RedLock分布式鎖

RedLock 是一個(gè)使用 Python 和 Redis 實(shí)現(xiàn)的分布式鎖。實(shí)現(xiàn)了來(lái)自 @antirez 的 RedLock 算法。

示例代碼：

from redlock import RedLock
# By default, if no redis connection details are 
# provided, RedLock uses redis://127.0.0.1:6379/0
lock =  RedLock("distributed_lock")
lock.acquire()
do_something()
lock.release()

from redlock import RedLock
with RedLock("distributed_lock"):
    do_something()

from redlock import RedLock
with RedLock("distributed_lock", 
              connection_details=[
                {host='xxx.xxx.xxx.xxx', port=6379, db=0},
                {host='xxx.xxx.xxx.xxx', port=6379, db=0},
                {host='xxx.xxx.xxx.xxx', port=6379, db=0},
                {host='xxx.xxx.xxx.xxx', port=6379, db=0},
              ]
            ):
    do_something()
