(empty array)
127.0.0.1:6379> multi
OK
127.0.0.1:6379(TX)> set a1 v1
QUEUED
127.0.0.1:6379(TX)> set a2 v2
QUEUED
127.0.0.1:6379(TX)> set a3 v3
QUEUED
127.0.0.1:6379(TX)> exec

3) OK
127.0.0.1:6379> keys *
1) "a2"
2) "a1"

2、Redis事务错误处理

2) "a1"
3) "a3"
127.0.0.1:6379> multi
OK
127.0.0.1:6379(TX)> set a4 v4
QUEUED
