MySQL数据库连接重试功能和连接超时功能的DB连接Python实现

def reConndb(self):
# 数据库连接重试功能和连接超时功能的DB连接
_conn_status = True
_max_retries_count = 10 # 设置最大重试次数
_conn_retries_count = 0 # 初始重试次数
_conn_timeout = 3 # 连接超时时间为3秒
while _conn_status and _conn_retries_count <= _max_retries_count:
try:
print '连接数据库中..'
conn = pymysql.connect(host=DB_HOST, port=3306, user=DB_USER, passwd=DB_PASSWORD, db=DB_DATABASE, charset=DB_CHARSET, connect_timeout=_conn_timeout)
_conn_status = False # 如果conn成功则_status为设置为False则退出循环,返回db连接对象
return conn
except:
_conn_retries_count += 1
print _conn_retries_count
print 'connect db is error!!'
time.sleep(3) # 此为测试看效果
continue
