如果需要redis持久化数据需要配置redis日志开启
在每次更新操作后进行日志记录，如果不开启，可能会在断电时导致一段时间内的数据丢失。
因为redis本身同步数据文件是按上面save条件来同步的，所以有的数据会在一段时间内只存在于内存中。
默认值为no
此时要在redis.conf中修改或者添加
appendonlyyes
更新日志文件名，默认值为appendonly.aof
#更新日志条件，共有3个可选值。
no表示等操作系统进行数据缓存同步到磁盘，always表示每次更新操作后手动调用fsync（）将数据写到磁盘，everysec表示每秒同步一次（默认值）。
#appendfsyncalways
appendfsynceverysec
