redis快照关闭导致不能持久化的问题

1，redis logs信息
tail -f logs/access.log
18517:C 01 Jul 11:16:56.094 # Failed opening the RDB file root (in server root dir /etc/cron.d) for saving: Permission denied
31521:M 01 Jul 11:16:56.181 # Background saving error
31521:M 01 Jul 11:17:02.071 * 1 changes in 900 seconds. Saving...
31521:M 01 Jul 11:17:02.071 * Background saving started by pid 18530
18530:C 01 Jul 11:17:02.078 # Failed opening the RDB file root (in server root dir /etc/cron.d) for saving: Permission denied
31521:M 01 Jul 11:17:02.173 # Background saving error
31521:M 01 Jul 11:17:08.066 * 1 changes in 900 seconds. Saving...
31521:M 01 Jul 11:17:08.066 * Background saving started by pid 18548
18548:C 01 Jul 11:17:08.082 # Failed opening the RDB file root (in server root dir /etc/cron.d) for saving: Permission denied
31521:M 01 Jul 11:17:08.166 # Background saving error

2，解决办法：
1）命令行修改
config set stop-writes-on-bgsave-error no
2）修改配置文件
vim redis.conf
stop-writes-on-bgsave-error 把后面的yes设置为no即可
#此办法需要重启redis
