py)需要进一步优化,初学者,努力中

首先配置需要执行的dbip.ini列表,格式如下

S1  192.168.0.5   3306  dbusername dbpasswd dbname
S2  192.168.0.6   3306 dbusername dbpasswd  dbname
S3  192.168.0.7   3306 dbusername dbpasswd  dbname

执行方法:./gomysql.py dbip.ini(参数一,数据库账号IP配置列表,实例如下) db.sql(参数二,执行的sql语句文本)

效果:

# ./readlnedb.py logdbip.ini 20150827/select_22.sql

logdbip.ini
20150827/select_22.sql
确认以上信息[y/n]:

脚本内容如下:

#!/usr/bin/python
#encoding:utf-8
import sys
import os
import MySQLdb
import datetime
if len(sys.argv) < 2:
 print "error: " + sys.argv[0] + "file1 file2"
 sys.exit()
file1=sys.argv[1]
file2=sys.argv[2]
print file1
print file2

#sql = open(file2,"r").read()
#print sql

str = raw_input("确认以上信息[y/n]:")
if str != "y":
   exit()

for line in open(file1,"r"):
   servername=line.strip().split()[0]
   ip=line.strip().split()[1]
   port=line.strip().split()[2]
   user=line.strip().split()[3]
   pswd=line.strip().split()[4]
   dbname=line.strip().split()[5]
   print "\n=======",servername,"==========="
   db = MySQLdb.connect(ip,user,pswd,dbname)
   cursor = db.cursor()
   for sql in open(file2,"r"):
    cursor.execute(sql)
    data = cursor.fetchall()
    for row in data:
           print "\n"
           num = 0
           while (num < len(row)):
             print row[num],
             num += 1
   db.close()
