VolatileLRU
按照LRU算法逐出原有数据，但仅逐出设置了过期时间的数据
VolatileTTL
仅逐出设置了过期时间的数据，并且是按照TTL有小到大的顺序进行逐出
AllKeysLRU
按照LRU算法逐出原有数据
VolatileRandom
随机逐出原有数据，但仅逐出设置了过期时间的数据
AllKeysRandom
随机逐出原有数据
NoEviction
不逐出任何数据，新数据的写入会得到一个错误信息
VolatileLFU
只从设置失效（expire set）的key中选择最不常用的key进行删除
AllkeysLFU
优先删除掉最不常用的key SourceByrd's Weblog-https://note.t4x.org/basic/centos-install-redis/
