需要寫個指令碼，從sql檔案中提取uid，並拼成key，刪除redis中的這個key。
sql檔案形式：
update table_1 set column_1 = 9459885 where uid = 133333333
update table_1 set column_1 = 9459886 where uid = 133333334
redislist = ['127.0.0.1', '127.0.0.2']
for redishost in redislist:
print redishost
con = redis.redis(host=redishost, port=1111, db=0, password='password', decode_responses=true)
filename = "core_update_sql.txt"
lines = open(filename, "r").readlines()
flen = len(lines)
for i in range(flen):
begin = lines[i].rfind(' ') + 1
uid = lines[i][begin:]
key = "aaa_" + uid
print key
for con in conlist:
res = con.get(key)
print res
con.delete(key)
