Python切换到新master的脚本

今天看书上有个不错的切换master的脚本，python编写的；可以自动切换到新master上的脚本，拿下来分享下；

[html]
def  replicate_to_position(server,pos): 
server.sql("START SLAVE UNTIL MASTER_LOT_FILE=%s,MASTER_LOG_POS=%s",(pos.file,po 
s.pos)) 
server.sql("SELECT MASTER_POS_WAIT(%s,%s)",(pos.file,pos.pos)) 
  
def  switch_to_master(server,standby) 
       stop_slave(server) 
       stop_slave(standby) 
       server_pos = fetch_slave_position(server) 
       standby_pos = fetch_slave_position(standby) 
       if   server_pos < standby_pos: 
           replicate_to_position(server,standby_pos) 
       elif server_pos  > standby_pos: 
           replicate_to_position(standby,server_pos) 
       master_pos = fetch_master_positino(standby) 
       change_master(server,standby,master_pos) 
       start_slave(standby) 
       start_slave(server) 

def  replicate_to_position(server,pos):
server.sql("START SLAVE UNTIL MASTER_LOT_FILE=%s,MASTER_LOG_POS=%s",(pos.file,po
s.pos))
server.sql("SELECT MASTER_POS_WAIT(%s,%s)",(pos.file,pos.pos))
 
def  switch_to_master(server,standby)
       stop_slave(server)
       stop_slave(standby)
       server_pos = fetch_slave_position(server)
       standby_pos = fetch_slave_position(standby)
       if   server_pos < standby_pos:
           replicate_to_position(server,standby_pos)
       elif server_pos  > standby_pos:
           replicate_to_position(standby,server_pos)
       master_pos = fetch_master_positino(standby)
       change_master(server,standby,master_pos)
       start_slave(standby)
       start_slave(server)
