reids持久化异常：MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persis

出现这个异常时redis就行持久化保存时出现了异常，我的机器是centos，redis是装载为了服务

输入redis-cli进入redis控制菜单

redis-cli

获取日志文件地址：

127.0.0.1:6379> config get logfile
1) "logfile"
2) "/home/logs/myredis/redis_log.log"

可知，我机器的日志文件在/home/logs/myredis/redis_log.log中，用vim打开看看

 vim /home/logs/myredis/redis_log.log

跳转至最后一行，发现是/etc/cron.d这个文件无权限

23343:C 14 Jun 17:30:19.055 # Failed opening the RDB file web (in server root dir /etc/cron.d) for saving: Permission denied

使用chmod命令修改其权限，没想到被拒绝了

[root@VM-8-10-centos etc]# chmod 777 cron.d
chmod: changing permissions of ‘cron.d’: Operation not permitted

使用chattr更改其属性,然后更改：

[root@VM-8-10-centos etc]# chattr -ia cron.d
[root@VM-8-10-centos etc]# chmod 777 cron.d

成功！
