MySQL服務器已經消失 - Python

我每天都會收到以下消息。我的腳本正在運行cron作業。誰能幫助解決這個問題嗎？MySQL服務器已經消失 - Python

File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute 
    self.errorhandler(self, exc, value) 
    File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler 
    raise errorclass, errorvalue 
_mysql_exceptions.OperationalError: (2006, 'MySQL server has gone away')

我的代碼：

def get_id(test_mysql_conn,id): 
    cursor = test_mysql_conn.cursor() 
    cursor.execute("""select id from test where id = %s """, (id)) 
    row = cursor.fetchone() 
    if row is not None: 
     return row[0] 
    return 0

嘗試follwing

if (os.getenv('SERVER_SOFTWARE') and os.getenv('SERVER_SOFTWARE').startswith('Google App Engine/')): 
      db = MySQLdb.connect(unix_socket = UNIX_SOCKET + INSTANCE_NAME, host =" HOST/IP", db = "DB_Name", user = "User_Name") //if your mysql is on google server 
     else: 
      db = MySQLdb.connect(host = "HOST/IP", port = "Port_number", db = "DB_name", user = "User_Name", passwd = "password") 

    cursor = db.cursor() 
    cursor.connection.autocommit(True) 

except Exception, err: 
    logging.info("Error In DataBase Connection : " + traceback.format_exc()) 
    return 'DataBaseProblem'   
try: 
    sql = query+str(req_args) 
    logging.info("QUERY = "+str(sql)) 
    cursor.execute(sql) 
    procedureResult = cursor.fetchall(); 
    if str(procedureResult) == '()': 
     logging.info("Procedure Returned 0 Record") 
     procedureResult = 'DataBaseProblem' 


    #logging.info("procedureResult : " + str(procedureResult)) 
except Exception, err: 
    #trackBack = str (traceback.format_exc()) 
    #raise Exception('DataBaseProblem',trackBack) 
    procedureResult="DataBaseProblem"

爲MySQL端口號3306

當你打開一個MySQL連接，但不關閉此情況它。 MySQL的事物有一個超時。

你可以做的一件事就是在完成使用時關閉連接。另一個將使用一個支持此或內置的ORM（SQLAlchemy是我相信）
