代码如下:
import os
import sys
import MySQLdb
def getStatus(conn):
    query = " SHOW SLAVE STATUS "

    # print query
    cursor = conn.cursor()
    cursor.execute(query)
    result = cursor.fetchall()
    return result[0]
def resolve(conn):
    cursor = conn.cursor()
    query1 = "set global sql_slave_skip_counter=1"
    query2 = "START SLAVE"
    query3 = "SHOW SLAVE STATUS"

    cursor.execute(query1)
    cursor.execute(query2)
    cursor.execute(query3)
    conn.commit()

if __name__ == '__main__':
    conn = MySQLdb.connect(read_default_file="~/.my.cnf", db="", port=3306, charset="utf8")
    status = getStatus(conn)
    print "Master_Log_File: %s" % status[5]
    print "Read_Master_Log_Pos: %s" % status[6]
    print "Seconds_Behind_Master: %s" % status[-1]
    if status[32] is None:
        resolve(conn)
    else:
        print 'resolved'
