一、什么是持久化
基础名词解释：https://www.cnblogs.com/chenliangcl/p/7240350.html
此处我是使用的AOF来做的持久化
bind 127.0.0.1 port 36379 tcp-backlog 511 timeout 0 tcp-keepalive 0 daemonize no pidfile /var/run/redis36379.pid loglevel notice logfile "/mnt/logs/redis/redis36379.log" databases 16 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump36379.rdb dir /mnt/data/redis36379/ slave-serve-stale-data yes slave-read-only yes repl-disable-tcp-nodelay no slave-priority 100 #追加式持久化配置.每当Redis接受到会修改数据集的命令时,就会把命令追加到AOF文件里. appendonly yes appendfilename "appendonly36379.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit slave 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 aof-rewrite-incremental-fsync yes rename-command FLUSHALL "" rename-command CONFIG "" rename-command EVAL ""
测试：设置一个值，然后重启redis之后，测试，是否存在，存在说明持久化ok
