redis服务启动不了的解决办法（服务器应非法关机了）

Posted 2020-12-28

1、确认redis没运行。

[[email protected] run]# /etc/init.d/kkmail_redis status
redis is not running

2、删除pid文件（从配置文件里面获取pid文件路径），然后重启还是不行。

-rw-r--r-- 1 root root 5 8月   6 14:37 redis.pid

3、查看错误日志。

[[email protected] run]# cd /usr/local/kk-mail/log/redis/
[[email protected] redis]# tail -n 20 redis.log
           _.-``__ ''-._

[4807] 06 Aug 14:37:52.782 # Fatal error loading the DB: Invalid argument. Exiting.

4、删除rdb文件，然后重启redis服务      

[[email protected] redis]# rm -f /usr/local/kk-mail/data/redis/data/dump.rdb
[[email protected] redis]# /etc/init.d/kkmail_redis restart
Stopping redis ...
Could not connect to Redis at 127.0.0.1:6379: Connection refused
Redis is stopped
Starting Redis server...

5、去人redis已经可以成功启动了

[[email protected] redis]# /etc/init.d/kkmail_redis status
redis ( pid 5219 ) is running
