说明：
很久没弄邮箱了，老早就有想法写个脚本自动生成全局地址本，每次添加一个用户还要SSH连到服务器加个地址本，麻烦死了，想必大家都有这样的情况；这周有点空就研究了下python语言，写了这么个脚本出来，共享出来一起学习。
1、安装
一般情况下系统已默认安装，我的操作系统centos6.5装的是python2.4.3
yum install -y MySQL-python
2、脚本
cd /var/www/excuite/extmail vi globabook.py
#!/usr/bin/python
#coding=utf-8
#save in /var/www/excuite/extmail
#yum install -y MySQL-python
#apt-get install python-MySQLdb
import MySQLdb
def SqlResult(sqlcmd):
try:
conn = MySQLdb.connect(host='localhost',user='root',passwd='password',db='extmail',port=3306) # 定义连接，修改登陆账号成你自己的
cur = conn.cursor()
cur.execute(sqlcmd)
result = cur.fetchall()
cur.close()
conn.close()
return result
except MySQLdb.Error,e:
print 'mysql error msg:',e
def Books():
d = {}
domains = 'select domain from domain;'
for domain in SqlResult(domains):
root = domain[0].split('.')[0]
if root == 'defaultdomain': #defaltdomain改成你的默认域名
f = 'globabook.cf'
else:
f = 'globabook-'+root+'.cf'
d[domain[0]] = f
return d
def Users(domain):
us = ["Name,Mail,Company,Phone"]
usernames = "select name,username from mailbox where active='1' and domain='%s';" % domain
for user in SqlResult(usernames):
u='\n"'+user[0].decode("utf-8")+'","'+user[1]+'"'
us.append(u)
return us
def Main():
bs = Books()
for dm in bs:
f = bs.get(dm)
book = open(f,"w")
us = Users(dm)
for user in us:
book.write(user.encode("utf-8"))
book.close()
print "Congratulations, the %s is update!" % f
print "ALL Globabook Files Are Updated !"
Main()3、执行脚本
chmod +x globabook.py python globabook.py
4、添加任务，每日刷新
crontab -e 0 0 * * * cd /var/www/extsuite/extmail && /usr/bin/python globabook.py
5、脚本讲解
SqlResult函数用来获取数据库数据；Books函数返回一个字典，键是域名，值是域名对应的地址本文件名称；Users函数用来获取数据库中用户数据，只取"名字"和"邮箱地址"；主函数Main调用以上函数，将用户数据按域名存入相应的地址本文件；每天执行时会清空地址本重新写入数据。
