问题原因：master和slave建立连接，第一次evalsha会转成eval携带script信息，但是如果是从slave上拉取，那么slave本身没办法把evalsha转换eval，所以就有了这个问题。这个本身在redis级联场景也会遇到这个问题，lua脚本如果不存在需要客户端的处理逻辑介入重新load。
解决方式：
- 要么从master上拉取，
- 要么自己把lua脚本同步到目的端,
- 或者统一都启用redis.replicate_commands()转成事务。

对于redis自身级联场景，如果是4.0.4之前是有这个问题，但是4.0.4之后由于rdb中携带lua脚本信息，所以没有这个问题。
总结一下：这个问题是redis自身机制造成的，而不是redis-shake。
