Redis之-aof恢復

aof恢復簡講過程：

[root@ZFRC-YW-YJF-TEST-370123 redis]# pkill -9 redis
[root@ZFRC-YW-YJF-TEST-370123 ~]# cd /var/dir
[root@ZFRC-YW-YJF-TEST-370123 ~]# rm -rf *
清除掉現有環境備份文件；而後啓動服務器進程，添加新數據

[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-server ./redis.conf
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-server ./redis6380.conf
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-server ./redis6381.conf
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-cli
127.0.0.1:6379> keys *
(empty list or set)
127.0.0.1:6379> set site www.baidu.com
OK
127.0.0.1:6379> set name yjf
OK
127.0.0.1:6379> set addr bj
OK
127.0.0.1:6379> flushall
OK
127.0.0.1:6379> get name
(nil)

此時必定要先中止服務，避免其餘人有寫入操做，重寫aof。何況aof記錄着也有flushall操做。
[root@ZFRC-YW-YJF-TEST-370123 dir]# more laoyang-appendonly.aof

$8
flushall

127.0.0.1:6379> shutdown nosave ---shutdown 操做不記錄日誌
not connected>

而後編輯一下aof生成文件。將最後危險操做flushall給dd掉。--注意記錄的格式，通常是*開始，命令結尾；

[root@ZFRC-YW-YJF-TEST-370123 dir]# vim laoyang-appendonly.aof
刪除下面三行，保存退出
*1
$8
flushall

而後重啓一下服務，登錄查詢，若是麼有，退出後，再次登錄查詢
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-server ./redis.conf
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-cli
127.0.0.1:6379> get name
(nil)
127.0.0.1:6379> exit
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-cli
127.0.0.1:6379> get name
yjf

檢查rdb文件
[root@ZFRC-YW-YJF-TEST-370123 redis]# ./bin/redis-check-rdb /var/dir/dump6380.rdb
