linux redis启动不来问题

1、Redis启动报错：Can't handle RDB format version 7 Fatal error loading the DB: Invalid argument. Exiting.

[root@shengyihuo01 backup]# journalctl -ex
解决: 删除 所有的dump.rdb文件 [rm -f /var/lib/redis/dump.rdb]，重新启动redis-server。

 

2、启动后exit[pessimism deny]

问题描述：

[root@shengyihuo01 backup]# journalctl -ex
pessimism deny ...
exit(0)

 

解决：
